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.
|Infection*||Unit Dose||Frequency||Duration||Daily Dose|
|Acute Bacterial Exacerbation of Chronic Bronchitis||400 mg||q12h||10 days||800 mg|
|Comm. Acquired Pneumonia||400 mg||q12h||10 days||800 mg|
|Uncomplicated Skin and Skin Structure Infections||400 mg||q12h||10 days||800 mg|
|Acute, Uncomplicated Urethral and Cervical Gonorrhea||400 mg||single dose||1 day||400 mg|
|Nongonococcal Cervicitis/Urethritis due to C. trachomatis||300 mg||q12h||7 days||600 mg|
|Mixed Infection of the urethra and cervix due to C. trachomatis and N. gonorrhoeae||300 mg||q12h||7 days||600 mg|
|Acute Pelvic Inflammatory Disease||400 mg||q12h||10–14 days||800 mg|

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.
