Who Makes Levitra?



The medication is manufactured by Bayer Pharmaceuticals. It is marketed by GlaxoSmithKline and Schering-Plough.

What Is It Used For?

Levitra has been licensed to treat erectile dysfunction. Erectile dysfunction (ED), also known as impotence, can be a total inability to achieve erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Essentially, erectile dysfunction is the repeated inability to get or keep an erection firm enough for sexual intercourse.

How Does It Work?

Levitra works by blocking a chemical that reverses an erection by causing blood to flow out of the penis. More blood in the penis means an improved erection.

Effects of Levitra

The effects of this medication can include:

Achieving and maintaining an erection during sexual activity

Having a harder erection during sexual activity

Experiencing greater frequency of orgasms

Having increased satisfaction with, and enjoyment of, intercourse.

In previous clinical studies, up to 80 percent of men reported that Levitra improved their erections. The drug was also shown to be effective in men with various health problems and medical conditions.

When Does It Start Working and How Long Does It Last?

Many men wonder, "How long do I have to wait for Levitra to work?" The time it takes for it to start working will vary depending on the individual. In clinical studies, it began to work in about one hour. How long Levitra continues to work will also depend on the individual. In most cases, it can work for up to four hours.

When and How Do I Take It?

Here are some general considerations for when and how to take Levitra:

The medication comes in tablet form. It is taken as needed, usually one hour before sexual activity. However, it is not recommended that you take Levitra more than once in a day.

While it is recommended that you take your dose with a glass of water, you may take it with or without food. Taking it with a high-fat meal may decrease the amount of Levitra in the blood.

Do not break, chew, or crush the tablets.

For the medication to work properly, you have to take it as prescribed. Levitra will not work if you stop taking it.

Dosing Information for Levitra

The dosage your healthcare provider recommends will vary depending on a number of factors, including:

Your age

Other medical conditions you may have

Other medications you may be currently taking.

As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Side Effects

(The side effects listed below are NOT a complete list of possible side effects you may experience with Levitra. Your doctor can provide you with a comprehensive list of these side effects.)

As with any medicine, there are possible side effects with Levitra. However, not everyone who takes it will experience side effects. In fact, most people tolerate it well. When side effects do occur, they are usually minor, meaning they require no treatment or are easily treated by you or your healthcare provider.

The most common side effects of Levitra include:

Headache -- 15 percent of people

Facial flushing -- 11 percent of people

Indigestion or an upset stomach (known as dyspepsia) -- 4 percent of people

Stuffy or runny nose (rhinitis) -- 9 percent of people

Flu-like symptoms -- 3 percent of people

Nausea -- 2 percent of people

Dizziness -- 2 percent of people

Back pain -- 2 percent of people.

If you have cardiovascular disease or significant heart disease risk factors, you have an increased risk of serious problems with the heart, brain, and blood vessels during treatment with Levitra. This can lead to dangerous side effects such as heart attack, stroke, or sudden death.

Also, Levitra has been linked to rare cases of a condition called non-arteritic anterior ischemic optic neuropathy (NAION). This condition can lead to sudden loss of vision in one or both eyes. If you experience any loss of vision, contact your healthcare provider immediately.
