Viagra (Sildenafil)

Viagra, which is used to treat erectile dysfunction in men, relaxes muscles and increases blood flow to particular areas.

Effects and dangers

Taking Viagra with a nitrate medicine can cause a sudden and serious decrease in blood pressure. Nitrate drugs include recreational pills such as amyl nitrite.

Amyl nitrite (Poppers)

Poppers are a nitrite-based drug. Amyl nitrite is used medically to ease chest pain caused by angina.

Effects and dangers

The effects, which are instantaneous and brief, but intense, are caused by a sudden surge of blood to the heart and brain.

Regular use can cause skin problems around the mouth and nose.

As poppers reduce blood pressure, they are dangerous for people with anaemia, glaucoma, breathing or heart problems, and may lead to heart attacks.

Poppers are inhaled and can be fatal if swallowed.
