Ginseng treatment improves the sexual side effects of methadone maintenance treatment

Abstract

BACKGROUND: While methadone maintenance therapy (MMT) in patients with opioid use disorder (OUD) decreases the risk of substance use relapses and criminal and risky sexual behavior, a major disadvantage is its negative impact on sexual function. In the present study we tested whether, compared to placebo, ginseng extract ameliorates methadone-related sexual dysfunction among female and male patients with OUD and receiving MMT. METHOD: A total of 74 patients (26 females: mean age: M=39.0 years; 48 males; mean age: 40.64 years) took part in a double-blind, randomized and placebo-controlled study. Female and male patients were separately randomly assigned either to the ginseng or to a placebo condition. At the beginning of the study and four weeks later, patients completed questionnaires on sexual function. RESULTS: Irrespective of gender, sexual function improved over time, but more so in the ginseng condition than in the placebo condition. CONCLUSIONS: Ginseng appears to counteract the sexual dysfunction resulting from methadone use in both female and male patients with OUD and undergoing MMT.
