DESCRIPTION

Viagra (Sildenafil) is an Rx medication that is used to treat erectile dysfunction (ED) - this is the inability for a man to get or keep an erection - long enough for sex. It happens when not enough blood flows to the penis, thereby preventing an erection.

ED affects about 30 million men in the U.S. alone and some guys with ED find it difficult to either get or keep an erection every time they try to have sex. For others, ED symptoms can happen just occasionally. Either way, you should know that you’re not alone.

ED is often caused by something physical, such as a disease, injury, or side effects from other drugs. Diseases most commonly associated with ED are high blood pressure, high cholesterol, and diabetes. Some lifestyle and psychological factors can also play a role in causing ED, such as smoking, drinking, stress, and depression.

Although most cases of ED have a physical cause, thoughts that lead to depression, worry, or anxiety can also cause ED. Even when ED has a physical cause, it can be made worse if it leads to depression and worry.

In some men, ED is a side effect of some medications. These medications might include drugs used to treat:

• High blood pressure
• Heart disease
• Depression

Some lifestyle and psychological factors can play a role in causing ED, such as smoking, drinking, and stress because they may lead to conditions that affect blood circulation.

There are things you can do each day to improve your circulation and avoid some of the conditions that can lead to ED:

• Find ways to stay more active (mowing the lawn, walking the dog)
• Help manage your weight by eating healthy food and watching your portion size
• Drink less alcohol
• Quit smoking. The results can be significant
• Look for ways to reduce stress in your daily life

It might interest you to know, that Viagra (Sildenafil) helped approximately 4 out of 5 men to get and maintain erections hard enough for sex*.

(*Seventy-two percent, 80%, and 85% of the patients on 25 mg, 50 mg, and 100 mg of VIAGRA, respectively, achieved erections hard enough for sex, compared to 50% on placebo. Also, men taking VIAGRA showed an improvement in their ability to get and keep an erection versus those who took placebo.)

Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors, and treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation and this increased blood flow can cause an erection.

If you are taking Sildenafil to treat erectile dysfunction, you should know that it does not cure erectile dysfunction or increase sexual desire. Further, Sildenafil does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV). Please practice "safe sex" such as using latex condoms. Consult your doctor or pharmacist for more details.

Can Other Medicines Affect Sildenafil?

Tell your doctor if you take any of the following:

• nitrate drugs for chest pain or heart problems. This includes nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, and others), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket). Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite ("poppers"). Taking Sildenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
• medicines called guanylate cyclase stimulators such as Adempas (riociguat)
• medicines called alpha-blockers such as Hytrin (terazosin HCl), Flomax (tamsulosin HCl), Cardura (doxazosin mesylate), Minipress (prazosin HCl), Uroxatral (alfuzosin HCl), Jalyn (dutasteride and tamsulosin HCl), or Rapaflo (silodosin).
• Alpha-blockers are sometimes prescribed for prostate problems or high blood pressure. In some patients, the use of VIAGRA with alpha-blockers can lead to a drop in blood pressure or to fainting
• medicines called HIV protease inhibitors, such as ritonavir (Norvir), indinavir sulfate (Crixivan), saquinavir (Fortovase or Invirase), or atazanavir sulfate (Reyataz)
• some types of oral antifungal medicines, such as ketoconazole (Nizoral) and itraconazole Sporanox)
• some types of antibiotics, such as clarithromycin (Biaxin), telithromycin (Ketek), or erythromycin
• other medicines that treat high blood pressure
• other medicines or treatments for ED
• Viagra contains Sildenafil, which is the same medicine found in another drug called REVATIO. REVATIO is used to treat a rare disease called pulmonary arterial hypertension (PAH).
• Viagra should not be used with REVATIO or with other PAH treatments containing Sildenafil or any other PDE5 inhibitors (such as Adcirca [tadalafil]).

During sexual activity, if you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away. You could be having a serious side effect of Sildenafil.

Do not take Sildenafil more than once a day. Allow 24 hours to pass between doses. Do not take Viagra while also taking Revatio, unless your doctor tells you to.

Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.

Sildenafil can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking Sildenafil, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old. It is not clear whether Sildenafil is the actual cause of vision loss.

Stop using Sildenafil and get emergency medical help if you have sudden vision loss.

What about driving and using machinery?

No studies on the effects on the ability to drive and use machines have been performed.

As dizziness and altered vision were reported in clinical trials with Sildenafil, patients should be aware of how they react to Sildenafil, before driving or operating machinery.
