Hello,
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 swelling down.
If these do not work or you develop irritation, stop using the eye drops and get it checked by an ophthalmologist.
Thanks.
