Sildigra 250 mg, which contains sildenafil, is designed to help treat erectile dysfunction (ED) by increasing blood flow to the penis. However, it's important to note that it will not automatically make you "hard" or cause an erection without sexual stimulation. Sildigra 250mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), allowing for increased blood flow in response to sexual arousal. If you have concerns about dosage or effectiveness, it's essential to consult with a healthcare provider. They can provide guidance tailored to your needs.
