Viagra and Lifestyle Interactions
Still, it's an interesting area of new research. A European study of 25 men who had erectile dysfunction but no other circulatory disorders found that blood vessels in the brain responded to stress better after a 50-mg dose of sildenafil. More interesting results were reported by scientists in Michigan, who produced ischemic strokes in rats by temporarily blocking blood vessels. During their recovery, the animals were divided into three groups. One received no treatment, another low-dose sildenafil, and the third high-dose sildenafil. The animals who got sildenafil recovered better, with the highest doses producing the best results. The scientists concluded that the medication actually stimulated the growth of new nerve cells in the brain tissue next to the stroke damage.
How oral medicines differ
And the FDA has approved sildenafil (Revatio) in a dose of 20 mg three times a day for men and women with pulmonary hypertension. Clinical trials have demonstrated improved exercise tolerance with few side effects. Pulmonary hypertension is a feature of acute mountain sickness. High altitudes produce low blood-oxygen levels. In turn, low oxygen produces a narrowing of the pulmonary arteries.
Sildenafil: what you need to know
The heart must therefore work harder, reducing the capacity to exercise. To find out if it might improve exercise capacity in low oxygen conditions, scientists tested 14 healthy mountain climbers in a lab in Germany and again at a Mount Everest base camp. In the lab, the volunteers breathed 10% oxygen through a mask; on the mountain, they breathed natural air. Under both conditions, a 50-mg sildenafil tablet decreased pressures in the lungs' blood vessels and increased the maximum exercise capacity. It's a small study, and it's too soon to say if sildenafil will help prevent or treat acute mountain sickness. It's generic viagra sildenafil citrate 50 mg far too early to know whether sildenafil may someday help people with strokes. If you get your information about sildenafil from Super Bowl commercials or e-mail spam, you might dismiss it as a lifestyle drug of little real medical importance. In fact, it's a serious prescription medication that has helped millions of men who are distressed by an entirely legitimate medical problem. Because the drug acts on arteries beyond the penis, it can produce various side effects. That means it should only be prescribed by a personal physician who really knows you. And it also means that scientists are investigating uses for the drug in patients with an array of vascular disorders having nothing to do with sexual function. They have nearly identical effects on ED as well as similar side effects. Because they are newer drugs, scientists are just beginning to study them for problems that don't involve sexuality. Sildenafil has already been licensed to treat men and women with pulmonary hypertension. Time will tell if any of these drugs will fill other potentials beyond promoting potency.

We do not endorse non-Cleveland Clinic products or services. The medication, officially known as sildenafil, debuted in 1998. Today, it’s used by millions of men around the world when they want to … well, rise to the occasion during an amorous moment. Yet myth-based questions continue to follow the little blue pill around. Can Viagra give you a never-ending erection? Let’s set the record straight with the help of urologist Drogo Montague, MD. Odds are you’ve seen a Viagra commercial and heard this warning: Seek immediate medical help for an erection lasting four or more hours. It’s an attention-grabbing piece of cautionary advice. But the situation that it addresses — a condition known as priapism — is a relatively uncommon side effect of the medication, says Dr. Montague.
Side effects
But since it's a serious problem, any benefit is most welcome. When we think of blood pressure, we usually think of the systemic circulation, of the blood pumped from the heart's left ventricle to the aorta and then to the smaller arteries that carry oxygen-rich blood throughout the body. But to pick up vital oxygen, blood must first pass from the less powerful right ventricle through the pulmonary artery to the lungs, then back to the left side of the heart. The pressures in the pulmonary artery are much lower (about 20/10 millimeters of mercury, or mm Hg) than in the aorta (lower than 120/80 mm Hg is considered healthy). Exercise is the most common cause of rising pulmonary artery pressure, but the elevation is mild and subsides promptly with rest.
How to Take Sildenafil
High altitudes are another cause, which can lead to mountain sickness (see below). Far more serious are the large number of lung diseases, vascular diseases, heart disorders, and miscellaneous conditions that can cause pulmonary hypertension. And in primary pulmonary hypertension, no underlying cause is evident. Pulmonary hypertension causes shortness of breath, first during exertion but eventually at rest if the condition progresses. A variety of treatments are available, depending on the underlying problem. A study published in 2020 categorized long-lasting erections from Viagra and other ED medications as a “rare event.” Researchers found 411 cases of drug-induced priapism while reviewing more than two decades worth of data.
