Tamiflu has a number of side effects, which are detailed below:
The most frequently seen side effects of Tamiflu are feeling sick or vomiting. Usually these symptoms are not severe, and they occur most often within the first 2 days of treatment. Taking Tamiflu with food or milk may be helpful in reducing the risk of getting these side effects.
If you develop an allergic reaction or severe rash, stop taking Tamiflu and contact your doctor.
People who have the flu virus, in particularly children and teenagers, may be at an increased risk of seizures, confusion, or unusual behavior early during their illness.
Events such as these events can occur shortly after beginning Tamiflu. They may occur when the patient is not treated with Tamiflu.
In any event, these occurrences are uncommon but may result in accidental injury to the patient. Therefore, it is adviseable to observe patients for signs of unusual behavior and a doctor should be contacted immediately if the patient shows signs behaving abnormally.
If you notice any side effects not mentioned here, mention them nevertheless to your doctor and ask his advice.
