What are the possible side effects of oseltamivir (Tamiflu®)?
Tamiflu® has been in use since 1999. The most common side effects are nausea and vomiting which usually happen in the first 2 days of treatment. Taking Tamiflu® with food can reduce the chance of getting these side effects. The FDA now requires that neuraminidase inhibitors have information in the package labeling that warns that people with the flu, mostly children, may be at an increased risk of self-injury and confusion shortly after taking and should be closely monitored for signs of unusual behavior. This precaution was added after the FDA received post marketing reports (mostly from Japan) about persons (primarily among children and adolescents) who had purposefully injured themselves or been delirious while using neuraminidase inhibitors to treat influenza. Most reports were among persons using Tamiflu. The reports appear to be uncommon. For more information, visit the Food & Drug Administration’s MedWatch page.
