Description
Brand Viagra has the sildenafil drug as its main ingredient. It is a muscle relaxant that works by relaxing the walls of blood vessels.
This serves to increase the blood supply to specific parts of the body. It is used in the treatment of erectile dysfunction in men.
A variation of sildenafil used regardless of gender is Revatio, which can increase the capacity of both male and female users to exercise.
Important data
Never take brand Viagra in conjunction with Revatio as it can lead to an adverse reaction and a possible overdose of sildenafil.
Tell your doctor about all medication that you are currently on, regardless of ingredients.
Never take brand Viagra if you are also on any type of nitrate drug. These are used to treat angina and heart diseases.
Nitrate drugs include nitroglycerin, isosorbide mono- and di-nitrate, and recreational drugs as well (poppers).
Tell your doctor immediately and go to the hospital if you have an erection that lasts for more than 4 hours.
Tell your doctor if you have a history of heart diseases, arrhythmia, arterial conditions, heart attacks, strokes, heart failure, high and low blood pressure, liver and kidney failure, sickle cell anemia, hemophilia, leukemia, ulcers and hereditary eye disorders.
Brand Viagra (and most other impotency drugs) have been shown to cut off the supply of blood to the optic nerve, which leads to a sudden loss in vision.
Not usually taken by women, but it is not thought to have an adverse effect on unborn children. However, it is advisable to tell a doctor before getting pregnant.

Missed doses and overdose
If you have been prescribed brand Viagra, take a missed dose as soon as you remember. If it is nearly time for the next dose on your schedule, ignore the one you missed.
