Key Takeaways About Sinsferk

  • Prescription only: Sinsferk 15 mg film-coated tablets are dispensed only on a valid prescription issued by a qualified healthcare professional.
  • Follow the dose exactly: Take the number of tablets prescribed, at the times indicated, for as long as your doctor tells you — do not change the dose on your own.
  • Tell your doctor about other medicines: Interactions with other prescription medicines, over-the-counter products, herbal remedies and supplements are possible and may alter how Sinsferk works or cause side effects.
  • Report side effects early: Any sign of allergic reaction, unusual bleeding, severe abdominal pain, jaundice, or new mental-health symptoms should be reported to a doctor without delay.
  • Do not stop abruptly: Unless your doctor instructs you otherwise, continue taking Sinsferk for the full prescribed course even if you feel better, and discuss any plans to stop or pause treatment in advance.

What Is Sinsferk and What Is It Used For?

Sinsferk is a prescription-only medicine that contains the active substance sinsferk and is supplied as 15 mg film-coated tablets for oral use. It is prescribed by a doctor for a specific medical condition based on your individual diagnosis, and the exact indication, dose and duration will be explained to you when the medicine is prescribed.

Sinsferk is a prescription medicine intended to be used under the direction of a qualified healthcare professional. Each film-coated tablet contains 15 milligrams of the active substance sinsferk, together with inactive ingredients (excipients) that form the tablet matrix and the outer film coating. The film coating helps to mask any unpleasant taste, protects the active substance and makes the tablet easier to swallow. Because Sinsferk has been classified as prescription-only medicine (Rx), it can only be obtained from a pharmacy with a valid prescription from a licensed prescriber such as a physician, specialist or nurse prescriber.

The precise therapeutic indication — meaning the medical condition or symptom that Sinsferk is approved to treat — is set out in the Summary of Product Characteristics (SmPC) and patient information leaflet issued by the marketing-authorisation holder. These documents are the authoritative source of information about Sinsferk and are regularly updated as new clinical data become available. Your prescribing doctor will tell you why Sinsferk has been chosen for your specific situation and how it fits into the overall management plan for your condition. You should only use Sinsferk for the indication for which it has been prescribed to you, and you should not share your tablets with another person, even if that person appears to have a similar condition.

Medicines like Sinsferk are typically developed to address a particular biological target, receptor or pathway in the body. The aim of such targeted therapy is to modify a specific disease process rather than produce a broad, non-specific effect. As with any prescription medicine, the decision to use Sinsferk is based on a careful weighing of expected clinical benefits against potential risks, taking into account your age, overall health, other medical conditions and the medicines you are already taking. This risk-benefit assessment is unique to each patient and is one of the reasons why Sinsferk must not be taken without medical supervision.

How Sinsferk Is Supplied

Sinsferk is supplied as round or oval film-coated tablets of 15 mg strength. The exact appearance (colour, shape, markings and scoring) is described in the patient information leaflet and may vary slightly between batches and markets, but the active ingredient and strength remain the same. The tablets are usually packaged in blister strips inside a cardboard carton, together with the patient information leaflet. Some packs may instead be provided in plastic bottles with a child-resistant closure. Always check that the carton, blister and leaflet identify the medicine as Sinsferk 15 mg before starting treatment.

Important to understand:

This article provides general, evidence-based information about prescription medicines that are supplied as 15 mg film-coated tablets. The specific indication, mechanism of action and clinical trial evidence for Sinsferk are set out in the authoritative Summary of Product Characteristics and patient information leaflet issued by the marketing-authorisation holder. Always follow those documents and your doctor's instructions, which take precedence over any general information on this page.

What Should You Know Before Taking Sinsferk?

Before starting Sinsferk, tell your doctor about all other medicines you are taking, any allergies, chronic medical conditions, a planned or current pregnancy, and breastfeeding. Sinsferk should not be used by anyone who is hypersensitive to the active substance or any of the excipients, and your doctor will decide whether treatment is appropriate for your individual situation.

