Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
This combination medication is used to treat bacterial infections of the eye or outer ear that include swelling (inflammation). Gentamicin is an antibiotic that works by stopping the growth of bacteria. Betamethasone is a steroid that helps to decrease the swelling, redness, and itching.
This medication treats only bacterial infections. It will not work for other types of eye/ear infections and may worsen them (such as infections caused by viruses, fungi). Using any antibiotic when it is not needed can cause it to not work for future infections.
How To Use
Read the Patient Information Leaflet provided by your pharmacist. If you have any questions, consult your doctor or pharmacist.
Wash your hands first before using this product. To avoid contamination, do not touch the dropper tip or let it touch your ear/eye or any other surface.
EYE: Do not wear contact lenses while you are using this medicine. Sterilize contact lenses according to manufacturer's directions, and check with your doctor before you begin using them again.
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 1 drop into the pouch, usually 3 to 4 times daily or as directed by your doctor. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of your eye (near the nose) and apply gentle pressure. This will prevent the medication from draining out. Try not to blink and do not rub your eye. Repeat these steps if your dose is for more than 1 drop or for your other eye if so directed.
If you are using another kind of eye medication (e.g., drops or ointments), wait at least 5 to 10 minutes before applying other medications. Use eye drops before eye ointments to allow the drops to enter the eye.
EAR: First, clean and dry the outer ear. To make sure that the right amount of medication is given, and to avoid touching the ear with the dropper, have another person insert the drops if possible. To lower the risk of dizziness, hold the container in your hand for a few minutes to warm it.
Lie on your side or tilt the affected ear upward. Hold the dropper directly over the ear, and place the prescribed number of drops into the ear canal, usually 3 to 4 times daily or as directed by your doctor. To help the drops roll into the ear of an adult, hold the earlobe up and back. In children, hold the earlobe down and back. Keep the head tilted for about 2 minutes, or insert a soft cotton plug if so directed. Your doctor may direct you to give this medication in another way by placing a cotton wick in the ear canal and keeping it moist throughout the day as directed. The wick should be replaced at least once a day. Repeat for the other ear if so directed.
Do not rinse the dropper. Replace the cap after use.
Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. Continue to use this medication for the full time prescribed, even if symptoms disappear after a few days. Stopping the medication too soon may allow bacteria to continue to grow, which may result in a return of the infection.
Tell your doctor if your condition does not improve in 2 days, persists (longer than 10 days if used in the eye, longer than 5 to 7 days if used in the ear), or worsens.
