Xanax, Valium, Klonopin, Ativan — benzodiazepine dependency requires a medically supervised taper. Withdrawal can be dangerous. Find safe detox programs.
Along with alcohol, benzodiazepines are the only class of substances where withdrawal can cause potentially fatal seizures. Never stop benzodiazepines abruptly if you've been using them regularly — even at prescribed doses. A medical taper — gradually reducing the dose — is the standard of care and often requires a medical detox setting for higher-dose dependency.
