Treatment of Impotence
PDE5 drugs can cause life-threatening reactions when mixed with certain other types of drugs. The best known reaction is when PDE5 drugs are mixed with nitroglycerin or other drugs in the nitrate family (such as isosorbide). Nitrates are usually used for heart disease, but some men take one of these drugs for other reasons.
Trade names for nitrate drugs include Nitrostat, NitroQuick, Imdur, Isordil, Dilatrate, Ismo, Monoket, Nitrol, Nitrobid, Minitran, and Nitrodur.
Keep in mind that PDE5 drugs should not be used by men who take nitrate drugs at all, even if you use a nitrate drug only on rare occasions.
Do you use any nitrates, even on only rare occasions?