Sinsferk is intended to be used only after a careful medical assessment. Your prescribing doctor will ask questions about your medical history, current symptoms, existing diagnoses and any previous reactions to medicines. This helps identify situations in which Sinsferk may not be suitable or where dose adjustments, additional monitoring or alternative treatments should be considered. Being open and thorough during this conversation is essential for safe and effective treatment.

Contraindications

Do not take Sinsferk if any of the following applies to you:

  • You are allergic (hypersensitive) to the active substance sinsferk or to any of the other ingredients of the tablet listed in the package leaflet.
  • You have previously had a serious adverse reaction to a medicine in the same therapeutic group, as identified by your prescribing doctor.
  • Your doctor has told you that Sinsferk is not suitable because of another medical condition, laboratory result or concurrent medicine.

If you are not sure whether any of the above applies to you, speak with your doctor or pharmacist before taking Sinsferk. Signs of an allergic reaction may include skin rash or hives, swelling of the face, lips, tongue or throat, itching, difficulty breathing, rapid heartbeat or a sudden drop in blood pressure. These symptoms require urgent medical attention.

Warnings and Precautions

Talk to your doctor or pharmacist before taking Sinsferk if any of the following apply to you:

  • Kidney or liver problems: These organs are responsible for clearing most oral medicines from the body, and impairment may affect how Sinsferk is eliminated. Your doctor may adjust the dose or choose an alternative.
  • Heart disease, arrhythmia or recent cardiovascular events: Some medicines can affect heart rhythm or blood pressure, and pre-existing cardiac conditions may require closer monitoring.
  • Diabetes or metabolic disorders: Changes in blood sugar, lipids or electrolytes are possible with many medicines; your regular blood tests may need to be reviewed.
  • Mental-health conditions: A history of depression, anxiety, bipolar disorder or suicidal thoughts should be shared with your doctor so any new or worsening symptoms can be recognised early.
  • History of bleeding disorders or use of anticoagulants: Tell your doctor if you bruise easily, have had gastrointestinal bleeding, or use medicines that thin the blood.
  • History of seizures or neurological disease: Certain medicines can lower the seizure threshold or interact with anti-epileptic drugs.
  • Recent vaccinations or planned immunisations: The timing of vaccines may need to be coordinated with your treatment, particularly for live vaccines.
  • Upcoming surgery or anaesthesia: Always inform surgical and anaesthetic teams that you are taking Sinsferk, as temporary dose changes may be required.

Your doctor may order baseline blood tests, liver- and kidney-function panels, an electrocardiogram (ECG) or other investigations before you begin Sinsferk, depending on your individual health profile. Follow-up tests may be arranged at intervals during treatment to confirm that the medicine continues to be safe and effective for you. Keeping all scheduled appointments and blood-test visits is an important part of treatment.

Seek Urgent Medical Help If…

Contact a doctor or go to the emergency department immediately if you experience symptoms of a severe allergic reaction (difficulty breathing, swelling of the face or throat, collapse), signs of a serious skin reaction (blistering, peeling, sores in the mouth or eyes), yellowing of the skin or eyes (possible liver injury), unusual or persistent bleeding, severe chest pain, fainting, or new thoughts of self-harm. These reactions are rare but need immediate assessment.

Pregnancy and Breastfeeding

If you are pregnant, think you may be pregnant, are trying to conceive, or are breastfeeding, tell your doctor before starting Sinsferk. Many medicines can cross the placenta or pass into breast milk, and the safety of Sinsferk during pregnancy and lactation must be assessed individually. Your doctor may:

  • Arrange a pregnancy test before starting treatment.
  • Discuss effective contraception options to use during treatment and for a defined period afterwards.
  • Review whether an alternative medicine with a better documented safety profile in pregnancy is available.
  • Recommend temporary interruption of breastfeeding or choose an alternative therapy, depending on the situation.

