Common uses
While a male is sexually aroused, his body produced two types of chemicals. One allows flow of blood in penis and the other causes decrease in erections. Cipla Silagra does the work of inhibiting the second chemical which results in erect penis.
Before using
Do not take sildenafil if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, and others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket). Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite ("poppers"). Taking sildenafil with a nitrate medicine can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack.
A small number of patients have had a sudden loss of eyesight after taking sildenafil. This type of vision loss is caused by decreased blood flow to the optic nerve of the eye. It is not clear whether sildenafil is the actual cause of such vision loss. Sudden vision loss with sildenafil use has occurred most often in people with heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old.
Before taking sildenafil, tell your doctor if you have:
heart disease or heart rhythm problems;
a recent history (in the past 6 months) of a heart attack, stroke, or heart rhythm disorder;
congestive heart failure;
high or low blood pressure;
coronary artery disease;
liver disease;
kidney disease;
a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;
a bleeding disorder such as hemophilia;
a stomach ulcer;
retinitis pigmentosa (an inherited condition of the eye);
a physical deformity of the penis (such as Peyronie's disease); or
if you have been told you should not have sexual intercourse for health reasons.
If you have any of these conditions, you may not be able to use sildenafil or you may need a dosage adjustment or special tests during treatment.
