Erection problem during sex. Mg?

I would advise you to get a prescription for the medication. The best way to treat erectile dysfunction without medication is by strengthening the pelvic floor muscles with Kegel exercises. Vigora is sildenafil which is a phosphodiesterase 5 inhibitor which works by relaxing the penile smooth muscles and by increasing the blood flow to the penis. It helps to achieve and maintain an erection but only if there is sexual stimulation. Precautions while using Vigora(Sildenafil) are: - Do not have the medicines if you're consuming other tablets such as nitrates or guanylate cyclase stimulators. Your blood pressure could drop to an unsafe level - If you are allergic to sildenafil do not have it - Do not drink alcohol while consuming it as it may cause the blood pressure to drop If you feel any side effects such as dizziness, general weakness or such kindly visit the ER at the earliest.
