Sildigra 250mg, which contains sildenafil, is typically used to treat erectile dysfunction. For most people, sildenafil starts working within 30 to 60 minutes after taking it. However, the exact time can vary based on individual factors like metabolism, the presence of food in the stomach, and overall health. Taking it on an empty stomach might help it work faster. If you have specific concerns or experience any issues, it’s a good idea to consult with a healthcare professional.
