Proquin XR and other oral formulations of ciprofloxacin are not interchangeable. Proquin XR should be administered orally once daily for 3 days with a main meal of the day, preferably the evening meal. Proquin XR should be administered at least 4 hours before or 2 hours after antacids containing magnesium or aluminum, sucralfate, VIDEX® (didanosine) chewable/buffered tablets or pediatric powder, metal cations such as iron, and multivitamin preparations containing zinc.

Proquin XR tablets should be taken whole and never split, crushed, or chewed. (See CLINICAL PHARMACOLOGY: Drug Interactions)

Impaired Renal Function:

Ciprofloxacin is eliminated primarily by renal excretion; however, the drug is also metabolized and partially cleared through the biliary system of the liver and through the intestine. These alternate pathways of drug elimination appear to compensate for the reduced renal excretion in patients with renal impairment. No dosage adjustment is required for patient with uUTI and mild to moderate renal impairment. The efficacy of Proquin XR has not been studied in patients with severe renal impairment. (See CLINICAL PHARMACOLOGY: Special Populations and PRECAUTIONS: Geriatric Use)

Impaired Liver Function:

No dosage adjustment is required with Proquin XR in patients with stable chronic cirrhosis. However, the pharmacokinetics of ciprofloxacin in patients with acute hepatic insufficiency have not been fully elucidated. (See CLINICAL PHARMACOLOGY: Special Populations)
