Conjunctivitis generally does not require intravenous treatment; it is mainly treated according to the cause, with local administration of medication being the primary approach. Systemic medication may be required when necessary. Eye drops are the most basic method of administering medication for conjunctivitis. Eye ointment can also be applied to the eyes; since it remains in the conjunctival sac for a longer duration, it is advisable to use it before bedtime. When there is a lot of secretion in the conjunctival sac, a non-irritating rinse solution can be used to wash the conjunctival sac. In severe cases of conjunctivitis, such as gonococcal conjunctivitis and chlamydial conjunctivitis, systemic antibiotics or sulfa drugs are needed in addition to local treatment.
