Factive generically known as Gemifloxacin mesylate is a fluoroquinolone antibiotic medication used to treat various bacterial infections. It is prescribed to adults over the age of 18 for treating bronchitis, pneumonia, and bacterial sinusitis. It belongs to a class of antibiotics that work by inhibiting the growth and spread of bacteria.

Factive works by inhibiting the activity of enzymes involved in bacterial DNA synthesis, replication, and repair, ultimately leading to bacterial death. Specifically, Factive targets the DNA gyrase and topoisomerase IV enzymes, which are essential for DNA replication in bacteria. By inhibiting these enzymes, Factive prevents bacteria from multiplying and spreading, allowing the body's natural immune system to eliminate the remaining bacteria.

Uses and Dosage

Gemifloxacin is an oral tablet that should be taken by mouth with or without food, as prescribed by your doctor. Typically, the medication is taken once daily, and the dosage and treatment length are based on your medical condition and how you respond to treatment. While taking the tablet, Swallow the tablet whole and drink plenty of fluids, unless your doctor advises otherwise. This is usually prescribed once daily or as prescribed by your physician.

Make sure to take the tablet at least two hours before or three hours after taking other products that may interfere with its effectiveness. To achieve the best results, take this antibiotic at evenly spaced times each day, and try to take it at the same time every day to help you remember. Even if your symptoms disappear after a few days, continue taking Gemifloxacin until you have finished the full prescribed amount. Stopping the medication too soon may cause a relapse of the infection. Consult with your pharmacist to identify all the products that may interfere with Gemifloxacin.