If you become pregnant while taking Sinsferk, do not stop the medicine on your own; contact your doctor promptly so that your treatment can be reviewed in the light of your pregnancy.

Children and Adolescents

Sinsferk is intended for adult use unless your doctor specifies otherwise. The safety and efficacy of Sinsferk in children and adolescents may not have been formally established in all age groups, and paediatric use should only occur under the direction of a specialist familiar with the medicine and the underlying condition. Never give Sinsferk to a child unless it has been prescribed specifically for that child.

Elderly Patients

Older adults may be more sensitive to the effects of many prescription medicines because of age-related changes in kidney and liver function, as well as the presence of other chronic conditions and concurrent medicines (polypharmacy). Your doctor may start you on a lower dose, schedule closer monitoring, or review your overall medication list to reduce the risk of interactions and side effects.

Driving and Operating Machinery

Some patients may experience dizziness, drowsiness, blurred vision, fatigue or impaired concentration during treatment with prescription medicines. Do not drive, operate heavy machinery, climb ladders or perform other activities that require full alertness until you know how Sinsferk affects you personally. If any such symptoms occur, avoid these activities and inform your doctor.

Alcohol, caffeine and grapefruit juice:

Ask your doctor or pharmacist whether alcohol, large amounts of caffeine or grapefruit juice should be avoided during treatment with Sinsferk. Grapefruit products in particular can alter the metabolism of a wide range of prescription medicines through their effect on the CYP3A4 enzyme in the gut wall.

How Does Sinsferk Interact with Other Drugs?

Tell your doctor or pharmacist about all medicines you take, have recently taken or plan to take, including over-the-counter products, herbal remedies and supplements. Drug interactions can change how Sinsferk works, increase the risk of side effects or affect the safety and effectiveness of your other medicines.

Interactions between medicines are one of the most important reasons why Sinsferk must be used under medical supervision. Two or more medicines can interact in several different ways: one may alter how much of the other reaches the bloodstream, how it is broken down by the liver, how it is eliminated by the kidneys, or how it acts at a particular receptor. Some interactions are trivial, but others can cause serious harm, including reduced efficacy, additive toxicity or unexpected new side effects.

Keeping an up-to-date medication list — including prescription medicines, pharmacy-only and general-sales medicines, vitamins, minerals, herbal supplements and traditional remedies — helps your doctor and pharmacist screen for interactions whenever a new medicine is added. Tell them also about any recreational drug use, as interactions can occur with substances such as alcohol, nicotine, cannabis and street drugs. Every pharmacy visit is an opportunity to review your list and ask about possible interactions.

Major Interactions

The following table summarises the main categories of medicines that commonly interact with prescription oral tablets such as Sinsferk. Your prescribing doctor and pharmacist have access to more detailed, product-specific interaction information and will check your regimen carefully.

Examples of Clinically Relevant Interaction Categories
Interacting Drug/Class Effect Recommendation
Strong CYP3A4 inhibitors (e.g. itraconazole, ketoconazole, clarithromycin, ritonavir) May increase blood levels of Sinsferk and raise the risk of side effects. Avoid combination when possible; otherwise, dose adjustment or extra monitoring may be needed.
Strong CYP3A4 inducers (e.g. rifampicin, carbamazepine, phenytoin, St John's wort) May reduce blood levels of Sinsferk and decrease its therapeutic effect. Avoid or use an alternative therapy; inform your doctor if you already use any of these.
Anticoagulants and antiplatelet agents (e.g. warfarin, DOACs, aspirin, clopidogrel) Possible increased bleeding risk depending on the medicine's pharmacology. Use only under medical supervision; report any unusual bruising or bleeding.
QT-prolonging medicines (e.g. certain antibiotics, antipsychotics, antiarrhythmics) Combined use can increase the risk of abnormal heart rhythms. Avoid combinations where possible; your doctor may order an ECG and electrolyte checks.
CNS depressants (benzodiazepines, opioid analgesics, sedating antihistamines, alcohol) Possible additive sedation, dizziness or respiratory depression. Use together with caution; avoid operating machinery until effects are known.
Grapefruit juice Inhibits intestinal CYP3A4 and can raise levels of many oral medicines. Ask your pharmacist whether grapefruit should be avoided during treatment with Sinsferk.

