Levitra vs Viagra: Which Vardenafil Treatment May Suit You Better?

Written by Pete Lumle  |  Medically Reviewed by Cornelius Brooks, MD

Levitra and Viagra are two of the most popular medicines for the treatment of erectile dysfunction (ED) on the market. Both drugs are designed to improve blood flow to the erectile tissue of the penis. These medications work similarly but differ significantly in their duration and timing of effectiveness. Levitra Generic contains vardenafil as its main ingredient, tends to be less affected by food or alcohol, and therefore offers more flexibility with meal choices beforehand.

Viagra, on the other hand, is generally recommended to be taken on an empty stomach for suitable absorption into the bloodstream. Both these drugs require sexual stimulation to activate their function effectively. Below, we’ve discussed the differences between Levitra and Viagra, their effectiveness, their speed of working, how long they last, their side effects, safety, and lastly, their interactions. Knowing these key differences will help maximize the effectiveness of the medication and minimize any potential risk associated with the drug.

 

Levitra vs Viagra: Which Vardenafil Treatment May Suit You Better?


Dosage and forms of Vardenafil

Vardenafil Tablets are available in various doses. A typical Levitra dose starts at 10 mg daily, but it also comes in 5 mg and 20 mg dosages. Your best dosage will depend on certain health factors. This includes blood pressure, risk of heart attack, liver problems, and use of other medications, which can increase the risk of side effects. As with many other types of medication, Levitra does not work equally well for everyone. Some men may find 10 mg highly effective, while others need to take the 20 mg dose to get an erection hard enough for sex.

It is best to start with the lowest dose (i.e., 10 mg), and your doctor may later increase or decrease it based on your health status. This way, you can buy Generic Levitra online in lower and higher doses based on your doctor’s suggestion.

Levitra Vs Viagra: Understanding the Differences

Both Levitra and Viagra are effective at treating ED. However, a few differences matter when choosing between them.

  • Both Levitra and Viagra are meant to be taken on an as-needed basis for short-term treatment of ED.  However, Levitra may last slightly longer than Viagra. Research suggests Levitra may work for up to 8 hours after you take it. Viagra’s effects mainly last at least 4 hours after taking it.
  • Food does not significantly affect Levitra. This means Levitra can be taken with a high-fat meal, which has less impact on onset than Viagra. On the other hand, if Viagra is consumed with a high-fat meal, it will take longer time to feel its effects.

Levitra (also known as vardenafil) is available as oral tablets in different strengths, such as 2.5 mg, 5 mg, 10 mg, and 20 mg. On the other hand, Viagra (also known as sildenafil) is available in different strengths such as 25 mg, 50 mg, or 100 mg oral tablets. Besides the oral tablets, both of these medications are available as jellies too.

Levitra or Viagra: Understanding the effectiveness

Levitra and Viagra are similarly effective medications for treating ED. When taken as prescribed, both medicines may improve the strength and duration of erections.

In a clinical study, 84% of participants using Levitra reported improved erections by the 12th week. This medicine has shown good first-dose success when prescribed at 20 mg. On the other hand, in a clinical study, 92% of participants who took Viagra for ED reported that Viagra improved the strength, duration, and frequency of erections and observed overall satisfaction with their sex lives at the 36th week. A healthcare provider can decide which medication is the best fit.

Levitra Vs Viagra: Understanding the Speed of Working

Levitra and Viagra take approximately the same duration to work.

Levitra

For most people, Levitra begins to work in about one hour, although it may begin working in as little as 30 minutes. Similar to Viagra, it can be consumed with or without food, but a high-fat meal may cause the medicine to take longer to work.

Viagra

Viagra may be effective within 30 minutes or less, but can take up to 2 hours. Most people find that it starts working around 60 minutes after taking it. For this reason, it is mainly taken about 60 minutes before performing any sexual activity, although it can be consumed anywhere from 30 minutes to 4 hours beforehand.

Viagra on an empty stomach works the fastest; consuming it with food (avoid heavy or fatty meals) is safe, but may delay the onset of the medication.

Levitra Vs Viagra: Understanding the Duration They Last

Levitra lasts longer than Viagra, with effects extending up to 8 hours as compared with Viagra’s typical duration of around 4 hours.

Levitra

Levitra has a half-life of 4 to 5 hours, indicating it takes about 4 to 5 hours for half of the concentration to leave the body. A study indicated that participants with erectile dysfunction who consumed Levitra 8 hours before sexual activity maintained improvements in erectile function.

