Medical uses:
Four 100 mg diamond-shaped tablets of branded Viagra
1) Sexual dysfunction
The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete intercourse). Its use is now one of the standard treatment for erectile dysfunction, including for men with diabetes mellitus.
2) Pulmonary hypertension
While sildenafil improves some markers of disease in people with pulmonary arterial hypertension, it does not appear to affect the risk of death or serious side effects as of 2014.
3) Antidepressant-associated sexual dysfunction
Tentative evidence suggests that sildenafil may help men who experience antidepressant-induced erectile dysfunction.
4) Altitude sickness
Sildenafil appears to improve some risk factors for high-altitude pulmonary edema but it is unclear whether or not it affects the rate of the condition itself as of 2008.
How does Sildenafil Works?
Erectile dysfunction (sometimes called impotence) means that you cannot get or maintain a proper erection. There are several causes, the most common being due to a narrowing of the arteries that take blood to the penis.
Sildenafil works by preventing the action of a chemical in your body, called phosphodiesterase type-5. This helps to widen (relax) blood vessels and improves the flow of blood to the penis following sexual stimulation. This helps to maintain an erection.
Before taking sildenafil:
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking sildenafil it is important that your doctor knows:
If you have any disease, injury or deformity of your penis.
If you have a heart condition, or blood vessel disease.
If you have had an eye condition causing loss of vision.
If you have low blood pressure or angina.
If you have any problems with the way your liver works or with the way your kidneys work.
If you have had a stroke or a heart attack.
If you have a condition which causes bleeding, such as a stomach ulcer.
If you have sickle cell disease.
If you have ever had bone marrow cancer or leukaemia.
If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines, and recreational drugs.
If you have ever had an allergic reaction to a medicine.
