Suhagra 100 mg contains Sildenafil Citrate, the same active ingredient found in Viagra. It's commonly used to treat erectile dysfunction (ED). While Suhagra 100 mg is effective for improving erectile function, it is generally not intended to be taken daily. Suhagra 100 mg is typically used on an as-needed basis. It should be taken about 30 to 60 minutes before sexual activity. The effects generally last for about 4 to 6 hours, allowing for improved erectile function during this time frame. Daily use at this dosage could increase the risk of side effects and might not provide additional benefits compared to as-needed dosing.
