Sildigra 250mg typically contains sildenafil, and a dosage of 250 mg is quite high. This dosage is not commonly prescribed, as standard doses for sildenafil are usually between 25 mg and 100 mg. Taking such a high dose can increase the risk of side effects without necessarily improving effectiveness. Always talk to a healthcare professional before taking high doses of any medication to ensure it's safe for you. Higher doses can lead to increased side effects, such as headaches, flushing, or even more serious issues like vision changes. More is not always better; many individuals find effective results at lower doses.
