(See WARNINGS and PRECAUTIONS.)
Dosage should be adjusted according to the indication for therapy, severity of symptoms and the response of the patient.
Geriatric Patients
Dose adjustment such as reducing the total dose administered at each dosing or increasing the dosing interval should be considered in elderly patients with renal impairment (creatinine clearance ≤ 70 mL/min/1.73m2). Final dose adjustment should be based upon integration of clinical efficacy and safety considerations. (See CLINICAL PHARMACOLOGY and PRECAUTIONS).
Patients with Renal Impairment
In subjects with renal impairment (creatinine clearance ≤ 70 mL/min/1.73m2), dose adjustment such as reducing the total dose administered at each dosing or increasing the dosing interval should be considered. (See CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION).
INJECTABLE, 100 mg/mL (Not for use in pediatric patients)
Usual Adult Dosage
2 mL (200 mg) t.i.d. or q.i.d. intramuscularly.
NOTE: The injectable form is intended for intramuscular administration only; it is not recommended for intravenous use.
Intramuscular administration may cause pain, stinging, burning, redness and swelling at the site of injection. Such effects may be minimized by deep injection into the upper outer quadrant of the gluteal region, and by avoiding the escape of solution along the route.
