Why is Viagra prescribed? Viagra is an oral drug for male impotence, also known as erectile dysfunction (ED). It works by dilating blood vessels in the penis, allowing the inflow of blood needed for an erection. Viagra causes erections only during sexual excitement. It does not work in the absence of arousal. How should you take Viagra? 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. --If you miss a dose... for regular use. Take it only before sexual activity. --Storage instructions... Store at room temperature. What side effects may occur? Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Viagra. Abnormal vision (color tinge, blurring, sensitivity to light), acid indigestion, diarrhea, flushing, headache, nasal congestion, urinary tract infection Heart attack, stroke, heart irregularities, dangerous surges in blood pressure, and sudden death have all been reported after use of Viagra, usually in men with existing cardiac risk factors, and typically during or shortly after sex. Why should Viagra not be prescribed? 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. If Viagra gives you an allergic reaction, do not use it again. If you have heart problems severe enough to make sexual activity a danger, you should avoid using Viagra. Use it cautiously--if at all--if you've had a heart attack, stroke, or life-threatening heart irregularities within the past 6 months. Be equally cautious if you have severe high or low blood pressure, heart failure, or unstable angina (crushing heart pain that occurs at any time). If you take Viagra and develop cardiac symptoms (for example, dizziness, nausea, and chest pain) during sexual activity, do not continue. Alert your doctor to the problem as soon as possible. If you have a condition that might result in long-lasting erections, such as sickle cell anemia, multiple myeloma (a disease of the bone marrow), or leukemia, use Viagra with caution. Also use cautiously if you have a genital problem or deformity such as Peyronie's disease. If an erection lasts more than 4 hours, seek treatment immediately. Permanent damage and impotence could result. If you have a bleeding disorder, a stomach ulcer, or the inherited eye condition known as retinitis pigmentosa, use Viagra with caution. Its safety under these circumstances has not yet been studied. To avoid low blood pressure, do not take the 50-milligram or 100-milligram dose of Viagra within 4 hours of taking an alpha-blocking drug such as Cardura. Remember that Viagra offers no protection from transmission of sexually transmitted diseases, such as HIV, the virus that causes AIDS. If Viagra is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Viagra with the following: Erythromycin (E-Mycin, Ery-Tab, PCE) Nitrates such as Isordil, Nitro-Bid, and Nitro-Dur Rifampin (Rifadin, Rimactane) Saquinavir (Fortovase, Invirase) Viagra should not be used by women. Its affects during pregnancy and breastfeeding have not been studied. Doses range from 25 milligrams to 100 milligrams, depending on the drug's effect. The usual dose is 50 milligrams. If you are over 65, have liver or kidney problems, or are taking erythromycin, ketoconazole, itraconazole, ritonavir, or saquinavir a dose of 25 milligrams may be sufficient. Your doctor will adjust the dosage if the drug is not working properly for you. Take Viagra only before sexual activity. The manufacturer recommends a maximum of 1 dose per day (1 dose every 2 days for those taking ritonavir). To avoid low blood pressure, do not take the 50-milligram or 100-milligram dose of Viagra within 4 hours of taking an alpha-blocking drug such as Cardura. No overdose of Viagra has been reported. However, any medication taken in excess can have serious consequences. If you suspect an overdose, seek medical attention immediately. cheap herbal viagra Should I Confront My Wife About Affair? TEN years ago I fell in love with a girl. She was 22 years younger than me and I was married. But the love I felt for her then - and still do - was overwhelming. So I left my wife for her. It was messy and my two grown-up children made it clear they wanted nothing to do with me after what I had done to their mum. I felt guilty but the dust settled and after the divorce I married my second wife. It was the happiest day of my life. We now have an eight-year-old and I've managed to patch things up with the older ones. My wife is 37 and I'll be 60 this year. The problem is I have been having trouble sustaining an erection. I'm taking Viagra which helps, but I don't have the same energy I used to have. I'm almost certain my wife is having an affair. We had a young guy, in his twenties, help get the garden in our new house into shape and I could see he was attracted to her. She's still an amazing-looking woman and doesn't look a year older than when I first saw her. She's been getting texts which she deletes immediately and I know for a fact when she told me she was round at her mum's that it was a lie. So I'm worried sick. I know I should tackle her about what's going on but I can't. I can't live without her and I don't like the thought of my ex-wife, most of my friends and my relatives pointing out that they all told me the age gap was too big and we wouldn't last. OF course you could carry on as you are with your head buried in the sand. There is the possibility your wife isn't having an affair or even if she is, it isn't serious and will soon blow itself out. Your problem keeping an erection could be affecting self-confidence and putting your imagination into overdrive. In some ways, sitting tight might be the sensible thing to do, especially as you have a young child but no intention of ending the marriage. But I don't think you can live with the uncertainty forever. Maybe you should give yourself a deadline of a few months. If you remain suspicious or get more solid evidence, I don't believe you can go on ignoring the issue. If she wants to save the marriage, counselling through Relate Scotland or Scottish Marriage Care is the next step. But if things can't be fixed, there's no point trying to glue it together just because you don't want those who warned you against marrying a younger woman crowing. If you have a problem, write to: Just Joan, Daily Record, One Central Quay, Glasgow G3 8DA or email j.burnie@dailyrecord.co.uk. I cannot reply personally. generic name viagra
