What is the most important information I should know about tadalafil?

Do not take tadalafil if you are allergic to it, or if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin (Nitro Dur, Nitrolingual, Nitrostat, Transderm Nitro, and others), isosorbide dinitrate (Dilatrate, Isordil, Isochron), isosorbide mononitrate (Imdur, ISMO, Monoket), or recreational drugs such as amyl nitrate or nitrite ("poppers").
