What adverse effect did Janine experience from Tamiflu?

• A. Nausea
• B. Severe diarrhea
• C. Dizziness
• D. Chest pain

Answer: (B)

Tamiflu, also known as oseltamivir, is an antiviral medication used to treat influenza. Although common side effects of Tamiflu include nausea and dizziness, one of the more significant adverse effects can be gastrointestinal issues, including severe diarrhea. This symptom can occur due to the medication's impact on the gastrointestinal tract, leading to an imbalance or irritation in the digestive system, resulting in more severe symptoms than just mild discomfort.

While nausea and dizziness can be side effects, they typically are not as severe or serious as diarrhea can become, particularly if it leads to dehydration or discomfort. Chest pain does not commonly relate to the effects of this medication. Therefore, severe diarrhea stands out as a notable adverse effect that can significantly impact a patient's health and comfort while on this medication.
