The penis is one of the areas where these enzymes work. Sildenafil is used to treat men who have erectile dysfunction (also called sexual impotence). By controlling the enzyme phosphodiesterase, sildenafil helps to maintain an erection that is produced when the penis is stroked. Viagra Soft tabs have the same active ingredient that Regular Viagra has but Soft tabs are specially formulated to be dissolvable under the tongue. Viagra is an oral drug for male impotence, also known as erectile dysfunction (ED). The pill is absorbed at the mouth and enters the bloodstream directly instead of going through the stomach.

Viagra causes erections only during sexual excitement. Taking sildenafil with a nitrate medicine can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack. A small number of patients have had a sudden loss of eyesight after taking sildenafil. It is not clear whether sildenafil is the actual cause of such vision loss. Sudden vision loss with sildenafil use has occurred most often in people with 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.
In combination with sexual stimulation, sildenafil works by helping the blood flow into the penis to achieve and maintain an erection. This drug is not indicated for use in women. Sildenafil is used to treat male sexual function problems (impotence or erectile dysfunction) by blocking a certain enzyme (phosphodiesterase-PDE5) in the body. Use of this drug does not protect against sexually transmitted diseases. Sildenafil soft is usually taken only when needed, 15 - 20 minutes before sexual activity. The medication can help achieve an erection when sexual stimulation occurs. Take it only before sexual activity. Put the pill under the tongue and wait till it desolves. If you miss a dose... Viagra is not for regular use. Taking Viagra approximately 1 hour before sexual activity works best for most men. Depending on how and when the drug works for you, an interval of one-half hour to as much as 4 hours may prove ideal. An erection will not occur just by taking a pill.
If any develop or change in intensity, inform your doctor as soon as possible. Side effects cannot be anticipated. Only your doctor can determine if it is safe for you to continue taking Viagra. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Viagra is used as needed, so you are not likely to miss a dose. If you miss a dose of Revatio, take the missed dose as soon as you remember.
Seek emergency medical attention if you think you have used too much of this medicine. Do not take Viagra if you are taking any nitrate-based drug, including nitroglycerin patches (Nitro-Dur, Transderm-Nitro), nitroglycerin ointment (Nitro-Bid, Nitrol), nitroglycerin pills (Nitro-Bid, Nitrostat), and isosorbide pills (Dilatrate-SR, Isordil, Sorbitrate). Combining Viagra with these drugs can cause a severe drop in blood pressure.
Sexual activity may put extra strain on your heart, especially if you have heart problems. If you have heart problems and experience any of these serious side effects while having sex, stop and seek immediate medical attention: severe dizziness fainting chest pain nausea For males, in the very unlikely event you have a painful or prolonged erection lasting 4 or more hours, stop using this drug and seek immediate medical attention, or permanent problems could occur. Rarely, sildenafil may cause sudden hearing problems, or ringing in the ears. Seek immediate medical attention if these effects occur. Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop using sildenafil and call your doctor at once if you have any of these serious side effects: chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, general ill feeling; irregular heartbeat; swelling in your hands, ankles, or feet; shortness of breath; vision changes; feeling light-headed, fainting; or, penis erection that is painful or lasts 4 hours or longer. If you have heart problems severe enough to make sexual activity a danger, you should avoid using Viagra.
Sildenafil may also interact with the following medications: alpha blockers, used for high blood pressure or an enlarged prostate. NOTE: Do not take doses of sildenafil higher than 25 mg within 4 hours of taking alpha blockers, such as alfuzosin (UroXatral), doxazosin (Cardura), prazosin (Minipress), or terazosin (Hytrin). If Viagra is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Do not take sildenafil if you are taking the following medications: nitroglycerin-type drugs for the heart or chest pain such as amyl nitrite, isosorbide dinitrate, isosorbide mononitrate, nitroglycerin, even if these are only taken occasionally.
