Guidelines for Taking Vardenafil with or without Food
The American Urological Association does not favor one over the other, focusing on individual suitability. 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.
Cialis (Tadalafil)
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.
Who should not take Cialis:
Below is a chart detailing key similarities and differences between these two FDA-approved prescription medications. PDE5 inhibitors, including vardenafil and Viagra, work super p force 200mg 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. 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.

What special precautions should I follow?
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.
Professional resources
Like vardenafil, Viagra can also be taken with or without food. 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 arterial hypertension (high blood pressure in the lungs). Vardenafil or Viagra interact with various drugs, so be sure to tell your healthcare provider about all of the medications you take, including prescription and over-the-counter (OTC) drugs, vitamins, and supplements.
- 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 or Viagra should never be taken with nitrate drugs such as isosorbide mononitrate or nitroglycerin.
Brand names
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. 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.
How Long Does Vardenafil Take to Work?
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). 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. Vardenafil or Viagra can also interact with other medications, such as: Alpha blockers, which are used to treat BPH and high blood pressure: Examples include Flomax (tamsulosin) and Uroxatral (alfuzosin) Other blood pressure medications, such as Norvasc (amlodipine) Certain antifungals, such as ketoconazole and itraconazole To get the best results, follow the instructions on your medication's label for taking it.
| Interaction Partner | Effect on Vardenafil | Notes |
|---|---|---|
| CYP3A4 Inhibitors | Increased Vardenafil plasma levels | Use with caution, dose adjustment needed |
| Alpha-blockers | Risk of hypotension | Start with low doses, monitor closely |
| Grapefruit Juice | Increases drug levels | Avoid or limit consumption |
| Other PDE5 inhibitors | Additive effects, risk of adverse events | Generally not recommended to combine |
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.
How should this medicine be used?
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). 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.
A Randomised, Placebo-Controlled Study to Assess the Efficacy of Twice-Daily Vardenafil in the Treatment of Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia
There is no head-to-head evidence of that, and what literature there is may be misleading. 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. However, Viagra can be taken anywhere between 30 minutes and up to four hours before sexual activity.
Vardenafil Dosages for Treating Erectile Dysfunction
Duration was important only in terms of lasting long enough to complete intercourse. Few men (or their partners) felt that multiple erections, or the ability to achieve them over time, were critical as long as one dose was enough for a successful encounter. Most complaints were about high cost or lack of insurance coverage. An underlying desire was reported by most couples for initiation of sex to be normal (spontaneous and natural). Few patients fully understood the duration of activity that Viagra can provide, and its advantages.
Mol Pharmacol
Cialis may indeed fulfill the desire that couples and patients with ED have for the initiation of sex to be normal (spontaneous and natural). 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. Sexual stimulation is required for the medication to take effect.
How Effective is Vardenafil?
Alternative oral therapies for Erectile Dysfunction (availability may vary geographically) are Uprima (apomorphine), and phentolamine. Both Uprima and phentolamine have very low or no efficacies and therefore for present purposes will not be addressed. Uprima is approved for the treatment of Erectile Dysfunction in Europe and initial sales have not been very impressive (less than 20% of ED market). Refill rates are dismal supporting lack of efficacy. Phentolamine’s application to the FDA was withdrawn and the drug is not available.
Binding of tritiated sildenafil, tadalafil, or vardenafil to the phosphodiesterase-5 catalytic site displays potency, specificity, heterogeneity, and cGMP stimulation
Although Viagra, Levitra and Cialis differ in their biochemical potency and selectivity, and in onset and duration of action, it is important not to extrapolate those findings inappropriately to the clinical setting. For example, greater biochemical potency does not necessarily translate into enhanced clinical efficacy. In short, there appears to be little biochemical or clinical differences between the three agents except for the lack of food interaction and the duration of activity for Cialis. All three medications are contraindicated in patients who take nitrates. A recent survey looking at what patients with ED really want from their treatment found that efficacy and a favorable side-effect profile were the highest priorities³ Fast onset was desirable, but there were major differences in what was considered fast. Do not take more than one tablet (regardless of dosage) in a 24-hour period.
- Vardenafil can interact with nitrates causing dangerous drops in blood pressure.
- Inform your doctor about all medications before use.
- Avoid alcohol while taking Vardenafil to reduce side effects.
If your results with either medication are not as expected, consult your healthcare provider for professional medical advice.
Overdose/Missed Dose
Healthcare providers may also prescribe Cialis in lower doses for benign prostatic hyperplasia (BPH). 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. You may need a higher or lower dose or a different medication. Cialis is a commonly prescribed medication for ED. Like vardenafil and Viagra, Cialis takes about 60 minutes to work and must be used in combination with sexual stimulation.
- Common side effects include headaches and flushing.
- Serious side effects are rare but may include vision changes.
- Consult a doctor if you experience chest pain.
