Femalegra 100 mg contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. In men, sildenafil is commonly used to treat erectile dysfunction (ED), but in women, it is used for a different purpose. Femalegra is often prescribed to women who experience sexual arousal disorder or female sexual dysfunction. This condition can manifest as a persistent lack of sexual desire, difficulty becoming sexually aroused, or inability to achieve orgasm. Sildenafil citrate works by increasing blood flow to the genital area in women, which may help improve sexual arousal and sensitivity. It does not directly address issues of desire or other psychological factors that can contribute to sexual dysfunction.
