Sildenafil relaxes muscles and increases blood flow to particular areas of the body.
Sildenafil under the name Viagra is used to treat erectile dysfunction (impotence) in men. Another brand of sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women.
Sildenafil may also be used for purposes other than those listed here.
What should I discuss with my doctor before taking sildenafil?
Do not take sildenafil if you are also using a nitrate drug 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 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. This type of vision loss is caused by decreased blood flow to the optic nerve of the eye. 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.
Before taking sildenafil, tell your doctor if you have:
heart disease or heart rhythm problems;
a recent history (in the past 6 months) of a heart attack, stroke, or heart rhythm disorder;
congestive heart failure;
high or low blood pressure;
coronary artery disease;
liver disease;
kidney disease;
a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia;
a bleeding disorder such as hemophilia;
a stomach ulcer;
retinitis pigmentosa (an inherited condition of the eye);
a physical deformity of the penis (such as Peyronie's disease); or
if you have been told you should not have sexual intercourse for health reasons.
If you have any of these conditions, you may not be able to use sildenafil or you may need a dosage adjustment or special tests during treatment.
FDA pregnancy category B: This medication is not expected to be harmful to an unborn baby. Do not use sildenafil without telling your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known if sildenafil passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
How should I take sildenafil?
Take each dose with a full glass of water.
Avoid taking High-fat food before taking Viagra as it may cause the medicine to take more time to start working.
Sildenafil is usually taken only when needed, 30 - 90 minutes before sexual activity. The medication can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill.
Do not take sildenafil more than once a day. Allow 24 hours to pass between doses.
Store this medication at room temperature away from moisture and heat.
What happens if I miss a dose?
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. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention if you think you have used too much of this medicine. Symptoms of a sildenafil overdose may include chest pain, nausea, irregular heartbeat, and feeling light-headed or fainting.
What should I avoid while taking sildenafil?
Avoid drinking alcohol, which can increase some of the side effects of sildenafil.
Avoid using other medicines to treat impotence, such as alprostadil (Caverject, Muse, Edex) or yohimbine (Yocon, Yodoxin, others), without first talking to your doctor.
What are the possible side effects of sildenafil?
If you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw during sexual activity, stop and call your doctor right away. You could be having a serious side effect of sildenafil.
Stop using sildenafil and get emergency medical help if you have sudden vision loss.
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.
Continue taking sildenafil and talk with your doctor if you have any of these less serious side effects:
warmth or redness in your face, neck, or chest;
stuffy nose;
headache;
upset stomach; or
back pain.
Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
What drug(s) may interact with ?
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
Sildenafil may also interact with the following medications:

Will suboxone relieve pain ?
I have been taking opiod pain killers for almost 10 years. I never abused it though, I always took one pill every 4-6 hours no more than 4 a day. I started to realize 2 years ago that I was abusing it when moderate pain killers such as loratab vicodin ect. was no longer available and all I could find was morphine. It didn't take long before i knew I had a problem so I quit cold turkey. It was hell but I stopped and survived on aleive and sometimes my doctor would give me tramadol. But then I broke my feet and later had to have surgery and I was prescribed vicodin for a few months. Now I am buying them again illegally and I want my pain to be treated by a doctor but I can't afford the imaging that needs to be done and the visits to pain management. So if I go on suboxone and take alieve will that at least leave me comfortable and productive?

How to get rid of UTI without going to the dr?
I am positive I have a uti because i have had 3 in the past few months and I can't afford to go to the dr again for it. Are there any pills I can buy at a drug store or anything to get rid of this? Thanks!
is it illegal to buy this and will i be watched?
i want to buy bowls and bongs online because i want to collect them. i want the best and coolest to add to my collection and the headshops around me suck. im pretty sure its not illegal to buy bongs and bowls online (feel free to let me know if im right or not about this).
but i saw an anwer on yahoo answers from this guy that said if you buy things like that online then your name will go on a "possible drug users" list. and the more you buy the more the feds will be up your ***. is this true??
what if ONLY the government sold marijuana as if it were alcohol?
then the government would get 100% of the profits. it would just yknow, have to be sold in an honorable way since its the government. I was also thinking of extremely strictly selling cocaine too, because drugs are the the terrorists' money. if we remove their ability to sell drugs, what else will they have? the coke would have to be EXTREMELY controlled and monitored, so humans cant get addicted and its not suepr dangerous. like 2 highs, 2 weeks. it'd get ppl to buy it legally and 100% safely from the government. it'd get the $$ and the dealers would have to counter it somehow, if they could.
i like what you said ugly truth, but I mostly meant central american terrorists a.k.a. cartels. and some taliban heroine comes through america too.

Why husband masturbates instead of having sex with wife?
Ok, so my husband has not had sex with me for a long time. When he does, he doesn't seem to enjoy it. Supposedly he can't have an erection so he uses Cialis or Viagra in order to have sex with me so whenever I show some initiative he rejects me and says he can't do it. He is 45 and currently under a lot of stress. My sexual frustration leads to arguments so he says he doesn't feel "sexy". But he admits he masturbates and I think he does it regularly. I haven't seen him do it so have no idea what turns him on cause he won't tell me anything. Moreover, he never climaxed in my presence and he doesn't like talking about this. When I ask him about having children, his standards answer is "It's not the right time now. I love you and we'll figure something out." What's going on? How can I find out the truth? This situation drives me crazy. Perhaps we should go to a doctor? What kind of doctor? Any ideas?
erection problems (?) at 19?
hey everyone, I want some opinions on the (possible?) issue I am facing.. I became sexually active about 4 months ago. me and my girlfriend are both 19. when we began I was taking finasteride (propecia) prescribed by my dermatologist for preventing the hereditary hairloss that seems to start with all the guys in my family around this age. the first time we had sex I noticed I wasn't as hard as I've been before. and after we had sex once I was just hard enough to have sex a second time. I emailed a doctor online and he said to discontinue use of propecia. so I did. after that I was able to go twice without a problem. my only concern is the refractory period between. I hear the average for guys my age is 15 mins...
I usually take about 45 mins before I can get hard again.
and if I ever go a third time we end up waiting an hour or more... I have emailed a few doctors the same thing... well, maybe a little more in depth. and 2 said it's normal, 1 said to go to a urologist because it's abnormal..... anyone have any advice? anyone have the same problem? thanks everyone!
haha
thanks TX