Minor and Potential Interactions

In addition to major interactions, there are many more minor or less common interactions that your pharmacist can identify during routine dispensing. Examples include:

  • Antacids, sucralfate or iron supplements — these can reduce absorption of some medicines if taken at the same time; separate doses by a few hours where advised.
  • Hormonal contraceptives — some medicines can reduce contraceptive efficacy; additional non-hormonal contraception may be recommended.
  • Herbal supplements — products such as St John's wort, echinacea, ginkgo and high-dose garlic can cause unexpected interactions with prescription medicines.
  • Over-the-counter pain relievers — frequent use of NSAIDs such as ibuprofen or naproxen may increase the risk of gastrointestinal or renal side effects.
  • Caffeine, tobacco and recreational substances — mention these honestly to your doctor, as they may influence your treatment plan.
Bring a list to every appointment:

A simple written or digital list of all medicines, supplements, doses and frequencies makes it far easier for any healthcare professional to spot interactions with Sinsferk. Many pharmacies can print a current medication list on request.

What Is the Correct Dosage of Sinsferk?

The correct dose of Sinsferk depends on the condition being treated, your age, weight and kidney or liver function, and is decided by your prescribing doctor. Sinsferk 15 mg film-coated tablets should be swallowed whole with water and taken exactly according to the instructions on the prescription label and in the patient information leaflet.

Dosing of Sinsferk is individualised. There is no single "one-size-fits-all" dose, because the appropriate amount depends on many factors including the indication, the severity of the condition, your body weight, other medicines, and your kidney and liver function. The specific recommended dose, frequency and duration of treatment are set out in the Summary of Product Characteristics and will be explained to you by the prescribing doctor.

How to Take Sinsferk Tablets

General Administration Principles

Swallow each 15 mg film-coated tablet whole with a glass of water. Do not chew, crush or divide the tablet unless your pharmacist or doctor tells you that it is safe to do so. The tablet is designed to release the active substance gradually, and damaging the film coating can change how the medicine is absorbed. Take Sinsferk at about the same time each day to maintain steady levels in the body and to help you remember. Your doctor will advise whether Sinsferk should be taken with food, on an empty stomach or without regard to meals, as this varies between products.

Adults

Typical Adult Dose

For most prescription oral tablets of this strength, the adult dose is usually one or more 15 mg tablets once or twice daily, depending on the indication and individual response. Your doctor may start at a lower dose and gradually increase it (titration) to find the dose that works best with the fewest side effects. Never take more Sinsferk than has been prescribed, and do not take two doses close together to "catch up" on a forgotten tablet.

Children

Paediatric Use

Use of Sinsferk in children and adolescents should only occur under the supervision of a specialist familiar with the medicine and the underlying condition. If Sinsferk has been prescribed for a child, the dose will be calculated based on the child's weight or body surface area, age and clinical status. Do not use an adult dose in children. If you have not been given specific paediatric instructions, do not give Sinsferk to a child.

Elderly

Patients Aged 65 and Over

Older adults often take multiple medicines and may have reduced kidney or liver function. Your doctor may therefore choose a lower starting dose, schedule more frequent follow-up appointments, or order regular laboratory tests to monitor for side effects. If you are taking Sinsferk and notice new symptoms such as confusion, dizziness, unsteadiness or falls, contact your doctor promptly.

