Erectile dysfunction is one of the most common sexual disorders among men, with large number of patients worldwide. This is a multifactorial disease with (non)organic causes while main oral drugs for the treatment are phosphodiesterase type 5 inhibitors (PDE5Is). Currently, sildenafil, vardenafil, tadalafil, udenafil, mirodenafil, lodenafil and avanafil are used. Worldwide use of herbal and dietary supplements for alleviating this problem is on a rise, as many consumers perceive these products as ‘healthier’ and safer as compared to conventional pharmaceutical preparations. However, adulteration of food supplements with PDE5Is and/or its analogues is very common and represents serious public health concern. This review address the issues with pharmacological and toxicological health risks of food supplements adulterated with erectile dysfunction medications.
