Poppers should not be used in conjuction with Viagra or any Viagra substitute.

Both Viagra and poppers have a similar effect on the blood pressure and when taken together can create a dangerous or even fatal effect.

Poppers and Viagra both possess vasodilatory properties, which causes mild decreases in blood pressure when taken alone. However, poppers and Viagra are taken together, the vasodilator actions of nitrates are significantly incresed, resulting in major hemodynamic compromise and potentially fatal events. PLEASE BE WARNED.
