Tamiflu (oseltamivir phosphate) Dosage and Side Effects

TAMIFLU is a prescription medication (a viral neuraminidase inhibitor) used to treat or prevent the onset of flu.

Tamiflu Dosage

TAMIFLU is not a substitute for the flu shot. If you are at high risk of developing complications, you should continue to get your flu shot as recommended by your doctor. You might be surprised to find that you are still susceptible to flu even though you got your annual flu shot.

Treatment with TAMIFLU should begin no more than two days after flu symptoms have started to appear. Typical symptoms of flu include sudden onset of fever, headache, tiredness, muscular weakness, runny or stuffy nose, sore throat and cough.

Overdose:

In case of overdose, contact a healthcare practitioner, hospital emergency department or regional poison control centre, even if there are no symptoms.

Missed dose:

If you forget to take a dose of TAMIFLU take it as soon as possible, then just carry on with the regular times you take your medication. Do not take double the amount if you miss one dose.

If you have missed several doses, inform your doctor and follow the advice given to you. Do not change your dose of TAMIFLU unless instructed to do so by your doctor.

Side Effects

Unwanted effects are possible with all medicines. Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking TAMIFLU.

TAMIFLU is generally well tolerated. The most common/possible unwanted effects are:

  • nausea
  • vomiting
  • abdominal pain
  • headache

Taking TAMIFLU with food may reduce possible stomach upset.

Severe skin and hypersensitivity reactions have been reported since the marketing of TAMIFLU. Symptoms of skin reactions include flushing, rash, itching or swelling. Symptoms of hypersensitivity reactions include dizziness or breathing problems.

Cases of liver toxicity have also been reported, symptoms of which include, yellowing of skin or eyes and dark urine.

People with the flu, particularly children and adolescents, may be at an increased risk of seizures, confusion, delirium, hallucinations, agitation, anxiety or other abnormal behaviour early during their illness. These events may occur shortly after beginning TAMIFLU or may occur when flu is not treated. These events are uncommon but may result in self-injury to the patient, sometimes fatal. Therefore, patients should be observed for signs of unusual behaviour and a healthcare professional should be contacted immediately if the patient shows any signs of unusual behaviour.

Some unwanted effects may go away during treatment as your body adjusts to the medicine. If you are concerned about these or any other unexpected effects while on TAMIFLU, talk with your doctor or pharmacist.

This is not a complete list of side effects. For any unexpected effects while taking TAMIFLU, contact your doctor or pharmacist.

Warnings and Precautions

BEFORE you use TAMIFLU talk to your doctor or pharmacist if:

  • you ever had a bad reaction to oseltamivir phosphate (TAMIFLU) or any of the inactive ingredients
  • you have hereditary fructose intolerance, as the TAMIFLU oral suspension contains sorbitol and you should not use the suspension if you have this condition
  • you are allergic to other medicines, food and dyes
  • you are taking any other medicines, including those not prescribed by your doctor
  • you have any type of kidney disease
  • you are pregnant, plan on becoming pregnant, breast-feeding or planning to breast-feed.

This information will help your doctor and you decide whether you should use TAMIFLU and what extra care may need to be taken while you are on the medicine.
