Viagra Patient Tips

ED pills are quite safe for men with stable cardiovascular disease who do not take nitrates.

3. How does Viagra work?

Sildenafil was the first effective oral medication for ED. Although there are some differences between these drugs (vardenafil starts working sooner and tadalafil works longer), they all act in exactly the same way to combat ED. The three drugs are so similar because they share a common target, an enzyme called phosphodiesterase-5 (PDE-5). To understand why blocking PDE-5 improves sexual function, however, you have to know how erections develop. Normal erections require a receptive state of mind, adequate levels of testosterone, and healthy arteries, veins, and nerves.

Sildenafil may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

But they also require a tiny chemical messenger called nitric oxide (NO). It serves two crucial functions: transmitting the impulses of arousal between nerves and relaxing the smooth muscle cells in the arteries, allowing them to widen and admit more blood to the penis. Nitric oxide is essential because it signals the arterial cells to produce cyclic guanosine monophosphate (cGMP), the chemical that increases the flow of blood to the penis. But the tissues of the penis also produce PDE-5, the enzyme that breaks down cGMP. In normal circumstances, the penis generates enough cGMP to produce a rigid erection and enough PDE-5 to end the erection when ejaculation is complete.

1. Don’t eat a heavy meal beforehand

In many men with ED, this intricate system is out of balance, but one of the three oral medications can often make it right. By inhibiting PDE-5, they increase the supply of cGMP, which for many men will allow erections to develop. In test tubes, vardenafil and tadalafil inhibit PDE-5 a bit more effectively than sildenafil does. But laboratory potency doesn't necessarily predict clinical activity. In this case, it means that lower doses of the newer drugs will achieve comparable results to the older drug's success rate. This group includes patients with stable angina, previous heart attacks, mild congestive heart failure, well-controlled hypertension, and previous strokes.

• Men should start with the lowest effective dose recommended by their doctor.
• It can take several weeks to notice full benefits of daily Viagra.
• Proper hydration and healthy lifestyle habits support treatment.
• Men should avoid high-fat meals around the time of taking Viagra.
• It is important to disclose all medications and health issues to your doctor.
• Viagra daily does not cause addiction but requires responsible use.
• Psychological factors may still influence the effectiveness.
• Combining Viagra with other lifestyle changes enhances overall results.

But men with recent heart attacks and strokes should wait until they have recovered fully, and patients with unstable blood pressure, active angina, or any other complex or unusual problem should hold off and get specific medical guidance.

And men who take alpha blockers (particularly terazosin, or Hytrin, and doxazosin, or Cardura) for hypertension or benign prostatic hyperplasia (BPH) should use ED pills (particularly vardenafil or tadalafil) with great caution, if at all. Studies also suggest that sildenafil may increase respiratory distress in men with severe sleep apnea and that it slows gallbladder function, which might increase the risk of gallstones.

Interactions between Sildenafil (Viagra) and other drugs

Nitrates are medications that temporarily widen arteries by increasing their supply of nitric oxide. That's how they widen partially blocked coronary arteries in patients with angina. But because the nitrates and ED pills all act on nitric oxide, they do not mix. Men who are taking nitrates should never use any of the ED pills. This ban includes all preparations of nitroglycerin (short-acting, under-the-tongue tablets or sprays); long-acting nitrates (isosorbide dinitrate, or Isordil, Sorbitrate, and others, and isosorbide mononitrate, Imdur, ISMO, and others); nitroglycerin patches and pastes; and amyl nitrite (so-called poppers, used for sexual stimulation by some men). Scientists who noticed that the ED pills can produce side effects in many parts of the body are asking if they can also serve therapeutic roles beyond male (or female) sexuality.

Before Using

In almost every case, these side effects are mild and transient. But new information has added a rare eye disease to the list. Nonarteritic anterior ischemic optic neuropathy (NAION) is a poorly understood disorder that can cause blindness. In March 2005, doctors reported that seven men experienced visual impairment within hours of using sildenafil. Since then, additional cases have been reported to the FDA related to sildenafil, tadalafil, and vardenafil.

