The information at Drugs.com is not a substitute for medical advice. ALWAYS consult your doctor or pharmacist.

The usual dose of FLOXIN® (ofloxacin tablets) Tablets is 200 mg to 400 mg orally every 12 h as described in the following dosing chart. These recommendations apply to patients with normal renal function (i.e., creatinine clearance >50 mL/min). For patients with altered renal function (i.e., creatinine clearance ≤50 mL/min), see the Patients with Impaired Renal Function Subsection.

Antacids containing calcium, magnesium, or aluminum; sucralfate; divalent or trivalent cations such as iron; or multivitamins containing zinc; or Videx® (didanosine) should not be taken within the two-hour period before or within the two-hour period after taking ofloxacin. (See PRECAUTIONS.)

Patients with Impaired Renal Function

Dosage should be adjusted for patients with a creatinine clearance ≤50 mL/min. After a normal initial dose, dosage should be adjusted as follows:

Creatinine Clearance Maintenance Dose Frequency
20–50 mL/min the usual recommended unit dose q24h
<20 mL/min 1/2 the usual recommended unit dose q24h

When only the serum creatinine is known, the following formula may be used to estimate creatinine clearance.

Men: Creatinine clearance (mL/min) = Weight (kg) × (140-age)
72 × serum creatinine (mg/dL)
Women: 0.85 × the value calculated for men.

The serum creatinine should represent a steady-state of renal function.

Patients with Cirrhosis

The excretion of ofloxacin may be reduced in patients with severe liver function disorders (e.g., cirrhosis with or without ascites). A maximum dose of 400 mg of ofloxacin per day should therefore not be exceeded.
