Key facts

  • Sildenafil (the ingredient in Viagra, Kamagra and many generics) is a PDE5 inhibitor. It relaxes blood vessels so more blood reaches the penis during arousal, and it only works with sexual stimulation.
  • For erectile dysfunction you take it 30 to 60 minutes before sex; the effect lasts 4 to 6 hours. A heavy or fatty meal delays it.
  • Never take sildenafil with nitrate heart medicines (glyceryl trinitrate, isosorbide) or the pulmonary-hypertension drug riociguat. Together they can drop your blood pressure to dangerous levels.
  • Seek urgent care for an erection lasting more than 4 hours, or sudden loss of vision or hearing.

What sildenafil treats

Sildenafil treats erectile dysfunction, the inability to get or keep an erection firm enough for sex. A lower-dose version (sold as Revatio) treats pulmonary arterial hypertension, high blood pressure in the arteries between the heart and lungs, where it relaxes those vessels to ease the strain on the heart. It is not a treatment for angina, and it does not increase desire.

How sildenafil works

An erection depends on a signal molecule called cyclic GMP relaxing the blood vessels in the penis so they fill with blood. An enzyme, PDE5, breaks that molecule down. Sildenafil blocks PDE5, so cyclic GMP lasts longer and the vessels stay relaxed once arousal begins. In the lungs the same mechanism widens the pulmonary arteries.

Before you take it

  • Do not use sildenafil if you take any nitrate medicine or riociguat, or if a doctor has told you sex is too risky for your heart.
  • Tell your prescriber about alpha-blockers, other blood-pressure medicines, recent heart attack or stroke, very low or uncontrolled high blood pressure, and severe liver or kidney disease. These may change your dose or rule the drug out.
  • An erection lasting over 4 hours (priapism) can permanently damage the penis. Men with sickle cell disease, myeloma or leukaemia carry a higher risk.
  • Buy only from a licensed pharmacy. Sildenafil is among the most counterfeited medicines in the world, and fakes with wrong doses or contaminants are a documented cause of harm.

Side effects

Common effects fade as the dose wears off: headache, facial flushing, a blocked or runny nose, indigestion, and a temporary blue tinge to vision or light sensitivity.

Stop and seek urgent medical care for any of these:

  • An erection lasting more than 4 hours.
  • Sudden loss or dimming of vision in one or both eyes.
  • Sudden hearing loss, sometimes with ringing or dizziness.
  • Chest pain, a fast or irregular heartbeat, or fainting.

Safety essentials

  • The nitrate rule is absolute: no sildenafil within 24 hours of any nitrate, and no nitrate given for chest pain while sildenafil is in your system. If you get chest pain during sex, tell emergency staff you have taken it.
  • Grapefruit juice and some antifungal and HIV medicines raise sildenafil levels; your prescriber may lower the dose.
  • Do not take more than one dose in 24 hours, and do not combine it with other erectile-dysfunction treatments.
