Prescription Medications for AUD

Adjunct TherapyCommon name—naltrexoneNaltrexone is used to help you to stay away from alcohol, but it is not a cure for addiction. It may work by blocking the high that makes you crave alcohol. However, it will not, prevent you from experiencing the effects of alcohol. Naltrexone is available as a pill and an injection in the muscle.Possible side effects include:
  • Liver damage
  • Headache
  • Anxiety, nervousness, and insomnia
  • Fatigue
  • Nausea and vomiting
  • Adverse reactions at the injection site
Deterrent TherapyCommon name—disulfiramDisulfiram helps you overcome your drinking problem by making you very sick if you drink alcohol. However, it is not a cure for addiction. While you take this medication, and for at least 12 hours before you begin taking it, you should not drink even the smallest amount of alcohol. You should not use any foods, products, or medications that contain alcohol, nor should you come into contact with any chemicals that contain alcohol while using this medication. If you have been diagnosed with heart disease or schizophrenia, talk to your doctor before taking this medication. Do not take this medication if you are allergic to disulfiram. If you use alcohol while taking this medication, you may experience some of the following symptoms:
  • Nausea and vomiting
  • Chest pain
  • Lightheadedness, which may lead to fainting
  • Sweating and flushing
  • Difficulty breathing
  • Confusion
  • Weakness
  • Rapid heart beat
  • Drowsiness
If you experience mild reactions, you will most likely recover completely. However, reactions may worsen leading to breathing problems, heart problems, seizure, unconsciousness, and possibly death. Symptoms will last from 30 minutes to several hours. If you have mild or moderate reactions, see a doctor for help. If you experience severe reactions, call for emergency medical services right away.AcamprosateAcamprosate reduces your craving for alcohol by inhibiting a chemical in your brain called gamma aminobutyric acid (GABA). Several studies have indicated that it may help you remain abstinent.Possible side effects include:
  • Diarrhea
  • Headache
  • Weakness
  • Rarely, suicidal thoughts
BenzodiazepinesCommon names include:
  • Diazepam
  • Chlordiazepoxide
  • Lorazepam
  • Oxazepam
Benzodiazepines are anti-anxiety drugs that may be used to relieve withdrawal symptoms of alcoholism and reduce the risk of seizures. These drugs produce a sedative effect. Benzodiazepines are usually not used for long periods of time because they can lead to dependence and may cause withdrawal symptoms when discontinued. Possible side effects include:
  • Drowsiness
  • Lightheadedness
