Table of contents:

Okacin is an antibiotic used to treat eye infections. It is commonly used for the diagnosis or treatment of bacterial infection, bacterial growth, and burns.

Okacin contains lomefloxacin hydrochloride. It works by inhibiting two enzymes called DNA gyrase and topoisomerase IV that are required for bacterial growth and reproduction. By inhibiting these enzymes, lomefloxacin hydrochloride interferes with bacterial DNA replication, preventing bacteria from multiplying and allowing the body's immune system to clear the infection.

Use and Dosage

Okacin used as eye drops applied topically. Based on the information found across multiple sources, here are the instructions for using Okacin drops:

  1. Wash your hands before using Okacin eye drops.
  2. Gently pull down the lower lid of your eye to form a "pouch".
  3. Tilt your head back and look upward.
  4. Hold the bottle upright and squeeze one or two drops into the lower eyelid pouch.
  5. Close your eyes and press your fingertip at the inner corner of the eye and roll the eyeball, which spreads the drops in the eye.
  6. Use Okacin eye drops as directed by your doctor, usually 2 to 4 times per day until symptoms improve.

After using the drops, wait at least five minutes before opening your eyes to allow the medication to absorb. Avoid touching the droplets with your fingers or allowing the tip of the bottle to touch your eye or surrounding areas.
