Your son appears to have a very severe eye infection which is not responding to treatment.He probably has a have a virus eye infection caused by the herpes virus. He does not have an eye allergy so he should not be taking Allergex [an antihistamine] which will make him sleepy and miserable.He needs to be seen by an eye specialist so that he can be correctly diagnosed and treated[including sending a sample of the pus from his eye to the laboratory]This should be done ASAP.Possibly your best move would be to take him to an after hours emergency paediatric clinic.
