If you have known allergies and having swelling of the eyelids or conjunctivitis
, you must use an antihistamine eye drop rather than strong antibacterials.
You can either olopatadine
eye drops 2 drops per eye up to three times daily AND take an antihistamine tablet cetirizine
10mg once daily upto 3 days to get the soft tissue
If these do not work or you develop irritation, stop using the eye drops and get it checked by an ophthalmologist.
