Ciprofloxacin is used to treat patients with bacterial infections such as pneumonia, anthrax, syphilis, gonorrhea, bronchitis, gastroenteritis and plague. This antibiotic is also used to fight against infections of the throat, skin, ears, nose, sinus, bones, respiratory system and urinary tract.

Ciprofloxacin is an anti-biotic, which is a member of the fluoroquinolone family. It helps fight against infections caused by bacteria. It is used to treat severe bacterial infections including pneumonia, respiratory or urinary tract infections, gonorrhea, anthrax, gastroenteritis as well as infections of the sinus, bones, skin and joints. It is also effective in treating septicemic plague.

Ciprofloxacin works by destroying the existing bacteria, that cause infections, from within the body and preventing the growth of new bacteria. The regular synthesis of DNA requires the presence of enzymes of bacterial DNA gyrase and topoisomerase IV. Ciprofloxacin inhibits the activity of DNA gyrase, thus preventing DNA relaxation, encouraging the damage of double stranded DNA and inhibiting the cell division of bacteria. In this way, Ciprofloxacin is efficient in fighting against bacterial infections within the body.

Ciprofloxacin is available in many forms such as tablets, oral solution, ophthalmic ointment and a solution that can be injected. It is important to read the label of this medicine and follow the exact guidelines of the doctor’s prescription. Do not take an extra pill to make up for a missed dose, if you forget to take a dose. Instead, just continue with the next dose.

If you notice these symptoms, it is advisable to stop taking this medicine immediately and contact your doctor.
