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:

Can a huge dental abcess harm my unborn baby?
Im 14 weeks pregnant and had a rough pregnancy so far (high risk due to Extrachrionic Haemorrhage and 8 previous miscarriages) and ive been put on antibiotics (Amoxycillin 500mg) and have been on them for about 3 months due to a small abcess (was on the waiting list for a dentist) I have been allocated a dentist and went to see them last week where i got told (as i suspected) that i needed to have a tooth extracted, this should of been done tomorrow, However this morning i woke up this morning with a huge lump on the right hand side of my face (looks like im smuggling golf balls!!) the infection has clearly spread. I have been back to my dentist this morning who have said i need to have my gum slit to release the infection and still have the tooth extracted. Anyways my appointment isn't for another week and i was wondering if this is ok or will the infection spread and harm baby? I know this sounds silly to ask but i dont know if it can
Thanks people - The Amoxycillin has been prescribed by both my Doctor and Dentist. As for a Gynacologist though i dont have one. Am in UK and have a midwife who has said that the tablets are ok to take too
What will happen if i postpone my root canal?
I was experiencing a severe pain in my tooth and went to see a dentist. The dentist recommended me a root canal and gave me some pain killers and Amoxycillin capsules 500mg. But I want to do the root canal in my home town in two months. What are the consequences of postponing the root canal treatment? Thanks.
Is there no problem taking amoxycillin 500mg while taking anti-hypertension drugs?
I am currently on medication to lower my blood pressure. I am taking losartan, atenolol and aspirin. Just recently, I have problem with my upper teeth (molar) and was given amoxycillin to stop the infection. I am working in the middle of the desert and what we have in the field is just a small clinic for emergency purposes only. Thanks.
First Time Taking LSA Risks, And Suggestions?
I really, really wanna try doing Hawaiin Baby Woodrose seeds (which has LSA in it) when going to Alice In Wonderland this next Friday.
I've never done any drugs outside of cannabis and alcohol (yeah I know, I'm a pussy) so this would be my first psychedelic experience. I just wanna now if I should try something else first, or if it's weak enough for a first timer to try. I know that you're supposed to take them slowly, or else you get a bad trip, and I've done a bit of digging on the internet to try to find out as much as I can. What I want to know is if it's possible to wash off pesticides, say if I decided to buy the seeds from Wal-Mart or a seed shop, where it's non-organic, or if I should just go the safe way and go with organic seeds, so that I don't end up in the hospital or something. I need to know this pretty soon here, because I need to know if I have to order some online or not and have them shipped here before Friday.
Do you feel you slowly go crazy living by yourself?
I have had 2 apartments so far in my life and I am only 21. It was nice living by myself but I felt I was slowly going crazy. I would rather have a roommate to keep me company but my friends in school were losers, huge pot heads that would rather buy drugs and live at home then try to make it in the world. I found a place that is targeted towards college kids where 4 people pay $400 a month for a 4 bed room furnished apartment. The bedrooms are small but the same size as my room at home, all I need to do there is sleep and study. They have a large living room and kitchen with 2 bathrooms. All my friends with apartments already say don't do it. I can live by myself with privacy for $400 a month plus utilities, at the place by school its $400 for everything. Is it bad that I don't care about privacy and would rather live with a group of people.
would you read my book??
i am thirteen but i do have plenty of curse words so... yeah. leave comments..
its called Decisions to Make
have you ever had a family that didnt want you? well right now my dad could care less if i lived today or died. my mom was too scared of my dad -on steroids and who knows how many other drugs- to do sh*t. you only want to go to schoolbecause you get away from your family. but then you realise people are starting rumors about you. Then waht you thought was a peaceful getawat only turns into a bigger hell than at home.Then someone you REALLY like asked you out. ofcorse you say yes then three weeks later he brakes up with you, and school only becomes a bigger pain in the ass.who am i? my names elizabeth walker. my friends just call me liz or lizzy.i am 21 years old.My mother died when i was 14. She drowned in a river near my grandma rozas gouse. after that i lived in foster homes because when we called the cops they examined my father and found serious drugs in his system such as cocaine weed and many other drugs then they took him to jail. so yeah i was living with fat families thin families big families small families sane families and crazy families. so my dating life was a living hell and my sex life didnt exist. even though my mom died i kept my promise"you can either stay a virgin until your married or moved out"she once said. "pinky swear mommy"i said, then we went to bed. that was my first talk about sex and i was only nine. But oh well. it made me smarter. She once told me that a guy would say anything to get you in bed. So when a guy told me he loved me i told him i wasnt sleeping with him. they`d try the next day i said no and they dumped me. on my 18th birthdaymy gramdma bought me a house in paris, close to hers. i got a boyfriend and an extremely handsome one at that. he was 17 and in colleage which was weird at the time but i overlooked it. one day we were talking "liz, we need somewhere else to live. maybe somewhere closer to school?" Justin said and thats all i got so far. not really but im getting tired so thats where im stopping. lol sorry.
