Viagra (Sildenafil) – one of the best known drugs of all time!

ViagraWhat is Viagra?

Viagra (Sildenafil) is one of the best known drugs of all time. Nearly every adult in America has heard of the drug and can tell you what it does.
Viagra is the trade name for a drug called Sildenafil. Viagra is one of a class of drugs known as PDE-5 (Phosphodiesterase type 5) inhibitors. Viagra and the other PDE-5 inhibitors can help men with erectile dysfunction (male impotence) by enhancing the erectile response when a man is sexually stimulated. For men suffering from erectile dysfunction (or ”ED”) Viagra increases the blood flow to the penis and leads to a firmer and longer lasting erection.

When taking Viagra, keep in mind:

  1. Take Viagra exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
  2. You must be SEXUALLY STIMULATED for VIAGRA (sildenafil citrate) to work. You will not get an erection just by taking this medicine.
  3. Viagra is usually taken only when needed. Take VIAGRA ABOUT 1 HOUR BEFORE SEXUAL ACTIVITY. However, you may take it between 30 minutes to 4 hours before sexual activity if needed. The drug can remain effective for between four and five hours. This does not mean that your erection will last that long – simply that you will have the ability to attain an improved erection for that period of time.
  4. 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.
  5. Do not take Viagra within twenty four hours of taking Sildenafil, Cialis or Levitra.
  6. After sex, your erection should go away. In the rare event of an erection lasting more than 4 hours, SEEK IMMEDIATE MEDICAL HELP to avoid long-term injury.
  7. 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 Viagra.
  8. VIAGRA DOES NOT PROTECT YOU OR YOUR PARTNER FROM GETTING SEXUALLY TRANSMITTED DISEASES, including HIV—the virus that causes AIDS.
  9. Grapefruit and grapefruit juice may interact with Viagra and lead to unwanted side effects. Avoid the use of grapefruit products while taking this medicine.
  10. Drinking alcohol can increase certain side effects of Viagra.
  11. Avoid using any other medicines to treat impotence, such as alprostadil or yohimbine, without first talking to your doctor.

Viagra is supplied as blue, film-coated, rounded-diamond-shaped tablets containing sildenafil citrate equivalent to 25 mg, 50 mg, or 100 mg of sildenafil. Some men may respond to a lower dose of Viagra. The doctor needs to decide which dosage of Viagra is most appropriate. The doctor will take into account potential drug interactions, your age, the severity of your erectile dysfunction and any previous experience you have had with Viagra. Viagra might not work the first time you take it. Most doctors advise taking Viagra at least eight times before trying a different medicine.

Important safety information

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

Do not take Viagra if you:

  • are allergic to sildenafil, as contained in VIAGRA and REVATIO or any of the ingredients in Viagra
  • take any other medicines called nitrates, often prescribed for chest pain, as this may cause a sudden, unsafe drop in blood pressure. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (“poppers”)
  • take 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
  • take medicines called HIV protease inhibitors, such as ritonavir (Norvir), indinavir sulfate (Crixivan), saquinavir (Fortovase or Invirase) or atazanavir sulfate (Reyataz)
  • take some types of oral antifungal medicines, such as ketoconazole (Nizoral) and itraconazole (Sporanox)
  • take some types of antibiotics, such as clarithromycin (Biaxin), telithromycin (Ketek) or erythromycin.
