Ibogaine therapy uses different forms and dosing regimens of ibogaine to treat substance abuse disorders and other conditions. The forms include the root bark of Tabernanthe iboga, total alkaloid extracts, and purified ibogaine hydrochloride. Dosing can involve a single high dose, multiple escalating or de-escalating doses, or linear dosing schedules. Effective single doses typically range from 10-22 mg/kg, most often 15-20 mg/kg, but the appropriate dosing depends on individual patient factors and treatment goals.
