How is conjunctivitis treated?
Bacteria
Conjunctivitis caused by bacteria is treated with antibiotics prescribed by your doctor. The antibiotic can be given as eye drops, ointments, or pills. Eye drops or ointments may need to be applied to the inside of the eyelid three to four times a day for five to seven days. It may be difficult to apply ointment inside of a child's eye, but if the ointment gets as far as the eyelashes, it will most likely melt and enter the eye. Pills may need to be taken for several days. The infection should improve within a week. Take the medicine as instructed by your doctor, even if the symptoms go away.
Virus
Medicine cannot treat conjunctivitis caused by a virus. This type of conjunctivitis often results from a common cold. Just as a cold must run its course, so must this form of conjunctivitis, which will last from 4 to 7 days. You may, however, help relieve symptoms by applying a cold compress on closed eyes.
Irritating substance
To treat this type of conjunctivitis, use warm water for five minutes to wash the irritating substance from the eye. You should also avoid further exposure to the irritating substances. Your eyes should begin to improve within four hours after washing away the substance. If they do not, call your doctor.
