The recommended dose of Campral is two 333 mg tablets (each dose should total 666 mg) taken three times daily. A lower dose may be effective in some patients.

Although dosing may be done without regard to meals, dosing with meals was employed during clinical trials and is suggested in those patients who regularly eat three meals daily.

Treatment with Campral should be initiated as soon as possible after the period of alcohol withdrawal, when the patient has achieved abstinence, and should be maintained if the patient relapses. Campral should be used as part of a comprehensive psychosocial treatment program.

Dosage in Renal Impairment

For patients with moderate renal impairment (creatinine clearance of 30-50 mL/min), a starting dose of one 333 mg tablet taken three times daily is recommended. Campral is contraindicated in patients with severe renal impairment (creatinine clearance of ≤30 mL/min).
