Proquin XR

How Supplied


To reduce the development of drug-resistant bacteria and maintain the effectiveness of Proquin XR (ciprofloxacin hcl) and other antibacterial drugs, Proquin XR (ciprofloxacin hcl) should be used only to treat uncomplicated urinary tract infections that are strongly suspected to be caused by bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Uncomplicated Urinary Tract Infections

Proquin XR (ciprofloxacin hcl) is indicated for the treatment of uncomplicated urinary tract infections (acute cystitis) caused by susceptible strains of Escherichia coli and Klebsiella pneumoniae.

Limitations of Use

Proquin XR is not interchangeable with other ciprofloxacin extended-release or immediate release oral formulations.

The safety and efficacy of Proquin XR (ciprofloxacin hcl) in treating pyelonephritis, complicated urinary tract infections, and infections other than uncomplicated urinary tract infections have not been demonstrated.


Proquin XR (ciprofloxacin hcl) 500 mg tablets should be administered orally once daily for 3 days with a main meal of the day, preferably the evening meal.

Proquin XR (ciprofloxacin hcl) tablets should be taken whole and never split, crushed, or chewed.

Concomitant administration of ciprofloxacin with milk products or calcium-fortified juices alone should be avoided since decreased absorption is possible [see DRUG INTERACTIONS].
