Gentak is used to treat external eye infections, including bacterial conjunctivitis (pink eye) and other superficial ocular infections caused by bacteria susceptible to gentamicin. It may also be used for prevention of infection after minor eye surgery or procedures.
Gentak contains gentamicin, an aminoglycoside antibiotic that works by inhibiting bacterial protein synthesis. It is bactericidal, meaning it actively kills bacteria rather than just preventing their growth, targeting the specific bacteria causing the infection.
Gentak is for ophthalmic use only and should not be injected into the eye. Patients should wash hands before and after use, avoid touching the dropper tip to prevent contamination, and complete the full course of treatment as prescribed. Contact lens wearers should consult their doctor, and any signs of allergic reaction or worsening symptoms should be reported to a healthcare provider immediately.