Eat a light meal beforehand

Fortunately, the number of cases is very small in relation to the millions of men who have used ED pills successfully. It's not clear that there viagra click and collect is a cause-and-effect relationship between ED pills and NAION. At present, the concern is not great enough to prevent men from using these pills, but all men should use them carefully and responsibly. The most important worry about ED pills is their ability to widen arteries enough to lower blood pressure. It's rarely a problem in healthy men, but it explains a crucial precaution that applies to all three medications. Because of its seniority, most of the research has used sildenafil, so it's not clear if the newer medications will fill similar roles. But for sildenafil, at least, some new uses appear promising. It's the only nonsexual condition that has earned FDA approval for sildenafil.

• Remember that Viagra does not protect against sexually transmitted diseases.
• Use contraception if necessary, as Viagra does not affect fertility.
• Alcohol consumption can diminish Viagra's effects.
• Always follow the prescribed instructions carefully.
• Viagra is most effective when taken on an empty stomach or with light food.
• Lifestyle factors like smoking can impact its effectiveness.
• Not suitable for men with severe liver or kidney conditions.
• Open communication with your healthcare provider optimizes treatment.

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. 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.

• Viagra daily can improve erectile function with regular use.
• Consistency is key for Viagra daily to be effective.
• Consult a doctor before starting daily Viagra use.
• Viagra daily may have fewer side effects than on-demand use.
• Taking Viagra daily can help manage ongoing erectile issues.
• The typical dose for daily Viagra is lower than as-needed doses.
• Daily Viagra may improve confidence and performance.
• It is important to follow prescribed dosing when using daily Viagra.

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. 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. 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.

Age Group	Proportion Taking Daily Viagra (%)	Common Reasons
30–40	10%	Performance anxiety, early ED
40–50	30%	Declining sexual function
50–60	40%	Chronic health issues, aging
60+	20%	Age-related ED, cardiovascular issues

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. 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.

• Viagra daily is primarily prescribed for men with ongoing erectile difficulties.
• It may lead to improved general well-being and sexual satisfaction.
• Points of caution include potential hypotension or dizziness.
• Use caution when engaging in activities requiring alertness.
• A balanced diet supports overall medication effectiveness.
• Notify your healthcare provider if you experience chest pain or vision changes.
• Use as part of a comprehensive treatment, including counseling if needed.
• Do not share medication with others and keep out of reach of children.

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. But secondary Raynaud's can complicate collagen-vascular diseases or certain other conditions. It's not common, but secondary Raynaud's can be very painful and difficult to treat. Many medications have been used without consistent success.

More about Viagra (sildenafil)

Vardenafil is marketed in 2.5-, 5-, 10-, and 20-milligram (mg) tablets; tadalafil in doses of 5, 10, and 20 mg; and sildenafil, 25, 50, and 100 mg. Each produces better results at higher doses, but the top doses are also more likely to cause side effects. And all the drugs are more effective in men with mild ED than in those who are severely impaired. Doctors have had more clinical experience with sildenafil than its newer rivals. Still, all three drugs seem to achieve similar results.

Key takeaways

In broad terms, about 70% of men benefit. The response is best in men with no identifiable organic cause of ED (about 90%), but it's less favorable for diabetics (about 50%), and it's hard to predict for men who have been treated for prostate cancer. If PDE-5 were found exclusively in the penis, the side effects of these drugs would be limited to that obdurate organ; in fact, a rare side effect is priapism, painful prolonged erections that require urgent treatment. But small amounts of PDE-5 are found in blood vessels in other parts of the body. In addition, PDE-5 is just one of 11 enzymes in the phosphodiesterase family.

Improves quality of life

The others are concentrated in different parts of the body. While the ED pills have a much greater affinity for PDE-5 than the other PDEs, they have some ability to inhibit those closely related enzymes. Both factors explain why the ED pills sometimes produce side effects in many parts of the body. The most common side effects are headaches and facial flushing, which occur in about 15% of men. Other reactions include nasal congestion, indigestion, and back pain; blue-tinged vision is even less common. 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.

Sildenafil was discovered by scientists looking for a new medication to dilate coronary arteries.

Condition	Risk Level	Recommended Action
Severe Heart Disease	High	Consult doctor before use
Nitrate medication use	Very High	Do not take Viagra without medical approval
Liver impairment	Moderate	Dose adjustment or avoid use
Vision loss (NAION)	High	Avoid or consult healthcare professional

It does that, but because it widens healthy coronary arteries more than diseased vessels, it has not been successful in treating angina.
