Taking this antiviral medication does not cause drowsiness. If drowsiness occurs, it is likely attributable to the common cold itself. You may consider adding other cold-relief medications; indeed, most over-the-counter cold medications have sedative effects. Ensuring adequate sleep and sufficient rest during a cold also promotes recovery.
