Always consult your doctor or pharmacist before taking gentamicin eye & ear drops.
Never use this medication for a longer period of time than you have been instructed to by your doctor or in smaller/larger doses.
You may drive or operate machinery while using gentamicin eye & ear drops as long as the vision is clear.
Indications and Usage
Gentamicin eye & ear drops are indicated in adults and children for both the treatment of superficial eye and ear infections caused by organisms sensitive to gentamicin, and for prophylaxis against infection in trauma of the eye or ear.
Do not use gentamicin eye & ear drops if:
- You are allergic to gentamicin or other ingredients;
- You have a perforated eardrum;
- You are wearing contact lenses;
- You suffer from myasthenia gravis or a related condition.
Use gentamicin eye & ear drops during pregnancy or breastfeeding only if it is deemed essential by your doctor. Consult your doctor or healthcare professional before using gentamicin eye & ear drops.
Administration and Dosage
Refer to your doctor or pharmacist for guidelines on dosage. Do not exceed what they advise. The usual dose is 1-2 drops in the eye every four hours, or 2-4 drops in the ear 3-4 times daily.
Potential interactions include cephalosporins, amphotericin, cisplatin, cyclosporine, diuretic medicines, and curare-type muscle relaxants. Consult your doctor about any medications you are taking before you begin treatment with gentamicin eye & ear drops.
Potent diuretics such as ethacrynic acid and furosemide are believed to enhance risks of ototoxicity. Drugs like amphotericin B, cisplatin, cyclosporine, and cephalosporins are potential enhancers of nephrotoxicity.
Using nephrotoxic or ototoxic drugs at the same time as gentamicin should be avoided unless suggested by your doctor, pharmacist, or health care specialist.
Neuromuscular blockade and respiratory paralysis have been reported in patients from the administration of aminoglycosides, and in patients who have received muscle relaxants during anesthesia.
If you accidentally exceed your dose, tell your doctor, pharmacist, or healthcare specialist to avoid undesired effects. However, the oral ingestion of the contents of one bottle is unlikely to cause any significant adverse reactions.
Long-term treatment should be avoided as it may lead to skin sensitization and the emergence of resistant organisms. Cross sensitivity with other aminoglycoside antibiotics may occur.
For more serious infections, the use of gentamicin should be supplemented with appropriate systemic antibiotic treatment.
If given systemically or applied topically to open wounds or damaged skin gentamicin may cause irreversible partial or total deafness. This effect is dose-related and is enhanced by renal and/or hepatic problems.
The direct contact of gentamicin with the middle and inner ear could cause irreversible toxic effects. Seek emergency medical attention if you find yourself in this kind of situation.
Serious adverse reactions including neurotoxicity, ototoxicity, and nephrotoxicity have occurred in patients receiving systemic gentamicin therapy. Caution is always suggested if using systemic aminoglycosides at the same time.
