It is known that PDE5 inhibitors are not recommended to use with nitrate drugs for chest pain or heart problems.  The list of nitrates is great we offer the most commonly used nitrates: nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, Minitran, Deponit, Transderm-Nitro), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket). Still if you want to use Levitra and you are on nitrates, discuss it with your doctor to define a special schedule of drugs dosing and time necessary to pass between them.
