Some of the yohimbine was synthetic. Reported side effects of yohimbe include high blood pressure, stomachache, elevated heart rate, anxiety, headaches, insomnia, and sweating. Serious side effects are possible: According to the National Institutes of Health , yohimbe use has been associated with heart attacks and seizures NIH, Yohimbe may be dangerous for people with certain medical conditions or to take in conjunction with certain medications.
People with high blood pressure, liver disease, kidney disease, benign prostate hypertrophy, or mental health conditions such as depression, bipolar disorder, or post-traumatic stress disorder should not take yohimbe MSKCC, n.
Taking high doses of yohimbe has been reported to be fatal in medical research Anderson, ED, the inability to keep or maintain an erection sufficient for satisfying sex, is the most common sexual dysfunction. Frequent ED or worsening ED symptoms can be an early warning sign of more serious health problems like heart disease, stroke, high blood pressure, diabetes, depression, or a hormone imbalance.
If you choose to try and treat ED with an herbal supplement, you might be overlooking a larger medical issue. Erectile dysfunction. Last updated December 10, As previously indicated, cases of ingestion of up to 3 g have not proved fatal. Table II indicates several cases of yohimbine ingestion and their respective symptoms, along with the two presented case studies for comparison purposes. Unfortunately, in all but one of these cited literature cases, yohimbine concentrations were not measured and correlating concentrations with the observed symptoms and behavior was difficult.
The case involved a male who presented to the hospital in an unconscious state and was given diazepam for the recurrent seizures. After it was quickly discovered that the patient had ingested a large amount of the alkaloid, he was administered clonidine, urapidil and labetalol as a preventative measure to counteract the sympathomimetic effects. Due to its short half-life, treating the symptoms allowed the patient to metabolize the drug down from toxic ranges within hours.
If the subject in Giampreti had not received medical attention, it is plausible that he may have perished. It is important to note that in the Maricopa case, as well as the Giampreti case, the peak concentration of yohimbine may not have been observed. It is suggested that a peak serum concentration will be observed approximately 1 h after ingestion 6. Therefore, in both the Giampreti and Case 1, yohimbine concentrations may be an underestimation of the actual concentrations.
Previously reported cases of yohimbine intoxication for comparison with the presented cases [adopted from Giampreti et al. Information regarding these factors is not readily available; one must use caution in the comparison of the described cases with each other and with Giampreti. It is interesting to note that both Maricopa County and Los Angeles County detected yohimbine as an incidental finding with their respective basic drug extraction and instrumentation.
Although neither laboratory's intention nor scope was to detect yohimbine at a therapeutic concentration, it certainly was beneficial for both laboratories to be able to detect and recognize the identity of the drug. In conclusion, the detection of yohimbine in the blood was extremely beneficial and provided the necessary information for the Medical Examiner to determine the final cause and manner of death as yohimbine intoxication and accidental.

The levels of dehydroepiandrosterone and free testosterone tended to be higher in the responder group, but the levels in both groups were well into the age-adjusted normal ranges. Androgens play a part in peripheral erectile activity, but they are not necessary for the central arousal stimulation of yohimbine, 36 in which norepinephrine release acts as an inhibitor antagonist.
These peripheral effects are prompting the search for new alpha-2 adrenergic antagonists The positive response in our patients was enhanced with the higher dose of yohimbine, a phenomenon noted previously. When yohimbine is ineffective alone, it may be useful in combination with other treatment modalities, as has been shown with naloxone 39 or trazodone.
We have presented objective evidence that yohimbine has a positive effect in men with organic erectile dysfunction. Our study was observational with dose-escalation just to see if there was any rationale to expect any effect in men with organic erectile dysfunction, especially in men who do not have the risk factor of tobacco abuse. The next step would be a double-blind, placebo-controlled study using yohimbine in smokers vs non-smokers to verify the current observation.
We believe that our data justify such a trial. Yohimbine will never be a first-line drug for erectile dysfunction, but may be useful in subsets of men with mild disease or few risk factors. Yohimbine might also be useful in combination therapy with other treatment modalities such as sildenafil and intraurethral alprostadil, when they do not produce adequate effects alone, as has already been shown with naloxone 39 or trazedone.
