Tetracycline is an antibiotic. It is used to treat eye infections caused by bacteria such as conjunctivitis (redness and inflammation of the membranes covering the white part of eyes) and trachoma (an eye infection which causes scarring of the inside of the eyelid and may lead to blindness when left untreated).
It is also used to prevent conjunctivitis that may be contracted by newborns during delivery.
Use Tetracycline exactly as directed by your doctor or according to the instructions on the label. Do not use more or less than instructed by your doctor.
Apply Tetracycline eye ointment in the affected eye(s) exactly as directed by your doctor.
- Wash and dry your hands before applying the ointment.
- With your index finger, pull the lower eyelid down the eye to form a pouch.
- Hold the tube with your other hand and place it as near to your eyelid as possible without touching it. Squeeze a thin strip of ointment (about 1-1.5 cm) into the pouch.
- Gently close your eyes and keep them closed for 1-2 minutes and rotate the eyeball in all directions to enable the spread of the ointment on the entire eye surface.
- Wipe any excess ointment from the eyelids and lashes with a clean tissue. With another clean tissue, wipe the tip of the tube clean.
- Replace and tighten the cap of the tube.
- Wash your hands to remove any medication.
Do not share your eye ointment with anyone else.
When used to prevent conjunctivitis in newborns, it is given as a single application within 1 hour after delivery.
