Side Effects & Warnings
What is Tamiflu
Tamiflu is a prescription only medicine for treating or preventing types of influenza such as swine flu. Tamiflu belongs to a group of medicines named “neuraminidase inhibitors”. These medicines prevent the influenza virus from spreading inside the body and so help to ease or prevent the symptoms arising from the influenza virus infection. Influenza is an infection caused by the influenza virus.
Signs Of Influenza (The Flu)
The signs (symptoms) of influenza include the sudden onset of fever (more than 37.8°C), cough, runny or stuffy nose, headaches, muscle aches and often extreme fatigue. These symptoms may also be caused by infections other than influenza. True influenza infection only occurs during annual outbreaks (epidemics) at times when influenza viruses are spreading in the local community. Outside of the epidemic period, these symptoms will mainly be caused by a different type of infection or illness.
How to take Tamiflu
Always take Tamiflu exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure. Take Tamiflu as soon as you get the prescription as this will help to slow the spread of the influenza virus in the body. Swallow Tamiflu capsules whole with water. Do not break or chew Tamiflu capsules. The usual dose is as follows:
Adolescents (13 to 17 years of age) and adults: For treatment of influenza take one capsule as soon as you get the prescription and then take one capsule twice a day (usually it is convenient to take one in the morning and one in the evening for five days). It is important to complete the whole 5 day course, even if you start to feel better quickly. 30 mg and 45 mg capsules can be used by adults and adolescents as an alternative to 75 mg capsules.
Infants 1 year of age and older, and children 2 to 12 years of age: Tamiflu oral suspension or 30 mg and 45 mg capsules can be used instead. Children weighing more than 40 kg and who can swallow capsules may take Tamiflu 75 mg capsules twice daily for 5 days.
Infants below 12 months of age: Limited pharmacokinetic and safety data are available for children less than 2 years of age. Pharmacokinetic modeling was undertaken using these data in addition to data from studies in adults and children older than 1 year of age. The results demonstrate that doses of 3 mg/kg twice daily for infants aged 3 to 12 months and 2.5 mg/kg twice daily for infants aged between 1 and 3 months provide exposures similar to those shown to be clinically efficacious in adults and children older than 1 year of age (see table below for weight-based dosing recommendations). There are currently no data available in infants less than 1 month of age using Tamiflu.
Age Recommended dose for 5 days (Treatment)
Tamiflu can also be used for prevention of influenza following exposure to an infected individual,
such as family members.
Adolescents (13 to 17 years of age) and adults: When used to prevent influenza following
exposure to an infected individual, such as family members, Tamiflu should be taken once daily
for 10 days. It is best to take this dose in the mornings with breakfast.
Infants 1 year of age and older and children 2 to 12 years of age: Tamiflu oral suspension or
30 mg and 45 mg capsules can be used instead.
Children weighing more than 40 kg and can swallow capsules may take Tamiflu 75 mg capsules
once daily for 10 days.
Your doctor will recommend the length of time to continue taking Tamiflu, if it is prescribed to prevent influenza. Infants below 12 months of age: The recommended prophylaxis dose for infants less than 12 months of age during a pandemic influenza outbreak is half of the daily treatment dose. This is based upon clinical data in children older than 1 year of age and adults showing that a prophylaxis dose equivalent to half the daily treatment dose is clinically efficacious for the prevention of influenza. The following weight-adjusted dosing prophylaxis regimens are recommended for infants below 1 year of age:
Age Recommended dose for 10 days (Prevention)