Patients with Kidney or Liver Impairment

Organ Dysfunction Considerations

In patients with significantly reduced kidney or liver function, the body may clear Sinsferk more slowly, leading to higher than expected blood levels. Your doctor may order blood tests such as creatinine, estimated glomerular filtration rate (eGFR), ALT, AST and bilirubin before and during treatment. Based on these results, the dose may need to be reduced, the dosing interval extended, or treatment avoided entirely in favour of an alternative medicine.

Missed Dose

If you forget to take a dose of Sinsferk, take it as soon as you remember unless it is almost time for the next scheduled dose. In that case, skip the missed dose and continue with your normal schedule. Do not take a double dose to make up for a forgotten tablet, because this can increase the risk of side effects without improving the benefit of the medicine. If you frequently forget doses, consider using a pill organiser or setting reminders on your phone, and discuss adherence strategies with your pharmacist.

Overdose

If you or someone else has taken more Sinsferk than prescribed, contact a doctor, poison information centre or emergency service immediately, even if there are no obvious symptoms. Take the tablet packaging, the patient information leaflet and any remaining tablets with you to the hospital so that healthcare staff can identify exactly which medicine and strength has been taken. Symptoms of overdose may include severe dizziness, confusion, abnormal heart rhythm, low blood pressure, nausea, vomiting, seizures or loss of consciousness. Treatment is generally supportive, with close monitoring of vital signs and specific measures based on the clinical picture.

Stopping Treatment

Do not stop taking Sinsferk on your own, even if you feel better or notice mild side effects. Abrupt discontinuation of some prescription medicines can cause a rebound of the underlying condition or withdrawal symptoms. If you have reasons to stop treatment — for example, because of side effects, cost, planned pregnancy or an upcoming procedure — speak to your doctor first. Your doctor can either adjust the regimen, switch you to an alternative medicine, or taper the dose slowly to minimise problems.

What Are the Side Effects of Sinsferk?

Like all medicines, Sinsferk can cause side effects, although not everyone experiences them. Common effects typically include gastrointestinal symptoms, headache, dizziness or fatigue. Rare but serious reactions such as severe allergic reactions, liver or kidney problems, and abnormal heart rhythms require immediate medical attention.

The risk of side effects with any prescription medicine depends on the dose, the duration of treatment, individual patient factors and the use of other medicines. Many side effects are mild and short-lived, disappearing as your body adjusts to Sinsferk. However, some reactions may be serious and require immediate medical review. Knowing what to watch for helps you act quickly when needed.

Seek Immediate Medical Attention If…

Stop Sinsferk and seek emergency medical help if you experience signs of a severe allergic reaction (difficulty breathing, swelling of the face, lips, tongue or throat, a rapidly spreading rash with blistering or peeling), severe or persistent chest pain, fainting, sudden severe headache, slurred speech, confusion, weakness on one side of the body, yellowing of the skin or eyes, dark urine, persistent severe abdominal pain, vomiting blood, black tarry stools, or new thoughts of self-harm.

Side Effects by Frequency

The European Medicines Agency uses the following standard frequency categories to describe how often side effects have been reported in clinical studies and post-marketing use. The lists below reflect the kinds of reactions commonly recorded for oral prescription medicines and should be interpreted in the light of the official Sinsferk package leaflet.

  • Dangerous heart-rhythm disturbances including QT prolongation
  • New or worsening suicidal thoughts or behaviour

What to Do if You Experience Side Effects

Keep a simple diary of any new or unusual symptoms that start after you begin taking Sinsferk — when they occur, how severe they are, how long they last, and whether they are linked to a particular dose or activity. This information is extremely helpful to your doctor or pharmacist. For mild and short-lived effects such as nausea or headache, practical measures (taking the tablet with food, increasing water intake, adjusting the timing) may help. For more troublesome or persistent symptoms, your doctor may adjust the dose, switch you to a different medicine, or advise you to stop Sinsferk.

