Does anyone know if can get an over the counter treatment for conjunctivitis for my 4 month old? Its the 3d time he's had it and I cant find the blasted drops the Dr prescribed him last time. It's mild at the moment, but in the past, if I didn't catch it early, it got worse. I dont want to have to take him to the GP unless I have to (and its Sunday today) and was wondering if I could use Brolene or similar to treat it quickly and nip it in the bud. Its just in the one eye at the moment. Any advice gratefully received!
