Antiviral medications like oseltamivir phosphate are commonly prescribed for influenza. While the duration for taking oseltamivir phosphate 75 mg often follows a standard course for treating uncomplicated influenza, the precise length can vary based on factors such as whether it's used for treatment or prevention, as well as the patient’s specific health needs.

Antiviral drugs like oseltamivir are a crucial tool for managing influenza, an illness that requires hospitalization for hundreds of thousands of people annually. When considering treatment, a common question arises: Is there a difference between Tamiflu and Antiflu? Both medications contain the exact same active ingredient, oseltamivir phosphate.

Oral sores, a rare but documented side effect of the flu medication Tamiflu (oseltamivir), can be mistaken for cold sores. The question, 'Can Tamiflu cause cold sores?', requires understanding the difference between a specific drug reaction and a flare-up triggered by the influenza infection itself.

According to the Centers for Disease Control and Prevention (CDC), four FDA-approved antiviral drugs are recommended for treating the flu, including the commonly prescribed Tamiflu. However, in situations of shortages, allergies, or other medical contraindications, patients and healthcare providers may seek to understand what's the closest thing to Tamiflu and what options are available.

Each year, approximately 8% of the U.S. population gets sick from the flu [1.3.4]. If you're wondering, **Can I buy Tamiflu over the counter?**, the answer is no; this effective antiviral medication requires a doctor's prescription [1.2.2].
