Drugs Home > Naltrexone Injection Information

Naltrexone injection (Vivitrol®) is a prescription medicine used as part of a comprehensive treatment plan to help people stop abusing alcohol or opioid medications. It is given in the gluteal muscle once every four weeks. Some people who receive treatment with this drug will develop side effects, such as nausea, vomiting, or reactions at the injection site. However, most people tolerate it well.
Because not everyone can safely use naltrexone injection, it's important to fully understand the safety information on this product before starting treatment. This includes things like possible drug interactions and side effects. Also, let your healthcare provider know if you have any other medical conditions, such as:
  • Liver disease, such as cirrhosis, liver failure, or hepatitis
  • Kidney disease, such as kidney failure (renal failure)
  • Hemophilia, a low platelet count (thrombocytopenia), or other bleeding problems.