If you experience a serious side effect, especially one listed in the warning box above, seek urgent medical attention. Serious reactions are uncommon but need rapid assessment to minimise long-term harm. You can also report suspected side effects to your national pharmacovigilance authority — for example, the Yellow Card Scheme in the United Kingdom, MedWatch in the United States, or the EMA EudraVigilance network in the European Union. Reporting helps build a more complete safety profile for Sinsferk over time.

How Should You Store Sinsferk?

Store Sinsferk 15 mg tablets in the original package at room temperature, protected from light and moisture. Keep the medicine out of the sight and reach of children, and do not use it after the expiry date printed on the carton and blister.

Correct storage helps to preserve the quality, potency and safety of Sinsferk tablets throughout the product's shelf life. Oral tablets are generally sensitive to heat, direct sunlight and humidity, and the original packaging is designed to protect them from these conditions. Never transfer Sinsferk tablets to unmarked containers or mix them with other medicines, as this can cause confusion, accidental overdose or missed doses.

Recommended Storage Conditions

  • Keep Sinsferk in the original blister or bottle until you are ready to take each dose. The packaging protects the tablets from light and moisture and preserves the batch number and expiry date.
  • Store at room temperature, usually below 25–30°C, unless the package leaflet specifies otherwise.
  • Keep away from direct sunlight, radiators, ovens and cooking surfaces. Do not store Sinsferk in the bathroom, as humidity can damage the tablets; a bedroom drawer or kitchen cupboard (away from heat sources) is usually more suitable.
  • Do not refrigerate or freeze Sinsferk unless the leaflet tells you to.
  • If you travel, carry the medicine in its original packaging together with a copy of your prescription. Avoid leaving it in a hot car or checked luggage during air travel.

Keep Out of Reach of Children

Accidental ingestion of prescription medicines by children is a common cause of emergency department visits. Always keep Sinsferk out of the sight and reach of children, preferably in a locked cabinet or a high shelf. Never refer to tablets as "sweets" to encourage a child to swallow them. If you suspect a child has accidentally taken Sinsferk, even one tablet, contact your local poison information centre or emergency service immediately.

Expiry Date and Disposal

Do not use Sinsferk after the expiry date stated on the carton and blister. The expiry date refers to the last day of that month. Expired medicine may have lost potency or may no longer be safe. If you have tablets left over after completing treatment, or if the medicine has passed its expiry date, do not throw them in the household waste or flush them down the toilet or sink. Instead, return unused medicines to your local pharmacy, which will dispose of them safely through an approved pharmaceutical-waste route. Proper disposal helps protect both the environment and other members of the household.

Batch numbers and recalls:

If there is ever a safety alert or product recall, regulators publish the affected batch numbers of the medicine. Keeping Sinsferk in its original packaging makes it easier to check your batch against any official notice and to return affected products to the pharmacy.

What Does Sinsferk Contain?

Each Sinsferk film-coated tablet contains the active ingredient sinsferk 15 mg together with pharmaceutical excipients used to form the tablet core and the outer film coating. The full list of ingredients is provided in the patient information leaflet supplied with the medicine.

Knowing what is inside Sinsferk is particularly important if you have allergies, intolerances, religious dietary restrictions or specific medical conditions such as diabetes or lactose intolerance. The complete list of ingredients (active substance plus excipients) is always given in the package leaflet, and your pharmacist can help you interpret it.

Active Ingredient

Each Sinsferk 15 mg film-coated tablet contains:

  • Sinsferk 15 mg (the active substance responsible for the therapeutic effect).

Typical Excipients (Inactive Ingredients)

Film-coated tablets like Sinsferk are typically manufactured with a combination of the following inactive ingredients, which serve specific technical purposes during manufacturing and administration:

  • Tablet core fillers and diluents: for example microcrystalline cellulose, lactose monohydrate or mannitol, which provide the bulk of the tablet.
  • Binders: such as povidone or hypromellose, used to hold the powders together during compression.
  • Disintegrants: for example crospovidone, croscarmellose sodium or sodium starch glycolate, which help the tablet break apart in the stomach or intestine.
  • Lubricants and glidants: such as magnesium stearate and colloidal silicon dioxide, used to control the tablet manufacturing process.
  • Film-coating agents: typically containing hypromellose, polyethylene glycol, titanium dioxide and iron-oxide pigments, which form the outer coat of the tablet.

