Overdose/Missed Dose

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. 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.

How does Viagra work?

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. 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.

What are the most common side effects of sildenafil?

In most men with heart disease, it is. 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. Or they may have you continue taking the 50-mg dose. You’ll continue to take Viagra only as needed. The maximum dosage is once per day.

2.5 Dosage Adjustments in Special Populations

It's the most speculative use for sildenafil, and it's far from clinical application. 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.

How Viagra Works

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. It's 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.

Viagra form

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. If you’re interested in a once-daily treatment for ED, such as tadalafil (Cialis), talk with your doctor. For most people, the maximum recommended dosage of Viagra is 100 mg once per day. This dosage may be too high for people who have certain medical conditions or take certain medications.

Why is this medication prescribed?

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.

How is sildenafil supplied (dosage forms)?

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. Under both conditions, a 50-mg sildenafil tablet decreased pressures in the lungs' blood vessels and increased the maximum exercise capacity.

Factors that affect how long Viagra lasts

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. It's a common condition, affecting up to 8% of men and 17% of women. So it’s important not to take more Viagra than your doctor prescribes for you. If your current dosage isn’t working well for your ED, talk with your doctor about increasing your dosage. Yes, Viagra is typically used as needed for ED. If you and your doctor determine that Viagra is safe and effective for you, you’ll likely use it as long as you have ED. A lower dosage of Viagra is safer for some people. This is typically due to certain factors, such as having specific medical conditions. taking a certain type of drug called an alpha-blocker that treats high blood pressure or prostate disease, such as tamsulosin (Flomax), doxazosin (Cardura), or prazosin (Minipress) If any of the above factors apply to you, talk with your doctor. They may lower your dosage to 25 mg of Viagra, instead of 50 mg. Note: Your doctor won’t prescribe Viagra if you’re taking a nitrate drug. Taking these drugs together can result in dangerously low blood pressure.

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

Examples of nitrates include nitroglycerin (Nitromist, Nitro-Dur, Nitrolingual Pumpspray, Gonitro, others), isosorbide mononitrate (Monoket), and isosorbide dinitrate (Dilatrate SR, Isordil). The typical starting dose of Viagra is 50 mg. But your doctor might prescribe a lower starting dosage of 25 mg, depending on several factors.

Dose (mg)	Frequency per Day	Effect Duration (hours)	Side Effects Possible
25	Once	4–6	Mild headache, flushing
50	Once	4–6	Dizziness, nasal congestion
75	Once	4–6	Heartburn, back pain
100	Once	4–6	Visual disturbances, nausea

Be sure to follow your doctor’s dosing instructions. For example, if you have liver or kidney problems, or if you’re taking certain other medications, your doctor might recommend starting with a 25 mg dosage. A 25-mg starting dosage may also be recommended if you’re 65 years or older. See “Dosage adjustments” just above for details about when a lower dose might be prescribed.

4. Bottom Line

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. As a service to our readers, Harvard Health Publishing provides access to our library of archived content. (An active ingredient is what makes a drug work.) Viagra belongs to a group of drugs called phosphodiesterase 5 (PDE5) inhibitors.

Is Viagra dosage based on age or weight?

Viagra is available in three strengths: 25 milligrams (mg), 50 mg, and 100 mg. The information below describes dosages that are commonly used or recommended. But be sure to take the dosage your doctor prescribes for you. They’ll determine the best dosage to fit your needs. In some cases, doctors may adjust your dosage from those shown below. Instead, Viagra’s dosage is based on your age, how well your kidneys and liver are working, and how well the drug works for your erectile dysfunction. Yes, your age is a factor in what dosage of Viagra is right for you. As people get older, their heart, liver, and kidneys don’t work as well as they once did.

This can cause an older adult’s body to break down drugs slower than a younger adult’s body. As a result, drugs stay longer in the body, which can raise the risk of side effects. If you’re 65 years or older, your doctor may start you on a lower dosage of Viagra. The typical starting dosage of Viagra for a 70-year-old would be 25 milligrams (mg). For a 30-year-old who has no other medical conditions, the typical starting dosage would be 50 mg. Regardless of your age, you’ll take your prescribed dose about an hour before sex. If the prescribed dosage of Viagra works well for you and doesn’t cause bothersome side effects, you’ll likely continue taking it. If a dosage works well but causes bothersome side effects, your doctor may suggest a lower dosage. If a dosage doesn’t work to help you get or maintain an erection, your doctor may increase your dosage.
