How and when should I take Tamiflu (Oseltamivir)?
For the treatment of flu, Tamiflu (Oseltamivir) should be taken twice daily (once in the morning and once in the evening) for five days. Tamiflu (Oseltamivir) can be taken with or without food. As with many medicines, if taken with a light snack, milk, or a meal, the potential for stomach upset may be reduced. You should complete the entire treatment of ten doses, even if you are feeling better. Never share Tamiflu (Oseltamivir) with anyone, even if they have the same symptoms. It is important that you begin your treatment with Tamiflu (Oseltamivir) as soon as possible from the first appearance of your flu symptoms.
