Generic Naltrexone 50 mg (Naltrexone Hydrochloride, Vivitrol) is used as part of a treatment program for drug or alcohol dependence. Naltrexone is not a permanent cure for drug addiction or alcoholism. It is also used to treat alcoholism by reducing your urge to drink alcohol. This may help you drink less or stop drinking altogether. You should not be drinking at the time you receive your first medication.

How To Take

Take this medication by mouth with or without food, usually 50 milligrams once daily or as directed by your doctor. This medication may be given as part of a program where a health care professional will watch you take the medication. In this case, your doctor may order a higher dose (100-150 milligrams) to be taken every 2-3 days to make it easier to schedule clinic visits. Naltrexone may be taken with food or antacids if stomach upset occurs.


You should be treated with naltrexone only if you have not recently used: any medicine to treat a cold, cough, diarrhea, or pain. Using these medicines in the 7 to 14 days before starting naltrexone can cause sudden symptoms. Call your doctor if you have ongoing or worsening pain, redness, itching, bruising, swelling, or a hard lump where the medicine was injected. Naltrexone can harm your liver. Tell your doctor if you have upper stomach pain, dark urine, or yellowing in the whites of your eyes.
