Vardenafil is a medicine used to treat male sexual function problems such as erectile dysfunction (ED). The most popular Vardenafil brand name is Levitra, and it is taken by mouth. ED is when a man cannot get or keep an erection firm enough for sexual activity. Vardenafil works on the penis, allowing it to become hard. It does not change how the brain thinks about sex.

Vardenafil (Levitra, Staxyn) belongs to a class of medications called PDE5 inhibitors. PDE5s work by increasing blood flow to the penis when sexual stimulation occurs.

How Is Vardenafil Used?

Vardenafil comes in two forms; one is a fast-disintegrating tablet that dissolves in the mouth and is swallowed without water, another is a tablet that is usually taken 60 minutes before sexual activity. This medication is most effective when taken as needed. Vardenafil works by relaxing blood vessels and increasing blood flow to particular parts of the body.

For people who have certain health problems or are taking certain medicines, your doctor may tell you to take vardenafil less often, or not at all.  Do not take more than your doctor tells you to. Keep the blister pack together and make sure that none of the blisters are torn or broken. If they are, they could be contaminated.

It’s important to read the instructions that come with your package, then take the tablet out of the package. Tablets should not be shoved into foil. Place the tablet on your tongue and close your mouth right away.

The tablet will quickly break down. Do not mix the rapidly dissolving tablet with water or any other liquids, because it will break down too quickly. Your doctor will probably start you off with an average dose of vardenafil tablets, and he or she will increase or decrease your dose based on how well you take the medicine.

Vardenafil Side Effects

Vardenafil side effects

It is believed that Vardenafil and other PDE5 inhibitors aid in the achievement of an erection by inhibiting the action of the enzyme PDE5. This enzyme can be found in high concentration in your penis, but it can also be found in blood vessels throughout your body, including your brain. 

Because of this, PDE5 inhibitors can cause a wide range of side effects. 

The following are the most frequently reported short-term side effects of vardenafil in clinical trials: 

  • Headache
  • Indigestion
  • Flushing
  • Congestion
  • Nausea

Some patients experienced a sudden loss of some or all of their vision after they took vardenafil or other medications that are similar to vardenafil. The vision loss was permanent in some cases. It is not known if the vision loss was caused by the medication. If you experience a sudden loss of vision while you are taking vardenafil, call your doctor immediately. Do not take any more doses of vardenafil or similar medications such as sildenafil (Viagra) or tadalafil (Cialis) until you talk to your doctor.

Some patients experienced a sudden decrease or loss of hearing after they took vardenafil or other medications that are similar to vardenafil. The hearing loss usually involved only one ear and may not get better. It is not known if the hearing loss was caused by the medication. If you experience a sudden loss of hearing, sometimes with ringing in the ears or dizziness, while you are taking vardenafil, call your doctor immediately. Do not take any more doses of vardenafil or similar medications such as sildenafil (Viagra) or tadalafil (Cialis) until you talk to your doctor.

Priapism, which occurs when an erection lasts longer than 4 hours, is a very rare side effect that may occur. This has the potential to harm the penis. When an erection lasts for an excessive amount of time, the individual should seek medical attention.

Vardenafil Dosage

Vardenafil Dosage

Taking more vardenafil than the recommended dosage can increase your risk of mild to serious side effects. 

In healthy male individuals, the maximum dose that researchers have evaluated in humans is 120 milligrams at one time. The majority of study participants experienced back pain, muscle pain, or blurry vision at this daily dose. Daily doses of up to 40 milligrams were tolerated for four weeks with no serious side effects. 

Vardenafil has a recommended starting dose of 10 milligrams. 

It is recommended that you take Vardenafil 1 hour before sexual activity. The amount that is best for you, however, can be higher or lower. A doctor can advise you on how much to take on a daily basis.

Vardenafil drug interactions

Vardenafil and other PDE5 inhibitors may interact with other medications you’re currently taking. It’s crucial to talk to your doctor before starting to take vardenafil.

Medications known to interact with vardenafil include drugs with nitrates, alpha blockers, or drugs that are used to regulate blood pressure. These drugs can, at worst, interact with vardenafil in a dangerous way, or at a minimum, decrease the effectiveness of the drug. 

Precautions Before Using Vardenafil

Although Levitra and other forms of vardenafil have the potential to be effective treatments for erectile dysfunction (ED), it’s important to discuss your medical history with a doctor before taking it.

Vardenafil (used for erectile dysfunction) isn’t suitable for everyone. People with certain conditions, like heart disease, shouldn’t take it.

If you have conditions such as low blood pressure or unstable angina — or if you recently had a stroke — you should not take Vardenafil.

Although vardenafil is generally considered to be safe and effective, it also entails some important restrictions and warnings for people with kidney problems, liver problems, hereditary retinal disorders, and severe heart conditions. Patients with these medical conditions should discuss the benefits and risks of using vardenafil with their health care providers.

Vardenafil is the brand name for Levitra, a drug that helps men to get and keep an erection. While it may be approved in some countries, the U.S. Food & Drug Administration (FDA) has not approved it to treat any specific condition in women.

Vardenafil Vs Viagra

Vardenafil vs Viagra

The PDE-5 inhibitor Levitra (vardenafil), also known by its generic name vardenafil, and the sildenafil-containing drug Viagra, also known by its generic name sildenafil, are both available on the market. Both medications are available in tablet form as both a brand name and a generic version. 

In the treatment of erectile dysfunction, these medications should not be taken more than once a day, regardless of the dose. For Levitra or Viagra to be effective, it must be taken in conjunction with sexual stimulation.

Erectile dysfunction is a condition that can be treated with the help of Levitra and Viagra. Both medications have been used off-label for conditions such as Raynaud’s phenomenon and female sexual arousal disorder, among other things. It is only at a dose of 20 mg three times daily that the sildenafil formulation known as Revatio (NOT Viagra) is indicated for the treatment of pulmonary arterial hypertension, and not at the higher doses available in the Viagra formulation (25 mg, 50 mg, or 100 mg).

We know from clinical studies that both Levitra and Viagra have been shown to be effective, but which is the superior product? While Levitra was found to be more potent than Viagra in a study comparing drugs for erectile dysfunction, both drugs were found to be equally effective in the treatment of erectile dysfunction. The only advantage Levitra had over Viagra was that it did not interfere with color perception, which is something that can happen with Viagra on occasion. Another study discovered that both medications were well-tolerated, with Levitra being marginally better tolerated than Viagra. 

If you want to take Levitra or Viagra, the only person who can determine which medication is the most effective for you is your healthcare provider, who will consider your medical history and condition(s), as well as any other medications you are taking that could interact with Levitra or Viagra.


Erectile dysfunction is a condition that affects more than 20 million men in the United States. It is the inability to get or keep an erection that can be the result of psychological or physical factors.

Treatments for erectile dysfunction include medications, which are used to treat a variety of conditions. The most common of these are Viagra, Levitra, and Cialis. These medications can be taken orally, or they can be injected directly into the penis.

We’ve discussed the benefits of Vardenafil, the generic form of Levitra, in this article, but it’s also worth stressing that these benefits carry risks of side effects. It’s best to talk to your doctor before taking Vardenafil, especially if you have a medical condtion or are taking other medication.
