Hi, my 2 year old son has been diagnosed with pink eye. He has had it once in the past and the doctor prescribed him antibiotic eye drops, this time however he has prescribed just regular over the counter eye drops. Will his pink eye go away with just the regular drops or will he eventually need the other drops? He is also on an antibiotic for an ear infection, not sure if this is why he wasn't prescribed the antibiotic eye drops. Thank you!
