Naltrexone is a potent, long-acting opioid receptor antagonist. It works by binding to the mu-opioid receptors in the brain, effectively blocking the euphoric and sedative effects (the "high") of opioids like heroin, morphine, and codeine. When used for alcohol dependence, Naltrexone reduces the craving for alcohol and the pleasurable feelings associated with drinking by modulating the body's reward system. Unlike some other treatments, Naltrexone is not addictive and does not cause a "high" or physical dependence.
In Nigeria, Naltrexone 50mg is a critical clinical tool in comprehensive rehabilitation programs. It is available through registered pharmacies like Sanlive Pharmacy to ensure patients and healthcare facilities receive authentic, high-purity tablets manufactured under strict international quality standards to support long-term sobriety.
Important: This is a prescription-only medication. It must only be used as part of a complete treatment program including counseling and social support. You must be opioid-free for at least 7 to 10 days before starting Naltrexone. Taking Naltrexone while opioids are still in your system will trigger sudden, severe, and potentially dangerous withdrawal symptoms (precipitated withdrawal). Because Naltrexone is processed by the liver, regular Liver Function Tests (LFTs) are required during treatment.
Naltrexone 50mg Tablets are primarily used to:
Prevent relapse in patients formerly dependent on opioids (heroin, oxycodone, etc.)
Treat alcohol dependence by reducing cravings and the urge to drink heavily
Block the effects of accidentally or intentionally consumed opioids
Support long-term behavioral changes as part of a structured recovery plan
Help maintain a "plateau" in recovery where the brain's reward system can heal

Fatigue or difficulty sleeping (insomnia)
Anxiety or nervousness
Muscle or joint pain

Will Naltrexone make me feel sick if I drink alcohol?
No. Unlike Disulfiram (Antabuse), Naltrexone does not make you physically ill if you drink. Instead, it makes drinking less "rewarding" by removing the buzz, which helps you stop wanting to drink over time.
What happens if I take a painkiller like Tramadol while on Naltrexone?
Naltrexone will block the pain-relieving effects of Tramadol or any other opioid. If you try to take higher doses of opioids to "break through" the block, you run a very high risk of a fatal overdose (respiratory failure).
How long do I need to stay on this medicine?
Most recovery programs recommend staying on Naltrexone for at least 3 to 6 months, though some patients continue for a year or more to solidify their sobriety. Your doctor will determine the best duration for your specific case.
