Naltrexone Reviews

Naltraxone helps alcoholics stay alcohol-free. This medication is to be taken in combination with counseling, support group meetings, and other treatment aspects prescribed by your Doctor. It is not a cure all medication that will stop you from drinking alcohol but it will help to control cravings, making you less interested in drinking alcohol.

Naltraxone works by blocking the “high” feeling that makes you want to use alcohol. It does not have any effects similar to alcohol and can not cause you to develop a dependency. If you choose to drink alcohol while taking Naltraxone it will not stop any of the effects of alcohol, you will become impaired and relapse in your recovery.

Naltraxone can cause you to develop symptoms of withdrawal. It is recommended that people thinking about taking Naltraxone overcome their dependency and work through the withdrawal period before beginning this medication.

Naltraxone is available by Doctors prescription only.
