Naltrexone, also known as Vivitrol, is a medication that is commonly prescribed as part of a treatment plan for alcohol use disorder and opioid use disorder.
Various side effects, including strange or vivid dreams, can occur while taking Naltrexone tablets or receiving Vivitrol shots for opioid addiction.
How Does Naltrexone Affect Sleep?
Naltrexone is an opioid antagonist that binds to and blocks opioid receptors. Through this action, naltrexone modulates natural endorphins in the body.
The modulation of natural endorphins, known as endogenous opioids, in the body can affect the levels of dopamine and serotonin, two neurotransmitters, in the brain.
According to some research, increases in serotonin and dopamine that are caused by medications like naltrexone or certain antidepressants, may cause more intense dreams.
Common sleep-related effects of naltrexone include:
- increased vividness of dreams
- insomnia (difficulty falling or staying asleep)
Sleep-related effects of naltrexone, such as vivid dreams, may not last for the duration of a person’s treatment. For some people, this effect may last only for a few days.
If this issue persists, however, and becomes a deterrent to continued treatment, consider talking to your doctor about suggestions for managing sleep-related concerns.

Factors That Can Affect Naltrexone Effects On Sleep
Not everyone who takes naltrexone for alcohol addiction or opioid use disorder may experience significant disruptions to their sleep cycle or the quality of their sleep.
Vivid dreaming is more likely in people who are taking higher doses of naltrexone and those who have a history of insomnia or poor sleep quality.
Furthermore, vivid dreams can also be influenced by personal factors, such as stress, the use of other medications, mental health issues, and longer periods of rapid eye movement (REM) sleep.
What Can Help With Weird Dreams While Taking Naltrexone?
Quality of sleep, and the types of dreams people have, can be influenced by a range of factors—some of which may be out of one’s immediate control.
Feelings of nervousness, anxiety, or major changes in a person’s life—such as seeking help for drug or alcohol abuse—may affect a person’s sleep.
What may help address sleep disturbances while taking naltrexone:
- meditation or relaxation techniques
- cognitive behavioral therapy
- regular physical activity
- muscle relaxation
- stress reduction
- maintaining a regular sleep schedule
Sleep disturbances may often occur as a result of other stressors in a person’s life or poor sleep hygiene. Addressing these co-occurring issues may help improve sleep in addiction recovery.
