Conjunctivitis

[Sausagenbacon]

I'm so fed up. I have conjunctivitis in one eye 2 weeks ago. Had eyedrops from the pharmacist. It cleared up. And now it's suddenly flared up again. In the same eye.
I still have the eyedrops in the fridge, would it be OK to use them again? Also, is it worth going to the doctors with, or should I try the pharmacist for something different? I'm using chloramphenicol

It’s fine to use after being open a couple of weeks. It would be worth phoning the Drs but keep using them until you manage to get an appointment then cancel if it clears up?

”Store in a refrigerator at a temperature between 2°C and 8°C. Protect from light. Discard the bottle 28 days after opening, even if there is solution remaining. Do not use Chloramphenicol after the expiry date which is stated on the carton “
