Naltrexone is an opioid antagonist used in the management of substance use disorders. - Alcohol dependence: reduces cravings and helps maintain abstinence. - Opioid dependence: blocks mu‑opioid receptors to prevent relapse. - Relapse prevention in opioid use disorder: diminishes the euphoric effects of opioids, supporting recovery.

Common Side Effects: - Nausea: mild to moderate gastrointestinal upset. - Headache: transient cranial discomfort. - Dizziness: occasional light‑headed sensation. - Fatigue: feeling of reduced energy. - Insomnia: difficulty initiating or maintaining sleep. - Abdominal pain: mild stomach discomfort.

Serious or Rare Side Effects: - Hepatotoxicity: elevated liver enzymes or liver injury. - Severe depression or suicidal thoughts: mood changes requiring immediate evaluation. - Allergic reactions: rash, pruritus, or angioedema. - Hepatic failure: rare but potentially life‑threatening. - Severe hypotension: marked drop in blood pressure.

Before initiating therapy, consider the following precautions. - Assess liver function: monitor hepatic enzymes prior to and during treatment. - Avoid in acute hepatitis: contraindicated in active liver disease. - Caution in renal impairment: adjust monitoring as needed. - Do not combine with opioid analgesics: may precipitate acute withdrawal. - Pregnancy and breastfeeding: use only if potential benefit justifies potential risk. - Store at ambient temperature: keep in the original pack, protect from moisture and light.
