Product details

Viagra is the medicine that brought erectile dysfunction into the open and gave millions of men a straightforward answer. Its active ingredient, sildenafil, relaxes the blood vessels that feed the penis, so that when arousal happens, blood can flow in freely and an erection follows as it should.

The important thing to understand is that it does not work on its own. Sexual stimulation is still needed; sildenafil simply makes sure the body can respond to it. Taken around an hour before intimacy, it opens a comfortable window of several hours in which things work as nature intended.

Developed by Pfizer and refined over decades of use, it remains the name most men reach for first, and for good reason.

  • Improves blood flow so the body can respond to arousal
  • Best taken about an hour before sex
  • Comes in three strengths to match your response

It is a prescription medicine and must never be combined with nitrate heart medicines, as the two together can cause a dangerous drop in blood pressure.

Take one tablet around an hour before sex, with or without food, though a heavy or fatty meal can delay the effect. Do not take more than one dose in twenty four hours. Sexual stimulation is still needed for it to work.

Sildenafil citrate, the active ingredient.

Headache, facial flushing, a stuffy nose and indigestion are the usual mild effects. Some men notice a brief blue tinge to their vision. Prolonged erection and sudden sensory changes are rare but need urgent attention.

Never take with nitrate heart medicines or recreational nitrites, as the combination can cause a dangerous fall in blood pressure. Caution with alpha blockers. Seek urgent care for an erection lasting beyond four hours or sudden loss of sight or hearing.
