There is growing problem with medications and herbal products sold via the Internet containing inappropriate quantities or the absence of active ingredients or whose ingredients are inaccurately represented, which may or may not be harmful to the user. We report on a counterfeit medication whose active ingredient is dapoxetine, a short-acting selective serotonin reuptake inhibitor, for the treatment of premature ejaculation. The counterfeit dapoxetine was sold on the Internet and contained an undisclosed phosphodiesterase type 5 inhibitor ingredient. Moreover, the Internet site only sold a 60 mg dose and did not indicate that the recommended starting dose of the medication for all patients is 30 mg.
