Missed Dose

This article describes the dosage of Viagra, as well as its strengths and how to take it. To learn more about Viagra, see this detailed overview of Viagra. This section covers common questions about the dosage of Viagra. You may have heard Viagra described as the “little blue pill.” Viagra comes as a tablet that you swallow. It’s a blue tablet that has a rounded diamond shape. 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. No, the dosage of Viagra isn’t based on a person’s weight. 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.

How should this medicine be used?

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.

In case of emergency/overdose

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.

Less common

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. 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 doesn’t work to help you get or maintain an erection, your doctor may increase your dosage. You should not take more Viagra than your doctor prescribes.

Before taking this medicine

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.

Follow safe, recommended doses

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.

2.2 Use with Food

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.

What should I tell my healthcare provider before taking sildenafil?

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. In this case, Viagra could take up to an hour longer to start working.
