Why is this medication prescribed?
My belief is that clinical experience will show them to be similar. Data from Six Degrees Survey, October 2001. men who require fast onset or better absorption should avoid fatty meals or take these pills on an empty stomach; start foreplay later in older patients (who may need up to 2 hours to absorb the medicicne); do not give up before making at least 3 attempts at intercourse having at the maximum dose: Viagra 100 mg, Levitra 20mg. Viagra and vardenafil must be taken 60 minutes before sex and allow for sexual stimulation to work. Vardenafil is now available only as a generic drug, while Viagra is available in both brand and generic versions.

Levitra and Viagra are both effective treatments for erectile dysfunction (ED), but subtle differences in availability and dosing may influence your choice. Understanding these differences can help you and your healthcare provider decide which medication is best for you. Vardenafil, the active ingredient in Levitra, is now only available as a generic drug in the U.S. While healthcare providers might still call it Levitra, pharmacies dispense it as vardenafil. Below is a chart detailing key similarities and differences between these two FDA-approved prescription medications. Generally, Viagra and vardenafil have similar recommendations for how to take them, which are: Both should be taken about 60 minutes before sex for optimal response.
- Pregnant or breastfeeding women should avoid Vardenafil.
- Consult a healthcare provider about safe options.
- Use only as directed by your physician.
However, Viagra can be taken anywhere between 30 minutes and up to four hours before sexual activity. Sexual stimulation is required for the medication to take effect. Do not take more than one tablet (regardless of dosage) in a 24-hour period.
- The typical Vardenafil dose ranges from 5 to 20 mg.
- Take Vardenafil at least 25-60 minutes before activity.
- Do not exceed one dose within 24 hours.

Before Using
Experts also recommend lifestyle changes and mental health referrals in ED treatment. Adjusting diet and increasing exercise may help. Numbness, burning, or tingling in the hands, arms, feet, or legs Pain in the muscles, back, arms, or legs A serious eye condition known as nonarteritic anterior ischemic optic neuropathy (NAION) can occur with vardenafil or Viagra. If you notice vision changes or loss, stop taking these medications and seek medical help immediately. Individuals with a history of NAION or a "crowded" optic disc are at greater risk.

Some may also experience color vision changes, such as seeing blue tinges or difficulty telling blue and green apart. Inform your healthcare provider about any heart problems, as there are heart-related risks with sexual activity. You have an erection lasting more than four hours. You have symptoms of an allergic reaction, such as hives, difficulty breathing, or swelling of the face, lips, tongue, or throat. You have vision changes or vision loss in one or both eyes. Like vardenafil and Viagra, Cialis takes about 60 minutes to work and must be used in combination with sexual stimulation.
Usual Geriatric Dose for Erectile Dysfunction
PDE5 inhibitors, including vardenafil and Viagra, work in the same way. When used with sexual stimulation, they increase blood flow to the penis, which can lead to an erection. These medications do not cure ED, or prevent pregnancy or sexually transmitted infections (STIs). Both medications reach maximum effect between 30 minutes to two hours, typically around 60 minutes. Their effects can last up to four hours.

Both medications can last up to about four hours after taking them. Some research shows that a high-fat meal might affect vardenafil. However, clinical studies indicate no need to alter dosage or food intake. The prescribing information states that vardenafil can be taken with or without food. Like vardenafil, Viagra can also be taken with or without food. There are two ways to take Cialis. The first way is similar to vardenafil or Viagra, which is to take it about an hour before sexual activity. Cialis can also be taken at a low dose once a day regularly, without regard to sexual activity.

