From the Guidelines

Testosterone gel is not commonly associated with muscle fasciculations, but it may potentially cause them in some individuals due to its effects on neuromuscular function and electrolyte balance. The provided evidence does not directly address the relationship between testosterone gel and muscle fasciculations 1. However, it is known that testosterone can influence calcium channel activity and neurotransmitter function, which might trigger involuntary muscle contractions in some individuals.

Key Considerations

  • The evidence from the American College of Physicians suggests that testosterone treatment can improve vitality and fatigue, but it does not provide information on muscle fasciculations specifically 1.
  • A review of 38 randomized controlled trials found that testosterone therapy resulted in small improvements in sexual functioning and quality of life, but it did not assess the risk of muscle fasciculations 1.
  • If you experience persistent or bothersome fasciculations while using testosterone gel, you should consult your healthcare provider to rule out other potential causes and consider adjusting your dosage or checking your hormone levels and electrolytes.

Important Factors to Consider

  • Testosterone gel is generally well-tolerated, but it can cause side effects such as skin irritation, acne, and increased risk of prostate cancer 1.
  • The evidence for the long-term safety of testosterone treatment is lacking, and most studies excluded men with recent cardiovascular disease 1.
  • It is essential to weigh the potential benefits and risks of testosterone gel treatment and to monitor patients closely for any adverse effects, including muscle fasciculations.

Recommendations for Clinical Practice

  • Continue using prescribed testosterone gel as directed unless advised otherwise by your healthcare provider.
  • Monitor patients for any adverse effects, including muscle fasciculations, and adjust treatment as needed.
  • Consider alternative treatments or formulations if patients experience persistent or bothersome side effects.

From the Research

Testosterone Gel and Muscle Fasciculations

  • There are no research papers provided that directly address the question of whether testosterone gel can cause muscle fasciculations 2, 3, 4, 5, 6.
  • The studies available discuss the pharmacokinetics, efficacy, and safety of various testosterone gel formulations in hypogonadal men, but do not mention muscle fasciculations as a potential side effect.
  • The provided evidence focuses on the absorption, bioavailability, and steady-state levels of testosterone achieved with different gel formulations, as well as their safety and tolerability in clinical trials 2, 3, 4, 5, 6.
  • None of the studies report muscle fasciculations as an adverse event or side effect associated with the use of testosterone gel.
