Vigora Oral Jelly is a sildenafil medicine used for erectile dysfunction in adult men. It comes in a jelly form that may be easier to swallow than tablets, and it is intended to help achieve and maintain an erection during sexual stimulation. Sildenafil is a PDE-5 inhibitor. It relaxes blood vessels in the penis and increases blood flow during arousal, which supports a firmer erection. It does not cause an erection by itself, so sexual stimulation is still needed.
