Sildigra is a medication containing sildenafil, which is used to treat erectile dysfunction (ED). Sildenafil works by increasing blood flow to the penis, which can help achieve and maintain an erection when sexually aroused. It is important to note that sildenafil is a prescription medication and should only be taken under the guidance of a healthcare professional. A doctor can determine if sildenafil is appropriate for your condition, the correct dosage for your needs, and discuss potential side effects or interactions with other medications you may be taking.