The most widely used remedy for erectile dysfunction; research has indicated that Viagra has an effect on the condition of the human heart as well as a male's penis. The hormonal stress normally exerted on the human heart has been noted to be decreased in men who take Viagra. When conducted with mice, the testing was more noticeable, Viagra having the tendency to avert harmful and long term effects of chronic hypertension on their heart. The study, lead by the John Hopkins research team, found that there is potential benefits for the treatment of pulmonary hypertension, linked in with how Viagra dilates genital blood vessels. Viagra works by dulling the heart beat, which is increased during stress. It works to decrease the force which is needed to pump blood from the heart to the rest of the body. The research conducted by David Kass, cardiologist and senior researcher of the John Hopkins study noticed Viagra can be effective in blocking short- term consequences of hormonal stresses in the heart. Further evidence on the testing of mice (although further research is needed until this is applicable to humans), indicated that negative effects of heart failure and cardiac hypertrophy on weakened heart muscles can be reversed. Further research is need in this area on humans however. Thirty five men and women were tested and injected with Dobutamine (a synthetic derivative of dopamine that increases heart rate and contractions), which resulted in increased rate of 150%. The men and women were then separated into two groups, one of which were given sildenafil (Viagra) and the other given a placebo (fake) pill. Results showed that the first group's heart rate decreased by 50%, whilst the latter group's further increased. This has led to widespread scientific interest in the effects of sildenafil (Viagra) on the human heart condition. discount sildenafil generic viagra Levitra and Viagra are different drugs used to treat one common issue, Erectile Dysfunction (impotence). There are lots of similarities as well as differences when looking at Levitra vs. Viagra. Advice from your health care provider is the ideal way to conclude which drug is the perfect choice for treating your ED. One should never diagnose and treat ED on their own; it could turn out to be a life threatening move. It is mandatory for men with ED to understand the fact that they are not alone. As a matter of fact, millions of men all over the world suffer from ED each year. Fortunately, advancement in pharmaceutical technology has offered choices for these millions. When comparing Levitra with Viagra, the main point of difference is the main ingredient. While Levitra’s main ingredient consists of vardenfil, a PDE5 inhibitor, the main ingredient in Viagra is sildenafil citrate, which has been used not only to treat ED, but also pulmonary arterial hypertension Side effects arising from the use of vardenfil are: abdominal pain, back pain, photosensitivity, abnormal vision, eye pain, facial edema, hypertension, palpitation, tachycardia, arthralgia, myalgia, rash, itch, priapism, and in a few rare scenarios heart attack. Vardenfil should also not be taken if the patient is using any sort of nitrate medication. This is because it has the tendency to produce very low blood pressure. Health care providers will never prescribe Levitra to a patient at risk of experiencing serious side effects. Viagra was the first pill to be introduced to the market. Side effects of Viagra include: priapism, severe hypotension, myocardial infarction, ventricular arrhythmias, sudden death, stroke and enhanced intraocular pressure. The common side effects consist of sneezing, headache, flushing, dyspepsia, prolonged erections, palpitations, and photophobia. Visual changes including blurring of vision and a curious bluish tinge which have been reported in studies. Levitra and Viagra are nearly identical in that they are to be consumed anywhere from a half an hour to a couple of hours prior to sexual activity. Viagra may have been the starting point in the treatment of ED, but there is no doubt that Levitra has been seen as “new and better”. Levitra’s side effects are far and few versus Viagra, though response of drugs varies from person to person. A detailed analysis of your medical history is required to choose the ideal prescription drug for you. Nuts, crocodiles and witch trials may seem to have little to do with Viagra -- but at one time or another, they've all been employed against erectile dysfunction. For centuries, doctors struggled to pinpoint the causes of male impotence, blaming such factors as stress, diet, the wrath of deities and unattractive women. Ancient Greek physician Hippocrates attributed impotence to horseback riding; one of his contemporaries placed the blame on childhood trauma; Egyptians to evil spells. The ancients also left behind an imaginative array of remedies: snacks of almonds, pistachios, dates, currant juice and bird eggs in Persia; a mix of sesame, lentils, rice and sugar