1. What is Viagra?
Still, a study of 29 climbers reported that tadalafil can also reduce pulmonary artery pressure at a high altitude. In affected individuals, exposure to the cold triggers spasm of the small arteries that supply blood to the fingers, toes, or both. Temporarily deprived of adequate blood flow, the involved digits become pale, cold, and very painful. It's a common condition, affecting up to 8% of men and 17% of women. In the vast majority, there are no underlying diseases (primary Raynaud's), and patients do well simply by minimizing their exposure to cold.
Drug forms and administration
But secondary Raynaud's can complicate collagen-vascular diseases or certain other conditions. It's not common, but secondary Raynaud's can be very viagra gel painful and difficult to treat. Many medications have been used without consistent success. But a 2005 study of 16 patients with severe Raynaud's phenomenon that had not responded to other medications reported benefit from sildenafil in a dose of 50 mg twice a day. And a 2006 study of 40 Raynaud's patients reported similar benefits from vardenafil in a dose of 10 mg twice a day. But your odds of problematic prolonged erections increase if you combine Viagra with certain penile injection therapies, notes Dr.
Detection in biological fluids
Sildenafil was discovered by scientists looking for a new medication to dilate coronary arteries. It does that, but because it widens healthy coronary arteries more than diseased vessels, it has not been successful in treating angina. But it may have other benefits for cardiac patients. In the first years of the Viagra era, research on sildenafil and the heart was devoted to making sure the drug was safe for the circulation. In most men with heart disease, it is.
Altitude sickness
But several studies of patients with congestive heart failure also reported that the medication improves oxygen consumption, pulmonary artery pressure, and exercise capacity in these patients. Research shows that sildenafil helps the heart muscle relax properly, which could help patients with heart failure due to diastolic dysfunction. Another interesting property is sildenafil's ability to protect the heart from excessive stimulation by adrenaline. Clinical trials will be needed to see which patients might benefit. It's the most speculative use for sildenafil, and it's far from clinical application. Montague. “Combining the treatments has a cumulative effect — penile injection therapy makes your erections hard, and adding Viagra makes them harder and even more long-lasting,” he continues. “So stay on the safe side and don’t pair them.” Here’s a fun fact for you: Viagra was created to help your heart. Researchers initially developed Viagra to treat angina, a type of chest pain. Angina occurs when your heart doesn’t get enough oxygen-rich blood and starts working harder to compensate.
- Viagra can help improve the quality of your sexual relationship.
- People should inform their doctor about any allergies before use.
- Viagra is part of a broader class of medications called PDE5 inhibitors.
- Sexual desire is still necessary for Viagra to be effective.
- Regular health check-ups can monitor the effects of the medication.
- Some users report improved self-esteem with proper use.
- Proper hydration can help reduce side effects like headaches.
Now, Viagra didn’t exactly shine as a treatment for angina … but the stiffer erections the little blue pill caused certainly stood out as a side benefit.
- Viagra is available in various dosages, usually 25mg, 50mg, and 100mg.
- It is important to follow a healthcare provider’s dosage instructions.
- Viagra is not an aphrodisiac and requires sexual stimulation to work.
- The medication can be affected by certain foods, such as high-fat meals.
- Overuse can lead to increased side effects or reduced effectiveness.
- Do not take Viagra more than once within a 24-hour period.
- Consult a doctor if you experience persistent erections or pain.
Which brings us back to the question regarding Viagra and your heart. The erectile dysfunction medication isn’t harmful to your ticker when taken on its own. That’s an important caveat because Viagra should NOT be taken with heart medications that include nitrates. Like nitrates, Viagra helps dilate (or expand) blood vessels constricted by coronary artery disease. Your blood pressure drops when this happens, as less force is needed to pump blood through your system. The worry if you take both Viagra and nitrates is that your blood pressure could drop too low, a condition known as hypotension. Abnormally low blood pressure increases your risk of a heart attack or stroke. Talk to your healthcare provider before taking Viagra with other medications. Taking Viagra to enhance your bedroom performance likely won’t make it more difficult for you to see your partner — unless you overdo it. High doses of Viagra have been connected to temporary vision issues, reports the American Academy of Ophthalmology. But overall, the medication is considered low risk when it comes to eyesight. There’s a slight chance, though, that the pill may color your world blue for a bit.
