What happens when you take an antiviral and you don't have a virus?

If you take an antiviral medication without having a viral infection, it typically has no beneficial effect and may lead to unnecessary side effects. Antivirals are specifically designed to target and inhibit viral replication, so their efficacy relies on the presence of a virus. Additionally, misuse of antiviral medications can contribute to resistance, making them less effective for those who actually need them in the future. Always consult a healthcare professional before taking any medication.
