Other facts about Tamiflu:

Tamiflu is available as 75mg capsules and as a 12mg/ml tutti-frutti flavored Oral Suspension for children who can't swallow pills


some parents warn that the Oral Suspension is not a very good tasting medicine, so you might add extra flavoring, especially if your child does not take medicine easily

Dosage of Tamiflu::
Treatment of Flu (all twice a day for 5 days)
