Femalegra 100 mg is commonly marketed as containing sildenafil citrate 100 mg. Although sildenafil is well established for treating erectile dysfunction in men, it is not an FDA-approved treatment for female sexual dysfunction. Evidence for oral sildenafil in women is mixed. Sildenafil works by inhibiting PDE5 and increasing blood flow. Researchers have investigated whether this might improve genital blood flow, physical arousal, lubrication, or orgasm in some women.
