From the Guidelines
There is no established association between Wellbutrin (Bupropion) and myalgia based on the available evidence. When considering the potential side effects of Wellbutrin, it's essential to weigh the benefits against the risks, prioritizing morbidity, mortality, and quality of life as outcomes. The study by the American College of Physicians 1 provides insight into the adverse events associated with second-generation antidepressants, including Wellbutrin. Key points to consider include:
- The incidence of specific adverse events varies among second-generation antidepressants, with some differences noted in the study.
- Bupropion had a significantly lower rate of sexual adverse events compared to other antidepressants like fluoxetine or sertraline.
- While the study mentions various adverse events, it does not specifically highlight myalgia as a common side effect of Wellbutrin. Given the lack of direct evidence linking Wellbutrin to myalgia, it is reasonable to conclude that myalgia is not a well-established side effect of this medication. However, if a patient experiences muscle aches while taking Wellbutrin, they should follow general advice for managing muscle tension, such as staying hydrated, engaging in gentle exercise, and considering over-the-counter pain relievers for temporary relief, as suggested in the example guidance. Ultimately, the decision to continue or adjust treatment should be made in consultation with a healthcare provider, taking into account the individual patient's response to the medication and their overall health status.
From the FDA Drug Label
There are reports of arthralgia, myalgia, fever with rash and other symptoms of serum sickness suggestive of delayed hypersensitivity Myalgia 3% 2% 6% Musculoskeletal and Connective Tissue Disorders Myalgia 2% 3%
Myalgia is a reported adverse reaction associated with bupropion, occurring in 2-6% of patients in clinical trials 2 2 2.
- Key points:
- Myalgia is a known adverse reaction to bupropion
- The incidence of myalgia varies between 2-6% in clinical trials
- Myalgia is listed as a musculoskeletal and connective tissue disorder associated with bupropion use
- Bupropion can cause a range of adverse reactions, including myalgia, arthralgia, and other symptoms of serum sickness.
From the Research
Association between Wellbutrin (Bupropion) and Myalgia
There is limited direct evidence linking Wellbutrin (Bupropion) to myalgia. However, some studies provide insight into the potential effects of Bupropion on muscle-related symptoms:
- A case study 3 reported a patient experiencing neck stiffness, trismus, and unilateral temporomandibular joint (TMJ) pain and subluxation after increasing the dosage of Bupropion, suggesting a possible dose-related adverse reaction.
- Another study 4 found that Bupropion may be effective in treating neuropathic pain, with most patients experiencing mild side effects such as insomnia, tremor, and gastrointestinal upset, but no direct mention of myalgia.
- Research on the anti-inflammatory action of Bupropion 5 found that it may have pro-inflammatory effects, which could potentially contribute to muscle pain or myalgia, although this is not directly stated in the study.
- A randomized controlled trial 6 on the use of Bupropion for restless legs syndrome found that it did not exacerbate symptoms and may be a reasonable choice for individuals with RLS, but did not specifically address myalgia.
- A case report 7 described a patient developing tardive dyskinesia during Bupropion therapy, which may involve involuntary muscle movements, but this is a distinct condition from myalgia.
