Naltrexone is an opioid antagonist indicated for conditions related to alcohol and opioid use disorders.

- Alcohol dependence: reduces cravings and supports maintenance of abstinence. - Opioid dependence: blocks the effects of opioids, facilitating detoxification and preventing relapse. - Relapse prevention: helps sustain recovery by diminishing the rewarding effects of alcohol or opioids.

Naltrexone may cause a range of adverse reactions, which vary in frequency and severity.

Common Side Effects: - Nausea - Headache - Dizziness - Fatigue - Insomnia - Abdominal pain

Serious or Rare Side Effects: - Hepatotoxicity (elevated liver enzymes, hepatitis) - Severe depression or suicidal ideation - Allergic reactions such as rash, angioedema, or anaphylaxis - Hepatic failure - Severe hypotension - Acute withdrawal syndrome when combined with opioids

Before initiating therapy, clinicians should evaluate patient-specific risk factors and monitor for adverse events.

- Liver function assessment: check baseline hepatic enzymes. - Mental health monitoring: watch for depression or suicidal thoughts. - Contraindication in acute hepatitis: avoid use during active liver disease. - Caution in renal impairment: adjust monitoring as needed. - Avoid concurrent opioid analgesics: may precipitate withdrawal. - Store at ambient temperature: keep in the original pack, protect from moisture.

Naltrexone can interact with several drug classes, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid): - Opioid agonists (e.g., morphine, oxycodone): may cause acute withdrawal. - Opioid‑containing cough syrups or anesthesia agents. - Disulfiram (potential additive hepatotoxicity).

Moderate Interactions (Monitor Closely): - Benzodiazepines: enhanced central nervous system depression. - Hepatotoxic drugs (e.g., isoniazid, methotrexate): monitor liver enzymes. - Alcohol: may increase risk of liver injury.
