Indications & Clinical Uses

Naltrexone acts on the opioid system and is indicated for conditions related to alcohol and opioid use.

  • Alcohol dependence: reduces cravings and risk of relapse in patients with alcohol use disorder.
  • Opioid dependence: blocks opioid receptors to prevent euphoria and supports detoxification in opioid use disorder.
  • Alcohol use disorder: assists in maintaining long‑term abstinence.

How It Works

  • Naltrexone Hydrochloride is a competitive antagonist at the mu‑opioid receptors in the central nervous system. By binding to these receptors without activating them, it blocks the effects of endogenous opioids and exogenous opioid drugs, thereby reducing dopamine‑mediated reward pathways that underlie alcohol and opioid reinforcement.

Side Effects

Naltrexone may be associated with several adverse reactions, ranging from mild to serious.

Common Side Effects

  • Nausea
  • Headache
  • Dizziness
  • Fatigue
  • Insomnia

Serious or Rare Side Effects

  • Hepatotoxicity (elevated liver enzymes or liver injury)
  • Severe allergic reactions, including anaphylaxis
  • Depression or emergence of suicidal thoughts

Precautions & Warnings

Before initiating therapy with Naltrexone, several precautions should be considered.

  • Liver function assessment: evaluate hepatic enzymes prior to treatment.
  • Contraindication in acute hepatitis: avoid use in patients with active liver disease.
  • Monitor for depression: observe patients for mood changes or suicidal ideation.
  • Caution in renal impairment: adjust if severe renal dysfunction is present.
  • Pregnancy and breastfeeding: safety not established; weigh risks and benefits.
  • Store at ambient temperature: keep in original packaging, protect from moisture.

Avoid Interactions

Naltrexone can interact with other medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

  • Opioid agonists (e.g., morphine, heroin): can precipitate acute withdrawal.
  • Hepatotoxic drugs (e.g., isoniazid, high‑dose acetaminophen): increase risk of liver injury.
  • Disulfiram: combined use may heighten hepatotoxic potential.

Moderate Interactions (Monitor Closely)

  • Alcohol: concurrent use may worsen liver function.
  • Antidepressants (e.g., SSRIs): monitor for mood changes.
  • Benzodiazepines: may increase sedation.
  • Methadone or buprenorphine: dose adjustments may be required.

Frequently Asked Questions

Naltrexone Accord contains Naltrexone Hydrochloride, an opioid antagonist prescribed to help manage alcohol dependence and opioid dependence by reducing cravings and blocking the reinforcing effects of these substances.

Naltrexone acts as a competitive antagonist at the mu‑opioid receptors in the central nervous system, preventing endogenous and exogenous opioids from activating the receptor, thereby diminishing dopamine‑mediated reward pathways associated with alcohol and opioid use.

The dosage regimen for Naltrexone Accord is determined by the prescribing clinician based on the individual’s condition, treatment goals, and clinical response. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Safety data for Naltrexone in pregnancy and lactation are limited; therefore, it should only be used when the potential benefit justifies the potential risk to the fetus or infant, and the decision should be made by a qualified health professional.

To place an order, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Compared with opioid agonist therapies such as methadone or buprenorphine, Naltrexone provides a non‑opioid, antagonist approach that blocks opioid effects rather than substituting them. This can be advantageous for patients seeking an opioid‑free regimen but may require complete detoxification before initiation.

Naltrexone Accord should be stored at ambient temperature, below 25 °C, in its original container, protected from moisture and direct sunlight. Keep the product out of reach of children and do not use if the packaging is damaged.

Naltrexone Accord is taken orally, usually as a tablet or capsule, with or without food as directed by the prescriber. The medication should be swallowed whole with a glass of water and not crushed or chewed unless specifically instructed.

The most serious risks include potential hepatotoxicity, severe allergic reactions such as anaphylaxis, and the emergence of depression or suicidal thoughts. Patients should be monitored regularly for liver function and mood changes, and any severe symptoms should prompt immediate medical attention.

Naltrexone is contraindicated in individuals with acute hepatitis, severe liver impairment, or those currently dependent on opioid analgesics without having completed detoxification, as it can precipitate withdrawal. It should also be used with caution in patients with renal impairment and those with a history of severe depression.
