What an Esperal Implant Does — and Does Not Do
Esperal is a pellet containing disulfiram. Disulfiram interferes with the way the body breaks down alcohol. If alcohol is consumed while the medicine is active, acetaldehyde can build up and cause flushing, nausea, vomiting, a pounding or racing heartbeat, headache and marked discomfort. A severe reaction can be dangerous. The purpose is deterrence: knowing that alcohol may cause this reaction can reinforce a person's decision not to drink.
The implant is not a cure for alcohol dependence, does not reduce every craving and cannot replace psychological or social support. It is most useful when the patient has already chosen abstinence and has a realistic plan for maintaining it. Counselling, medical follow-up, addiction services and support groups can help address triggers, mental health, relationships and relapse prevention in ways that an implant cannot.
If you are in crisis, feel at risk of harming yourself, or have severe withdrawal symptoms such as confusion, hallucinations, seizures, severe agitation or uncontrolled shaking, an elective implant is not the first step. Seek urgent medical care. Alcohol withdrawal can be dangerous and may require supervised treatment before disulfiram is considered.
