Always follow your doctor’s specific instructions and consult them if you have any questions or experience side effects.
Oral sildenafil works by enhancing the effects of nitric oxide, a natural chemical the body produces that relaxes muscles in the penis.
This increased relaxation allows for improved blood flow into the penile tissues when a man is sexually aroused. By facilitating this blood flow, sildenafil helps achieve and maintain an erection.
It is important to note that sildenafil is effective only with sexual stimulation and does not increase sexual desire.
