Can erythromycin eye ointment and tobramycin eye drops be used together?

Under normal circumstances, erythromycin eye ointment and tobramycin eye drops can be used together, as these two medications typically do not interact with each other. The specific analysis is as follows:

Erythromycin eye ointment is a topical antibacterial ophthalmic preparation, primarily composed of vaseline and erythromycin. It is mainly used to treat trachoma, conjunctivitis, blepharitis, and external eye infections. Tobramycin eye drops belong to the aminoglycoside class of antibiotics, with tobramycin as the main active ingredient. They are primarily used to treat localized infections of the external eye and its accessory structures caused by susceptible bacteria.

Both medications are used to treat bacterial infections, and their components generally do not interfere with each other. Therefore, they can usually be used simultaneously. When used together, they can effectively inhibit bacterial protein synthesis, suppress bacterial growth, and eliminate bacteria, thereby accelerating recovery from infection.

During treatment, patients should maintain good eye hygiene and avoid excessive rubbing of the eyes with dirty hands. Staying up late should be avoided, and maintaining a regular, healthy sleep schedule will promote recovery.
