Hello. Eye twitching is very common and usually harmless. It is likely triggered by the physical stress, fatigue, or mild dehydration associated with your body fighting acute pharyngitis, rather than the infection itself. There is no specific medication needed to treat temporary eye twitching. Instead, the best approach is supportive care: get plenty of rest, stay well-hydrated, limit caffeine, and try applying a warm compress to your eye. Please review your current pharyngitis medications with your doctor to ensure it is not a rare side effect. If the twitching worsens, spreads, or persists for more than a few weeks, please seek a medical evaluation.
