Product Description:

Naltrexone (complete generic name: naltrexone hydrochloride) is a medication widely used in the management of alcohol use disorder and opioid use disorder. It belongs to the class of opioid antagonists and works by blocking opioid receptors in the brain. By doing so, it reduces the euphoric effects and cravings associated with alcohol and opioid use, helping individuals maintain recovery as part of a comprehensive treatment program that includes counseling and behavioral support.

Naltrexone hydrochloride is available in oral tablet form and as an extended-release intramuscular injection. After administration, the medication begins to act within a short period, helping to reduce the rewarding effects of opioids and alcohol. Over time, consistent use under medical supervision can support long-term recovery and reduce the risk of relapse. The injectable formulation is often used for patients who require a long-acting treatment option with once-monthly dosing.

In addition to its approved indications, naltrexone may sometimes be prescribed off-label for certain other addictive or compulsive conditions under the guidance of healthcare professionals. Because it blocks opioid effects, patients must be opioid-free before starting treatment. Naltrexone therapy should always be initiated and monitored by qualified healthcare providers to ensure safe and effective use.
