Oseltamivirum
Oseltamivir Stada contains oseltamivir, which belongs to a group of medicines called neuraminidase inhibitors. These medicines prevent the spread of the influenza virus in the body. They help to alleviate symptoms or prevent their occurrence in the event of influenza virus infection.
Influenza is an infectious disease caused by a virus. Influenza symptoms often include sudden onset of fever (above 37.8°C), cough, runny or stuffy nose, headache, muscle pain, and extreme fatigue. Such symptoms can also be caused by other infections. True influenza infection occurs only during annual outbreaks of the disease (epidemics), when the influenza virus spreads in the local environment. Outside of epidemic periods, flu-like symptoms are usually the result of other diseases.
In such a situation, contact a doctor. Do not take Oseltamivir Stada.
Before taking Oseltamivir Stada, inform the doctor who prescribed the medicine:
During treatment with Oseltamivir Stada, immediately inform the doctor:
Oseltamivir Stada is not a vaccine: it is used to treat an infection or prevent the spread of the influenza virus. The vaccine provides antibodies against the virus. Oseltamivir Stada does not affect the effectiveness of influenza vaccination, and the doctor may prescribe both products to the patient.
Tell your doctor or pharmacist about all medicines you are taking now or have taken recently. This includes medicines obtained without a prescription. The following medicines are particularly important:
Inform your doctor if you are pregnant, think you may be pregnant, or plan to become pregnant, so that your doctor can decide whether Oseltamivir Stada is a suitable medicine for you.
The effect of Oseltamivir Stada on breastfed infants is unknown. Inform your doctor if you are breastfeeding, so that they can decide whether Oseltamivir Stada is a suitable medicine for you.
Consult your doctor or pharmacist before taking this medicine.
Oseltamivir Stada does not affect the ability to drive and use machines.
The medicine contains less than 1 mmol (23 mg) of sodium per capsule, i.e., the medicine is considered "sodium-free".
Always take this medicine exactly as your doctor has told you. If you are not sure, ask your doctor or pharmacist.
Oseltamivir Stada should be taken as soon as possible, preferably within the first two days of the onset of influenza symptoms.
For the treatment of influenza, take two doses a day, usually one in the morning and one in the evening. It is essential to complete the entire 5-day treatment cycle, even if the patient's condition improves quickly.
In patients with weakened immune systems, treatment will be continued for 10 days.
For the prevention of influenza or after contact with an infected person, take one dose a day for 10 days, preferably in the morning during breakfast.
In special situations, such as the spread of influenza or if the patient has a weakened immune system, treatment will last up to 6 weeks or 12 weeks.
The recommended dose is calculated based on the patient's body weight. Take the number of capsules or oral suspension prescribed by your doctor.
Body weight | Influenza treatment: dose for 5 days | Influenza treatment (patients with weakened immunity): dose for 10 days* | Influenza prevention: dose for 10 days |
Over 40 kg | 75 mg** twice a day | 75 mg** twice a day | 75** mg once a day |
*In patients with weakened immune systems, treatment lasts 10 days.
**The 75 mg dose may consist of a 30 mg capsule and a 45 mg capsule.
Body weight | Influenza treatment: dose for 5 days | Influenza treatment (patients with weakened immunity): dose for 10 days* | Influenza prevention: dose for 10 days |
10 to 15 kg | 30 mg twice a day | 30 mg twice a day | 30 mg once a day |
Over 15 kg to 23 kg | 45 mg twice a day | 45 mg twice a day | 45 mg once a day |
Over 23 kg to 40 kg | 60 mg twice a day | 60 mg twice a day | 60 mg once a day |
Over 40 kg | 75 mg** twice a day | 75 mg** twice a day | 75 mg** once a day |
*In children with weakened immune systems, treatment lasts 10 days.
**The 75 mg dose may consist of a 30 mg capsule and a 45 mg capsule.
The decision to administer Oseltamivir Stada to infants under 1 year of age for prophylaxis during an influenza pandemic should be made after evaluating the potential benefits and risks for the infant.
Body weight | Influenza treatment: dose for 5 days | Influenza treatment (patients with weakened immunity): dose for 10 days* | Influenza prevention: dose for 10 days |
3 kg to 10+ kg | 3 mg/kg body weight**, twice a day | 3 mg/kg body weight**, twice a day | 3 mg/kg** once a day |
In infants with weakened immune systems, treatment lasts 10 days.
**mg/kg = mg per kilogram of infant body weight. For example:
for a 6-month-old infant weighing 8 kg, the dose is 8 kg x 3 mg/kg = 24 mg
Swallow the capsules whole with water. Do not divide or crush the capsules.
Oseltamivir Stada can be taken with or without food. Taking the medicine with food reduces the risk of nausea or vomiting.
Patients who have difficulty swallowing capsulesmay use oseltamivir in the form of an oral suspension. If the patient requires a suspension but it is not available at the pharmacy, it is possible to prepare a liquid form of Oseltamivir Stada from capsules. Instructions, see Preparing a liquid form of Oseltamivir Stada at home.
Stop taking Oseltamivir Stada and contact a doctor or pharmacist immediately.
In most cases of overdose, no adverse reactions have been reported. If they were reported, they were similar to adverse reactions after taking the recommended doses, as described in section 4.
Overdose has been reported more frequently after administration of Oseltamivir Stada to children than to adults and adolescents. Caution should be exercised when preparing a liquid form of Oseltamivir Stada for children and when administering Oseltamivir Stada to children in the form of capsules or liquid.
Do not take a double dose to make up for a missed capsule.
There are no adverse reactions if treatment with Oseltamivir Stada is stopped.
However, if treatment with Oseltamivir Stada is stopped earlier than recommended by the doctor, influenza symptoms may return. Always complete the treatment as recommended by the doctor.
If you have any further questions about the use of this medicine, ask your doctor or pharmacist.

Commercially available oseltamivir in the form of an oral suspension (6 mg/mL) is the preferred product for children and adolescents and for adult patients who have difficulty swallowing capsules or require smaller doses. If oseltamivir oral suspension is not available on the market, the pharmacist can prepare a suspension (6 mg/mL) from Oseltamivir Stada capsules. If the pharmacy-prepared suspension is also not available, patients can prepare a suspension from capsules at home.
Ensure that oral dosing syringes(oral syringes) of suitable volume and graduation are available for administering the suspension prepared in the pharmacy and for the procedures related to preparing the product at home. In both cases, it is best if the syringes are marked with the correct volumes. When preparing the solution at home, use separate syringes to draw the correct amount of water and to measure the Oseltamivir Stada mixture with water.
To measure 5.0 mL of water, use 5 mL or 10 mL syringes.
