Understanding the Side Effects of Naltrexone in Alcohol Use Disorder Treatment

Naltrexone is an effective medication widely used in the treatment of alcohol use disorder, helping many individuals reduce their alcohol dependence. While it is important to be aware of the side effects associated with Naltrexone, understanding how to manage these can significantly improve the treatment experience and outcomes. Dr. Joseph Volpicelli provides detailed insights into what patients might expect when starting this medication and how to effectively address these side effects.

Primary Side Effects

According to Dr.Volpicelli, the most common initial side effect of Naltrexone in patients is nausea, with some cases escalating to vomiting. "When we've done studies, we compare side effects to people who take Naltrexone versus people who take a placebo pill," explains Dr. Volpicelli. The results show that nausea is significantly more prevalent among those taking Naltrexone but generally resolves within "a few days to a week, maybe two weeks."

Less Common and Psychological Side Effects

Beyond gastrointestinal disturbances, other side effects include headaches and an unusual sensation described by patients as feeling "a little bit different." Dr. Volpicelli notes that these are less consistently reported and are often hard to distinctly attribute to Naltrexone compared to placebo effects. There are also reports in clinical observations and literature of increased anxiety, a decrease in pleasure from normally enjoyable activities, and feelings of depression. These psychological effects are crucial for healthcare providers to monitor, as they can significantly impact the patient's quality of life.

Effects on Pleasure Linked to Pain

An intriguing aspect of Naltrexone's action is its impact on the pleasure derived from activities associated with pain, a result of its mechanism on the endogenous opioid system in the brain. Dr. Volpicelli points out, "Certain activities are pleasurable because they release endogenous opiates in your brain and typically those activities include some degree of displeasure or pain." For example, patients have reported a diminished pleasure in eating highly spicy foods or engaging in intense physical activities like ultra-marathon running. This effect might be beneficial for some, as it helps reduce behaviors like binge eating or self-harm among individuals who find such actions compulsively pleasurable.

Management of Side Effects

For those experiencing intense side effects, especially when starting the medication while heavily drinking, Dr. Volpicelli stresses the importance of timing the initiation of Naltrexone. "If in the middle of a drinking episode your endogenous opioids are already released... you can bring on a withdrawal reaction." To mitigate this, he suggests beginning Naltrexone after a brief period of abstinence. He also recommends strategies like taking the medication with food to slow absorption, reducing the dosage temporarily, or switching to an extended-release form to ensure more stable medication levels in the body, which can help minimize side effects like nausea.

Summary of Side Effects Discussed:

• Nausea and Vomiting: Most common and typically resolves within the first few weeks.
• Headaches and Unusual Sensations: Less frequent, with patients reporting feelings of being "a little bit different."
• Psychological Effects: Includes increased anxiety, reduced pleasure from normally enjoyable activities, and occasional feelings of depression.
• Pain-Associated Pleasure Changes: Decreased enjoyment of activities that involve pain and pleasure, such as eating spicy foods or engaging in ultra-marathon running.
• Impact on Specific Behaviors: Some patients report reduced compulsive behaviors like binge eating or self-harm.

The Role of Support Systems

Dr. Volpicelli underscores the importance of social support alongside medical treatment: "Social supports are critically important for people in their recovery... it’s also important to have psychosocial support to help you get through the process." Whether through peer support groups like AA, counseling, family support, or even joining Thrive's program, these networks play a vital role in the recovery journey.

In conclusion, while Naltrexone is a powerful tool in the treatment of alcohol use disorder, understanding and managing its side effects are key to achieving the best outcomes.  With these insights from Dr. Volpicelli patients and healthcare providers can better prepare for and manage the side effects of Naltrexone, enhancing the overall effectiveness of the treatment for alcohol use disorder. Through proactive management and support, patients can achieve significant progress in their recovery journey.