The exact list of excipients for your specific pack of Sinsferk is always printed in the patient information leaflet. If you are aware of a particular allergy or intolerance — such as lactose intolerance or an allergy to azo dyes — ask your pharmacist to confirm that the product is suitable for you before dispensing.

Important Composition Notes

  • Lactose: If the leaflet indicates that Sinsferk contains lactose, patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take it.
  • Sodium: The sodium content of a single tablet is usually very low (less than 1 mmol per dose, equivalent to "essentially sodium-free"), but patients on a controlled sodium diet should check the leaflet.
  • Azo dyes and other colourants: Some film coatings contain azo dyes that can trigger allergic reactions in a small number of patients.
  • Gluten: Film-coated tablets are typically gluten-free, but individuals with coeliac disease should confirm this with the leaflet.

Appearance and Packaging

Sinsferk 15 mg tablets are film-coated tablets supplied in blister strips or plastic bottles, packaged in a cardboard carton together with the patient information leaflet. Check the colour, markings, blister imprint and expiry date each time you start a new pack to confirm that you have received the correct medicine. Contact your pharmacist if anything looks different from previous packs, if tablets are broken or discoloured, or if the seal appears damaged.

Frequently Asked Questions About Sinsferk

Sinsferk is a prescription-only medicine supplied as 15 mg film-coated tablets for oral use. The exact indication, dose and duration of treatment will be determined by your prescribing doctor based on your diagnosis, medical history and individual response. You should only use Sinsferk for the condition it has been prescribed for and always follow the instructions in the patient information leaflet supplied with your medicine.

Take Sinsferk exactly as prescribed by your doctor. Film-coated tablets should be swallowed whole with a glass of water, unless your doctor or pharmacist gives you different instructions. Do not crush, chew or divide the tablet unless specifically told it is safe to do so. Take your dose at roughly the same time each day to maintain steady levels of the medicine in your body and to help you remember.

If you forget a dose, take it as soon as you remember unless it is almost time for your next scheduled dose. In that case, skip the missed dose and continue with your usual schedule. Never take a double dose to make up for a forgotten tablet. If you are unsure what to do, contact your doctor or pharmacist for advice.

Alcohol may interact with many prescription medicines by changing how they are absorbed or metabolised, or by increasing the risk of side effects such as drowsiness, dizziness or liver strain. Always ask your prescribing doctor or pharmacist whether it is safe to drink alcohol while taking Sinsferk and, if so, in what amount.

If you are pregnant, think you may be pregnant, are planning a pregnancy or are breastfeeding, tell your doctor before starting Sinsferk. Many medicines require careful risk-benefit assessment during pregnancy and lactation because they may pass through the placenta or into breast milk. Your healthcare professional will decide whether the potential benefit of treatment outweighs any possible risk to the baby, and whether an alternative therapy should be considered.

Store Sinsferk in the original packaging to protect it from light and moisture. Keep the tablets at room temperature, typically below 25–30°C, unless the carton states otherwise. Always keep Sinsferk out of the sight and reach of children. Do not use the tablets after the expiry date printed on the pack, and return unused medicine to a pharmacy for safe disposal rather than throwing it in the household waste or flushing it.

Tell your doctor and pharmacist about all medicines you take or have recently taken, including prescription drugs, over-the-counter products, herbal remedies and dietary supplements. Some medicines can increase or decrease the effect of Sinsferk, and others may share side effects. Your healthcare professional will check your list for clinically relevant interactions and adjust treatment if necessary.