Tips for Taking Vardenafil and Viagra Effectively
Although Viagra, Levitra and Cialis are safe and effective they do, like all medications, have disadvantages. They essentially enhance partial (sexual) erections, rather than initiating them. At best, the response rate among men with advanced ED (for example following radical prostatectomy) is 30%. Fewer than 505 of men with Diabetes will respond. Correct administration of Viagra and Levitra is critical, and if one does not work when taken correctly, no other oral “Viagra like drug” (PDE5 inhibitor like Levitra or Cialis) will either.
Where can I buy Levitra safely?
In conclusion, the potencies of Viagra, Levitra and Cialis are broadly similar, but each has unique pharmacological properties related to its molecular structure. Viagra is an exemplary PDE-5 inhibitor that, after 10 years of widespread clinical use, is acknowledged to be effective and particularly well tolerated. Cialis and Levitra are the newer medications and are similar to Viagra in their efficacy and contraindications. The only new attributes of clinical significance are the lack of food interaction and the long duration of action of Cialis. This may translate into greater efficacy of the first dose as well as a return to more spontaneous (normal) initiation of sexual activity (broader window of opportunity). When facing erectile dysfunction, most men find themselves choosing between tadalafil (Cialis) and vardenafil (Levitra). Both are proven PDE5 inhibitors with excellent safety profiles, but here's what most comparison guides won't tell you: the choice isn't always either-or. Tadalafil offers a 36-hour effectiveness window, while vardenafil works faster and may be more effective for non-responders.
In case of emergency/overdose
However, taking Viagra with a high-fat meal can make the medication take about an hour longer to work. In addition to vardenafil and Viagra, other PDE5 inhibitors include Stendra (avanafil) and Cialis (tadalafil). Some PDE5 inhibitors also treat different conditions. For example, Revatio contains sildenafil, like Viagra, but is used for pulmonary fildena tablet arterial hypertension (high blood pressure in the lungs). Healthcare providers may also prescribe Cialis in lower doses for benign prostatic hyperplasia (BPH).
Mol Pharmacol
Few studies directly compare vardenafil and sildenafil. An older study of these drugs, plus tadalafil, found vardenafil to be more potent than sildenafil, though both effectively treated ED. Tadalafil (Cialis) was preferred for its longer-lasting effects but was similarly effective. Another study found vardenafil to be better tolerated than sildenafil. The American Urological Association does not favor one over the other, focusing on individual suitability. However, ED involves both physical and psychological factors that a single medication may not fully address—which is why leading-edge treatments now combine multiple approaches. This guide covers everything about tadalafil vs vardenafil: effectiveness, side effects, and which suits your situation. More importantly, we'll explore why some men find better results with comprehensive solutions that harness both medications' strengths.
Vardenafil Alternatives
Question: Is it possible to identify potential non-responders to oral therapy? Answer: No, it is not possible to identify potential non-responders to a PDE 5 inhibitor such as Cialis, Levitra or Viagra, other than by a trial of these medications in the setting of sexual activity. Patients, who appear to be non-responders to Viagra or Levitra, need to repeat a trial on an empty stomach a few different times before giving up. Cialis absorption and onset of action is not affected by food. The 20-30% who still do not respond generally have ED related to an irreversible physical abnormality due to chronic poor blood flow (often smoking-related) or damaged penile tissue (often diabetes, high cholesterol and after prostate cancer surgery).
More common
The best option for these patients remains an inflatable penile prosthesis. Question: You said that the PDE5 inhibitors were comparable in efficacy. What about reports that Levitra is more effective than Viagra in treating ED among men with diabetes? Answer: Clinical trial reveals that all three medications have the same success regardless of patient age, underlying medical condition or severity of erectile dysfunction. There is no head-to-head evidence of that, and what literature there is may be misleading. Both tadalafil and vardenafil belong to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. They work by blocking the PDE5 enzyme, which allows blood vessels in the penis to relax and fill with blood during sexual arousal. Tadalafil (brand name Cialis) was FDA-approved in 2003 and is known for its long duration of action. It's the active ingredient in both daily and as-needed ED treatments.
- Vardenafil may cause a fainting sensation in some users.
- Stay seated or lying down if dizziness occurs.
- Rise slowly from sitting or lying positions.
Vardenafil (brand name Levitra) received FDA approval in 2003 as well and is recognized for its fast onset and high effectiveness rates, particularly in men who haven't responded well to other PDE5 inhibitors.
