Does Contrave Affect Your Mood? Understanding the Neuropsychiatric Side Effects

4 min read

Contrave, a weight-loss medication containing a combination of bupropion and naltrexone, has been reported to cause a wide range of mood-related changes in individuals. While some patients may experience an improved sense of well-being, others can face significant neuropsychiatric side effects, including anxiety, irritability, and, in rare cases, suicidal thoughts or manic episodes.

Quick Summary

Contrave can cause a spectrum of mood changes, ranging from a positive effect stemming from the bupropion component to serious side effects like anxiety, irritability, and suicidal ideation. The medication carries a boxed warning from the FDA regarding these neuropsychiatric risks. Close monitoring for behavioral shifts is critical, especially at the start of treatment or following dose adjustments.

Key Points

  • Dual-Component Effect: Contrave's active ingredients, bupropion and naltrexone, both influence the brain's chemistry, which can lead to a variety of mood changes.

  • Serious Psychiatric Risks: The bupropion component carries an FDA boxed warning for increased risk of suicidal thoughts and behaviors, especially in younger adults.

  • Common Negative Effects: Anxiety, agitation, and irritability are frequently reported side effects that result from the drug's effect on neurotransmitters.

  • Mania Risk: Contrave can trigger manic episodes in people with underlying bipolar disorder or a history of the condition.

  • Vigilant Monitoring is Crucial: Patients and caregivers must closely observe for unusual behavioral or mood shifts, particularly when beginning the medication or adjusting the dose.

  • Immediate Medical Attention: Seek help right away if you experience thoughts of suicide, severe agitation, or a manic episode while on Contrave.

The Dual-Action of Contrave's Ingredients

Contrave is a combination medication containing two active components: naltrexone hydrochloride and bupropion hydrochloride. Understanding the function of each ingredient is key to comprehending the potential impact on your mood. The medication works on the central nervous system to help reduce appetite and control food cravings, but these same neurological pathways can influence mood and behavior.

  • Bupropion: This component is an atypical antidepressant and a norepinephrine-dopamine reuptake inhibitor (NDRI), which means it increases levels of dopamine and norepinephrine in the brain. Higher levels of these neurotransmitters can lead to an improved sense of well-being, energy, and mood in some people. However, bupropion can also cause or exacerbate anxiety, agitation, restlessness, and insomnia.
  • Naltrexone: This is an opioid antagonist, typically used to treat alcohol and opioid dependence. In Contrave, it works to block opioid receptors, which is thought to reduce cravings by interfering with the brain's reward system. Naltrexone has also been associated with mood and mental changes, including depression and irritability, though often studied in the context of substance use disorders. Preliminary research suggests that naltrexone can influence negative emotional processing.

Potential Mood-Enhancing Effects

Some individuals starting Contrave may experience positive shifts in their mood. These effects are primarily attributed to the bupropion component, which is a known antidepressant. Positive changes reported by some users may include:

  • An overall lift in mood
  • Increased energy levels
  • A greater sense of well-being
  • Reduced food cravings, which can improve motivation and satisfaction

These positive effects, however, are not universally experienced and should be considered alongside the potential for more adverse neuropsychiatric reactions.

Significant and Common Negative Mood Effects

The impact of Contrave on mood is not always positive and can include a range of serious side effects. These risks have led the FDA to issue a boxed warning, its most serious warning for medications.

FDA Boxed Warning and Suicidal Risk

Contrave contains bupropion, which has caused suicidal thoughts and actions in some people taking it, particularly children, adolescents, and young adults. Although Contrave is not approved for pediatric use, this serious warning is crucial for patients of all ages, and their families, to be aware of. Patients and their caregivers must monitor for new or worsening depression, suicidal thoughts or behaviors, and other unusual mood changes, especially during the first few months of treatment or following a dosage change.

Other Neuropsychiatric Risks

Beyond the boxed warning, patients should be vigilant for a host of other mood-related side effects:

  • Anxiety and Restlessness: Feeling agitated, restless, or nervous is a common side effect.
  • Irritability and Aggression: Some patients report increased irritability, anger, or even aggression.
  • Manic Episodes: The bupropion in Contrave can trigger manic episodes in individuals with a history of bipolar disorder or those with an underlying predisposition.
  • Insomnia and Sleep Disturbances: Trouble sleeping is a very common side effect that can significantly impact mood and mental clarity.
  • Delusions and Psychosis: Though rare, Contrave has been associated with more severe neuropsychiatric symptoms, including hallucinations, paranoia, and delusions.

Monitoring and Communication: A Critical Protocol

Because of the potential for significant mood and behavioral changes, close monitoring and open communication with a healthcare provider are essential when taking Contrave. Families and caregivers should be involved in this process, as they may notice changes that the patient does not.

What to Monitor For

  • Sudden or unusual changes in mood or behavior.
  • Worsening of existing depression or anxiety.
  • Thoughts of self-harm or suicide.
  • Unusually aggressive, angry, or violent behavior.
  • An extreme increase in energy, reckless behavior, or racing thoughts (potential signs of a manic episode).
  • Paranoia or hearing voices that are not there.

Potential Mood Effects: A Comparative Table

Potential Mood Effect Bupropion Component Naltrexone Component Contrave (Combined)
Improved Mood/Energy Common; Primary action for antidepressant use. Indirect; Low doses may boost endorphins. Possible; Some individuals may experience this benefit.
Anxiety/Agitation Common; Reported side effect, especially in initial treatment. Possible; Can occur, often tied to high doses. Common; A frequently reported adverse effect.
Irritability Common; Part of the overall neuropsychiatric side effect profile. Less Common; Reported as a side effect. Common; Resulting from the combination of ingredients.
Suicidal Thoughts/Behavior Black Box Warning; Significant risk, particularly in young adults. Rarely; Case reports exist, but less directly linked. Black Box Warning; A serious risk requiring immediate attention.
Manic/Hypomanic Episodes Risk; Can activate mania in individuals with bipolar disorder. Rarely; One case report noted mania triggered by naltrexone. Risk; Patients with bipolar disorder should be cautious.

When to Contact a Healthcare Provider

It is crucial to act quickly if you or a loved one notice severe mood changes. Stop taking Contrave and call a healthcare provider immediately if you observe symptoms such as:

  • Thoughts about suicide or dying, or attempts to commit suicide.
  • New or worse depression or anxiety.
  • Extreme agitation, restlessness, or panic attacks.
  • Unusual or severe changes in behavior or mood.
  • Increased aggression or violence.
  • An extreme increase in energy and talking.

Conclusion

Does Contrave affect your mood? The answer is a clear and unequivocal yes, but the effects can vary significantly and include both positive and serious negative reactions. Because of the bupropion component, the medication comes with a boxed warning regarding the risk of suicidal thoughts and behaviors. While some may experience an improved mood, a large number of individuals report negative neuropsychiatric side effects such as anxiety, irritability, and insomnia. It is critical for anyone considering or currently taking Contrave to be aware of these potential mood changes and to monitor their mental health closely. Regular communication with your doctor is essential to weigh the benefits of weight loss against the mental health risks and to seek immediate help if severe symptoms arise.