cane juice in ancient India -- or goat testicles boiled in milk or butter and boiled alligator testes rubbed on the feet. The Egyptians were more direct, smearing remedies (such as crocodile hearts and wood oil) directly on the penis. In the Islamic empire, impotence was sometimes blamed on an imbalance in the four fluids, or humors, thought to course through the body. Doctors advised men to avoid sex after meals, in the bathroom and with old or unappealing partners. In medieval Europe, impotent men believed they were under spells cast by witches, but also blamed their wives. Impotence was grounds for divorce. In the Victorian era, many thought impotence was due to a depletion of sperm. Doctors cautioned against masturbation (a "waste" of sperm) and prescribed quinine, opium, digitalis and bleeding, to no avail. In the late 1800s, French professor of medicine Charles Edouard Brown-Sequard proposed that injections of animal sperm might restore vitality. He tested the theory by injecting himself with an extract of dog and guinea pig testicles. His colleagues, who agreed the professor looked good for a man of 72, agreed to test the extracts on their patients. Soon the treatment, organotherapy, was all the rage. Starting in the late 1910s, a few doctors went a step further, deciding to transplant whole testicles. In France, Serge Voronoff transplanted monkey testicles into the nether regions of more than 1,000 old men. In Kansas, John Brinkley ran a hospital that specialized in grafting goat testicles onto patients. At a California prison, Leo Stanley gave older inmates testicles of younger, executed prisoners. Although many men claimed to feel rejuvenated by their testicular shots and transplants, few recovered their virility, and researchers continued their search. In the 1930s doctors experimented with surgical adjustment of penile muscles. In the 1940s and 1950s, they tried implants, inspired by the penile bones many animals have. In the 1960s, an effective option finally arrived. A Georgia tire serviceman began work on a vacuum pump to treat his own impotence, which was ultimately approved by the Food and Drug Administration in 1982. The pump appeared just as several researchers began to identify drug treatments for impotence, albeit few with the showmanship exhibited by British doctor Giles Brindley. At a 1983 urology meeting, Brindley injected himself with a drug, phentolamine -- then took the stage, dropped his pants and shared his erection with his colleagues. Brindley injected 33 drugs in his penis before finding one that worked, which may have rendered him slightly envious of the discoverers of Viagra. British researchers Ian Osterloh and Gill Samuels were developing a drug to improve blood flow to the heart when they realized that the drug, sildenafil citrate, was much more effective at improving blood flow to the penis -- and causing erections. In Viagra's first month on the market, doctors wrote well over 500,000 prescriptions. Considering men's history of options -- crocodile hearts, prayer, testicular shots and grafts -- perhaps the blue pill's lasting popularity should come as no surprise. comparison study of viagra cialis levitra Revatio, Viagra What is Viagra?

It is a topic fraught with hidden currents, treacherous shallows and wide meanderings. Viagra, the little blue pill has given a new life to the treatment of impotence and has a significant bearing on men who are suffering from erectile dysfunction. It is worth noting that just finding a "quick fix" for impotence does not overcome other issues that may have been the cause of the dysfunction before treatment began. Overcoming impotence often gives men unrealistic expectations about their ability to instantly come over their emotional as well as physical problems. For most men, their ability to get an erection and have sex is considered as a important part of their masculinity and potency. It is no surprise that the onset of impotence, even when due to underlying physical condition, can lead to psychological issues that increase the problem of impotence. Generally speaking, performance anxiety is a very real problem for many men. In other words, the fear of not being able to perform, dissatisfaction with penis size and self-consciousness about body appearance can all lead to the thing that most men do not want even in their dreams: failure to get an erection. Most men have an occasional episode of impotence due to anxiety. If erectile dysfunction has been there for considerable amount of time, this anxiety is multiplied. From a physiological point of view, anxiety can effectively prevent a man from becoming aroused and maintaining an erection. All the psychological issues seem to disappear with the help of Viagra, which is why it is the most effective and most prescribed erectile dysfunction treatment on the market. There is no reason to feel awkward if you are having issues getting an erection. Just remember that erectile dysfunction is a common problem and can happen to anyone of any age. When you take Viagra for the first time it provides harder erections and plays a prominent role in maintaining the erection for a longer period of time during sex. As Viagra has been proven safe to use in men who are suffering from heart problems, high cholesterol, diabetes, high blood pressure, prostate problems as well as spinal injury you feel at ease when using it. The best part about Viagra is that it works when you want it to. Studies have shown that it works for most men in as little as fourteen minutes, on average within half an hour, and makes it’s presence felt for at least four hours. viagra cialis generic What is Viagra used for?

