Viagra consumer information

Viagra (brand name sildenafil) is a prescription medication that is used for treating erectile dysfunction in men. It was the first drug to be approved by the FDA for treating male impotence. Viagra works by stimulating increased blood flow into the penis which results in stronger and more durable erections upon sexual excitement, Viagra is not an aphrodisiac and won't increase your libido, so it will take sexual stimulation to experience an erection after taking Viagra.

Viagra should never be taken in conjunction with drugs based on nitrates, which are usually prescribed for angina and heart issues. These drugs include nitroglycerinisosorbide dinitrate and isosorbide mononitrate as well as a group of street drugs known as "poppers". Using Viagra in conjunction with these medication leads to a severe drop in blood pressure that can be very harmful and even lethal. Make sure that at least 4 hours have passed since you've used nitrates before using Viagra in order to assure that the medication has cleared away from your body.

Certain conditions will require your dosage of Viagra to be reviewed. So make sure to inform your doctor if you have any of the following before using Viagra:

problems with heart or hear rhythm
recent strokes, heart attacks, heart failure, heart rhythm problems or any other cardiovascular issues
blood pressure problems
coronary artery disease
liver or kidney issues
blood cell disorders
bleeding disorders
stomach ulcer
retinitis pigmentosa
physically deformed penis
restrictions on sexual activity

While using Viagra some people have experienced drop in blood flow to the optic nerve in the eye, which has resulted in temporary vision problems. Only a small number of men have complained about this effect, most of them having vision problems, heart and blood pressure problems, diabetes or other serious health concerns. Viagra only increases the risk of this effect in people prone to vision problems and is not the actual cause of the problem.

As any prescription medication Viagra can cause certain side effects when used. Some of them are mild and will wear off with time, while others are more serious and require medical assistance as soon as possible. Make sure to contact your doctor immediately if you experience any of the following:

sudden vision or hearing problems

heartbeat problems
swelling in your hands, ankles, or feet
feeling short of breath;
feeling light-headed, fainting
