Indications & Clinical Uses

Naltrexone is an opioid antagonist used in the management of substance‑use disorders.

  • Alcohol dependence: reduces cravings and supports sustained abstinence.
  • Opioid dependence: blocks opioid effects to aid detoxification and prevent relapse.
  • Alcohol use disorder: decreases urge to drink and helps maintain sobriety.
  • Opioid use disorder: prevents euphoria from opioid use, supporting long‑term recovery.

How It Works

  • Naltrexone acts as a competitive antagonist at the mu, kappa and delta opioid receptors. By binding to these receptors without activating them, it blocks the effects of both endogenous opioids and exogenous opioid agonists, thereby reducing the rewarding sensations associated with alcohol and opioid use and helping to diminish cravings and prevent relapse.

Side Effects

Naltrexone may cause a range of adverse reactions, which are categorized by frequency.

Common Side Effects

  • Nausea
  • Headache
  • Dizziness
  • Fatigue
  • Insomnia
  • Abdominal pain

Serious or Rare Side Effects

  • Hepatotoxicity (elevated liver enzymes)
  • Severe depression or suicidal thoughts
  • Allergic reactions (rash, pruritus, angioedema)
  • Seizures
  • Acute withdrawal syndrome if opioid‑dependent patients receive the drug abruptly

Precautions & Warnings

Before initiating therapy, clinicians should evaluate patient history and monitor for specific risks.

  • Liver function: assess baseline hepatic enzymes and monitor periodically.
  • Mental health: screen for depression and suicidal ideation; monitor closely.
  • Opioid withdrawal: avoid initiating in patients with recent opioid use to prevent precipitated withdrawal.
  • Renal impairment: use with caution and adjust if necessary.
  • Contraception: advise women of childbearing potential to use effective contraception.
  • Store at ambient temperature: keep in the original pack, protect from moisture.

Avoid Interactions

Naltrexone can interact with several medication classes; some require avoidance while others need monitoring.

Major Interactions (Avoid)

  • Opioid analgesics (e.g., morphine, oxycodone): may precipitate acute withdrawal.
  • Opioid‑containing cough suppressants: can lead to severe withdrawal symptoms.

Moderate Interactions (Monitor Closely)

  • Alcohol: may enhance hepatotoxic risk.
  • Benzodiazepines: combined CNS depression requires observation.
  • Antidepressants (SSRIs, SNRIs): monitor for mood changes.
  • Antihypertensives: possible additive hypotensive effect.
  • NSAIDs: increased risk of liver enzyme elevation.

Frequently Asked Questions

Naltrexone Accord Healthcare is prescribed for the management of alcohol dependence and opioid dependence in adult patients. By blocking opioid receptors, it helps reduce cravings, supports abstinence, and prevents relapse in individuals with these substance‑use disorders.

Naltrexone works as a competitive antagonist at mu, kappa and delta opioid receptors. It binds to these receptors without activating them, thereby blocking the effects of both endogenous opioids and external opioid drugs, which diminishes the rewarding sensations and reduces cravings associated with alcohol and opioid use.

The appropriate dose of Naltrexone Accord Healthcare is determined by the prescribing healthcare professional based on the individual’s medical condition, response to therapy, and other clinical factors. Patients should follow the dosage instructions provided by their prescriber and not adjust the dose on their own.

The safety of Naltrexone during pregnancy and lactation has not been definitively established, and the pregnancy category is listed as unknown. Healthcare providers should weigh the potential benefits against possible risks and consider alternative treatments when treating pregnant or nursing individuals.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request verification of trade or institutional credentials before providing pricing, availability, shipping details and any necessary import documentation.

Naltrexone differs from opioid agonist therapies such as methadone or buprenorphine because it blocks opioid receptors rather than activating them. This antagonistic action eliminates opioid euphoria and reduces cravings, making it suitable for patients who prefer a non‑opioid approach, though it requires a period of opioid‑free status before initiation.

Naltrexone Accord Healthcare should be stored at ambient temperature, preferably below 25 °C. Keep the tablets in the original packaging, protect them from moisture and direct sunlight, and ensure they are out of reach of children.

The medication is supplied as oral tablets intended for swallowing with water. It is taken by mouth as directed by the prescribing clinician, typically on a regular schedule, and should be used consistently to achieve the desired therapeutic effect.

Serious risks include hepatotoxicity, severe depression or suicidal thoughts, allergic reactions such as rash or angioedema, and the potential for precipitated opioid withdrawal if administered to individuals with recent opioid use. Patients should be monitored closely for these events and seek immediate medical attention if they occur.

Naltrexone is contraindicated in individuals with a known hypersensitivity to the drug, those currently undergoing opioid therapy or in acute opioid withdrawal, and patients with severe hepatic impairment. It should also be used with caution in pregnant or breastfeeding women, and under medical supervision in all other cases.
