Naltrexone can be prescribed for a few different uses.

While both medications are effective, there are some clear benefits to a long-lasting, once-a-month injection.

Naltrexone in pill formmarketed as ReVia and Depadeis still widely used.

It was also the pill form of naltrexone that was initially approved for the treatment of opioid use disorder.

For this indication, the pill is not ideal because of poor treatment adherence.

Because of this, there is poor evidence supporting its benefits in reducing opioid use.

This form of naltrexone could be injected once and beslowly released into the system for a month.

In 2010, the FDA also approved the use of Vivitrol to treat people with opioid dependence.

Research suggests that this leads to greater medication compliance.

It is important to be opioid-free for a certain period of time before you begin receiving naltrexone injections.

Accidental overdose can occur, which may result in death.

Monthly naltrexone injections should not be used by people who have acute hepatitis or liver failure.

Only 6.7% of the group receiving 190 milligrams discontinued treatment due to adverse side effects.

The study was one of the largest trials of subjects treated with medication for alcohol dependence.

The researchers concluded that extended-release naltrexone was well tolerated and significantly reduced heavy drinking in actively drinking individuals.

Severe Side Effects

Severe side effects can also occur in some cases.

If you or a loved one are in immediate danger, call 911.
