Yohimbine Effects and Recommendations

Introduction to Yohimbine

• The American Urological Association does not recommend the use of yohimbine for the treatment of erectile dysfunction due to its potentially serious side effects, including elevated blood pressure, increased heart rate, anxiety, irritability, and tremors, without proven therapeutic benefit 1, 2, 3

Mechanism of Action and Physiological Effects

• Yohimbine is an indole alkaloid chemically similar to reserpine, acting primarily as a selective inhibitor of alpha-2-adrenergic receptors, leading to increased adrenergic activity in the body 3

Cardiovascular Effects

• Elevated blood pressure (systolic and diastolic) can occur due to yohimbine use 3
• Increased heart rate (tachycardia) is a potential effect of yohimbine 3
• These effects can be particularly problematic in individuals with pre-existing cardiovascular risk factors, as noted by the American College of Cardiology 4

Neurological and Psychological Effects

• Irritability and increased motor activity can be caused by yohimbine 3
• Tremors are a potential side effect of yohimbine use 3

Therapeutic Efficacy

• The efficacy of yohimbine for treating erectile dysfunction has not been conclusively demonstrated, despite its historical use for this purpose 3, 5
• The American Urological Association does not recommend yohimbine for erectile dysfunction treatment due to lack of proven efficacy and potential side effects 1, 2, 3

Preoperative Considerations

• It is recommended to stop yohimbine at least 2 weeks before surgery due to its effects on blood pressure, as advised in the Mayo Clinic Proceedings 6
