What are common adverse effects associated with oseltamivir?

Oseltamivir, an antiviral medication used primarily for treating influenza, is associated with a range of potential adverse effects. Among these, nausea and vomiting are often reported as common side effects. These gastrointestinal symptoms can occur due to the way the body processes the medication, and while they can be uncomfortable, they are typically transient and manageable.

Seizures, while not one of the most commonly reported effects, have been documented in rare cases, especially in pediatric patients or those with predisposing factors. However, they are not considered standard adverse effects in the general population.

The other options list adverse effects that are less commonly associated with oseltamivir. Hepatic failure and arrhythmias are not typical reactions linked to this antiviral treatment. Rash and anaphylaxis also do occur but are not commonly seen with oseltamivir; these more severe allergies fall into a rarer category of reactions. Lastly, headache and dizziness, while they can occur, are less frequently highlighted as the primary side effects compared to nausea and vomiting.

Thus, the presence of nausea and vomiting, complemented by the possibility of seizures, positions the first choice as the most accurate representation of common adverse effects associated with oseltamivir use.
