Tamiflu contains oseltamivir, which belongs to a group of medicines named neuraminidase inhibitors.
These medicines prevent the flu virus from spreading inside the body. They help to ease or prevent the symptoms of the flu virus infection.
Influenza, usually called flu, is an infection caused by a virus. The signs of flu often include a sudden fever (more than 37.8 °C), cough, runny or stuffy nose, headaches, muscle aches and extreme tiredness. These symptoms can also be caused by other infections. True influenza infection only occurs during annual outbreaks (epidemics) when flu viruses are spreading in the local community. Outside epidemic periods, flu-like symptoms are usually caused by a different type of illness.
Talk to your doctor if this applies to you. Do not take Tamiflu.
Before you take Tamiflu, make sure the prescribing doctor knows
During treatment with Tamiflu, tell a doctor immediately:
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:
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.
5 ml oseltamivir suspension contains 0.9 g of sorbitol.
7.5 ml oseltamivir suspension contains 1.3 g of sorbitol.
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.
10 ml oseltamivir suspension contains 5.0 mg of sodium benzoate.
12.5 ml oseltamivir suspension contains 6.25 mg of sodium benzoate.
This medicine contains less than 1 mmol sodium (23 mg) per single dose (based on a maximum dose of 75 mg), that is to say essentially ‘sodium-free’.
Take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Always use the oral dispenser that is provided in the box and has markings indicating the dose in millilitres (ml).
Take Tamiflu as soon as possible, ideally within two days of the flu symptoms starting.
For treating flu, take two doses daily. It is usually convenient to take one dose in the morning and one in the evening. It is important to complete the whole 5-day course, even if you start to feel better quickly.
For patients with a weak immune system, treatment will continue for 10 days.

The recommended dose is based on the patient’s body weight. You must use the amount of Tamiflu prescribed by the doctor. The oral suspension can be used by people who find it hard to take capsules. See the instructions overleaf to make up and give a dose.
