What is a common side effect of taking Oseltamivir?

Oseltamivir, an antiviral medication used primarily for the treatment and prevention of influenza, is known to cause several side effects. Nausea is a frequently reported side effect among patients taking this medication. The mechanism behind this side effect is not entirely understood, but it is thought to be related to the drug's effect on the gastrointestinal system.

Patients often experience nausea during the early days of treatment, which can sometimes be alleviated by administering the medication with food. Recognizing this side effect is important for healthcare providers as it can impact patient adherence to the treatment regimen. Understanding the common side effects of medications like Oseltamivir is essential for patient education and managing expectations during therapy. Other side effects such as headache, fatigue, or diarrhea can occur but are not as commonly experienced as nausea in patients taking this medication.
