A prescription medication called sildigra 250mg is used to treat erectile dysfunction (ED). The active component in it is sildenafil. This medication increases blood flow to the penis during sexual stimulation, which leads to an erection. However, there could be a variety of adverse effects, ranging from mild to severe, from using it. Flushing, indigestion, headaches, back pain, and muscle aches are common mild side effects. Usually, these adverse effects are transient in nature and disappear on their own as the body adjusts to the drug.
