Natamycin is used to treat fungal eye infections. It works by stopping the growth of certain types of fungus.
This medication treats only fungal eye infections. It will not work for other types of eye infections. Unnecessary use or misuse of any drug used to treat infection can lead to its decreased effectiveness.
Use this medication in the affected eye(s) as directed by your doctor.
To apply eye drops, wash hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.
Do not wear contact lenses while you are using this medication. Sterilize contact lenses according to the manufacturer's directions, and check with your doctor before you begin using them again.
Shake the bottle well before using. Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch. Look downward, gently close your eyes, and place one finger at the corner of your eye (near the nose). Apply gentle pressure for 1 to 2 minutes before opening your eyes. This will prevent the medication from draining out. Try not to blink or rub your eye. If directed to use this medication in both eyes, repeat these steps for your other eye. Do not rinse the dropper. Replace the dropper cap after each use.
If you are using another kind of eye medication (such as drops or ointments), wait at least 5 minutes before applying other medications. Use eye drops before eye ointments to allow the drops to enter the eye.
Wait several minutes for your vision to clear before driving or operating machinery.
Use this medication regularly to get the most benefit from it. Continue to use it for the full time prescribed, even if symptoms disappear after a few days. Stopping the medication too early may allow the fungus to continue to grow, which may result in a return of the infection.
This medication is usually prescribed for 2 to 3 weeks or until the infection is cured. Tell your doctor if your condition persists or worsens.
Eye discomfort or irritation may occur. If either of these effects persists or worsens, tell your doctor or pharmacist promptly.
