Naltrexone
• Naltrexone works by blocking opioids from acting on the
brain - this takes away the ability to get high from using
opioids. This makes naltrexone a good option for preventing
relapse, but may not stop all drug cravings.
• A person cannot have any opioids in his/her body when
starting naltrexone. If a person does, withdrawal will be
very strong. Before a clinician starts a patient on naltrexone,
the patient must go through withdrawal under a clinician's
supervision. This period can last anywhere between 7-10
days.
• Naltrexone comes in a pill form that is taken regularly. It is
also available in an extended release form that is injected in
the buttocks. The injection is administered by the clinician in
his/her office once a month.
Medication Use Summary
• Every patient is different, and the right medication is found
when the person feels normal, has little to no side effects,
does not feel withdrawal, and has cravings under control.
• When used correctly, and when the treatment plan is being
followed, these medications can be taken safely for years.
• Any plans to stop taking a medication, change dosage, or
switch medications should always be discussed with the
clinician – this should be a shared decision, with all benefits
and risks discussed and understood between both parties.
• Patients will continue to see the clinician and participate in
counseling and support groups based on the agreed upon
treatment plan.
• Relapse may occur as part of this chronic disease. If a patient
relapses while using medication, the clinician will revise the
treatment plan and treatment goals as needed.
