conjunctivitis takes a week to 10 days to go and if its viral it can take a little long to go. antibiotics is the only solution for it rest other drops u can use for reducing ur symptoms to some extent like refresh tears for soothing sensation and mezol eye drops for reducing the redness.

Hello

Mezol contains decongestant Naphazoline and it won't help in infection.I would suggest you to use ciplox eye drop 1 drop each eye 4-6 times a day.
First wash your hand with soap properly and then clean the eye from inside to outside with the help of cotton swab soaked in distilled water each time before putting the eye drop.Avoid Kajal if you are using it.
