Naltrexone 5mg

Naltrexone 5mg Uses

Naltrexone 5mg is prescribed to: Treat opioid dependence – It blocks the effects of opioids, preventing the “high” and reducing cravings. Manage alcohol use disorder (AUD) – It helps reduce the urge to drink and prevents relapse in recovering alcoholics. Support weight loss treatments (off-label use) – Some studies suggest Naltrexone may help curb food cravings when combined with bupropion. Treat impulse control disorders – It has been used off-label for conditions such as compulsive gambling and self-harm behaviors. Naltrexone is not a cure for addiction but an essential tool in long-term recovery programs.

How Does Naltrexone 5mg Work?

Naltrexone 5mg works by blocking opioid receptors in the brain, which play a crucial role in addiction and pleasure responses. Its primary functions include: Opioid Receptor Antagonism: Naltrexone binds to opioid receptors without activating them, preventing opioids like heroin or painkillers from producing their euphoric effects. Craving Reduction: It helps reduce cravings for opioids and alcohol, making it easier for individuals to maintain sobriety. Prevention of Relapse: By eliminating the pleasurable effects of substances, Naltrexone discourages relapse in those recovering from addiction. Long-Lasting Action: Unlike opioid-based treatments like methadone, Naltrexone does not cause physical dependence and has a long duration of action. This mechanism makes Naltrexone a valuable option for addiction treatment and relapse prevention.

Follow these instructions for safe and effective use of Naltrexone 5mg: Dosage: Take exactly as prescribed by your doctor, usually once daily or as part of a structured dosing plan. Timing: Take the medication at the same time every day to maintain stable blood levels. With or Without Food: Naltrexone can be taken with or without food, but taking it with a meal may reduce stomach upset. Avoid Opioid Use: Ensure you have been opioid-free for at least 7–10 days before starting Naltrexone to prevent withdrawal symptoms.
