CENFORCE-50 - CENTURION LABORATORIES


Cenforce-50 (Generic Viagra, Sildenafil Citrate, manufactured by Centurion Laboratories, India) relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body.

Before taking this medicine

You should not use Cenforce-50 if you are allergic to Sildenafil Citrate, if you take other medicines to treat pulmonary arterial hypertension, such as riociguat (Adempas). Do not take Cenforce-50 if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (“poppers”). Taking Cenforce-50 with a nitrate medicine can cause a sudden and serious decrease in blood pressure.

To make sure Cenforce-50 is safe for you, tell your doctor about your other medical conditions, especially:

heart disease or heart rhythm problems, coronary artery disease;
a recent history (in the past 6 months) of a heart attack, stroke, or congestive heart failure;
high or low blood pressure;
liver or 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.


Cenforce-50 can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking Sildenafil Citrate, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoked or were over 50 years old. It is not clear whether Sildenafil Citrate is the actual cause of vision loss. Do not give Cenforce-50 to anyone under 18 years old without medical advice.

How should I take Cenforce-50?

Take Cenforce-50 exactly as it was prescribed for you. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. Cenforce-50 is usually taken only when needed, 30 minutes to 1 hour before sexual activity. You may take it up to 4 hours before sexual activity. Do not take Cenforce-50 more than once per day. Cenforce-50 can help you have an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Follow your doctor’s instructions.

What should I avoid while taking Cenforce-50?

Drinking alcohol with this medicine can cause side effects. Grapefruit and grapefruit juice may interact with Sildenafil Citrate and lead to unwanted side effects. Avoid the use of grapefruit products while taking Cenforce-50. Avoid using any other medicines to treat impotence, such as alprostadil or yohimbine, without first talking to your doctor.
