Gentamicin is an aminoglycoside antibiotic and has a bactericidal action against many Gram-negative and some strains of Gram-positive bacteria. After actively transporting across the bacterial cell membrane, Gentamicin binds to a specific receptor protein on the 30S subunit of bacterial ribosomes, and interferes with protein synthesis. Hydrocortisone depresses formation, release, and activity of endogenous mediators of inflammation as well as modifying immune response.

Middle Ear Infection:

Ear Canal Infection:

• Instill 2-4 drops in the affected ear three to four times a day and at night, or more frequently if required

Use in Pregnancy: Unsafe during pregnancy. There is definite evidence of risk to the developing baby.

Precautions:

• Discontinue at the first appearance of any sign of local or general hypersensitivity.
• Long-term continuous therapy should be avoided (may cause overgrowth of non-susceptible organisms).
• If no improvement after one week, cultures and susceptibility tests should be performed.
• In severe infections, supplement with appropriate systemic antibiotic treatment.

Overdose: Overdose is unlikely when used as directed. Excessive use may cause ear irritation.
