Naltrexone is a drug used as a complete treatment solution for drug abuse and alcoholism. Naltrexone and recovery choices makes an excellent combination to fight addiction. It belongs to a class of drugs known as opiate antagonists. It is available under the names of Revia, Vivitrol and Depia.
Naltrexone blocks the parts of the brain that “feel” pleasure after drinking or drug abuse. Slowly it reduces the desire of drinking or drug abuse. The drug should be taken according to the advice of a doctor otherwise it may cause withdrawal symptoms and side effects.
The medicine can be taken orally and intravenously. Intravenous is mostly recommended to treat patients addicted to heroin, morphine and other opioids. It is not used to treat drug overdose.
Naltrexone is not the solution but in combination with rehabilitation, counseling and support groups helps in achieving sobriety. Research has documented that patient who are on naltrexone have a 2 times higher incidence of remaining clean and abstinent than being on a placebo alone.
