Zenegra to Treat Your Erectile Dysfunction

The active ingredient in Zenegra is Sildenafil Citrate. Sildenafil is used a treatment for men experiencing erectile dysfunction (difficulty maintaining an erection).

Sildenafil’s mission is to work on enzymes of the body called phosphodiesterases and to improve a man’s response to sexual stimulation. These enzymes work mainly in the penis, so the action of sildenafil citrate is primarily limited to the penis.

Sildenafil works to control the enzyme, and by doing so regulates the blood flow out of the penis and thereby helping the patient maintain an erection.

Sildenafil citrate improves the erection of most men, regardless of how long they have had ED. So the time spent with one’s partner can be sexually active and arousing.

Each film-coated tablet contains Sildenafil Citrate equivalent to Sildenafil 100mg. Zenegra contains the active ingredient sildenafil citrate.

Zenegra should be taken approximately 45 minutes prior to having sex, with or without food. If you are sexually stimulated, Zenegra can help you get an erection about 30 to 60 minutes after taking it. The erection can last for up to 4 hours. Alcohol can be consumed while taking Zenegra.

Experts believe impotence affects between 10 and 15 million American men. In 1985, the National Ambulatory Medical Care Survey counted 525,000 doctor-office visits for erectile dysfunction. Impotence usually has a physical cause: such as disease, injury or drug side effects. Any disorder that impairs blood flow in the penis has the potential to cause impotence. Incidence rises with age: about 5 percent of men at the age of 40 and between 15 and 25 percent of men at the age of 65 experience impotence. However, it is not an inevitable part of aging.

Impotence is treatable in all age groups and awareness of this fact has been growing. More men have been seeking help and returning to near-normal sexual activity because of improved, successful treatments for impotence. Urologists, who specialize in problems of the urinary tract, have traditionally treated impotence – especially complications of impotence.

Side Effects

The most common side effects of Sildenafil citrate are headache, flushing of the face and upset stomach. Less common side effects that may occur are temporary changes in colour vision (such as trouble telling the difference between blue and green objects or having a blue colour tinge to them), eyes being more sensitive to light or blurred vision. In rare instances, men have reported an erection that lasts many hours. You should call a doctor immediately if you ever have an erection that lasts more than 4 hours. If not treated right away, permanent damage to your penis could occur.


Before using this drug, tell your doctor your medical history, including any allergies (especially drug allergies), any penis conditions such as fibrosis/scarring, history of painful/prolonged erection (priapism), sickle cell anemia, blood system cancers (such as leukemia or myeloma), peyronie’s disease, eye problems (retina diseases), kidney or liver disease, bleeding disorders or active stomach ulcers, heart diseases, stroke or severe high or low blood pressure. Limit alcohol intake as it may aggravate side effects of this drug. To avoid dizziness and lightheadedness when rising from a seated or lying position, get up slowly. The elderly may be more sensitive to the side effects of this drug, therefore caution is advised in this age group.
