How Long Does The Vivitrol Shot Last?

The injectable naltrexone, known as Vivitrol, is a monthly shot that is used to treat opioid use disorder (OUD) and alcohol use disorder (AUD), or alcoholism.

How Long Does A Vivitrol Injection Last?

Vivitrol can only be prescribed and administered by an approved healthcare professional, so monthly appointments are required as part of an addiction recovery program with Vivitrol.

You need to be alcohol- or opioid-free for seven to 14 days before receiving the Vivitrol shot.

Once the shot has been received, it lasts for four weeks.

How Does Vivitrol Last For A Month?

Vivitrol contains the prescription medication, naltrexone.

Each injection contains 380 mg of Vivitrol in a 4 mL solution and is injected into the muscle of the buttocks.

Intramuscular injection allows for the medication to be absorbed into the bloodstream slowly, and in the case of Vivitrol, it takes about four weeks for all the medication to be absorbed.

The location of the injection alternates between each side of the buttocks, since a side effect of Vivitrol can be injection site irritation.