This demonstrates that Levitra may have a longer duration of action compared to Viagra. Duration is also affected by additional factors such as lifestyle, medical history, habits, diet, age, and other considerations.

Viagra

Viagra has a half-life of 4 hours. It means it takes around 4 hours for half of the Viagra concentration to leave the body. Research indicates the effects of Viagra mainly last for at least 4 hours.

Side effects of Levitra and Viagra

The side effects of both drugs are very similar and may be based on medical history, dosage, and other parameters. Priapism(an erection with pain that lasts more than 4 hours) is one of the serious side effects, along with low blood pressure.

The common side effects of Levitra and Viagra are:

  • Facial flushing

  • Backpain

  • Heartburn/Indigestion

  • Headaches

  • Nausea

  • Stuffy nose

Is Levitra or Viagra safer?

Levitra and Viagra are both meant to be safe and effective alternatives for treating ED. However, specific situations such as heart conditions or taking interacting drugs may make either medicine inappropriate for some people.

Consulting a healthcare provider before starting Levitra or Viagra, is essential. Discussing medical history and over-the-counter supplements or prescription medicines being taken can help prevent drug interactions.

Levitra vs Viagra Interactions

Since both Levitra and Viagra are PDE5 inhibitors, they have warnings about potential drug interactions. They can significantly lower blood pressure, which is one of the most potential risks with PDE5 inhibitors. This can happen when Levitra or Viagra is taken with nitrates. Nitrates are usually used to treat chest pain or other heart conditions. Amyl nitrites, also known as poppers, are a type of nitrate. Used in combination with PDE5 inhibitors, they can cause blood pressure to decline to dangerously low levels, with potentially fatal results.

People consuming alpha-blockers to reduce blood pressure or treat benign prostatic hyperplasia(BPH) should exercise caution while consuming Levitra or Viagra. Alpha-blockers reduce blood pressure, as do PDE5 inhibitors, so combining the two medicine classes can lead to dangerously low blood pressure.

Consuming Levitra or Viagra with riociguat for pulmonary hypertension can also lead to a drop in blood pressure. Specific medications may disrupt how the liver processes other medications by affecting the CYP34A4 enzyme system. Medicines that inhibit the CYP3A4 enzyme may change the strength of Levitra or Viagra in the body, elevating the risk of side effects; examples include ritonavir, ketoconazole, erythromycin, and indinavir. Grapefruit juice may also inhibit this enzyme and affect how vardenafil or sildenafil works.

Conclusion

Both Levitra and Viagra have been primarily used in treating erectile dysfunction, with many clinical studies supporting their efficacy over placebo treatments. They are usually known as erectile dysfunction medications. Either of the drugs should be taken carefully and strictly under a doctor’s supervision. Both work by enhancing the effect of nitric oxide in relaxing muscles around blood vessels in the penis, enhancing increased blood flow during sexual stimulation.

Both medicines are now available in generic forms, which will help you save on costs. It’s important to note that neither drug will produce an erection immediately after taking such medicines; both require sexual stimulation to work.

 

Frequently Asked Questions

  • How does Levitra work for erectile dysfunction?

    Levitra treats erectile dysfunction by blocking the PDE5 enzyme to increase blood flow to the penis during sexual arousal. Blood can then flow more easily into the penis tissues, giving you an erection.

  • What is the difference between Levitra and Viagra?

    Levitra and Viagra are prescription medications for erectile dysfunction. Levitra contains vardenafil and is available only in generic form. Viagra contains sildenafil and is offered as both a brand and generic product. Typical doses for Levitra are 5 mg, 10 mg, or 20 mg once daily, while Viagra is usually prescribed at 25 mg, 50 mg, or 100 mg once daily.

  • How long does vardenafil last?

    Vardenafil mainly lasts between 5 to 7 hours. However, everyone's experience is different. One study suggests vardenafil may work for up to 8 hours for some people. For some, it may last up to 12 hours. But you should only take one dose of vardenafil in 24 hours. Consuming more than prescribed can raise the risk of side effects.

  • When should Levitra be taken?

    You should consume Levitra approximately 25 to 60 minutes before sexual activity, although it may start working in as little as 30 minutes. It can be taken with or without food, but a high-fat meal may cause it to take longer to work.

  • What are the common side effects of vardenafil?

    Common vardenafil side effects include headache, stuffy nose, flushing, stomach upset, sinus infection, dizziness, nausea, or back pain. If, after consuming vardenafil, you experience these side effects, they will fade away as your body processes and clears the medication.
