1. Antibiotic cannot cure allergy
. You will need to use some anti-allergic drug like Olapatadine (like Pataday once daily in morning or IF2 twice a day)
2. Frequent rubbing of eyes can cause recurrent stye in both eyes. If there is any other lid pathology also this can happen.
Use good anti-allergic drugs, a good lubricating drop (like Refresh
tears 3-4 times/day). Avoid rubbing your eyes. If you have irritation wash with cold water or place a cube of ice over your closed eyes lightly for half a minute.
Also consider taking some omega 3 fatty acid supplementation (like seven seas tablet once daily)
