Viagra
Viagra (sildenafil citrate) can be used to treat male impotence, erectile dysfunction being a more accurate term for the condition. Viagra should be taken 40-60 minutes before planned sexual activity and is expected to provide for up to 5 hours of efficiency. However, the result will be better if you attempt having sex right when Viagra become efficient (after 45-60 minutes). Never combine Viagra with isosorbide mononitrate, nitrates and isosorbide dinitrate, as this may result in a sudden drop in blood pressure, If you are not sure whether the drugs you are taking are or are not from those groups, consult your doctor or your pharmacist. Any medical conditions you have or used to have are supposed to be reported to your health care provider before you start using Viagra, especially any of the following ones: leukemia, liver disease, hemophilia, congestive heart failure, coronary artery disease, multiple myeloma, stomach ulcer, high or low blood pressure, heart rhythm problems, condition of the eye, sickle cell anemia, kidney disease, a recent history of a heart attack or stroke, and physical deformity of the penis.
