Femalegra 100 mg contains Sildenafil Citrate, the same active ingredient used in many erectile dysfunction (ED) medications like Viagra. While Femalegra is marketed primarily for women to help with ***** arousal issues, the Sildenafil in it works by increasing blood flow, which can also help older men with ED. In summary: Sildenafil (the active ingredient) is proven effective for erectile dysfunction in men, including older men. Femalegra 100 mg could theoretically work similarly for men, but it's usually marketed for female use. For older men with ED, medications specifically prescribed for men like Viagra, Vigora, or Zudena might be more appropriate and better studied. It's important for older men to consult a healthcare provider before using any ED medication, especially if they have other health conditions or take other medications. If you want, I can provide detailed info on how Femalegra works or suggest other ED treatments suitable for older men.
