Suhagra 25 mg is a lower-dose version of the medication Suhagra, which contains Sildenafil Citrate as its active ingredient. Sildenafil is commonly used to treat erectile dysfunction (ED) by improving blood flow to the penis, helping men achieve and maintain an erection when sexually stimulated. The 25 mg dose is typically prescribed for men who may need a lower starting dose, or for those who have sensitivity to the medication.
