1. What Tamiflu is and what it is used for

  • Tamiflu is used in adults, adolescents, children, and infants (including full-term newborn babies) for the treatment of influenza (influenza). It may be used when you have influenza symptoms and it is known that the influenza virus is circulating in the community.
  • Tamiflu may also be prescribed to adults, adolescents, children, and infants older than 1 year of age for prevention of influenza on a case-by-case basis, for example, if you have been in close contact with someone who has influenza.
  • Tamiflu may be prescribed to adults, adolescents, children, and infants (including full-term newborn babies) as prophylactic treatment under exceptional circumstances, for example, during a global influenza outbreak (an influenza pandemic) and when the seasonal influenza vaccine may not provide sufficient protection.

Tamiflu contains oseltamivir, which belongs to a group of medicines known as neuraminidase inhibitors. These medicines prevent the spread of the influenza virus within the body. They help to relieve or prevent symptoms caused by infection with the influenza virus.

Influenza is a viral infection. Signs of influenza often include sudden fever (above 37.8°C), cough, runny or stuffy nose, headache, muscle aches, and extreme tiredness. These symptoms may also be caused by other infections. True influenza infection occurs only during annual outbreaks (epidemics), when influenza viruses are circulating in the population. Outside epidemic periods, influenza-like symptoms are usually due to other illnesses.

2. What you need to know before taking Tamiflu

Do not take Tamiflu

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

If this applies to you, consult your doctor. Do not take Tamiflu.

Warnings and precautions

Before taking Tamiflu, make sure your doctor knows if you:

  • are allergic to other medicines
  • have a kidney disease. If so, your dose may need to be adjusted.
  • have a serious illness requiring immediate hospitalization.
  • have a poorly functioning immune system.
  • have chronic heart or respiratory disease.

During treatment with Tamiflu, contact a doctor immediately if:

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

Tamiflu is not an influenza vaccine

Tamiflu is not a vaccine: it is used to treat infection or prevent the spread of the influenza virus. A vaccine provides antibodies against the virus. Tamiflu does not affect the effectiveness of the influenza vaccine, and your doctor may prescribe both.

Taking Tamiflu with other medicines

Tell your doctor or pharmacist if you are taking, or have recently taken, any other medicines, including those obtained without a prescription.

The following medicines are particularly important:

  • chlorpropamide (used to treat diabetes)
  • methotrexate (used to treat, for example, rheumatoid arthritis)
  • phenylbutazone (used to treat pain and inflammation)
  • probenecid (used to treat gout)

Pregnancy and breastfeeding

Inform your doctor if you are pregnant, think you may be pregnant, or plan to become pregnant, so your doctor can decide whether Tamiflu is suitable for you.

The effects on infants are unknown. Inform your doctor if you are breastfeeding so they can decide whether Tamiflu is appropriate for you.

Consult your doctor or pharmacist before using this medicine.

Driving and using machines

Tamiflu has no effect on your ability to drive or operate machinery.

Tamiflu contains sorbitol

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

Sorbitol may cause gastrointestinal discomfort and a mild laxative effect.

5 ml of oseltamivir suspension contains 0.9 g of sorbitol.

7.5 ml of oseltamivir suspension contains 1.3 g of sorbitol.

10 ml of oseltamivir suspension contains 1.7 g of sorbitol.

12.5 ml of oseltamivir suspension contains 2.1 g of sorbitol.

Tamiflu contains sodium benzoate

Sodium benzoate (E211) may increase the risk of jaundice (yellowing of the skin and eyes) in newborns (up to 4 weeks of age).

5 ml of oseltamivir suspension contains 2.5 mg of sodium benzoate.

7.5 ml of oseltamivir suspension contains 3.75 mg of sodium benzoate.

10 ml of oseltamivir suspension contains 5.0 mg of sodium benzoate.

12.5 ml of oseltamivir suspension contains 6.25 mg of sodium benzoate.

Tamiflu contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per single dose (based on a maximum dose of 75 mg); therefore, it is essentially "sodium-free".

3. How to take Tamiflu

Follow exactly the Tamiflu dosing instructions provided by your doctor. Consult your doctor or pharmacist if you have any questions.

Always use the oral dispenser included in the package, which has markings indicating the dose in milliliters (ml).

Take Tamiflu as soon as possible, ideally within two days after the onset of flu symptoms.

Recommended doses

For the treatment of influenza, take two doses daily. It is generally advisable to take one dose in the morning and one in the evening. It is important to complete the full 5-day course of treatment, even if you start feeling better quickly.

For patients with a weakened immune system, treatment will continue for 10 days.

For the prevention of influenza or after exposure to an infected person, take one dose daily for 10 days. It is best to take this dose each morning with breakfast.

In special situations, such as widespread influenza outbreaks or in patients with a weakened immune system, treatment may continue for up to 6 or 12 weeks.

The recommended dose depends on the patient's body weight. You should use the amount of Tamiflu prescribed by your doctor. Tamiflu oral suspension can be used in individuals who cannot swallow capsules. See instructions below for preparing and administering the dose.

If you take more Tamiflu than you should

Stop taking Tamiflu and consult your doctor or pharmacist immediately.

In many cases of overdose, no adverse effects were reported. When adverse effects were reported, they were similar to those observed with normal doses and listed in section 4.

Overdoses of Tamiflu have been reported more frequently in children than in adults and adolescents. Caution must be exercised when preparing liquid Tamiflu for children and when administering Tamiflu capsules or liquid to children.

