1. Why am I using Tamiflu?

Tamiflu contains the active ingredient oseltamivir. Tamiflu is an antiviral medicine.

Tamiflu is used for treatment and prevention of influenza (an infection caused by influenza virus). It has no effect on the common cold or other respiratory virus infections.

Tamiflu attacks the influenza virus and prevents it from spreading inside your body. Give Tamiflu suspension as directed by your child’s doctor or pharmacist.

The usual dose of Tamiflu is one dose taken TWICE a day. The dose may vary depending on your child’s weight.

Tamiflu is absorbed to the key sites of influenza infection and treats the cause. Taking Tamiflu can prevent you from catching the flu, or if you have already caught the flu, taking Tamiflu means you feel better faster.

You will also be less likely to develop complications of influenza, such as bronchitis, pneumonia, sinusitis and ear infection. Typical symptoms of influenza include fever, headache, muscle aches, sore throat, cough and extreme tiredness.

Tamiflu will help reduce the chances of you passing the flu onto someone else.

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

Tamiflu is not addictive.

Ask your doctor about having the influenza vaccination.

Vaccination every year is the best way to prevent influenza.

2. What should I know before I use Tamiflu?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with Tamiflu and affect how 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.

Safety and effectiveness in children under 1 year of age have not been established.

How to take it

Shake the suspension well every time you use it to ensure you get the right dose. The powder in the suspension may settle during storage.

Tamiflu can be taken with or without food. However, you may find Tamiflu is easier on your stomach when taken with food.

Your pharmacist may have prepared the oral suspension for you when you collected your prescription. However, if they have not done this then you can do it easily yourself. You only need to prepare the suspension once, at the beginning of your course.

After that, all you need to do is shake the suspension well and draw up the appropriate recommended dose.

Tap the closed bottle gently several times to loosen the powder.

  • Measure 55mL of water by filling the measuring cup to the indicated level (measuring cup included in the box). You should always use 55mL of water, irrespective of the recommended dose you are taking. It is best to use bottled water or boiled water that has been cooled.
  • Add all 55mL of water into the bottle, recap the bottle and shake the closed bottle well for 15 seconds. The powder plus 55mL of water will make a total volume of 65mL.
  • Remove the cap and push the bottle adapter into the neck of the bottle.
  • Place the cap tightly over the top of the bottle, which now includes the bottle adapter. This will make sure that the bottle adapter fits in the bottle in the right position.

    • How to measure and give a dose of oral suspension

  • Shake the closed bottle of Tamiflu oral suspension well before use.
  • Take the dispenser (see Figure 2) and push the plunger completely down toward the tip of the dispenser.
  • Remove the cap from the bottle of oral suspension.
  • Insert the bottle adaptor into the neck of the bottle (see Figure 3).
  • Insert the tip of the dispenser into the bottle adapter.
  • Turn the entire unit (bottle and dispenser) upside down (see Figure 4).
  • Slowly pull out the plunger to the graduation marks in mL which your doctor or pharmacist has instructed you to take.
  • Turn the entire unit upright.
  • Slowly remove the dispenser from the bottle.
  • Push the suspension directly into the mouth by pushing down the plunger of the dispenser. Swallow the medicine. You may drink and eat something after taking the medicine.
  • Immediately after administration, take the dispenser apart and rinse both parts of the dispenser under running tap water. Allow dispenser to air dry before next use.
  • Do not boil the oral dispenser to avoid damage of the dispenser.
  • Contact your doctor or pharmacist if the dispenser is lost. If the dispenser is damaged, do not use it, contact your doctor or pharmacist and they will advise you on how to continue to take your medication.

    • Each bottle of Tamiflu 6mg/mL oral suspension contains 390mg of oseltamivir in a final volume of 65mL suspension. Depending on the dose your doctor has prescribed for you or your child, you may have suspension left over. Discard any unused suspension once you have completed your treatment course.

    When to take it

    Treatment with Tamiflu oral suspension should be started as soon as possible, but no later than 48 hours after the first symptoms of influenza.

    For influenza treatment, Tamiflu oral suspension should be taken in the morning and in the evening.

    For influenza prevention, Tamiflu oral suspension should be taken once a day.

    If you have kidney problems, you doctor may tell you to take Tamiflu less often.

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

    How long to take it

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

    If you have a weakened immune system, your doctor may tell you to take a longer course.

    If you forget to use Tamiflu

    Tamiflu should be used regularly at the same time each day.

    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.
    • Do not take a double dose to make up for the dose you missed.

    If you use too much Tamiflu

    If you think that you have used too much Tamiflu, you may need urgent medical attention.
