Usual Adult Dose for Muscle Spasm:
Initial dose: 5 mg orally 3 times a day. Based on individual patient response, the dose may be increased to either 7.5 mg or 10 mg 3 times a day. Alternate doses include the 15 mg extended release capsule or 30 mg extended release capsule orally once a day.
Usual Geriatric Dose for Muscle Spasm:

The manufacturer suggests an initial dose in the elderly of 5 mg, titrating slowly upward based on individual patient response. Extended release formulations are not recommended for use in elderly patients.
Usual Pediatric Dose for Muscle Spasm:
