Dosage & Administration

Shake well immediately before use. For Middle Ear Infection: Instill 2-4 drops in the affected ear three to four times a day and at night, or more frequently if required. The suspension should be warmed by holding the bottle in the hand for one or two minutes to avoid dizziness, which may result from the instillation of a cold suspension. The patient should lie with the affected ear upward, and then the drops should be instilled. The tragus should then be pumped 5 times by pushing inward to facilitate penetration of the drops into the middle ear. This position should be maintained for two minutes. Repeat, if necessary, for the opposite ear. Discard unused portion after therapy is completed. For 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. The suspension should be warmed by holding the bottle in the hand for one or two minutes to avoid dizziness, which may result from the instillation of a cold suspension. The patient should lie with the affected ear upward, and then the drops should be instilled. This position should be maintained for two minutes to facilitate penetration of the drops into the ear canal. Repeat, if necessary, for the opposite ear. Discard unused portion after therapy is completed.


Precautions

Gentabac® HC Ear Drops should be discontinued at the first appearance of any sign of local or general hypersensitivity. Long-term continuous therapy should be avoided. Prolonged use may result in overgrowth of non-susceptible organisms, including fungi. If an infection is not improved after one week, cultures and susceptibility tests should be performed to verify the identity of the organism and to determine what alternative therapy should be installed. In severe infections, Gentabac® HC Ear Drops should be supplemented with appropriate systemic antibiotic treatment.
