1. What Tamiflu is and what it is used for

  • Tamiflu is used for adults, adolescents, children and infants (including full-term newborn babies) for treating flu (influenza). It can be used when you have flu symptoms, and the flu virus is known to be going round in your community.
  • Tamiflu can also be prescribed for adults, adolescents, children and infants above 1 year of age for preventing flu, on a case-by-case basis – for instance, if you have been in contact with someone who has flu.
  • Tamiflu may be prescribed for adults, adolescents, children and infants (including full-term newborn babies) as preventive treatment in exceptional circumstances – for example, if there is a global epidemic of flu (a flu pandemic) and the seasonal flu vaccine may not provide sufficient protection.

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.

2. What you need to know before you take Tamiflu

Do not take Tamiflu:

  • 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.

Warnings and precautions:

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 flu vaccine

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.

Other medicines and Tamiflu

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)

Pregnancy and breast-feeding

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.

Driving and using machines

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

Tamiflu contains fructose

Before you take Tamiflu, make sure your prescribing doctor knows if you have hereditary fructose intolerance. This medicine contains sorbitol, which is a form of fructose.

Sorbitol can have a mild laxative effect.

3. How to take Tamiflu

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.

The recommended doses

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 preventing flu or after being exposed to an infected person, take one dose daily for 10 days. It is best to take this in the mornings with breakfast.

In special situations, such as widespread flu, or for patients with a weak immune system, treatment will continue for up to 6 or 12 weeks.

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.

Instructions for the user

There are two stages to taking Tamiflu oral suspension.

Stage 1 Prepare a new bottle of the medicine

Your pharmacist may have prepared the medicine for you when you collected your prescription. If not, you can do it easily yourself. See the first set of instructions. You only need to do this once, at the beginning of your course.

Stage 2 Measure and give the correct dose

Shake the suspension well and draw the appropriate recommended dose into the dispenser. See the second set of instructions. You will need to do this every time you need a dose.

Stage 1: Prepare a new bottle of the medicine

You will need:

  • The bottle, containing Tamiflu powder (in the medicine pack)
  • The bottle cap (in the medicine pack)
  • A plastic measuring jug (in the medicine pack)
  • The plastic bottle adapter (in the medicine pack)
  • Water
  • Tap the bottle to loosen the powder
    Tap the closed bottle gently several times to loosen the powder.
  • Use the jug to measure 55 ml of water
    The measuring jug in the pack has a line marked to show you an exact amount.
    Fill it with water to the indicated level.
  • Add all the water, close and shake
    Pour all of the water from the jug into the bottle, onto the powder.
    Always use 55 ml of water, whatever the dose you need.
    Put the cap back on the bottle. Shake the bottle well for 15 seconds.
  • Press in the adapter
    Open the bottle and press the bottle adapter hard into the neck of the bottle.
  • Close the bottle again
    Screw the cap tightly onto the top of the bottle, which now includes the adapter.
    This will make sure that the bottle adapter fits in the bottle in the right position.

You now have a bottle of Tamiflu oral suspension ready to measure out a dose. You will not need to prepare it again unless you start a new bottle.

Stage 2: Measure and give the correct dose

You will need:

  • A bottle of prepared Tamiflu oral suspension
  • Depending on the required dose you will need the 3 ml oral dispenser (yellow plunger, 0.1 ml graduation) or the 10 ml oral dispenser (white plunger 0.5 ml graduation) from the medicine pack.
  • For doses from 1.0 ml to 3.0 ml, the 3 ml oral dispenser should be used. For doses above 3.0 ml to 10 ml, 10 ml oral dispenser should be used.

Always use the oral dispenser provided with your medicine to measure a correct dose.

  • Shake the bottle
    Check the cap is secure, and then shake the bottle of Tamiflu oral suspension.
    Always shake well before use.
  • Prepare the oral dispenser
    Depending on the required dose, use the 3 ml dispenser (yellow plunger) or the 10 ml oral dispenser (white plunger) provided in the pack.
    Push the plunger completely down toward the tip of the dispenser.
  • Fill the dispenser with the correct dose
    Unscrew the cap from the bottle.
    Push the tip of the dispenser into the bottle adapter.
    Then turn the whole unit upside down (bottle and dispenser together).

Slowly pull out the plunger to draw medicine into the dispenser.

Stop at the mark that shows the dose you need.

Turn the whole unit upright.

Remove the dispenser from the bottle.

  • Give the medicine into the mouth
    Deliver the suspension directly into the mouth by pushing down the plunger of the dispenser.
    Make sure the medicine is swallowed.
    You may drink and eat something after taking the medicine.
