TAMIFLU

Oseltamivir capsule 75mg

What Tamiflu is used for

Tamiflu contains the active ingredient oseltamivir.

Tamiflu is used to treat the flu (an infection caused by the influenza virus).

Tamiflu belongs to a group of medicines called neuraminidase inhibitors. These medicines attack the influenza virus and prevent it from spreading inside your body and to other people.

Taking Tamiflu means that you feel better faster because Tamiflu treats the cause of flu at its source, rather than simply reducing the symptoms.

You will also be less likely to develop complications of flu, such as bronchitis, pneumonia and sinusitis.

Typical symptoms of flu include fever, headache, muscle weakness, sore throat, cough and generally feeling unwell.

Ask your doctor if you have any questions about why Tamiflu has been prescribed for you.

Tamiflu is not addictive.

This medicine is available only with a doctor's prescription.

Before you take Tamiflu

Do not take Tamiflu if:

• you have had an allergic reaction to Tamiflu or any ingredients listed at the end of this leaflet
• the package is torn or shows signs of tampering
• the expiry date printed on the pack has passed. If you take this medicine after the expiry date has passed, it may not work as well.

If you are not sure if you should be taking Tamiflu, talk to your doctor.

Use in children

Do not give Tamiflu to children under 12 years.

Safety and effectiveness in children under the age of 12 years have not been established.

Before you start to take it, tell your doctor if:

• you are over 65 years of age. There is limited data for Tamiflu in people over 65 years of age. If you are over this age your doctor may decide not to prescribe Tamiflu.
• you are pregnant or plan to become pregnant. It is not known whether Tamiflu is harmful to an unborn baby when taken by a pregnant woman. If there is a need to take Tamiflu when you are pregnant your doctor will discuss the risks and benefits to you and the unborn baby.
• you are breast-feeding or plan to breast-feed. It is not known whether Tamiflu passes into breast milk. Your doctor will discuss the risks and benefits of using Tamiflu if you are breast-feeding.
• you have any other health problems, especially any of the following:
  • kidney disease
  • chronic heart disease
  • lung disease. Your doctor may decide not to prescribe Tamiflu.
• you are allergic to any other medicines, foods, dyes or preservatives.

If you have not told your doctor about any of the above, tell your doctor before you start taking Tamiflu.

Taking other medicines

Tamiflu is not a substitute for a flu vaccination. You should continue receiving an annual flu vaccination according to guidelines on immunization practices that your doctor can discuss with you.

Tell your doctor if you are taking any other medicines, including any that you have bought from a pharmacy, supermarket or health food shop.

These medicines may be affected by Tamiflu, or may affect how well it works. You may need to use different amounts of your medicine, or you may need to take different medicines. Your doctor will advise you.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking Tamiflu.

It is safe to take paracetamol and cough medicines with Tamiflu.

How to take Tamiflu

Follow all directions given to you by your doctor or pharmacist carefully.

They may differ from the information contained in this leaflet.

Start taking Tamiflu as soon as possible after you have been diagnosed with the flu. The earlier you start treatment with Tamiflu, the shorter will be the duration of your flu.

How much to take

Take Tamiflu exactly as your doctor has prescribed.

The usual dose is one Tamiflu capsule twice a day.

How to take it

Swallow capsules whole with a glass of water with or without food.

It does not matter whether you take Tamiflu with food or not. However, if Tamiflu upsets your stomach, it is better to take Tamiflu with food.

Do not break or chew the capsules before swallowing.

When to take it

Take one Tamiflu capsule in the morning and one Tamiflu capsule in the evening

Taking your medicine at the same time each day will help you remember when to take the capsules.

How long to take it

Continue taking Tamiflu until your doctor tells you to stop or your course of treatment is complete.

The usual length of treatment is five days.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Otherwise, take it as soon as you remember and then go back to taking it as you would normally.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering your dose, ask your pharmacist for some hints.

In case of an overdose

At present there has been no experience with overdose of Tamiflu. If you or anyone else may have taken more than the recommended dose of Tamiflu, immediately telephone your doctor or National Poisons Information Centre (telephone (03) 474 7000), or go to Accident and Emergency at your nearest hospital. Do this even if there are no signs of discomfort or poisoning.

We would anticipate that an overdose of Tamiflu could cause similar side effects to those that have been reported following recommended doses (see side effects section).

Keep telephone numbers for these places handy.

If you are not sure what to do, contact your doctor or pharmacist.

Tamiflu helps most people with the flu but it may have unwanted side effects in a few people.

These are the more common side effects of Tamiflu. Mostly these are mild.

Taking Tamiflu with food may reduce the potential for some or all of these side effects.
