Published reports have shown it to be effective in the treatment of orgasmic dysfunction in men.Cabergoline, an agonist of dopamine D2 receptors which inhibits prolactin production, was found in a small study to fully restore orgasm in one third of anorgasmic subjects, and partially restore orgasm in another third. Limited data has shown that the drug amantadine may help to relieve SSRI-induced sexual dysfunction. Cyproheptadine, buspirone, stimulants such as amphetamines (including the antidepressant bupropion), nefazodone and yohimbine have been used to treat SSRI-induced anorgasmia. Reducing the SSRI dosage may also resolve anorgasmia problems. See also