If you forget to take Tamiflu

If you stop taking Tamiflu

No adverse effects occur when you stop taking Tamiflu. However, if you stop taking Tamiflu before the time prescribed by your doctor, flu symptoms may return. Always complete the course of treatment prescribed by your doctor.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.

4. Possible adverse effects

Like all medicines, this medicine can cause adverse effects, although not everyone will experience them. Many of these adverse effects may be due to influenza itself.

Since the marketing of oseltamivir, the following serious adverse effects have rarely been reported:

  • Anaphylactic and anaphylactoid reactions: severe allergic reactions, with swelling of the face and skin, itchy rash, low blood pressure, and difficulty breathing.
  • Hepatic disorders (fulminant hepatitis, liver function disorders, and jaundice): yellowing of the skin and whites of the eyes, change in stool color, changes in behavior.
  • Angioneurotic edema: sudden, severe swelling of the skin, mainly around the head and neck area, including eyes and tongue, with difficulty breathing.
  • Stevens-Johnson syndrome and toxic epidermal necrolysis: a severe, potentially life-threatening allergic reaction, with serious inflammation of the outer and possibly inner skin layers, initially presenting with fever, sore throat, fatigue, skin rash, blistering, peeling, and large areas of skin shedding, possible breathing difficulties, and low blood pressure.
  • Gastrointestinal hemorrhage: prolonged bleeding from the large intestine or vomiting blood.
  • Neuropsychiatric disorders, as described below.

If you notice any of these symptoms, seek medical help immediately.

The most frequently reported adverse effects (very common and common) for Tamiflu are malaise or discomfort (nausea, vomiting), stomach pain, stomach discomfort, headache, and pain. These adverse effects usually occur after the first dose of the medicine and generally resolve during the course of treatment. The frequency of these effects is reduced if the medicine is taken with food.

Rare but serious adverse effects: seek medical help immediately

(These may affect up to 1 in 1,000 people)

Rare adverse effects have been reported during treatment with Tamiflu, including:

  • seizures and delirium, including altered levels of consciousness
  • confusion, abnormal behavior
  • delirious disorders, hallucinations, agitation, anxiety, nightmares

Instructions for the user

Do not use if the packaging is damaged, or if any of the supplied materials are missing or damaged.

  • Contact your doctor or pharmacist if the dispenser is missing or damaged (e.g., the dose marking is no longer clearly visible or it is difficult to handle). They will advise you on how to continue taking your medication.

Use and clean the oral dispenser as described in these instructions to avoid any possible contamination.

Wash your hands before and after using the product.

There are two steps to take the oral suspension.

Step 1 Prepare a new bottle of medicine

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

Step 2 Measure and administer the correct dose

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

Step 1 Prepare a new bottle of medicine

You will need:

? The bottle containing Tamiflu powder (in the medicine package), with the bottle cap attached
? A plastic measuring cup (in the medicine package)
? The plastic bottle adapter (in the medicine package)
? Water

? Tap the bottle to loosen the powder
Gently tap the closed bottle several times to loosen the powder

? Use the cup to measure 55 mL of water
The measuring cup included in the package has a marked line to show you the exact amount.
Fill it with water up to the indicated level.

? Add water, close and shake
Pour all the water from the cup into the bottle, over the powder.
Always use 55 mL of water, regardless of the dose required.
Put the cap on the bottle. Shake the bottle well for 15 seconds.

? Press in the adapter
Open the bottle and firmly press the bottle adapter 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 ensure that the adapter fits securely in the bottle in the correct position.

You now have a prepared bottle of Tamiflu oral suspension ready for measuring and administering a dose. You will not need to prepare it again until you start a new bottle.

Step 2: Measure and administer the correct dose

You will need:

? A prepared bottle of Tamiflu oral suspension
? Depending on the required dose, you will need either the 3 mL oral dispenser (orange plunger, 0.1 mL graduations) or the 10 mL oral dispenser (transparent plunger, 0.5 mL graduations) included in the package.
? For doses from 1.0 mL to 3.0 mL, use the 3 mL oral dispenser. For doses above 3.0 mL up to 10 mL, use the 10 mL oral dispenser.

Always use the oral dispenser supplied in the package to measure the correct dose.

Two syringes with labels: the first is 3 ml with an orange plunger, the second is 10 ml with a transparent plunger and milliliter markings

? Shake the bottle
Ensure the bottle is tightly closed, then shake the Tamiflu oral suspension bottle.
Always shake well before use.

? Prepare the oral dispenser
Depending on the required dose, use either the 3 mL oral dispenser (orange plunger) or the 10 mL oral dispenser (transparent plunger) provided in the package.
Press the plunger fully down to the tip of the dispenser.

Ensure that all the medicine has been swallowed.

After taking the medicine, the person may drink fluids or eat food.

? Close the bottle and store safely
Replace the cap on the bottle. Keep out of sight and reach of children.

Store the medicine below 25 °C for up to 10 days. See section 5. Storage of Tamiflu, in this leaflet.

  • Clean the dispenser
    Immediately after administration, separate the parts of the dispenser and wash both parts under tap water until all residue is removed. If tap water is not available, rinse with clean water (e.g., distilled water).

Do not sterilize or boil the oral dispenser, or place it in boiling water, to avoid damage. Allow the dispenser to air-dry before next use.

For storage, keep the dispenser dry and protected from direct sunlight.

Do not discard the oral dispenser, as it must be used multiple times. Only after final use, dispose of the oral dispenser according to local regulations.