When Pfizer released Viagra in 1998, they revolutionized oral medical management for erectile dysfunction. Along with its rival medications Cialis and Levitra, Viagra has become a popular drug of choice against impotence. However, anti - impotence drugs are not just used by older men anymore. A growing number of men under the age of 55 are using the â€?blockbuster pill'. A study of more than 5 million insured adults in 1998 to 2002 found that the fastest - growing segments of Viagra users were aged 18 to 55. These finding suggest use of Viagra not only as anti - impotence drug but as enhancement or recreational agent. How does anti - impotence pills like Viagra work? These drugs dilate blood vessels in the genital region leading to an increased blood flow and consequently, erection. However, it does very little to libido, sensation and sensuality. The effects of Viagra are noticed after an hour of taking the pill and the ease of erection lasts up to 12 hours. There may be side effects however such as headaches, flushes, nasal congestion or runny nose, malaise, changes in blood pressure, nausea, irregular heartbeats, and chest pain. Furthermore, anti - impotence drugs such as Viagra and Cialis increases the risk of vision loss in impotent men who have a history of hypertension and heart failure. Results of a study conducted by scientists at the University of Alabama in Birmingham showed that men who suffered heart attack were 10 times more likely to have optic nerve damage if they had been taking anti - impotence pills. Dr. Gerald McGwin, the one who headed the study, observed that there is a strong and statistically significant association between the use of Viagra and/or Cialis and non - anteritic anterior ischaemic optic neuropathy (NAION). NAION is the most common cause of acute optic nerve damage for people over 50 years old. It can cause the loss of vision in one or both eyes. There are also other impotent pills in the market which the Food and Drug Administration (FDA) warns the public about. These products, usually available through the internet, illegally contain the same ingredients as the prescription medicines approved by the FDA. Some of the product names listed by FDA are Zimaxx, Libidus, Neophase, Nasutra, Vigor - 25, Actra - Rx, and 4Everon. Tests showed that these products either contain sildenafil, the active ingredient in Viagra, or valdenafil, the active ingredient in Levitra. Dr. Steven Galson, Director of FDA's Center for Drug and Evaluation and Research, warns that these products threaten the public health because they contain undeclared chemicals similar or identical to the ingredients used in prescription medicines approved by the FDA. Furthermore, because you do not have to consult a doctor to buy this, you may not be aware that these ingredients can have dangerous interactions with drugs prescribed for heart disease, and may dangerously lower your blood pressure. buy viagra prescription online HE is only two, but Oliver Sherwood regularly takes Viagra - to keep him alive. The toddler has a rare condition that causes chronic high blood pressure. Something as simple a chest infection could kill him. The pulmonary hypertension, as it is known, can be controlled with four doses of Viagra a day. The drug improves blood flow, which in adults can boost erectile function but in rare cases such as Oliver's can open the veins and capillaries to aid circulation. His mother Sarah, a part-time nurse, said: "We joke when we pick up his drugs that it would be Christmas come early for most people. Obviously the dose isn't high enough to have the effect it would on adults. "Viagra is an expensive drug but it's actually one of the cheapest to treat pulmonary hypertension. "We're just hoping it'll continue to work as he grows a bit older." But Oliver's future could be in doubt because other drugs he could use as he gets older might no longer be funded by the Health Service. Pulmonary hypertension causes the blood pressure in the arteries in the lungs to rise, straining the heart and reducing blood oxygen levels, causing breathlessness and exhaustion. Symptoms include severe coughing and breathing problems as blood fills the lungs, constant nose bleeds, dizziness and chest pains. The condition, which affects 4,000 in Britain, often leads to heart failure. It is so rare that only five children a year are diagnosed with it in the UK. The survival rate is around five years, even with medication such as Oliver, who cannot walk more than a few steps without getting out of breath, takes one tablet of Sildenafil crushed into four 5ml doses a day. Doctors can increase the dose when his condition worsens, but there is no way of telling how much longer the drugs will be effective. As he grows up he will need to switch to more expensive treatments called Epoprostenol and Iloprost to control his condition. But the Government's drug rationing agency, the National Institute for Health and Clinical Excellence, is considering whether to continue prescribing them. Oliver's mother has started a petition calling for the Health Service to keep funding the treatments. Mrs Sherwood, 34, of Hucclecote, Gloucestershire, said: "The only hope we had was that he would be maintained through medication but if anything-happens in the future that hope may be taken away." The Pulmonary Hypertension Association said: "The clinical evidence for this is unfounded and it must be assumed it is based on cost alone." A spokesman for NICE added: "Our review of the evidence suggests that Sildenafil is both clinically effective and cost-effective in treating pulmonary arterial hypertension." |
