Sildigra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient. Sildenafil citrate works by increasing blood flow to the penis during sexual stimulation, enabling men to achieve and sustain an erection. As with other medications containing sildenafil citrate, it's crucial to take Sildigra 100 mg as prescribed by a healthcare professional and to be aware of potential side effects or interactions with other medications. Common side effects may include headache, flushing, dizziness, blurred vision, and nasal congestion. Serious side effects such as priapism (prolonged erection lasting more than four hours) are rare but require immediate medical attention.
