• if you are allergic (hypersensitive) to oseltamivir or any of the other ingredients of Tamiflu listed in section 6.

Talk to your doctor if this applies to you. Do not take Tamiflu.

Before you take Tamiflu, make sure the prescribing doctor knows

• if you are allergic to other medicines
• if you have problems with your kidneys. If so, your dose may need adjustment
• if you have a severe medical condition, which may require immediate hospitalisation
• if your immune system is not working
• if you have chronic heart disease or respiratory disease.

During treatment with Tamiflu, tell a doctor immediately:

• if you notice changes in behaviour or mood (neuropsychiatric events), especially in children and adolescents). These may be signs of rare but serious side effects.

Tamiflu is not a vaccine: it treats infection, or prevents the flu virus spreading. A vaccine gives you antibodies against the virus. Tamiflu will not change the effectiveness of a flu vaccine, and you might be prescribed both by your doctor.

Tell your doctor or pharmacist if you are taking any other medicines, or have recently taken any. This includes medicines obtained without a prescription. The following medicines are particularly important:

• chlorpropamide (used to treat diabetes)
• methotrexate (used to treat e.g. rheumatoid arthritis)
• phenylbutazone (used to treat pain and inflammation)
• probenecid (used to treat gout)

You must tell your doctor if you are pregnant, if you think you are pregnant or if you are trying to get pregnant so that your doctor can decide if Tamiflu is right for you.

The effects on breast-fed infants are unknown. You must tell your doctor if you are breast-feeding so that your doctor can decide if Tamiflu is right for you.

Ask your doctor or pharmacist for advice before taking this medicine.

Tamiflu has no effect on your ability to drive or use machines.

Tamiflu contains sorbitol.

Sorbitol is a source of fructose. If your doctor has told you that you have an intolerance to some sugars or if you have been diagnosed with hereditary fructose intolerance (HFI), a rare genetic disorder in which a person cannot break down fructose, talk to your doctor before you take or receive this medicine.

Sorbitol may cause gastrointestinal discomfort and mild laxative effect.

10 ml oseltamivir suspension contains 1.7 g of sorbitol.

12.5 ml oseltamivir suspension contains 2.1 g of sorbitol.

Tamiflu contains sodium benzoate.

Sodium benzoate (E211) may increase jaundice (yellowing of the skin and eyes) in newborn babies (up to 4 weeks old).

5 ml oseltamivir suspension contains 2.5 mg of sodium benzoate.

7.5 ml oseltamivir suspension conains 3.75 mg of sodium benzoate.

Do not take a double dose to make up for a forgotten dose.

There are no side effects when you stop Tamiflu. But if Tamiflu is stopped earlier than your doctor told you, the symptoms of flu may come back. Always complete the course that your doctor prescribed.
