Patients with renal impairment or renal failure, especially those with a creatinine clearance of 50 mL/minute or less, should have their systemic ofloxacin dosage adjusted. It was previously thought that antibiotics may decrease the effectiveness of OCs containing estrogens due to stimulation of metabolism or a reduction in enterohepatic circulation via changes in GI flora. Drospirenone; Estradiol: (Moderate) It would be prudent to recommend alternative or additional contraception when oral contraceptives (OCs) are used in conjunction with antibiotics.
