VIAGRA—the proven step to start something all over again
If you're one of the millions of men who suffer from erectile dysfunction or ED (also called impotence), now is the time to find a new start with the breakthrough oral treatment: VIAGRA® (sildenafil citrate). VIAGRA works by improving a man's response to sexual stimulation. So with VIAGRA, a touch or a glance from your partner can again lead to something more.
VIAGRA is the #1 prescribed treatment for erectile dysfunction. In the United States, nearly 10 million men have reclaimed their sex life by taking VIAGRA. Doctors in the United States have prescribed VIAGRA more than 39 million times.
Up to 82% of men experience improved erections with 100-mg VIAGRA. That means that up to 4 out of every 5 men who try VIAGRA benefit from it (compared to 1 out of 4 who used a sugar pill). VIAGRA improves erections in most men regardless of how long they have had ED, how severe it is, or how old they are. And the effectiveness of VIAGRA has been proven in clinical studies of thousands of patients.
VIAGRA is a prescription medication, so you'll need to talk to your healthcare provider to find out if it's right for you. Be sure to ask your healthcare provider if your heart is healthy enough to handle the extra strain of sexual activity. If you have chest pains, dizziness, or nausea during sex, stop and immediately tell your healthcare provider. The most common side effects of VIAGRA are headache, facial flushing, and upset stomach. Less commonly, bluish vision, blurred vision, or sensitivity to light may briefly occur. In the rare event of an erection lasting more than 4 hours, seek immediate medical help. Remember to protect yourself and your partner from sexually transmitted diseases.
How do I know if VIAGRA is right for me?
You'll need to see a healthcare provider to find out if VIAGRA is right for you. It's important to know that VIAGRA isn't for everyone. If you're a man who uses nitrate drugs, like nitroglycerin (drugs commonly used for the treatment of chest pains), never take VIAGRA. Your blood pressure could suddenly drop to an unsafe or life-threatening level. VIAGRA must never be used by men taking nitrates of any kind, any time. Other medications may interact with VIAGRA and change the way VIAGRA works. It's important to tell your doctor about any medications you take, both prescription and nonprescription. Like many medications, your healthcare provider may have to adjust your initial VIAGRA dosage if it doesn't produce the desired results or you're bothered by side effects.
How VIAGRA works
VIAGRA enables many men with ED to respond to sexual stimulation. When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the penis. As the arteries in the penis expand and harden, the veins that normally carry blood away from the penis become compressed, restricting the blood flow out of the penis. With more blood flowing in and less flowing out, the penis enlarges, resulting in an erection.
If the nerves or blood vessels associated with this process aren't working properly, a man may not be able to get an erection. VIAGRA increases blood flow to the penis, so that when a man is sexually aroused, he can get and keep an erection. When the sexual encounter is over, the erection goes away.
