GENERAL INFORMATION ABOUT VIAGRAtop

VIAGRA is a prescription medicine used to treat erectile dysfunction (ED). You will not get an erection just by taking this medicine. VIAGRA helps a man with ED get and keep an erection only when he is sexually stimulated.

VIAGRA is not for use in women or children.

It is not known if VIAGRA is safe and effective in women or children under 18 years of age.

VIAGRA can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines.

Do not take VIAGRA if you take any other medicines called "nitrates." Nitrates are used to treat chest pain (angina). A sudden drop in blood pressure can cause you to feel dizzy, faint, or have a heart attack or stroke. Do not take VIAGRA if you take medicines called guanylate cyclase stimulators which include:

  • Riociguat (Adempas®) a medicine that treats pulmonary arterial hypertension and chronic-thromboembolic pulmonary hypertension.

Tell all your healthcare providers that you take VIAGRA. If you need emergency medical care for a heart problem, it will be important for your healthcare provider to know when you last took VIAGRA.
Stop sexual activity and get medical help right away if you get symptoms such as chest pain, dizziness, or nausea during sex.

Sexual activity can put an extra strain on your heart, especially if your heart is already weak from a heart attack or heart disease. Ask your doctor if your heart is healthy enough to handle the extra strain of having sex.

VIAGRA does not protect you or your partner from getting sexually transmitted diseases, including HIV—the virus that causes AIDS.

VIAGRA works for men with ED by increasing blood flow to the penis so you can get and keep an erection hard enough for sex.* VIAGRA only works when you are sexually stimulated. It has been proven to help guys with all degrees of ED. VIAGRA usually starts to work within 30-60 minutes. And you only take it when you need it.

*Individual results may vary.

VIAGRA usually starts to work within 30-60 minutes. And you only take it when you need it. VIAGRA can be taken with or without food. If you take VIAGRA after a high-fat meal (such as a cheeseburger and french fries), it may take a little longer to start working.

If you’ve tried VIAGRA and you’re still not getting results, ask your doctor to see if adjusting your dose might help. Remember, VIAGRA should not be taken more than one time a day. VIAGRA may not be right for every man, but it has been shown to help approximately 4 out of 5 men get and keep erections hard enough for sex at doses of 50 mg or 100 mg.*

*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.

ABOUT COUNTERFEIT VIAGRAtop

VIAGRA is one of the most counterfeited drugs in the world. Counterfeit medicine is fake medicine. It may be contaminated or contain the wrong or no active ingredient. They could have the right active ingredient but at the wrong dose. Counterfeit drugs are illegal and may be harmful to your health. Many consumers may not know that the medicines they've purchased are counterfeits.

What we found in counterfeit VIAGRA:

  • Blue printer ink
  • Amphetamines, also known as “speed”
  • Metronidazole, a powerful antibiotic that could cause an allergic reaction, diarrhea, or vomiting
  • Too much active ingredient (or not enough), which may cause you harm
  • Binding agents, such as drywall, that prevent the tablet from breaking down in your system

The primary danger in taking a counterfeit medicine is that you are putting something into your body that not only may not help your current condition, but more alarmingly could result in harmful effects to your overall health.

No. There are lots of treatments that claim to be “herbal VIAGRA.” They can be found online or even at some drugstores. But there’s no such thing as “herbal VIAGRA.”

The FDA has never approved any form of “herbal VIAGRA” as a treatment for erectile dysfunction. Plus, these treatments can be fake or unsafe. Many have been recalled.

You can only get VIAGRA by prescription from your doctor or healthcare provider.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. VIAGRA may affect the way other medicines work, and other medicines may affect the way VIAGRA works, causing side effects.

Before you take VIAGRA, tell your healthcare provider if you:
  • have or have had heart problems such as a heart attack, irregular heartbeat, angina, chest pain, narrowing of the aortic valve or heart failure
  • have had heart surgery within the last 6 months
  • have pulmonary hypertension
  • have had a stroke
  • have low blood pressure, or high blood pressure that is not controlled

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)

ABOUT ERECTILE DYSFUNCTION (ED)top

ED is the medical term for difficulties getting and keeping an erection. ED happens when not enough blood flows to the penis, preventing an erection. It is a sexual health problem that affects about 30 million men in the U.S. Please ask your doctor or healthcare provider to get more information about your specific symptoms.

ED is often caused by something physical, such as a disease, injury, or side effects from other drugs.

Medical conditions that can cause ED:

  • Depression
  • Diabetes
  • Heart disease
  • High blood pressure
  • High cholesterol
  • Obesity
  • Prostate cancer treatment
  • Spinal cord injury

Medications that can cause ED:
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

Yes. 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 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

You can talk with your regular doctor. Or you can talk to a specialist, like a urologist. Either one can prescribe VIAGRA if they decide it’s right for you.
