Levitra Generic contains vardenafil — the third PDE5 inhibitor approved in Spain, developed by Bayer and available in doses of 5mg, 10mg and 20mg. It shares its mechanism of action with sildenafil (Viagra) and tadalafil (Cialis), but has a differentiated pharmacological profile that makes it the first clinical choice for certain patient profiles — especially men with type 2 diabetes, those who tried Viagra without result, or those who need rapid onset of action. Discreet delivery across Spain in 4–7 days.
Full Comparison: Vardenafil vs Sildenafil vs Tadalafil
| Parameter | Vardenafil Levitra Generic |
Sildenafil Viagra Generic |
Tadalafil Cialis Generic |
|---|---|---|---|
| Onset of action | 10–25 min (can be the fastest) | 30–60 min | 30–60 min |
| Duration of effect | 4–6 hours | 4–6 hours | Up to 36 hours |
| Influence of food | Mild — avoid very fatty meals | Moderate — better on empty stomach | None |
| Efficacy in diabetics | 72% successful intercourse | 63% | ~65% |
| Overall efficacy (20mg) | 80% | 84% | ~81% |
| Orodispersible form | Yes — absorption independent of food | No | No |
| Blue vision effect | Very uncommon | Common (1–10%) | Very uncommon |
| Daily therapy | Yes — 5mg/day | Not approved | Yes — 2.5mg or 5mg/day |
Urologist's conclusion: Vardenafil is not absolutely better or worse than sildenafil. It is the PDE5 inhibitor with the highest demonstrated efficacy in diabetic patients (72%) and the one that can act fastest (from 10 minutes). For men with no response to Viagra or with type 2 diabetes — Levitra is frequently the second option that delivers results.
Who Levitra Is the First Choice for — and Who It Is Not
The Diabetic Advantage — Why the Data Matters
Orodispersible Form — The Format That Changes the Equation
Standard film-coated tablet
- Swallowed with water
- Onset: 25–60 minutes
- Fatty meals slightly reduce absorption
- Doses: 5, 10, 20mg
Orodispersible (ODT) — key advantages
- Dissolves under the tongue
- Onset: potentially 10–15 minutes
- Absorption NOT affected by fatty meals
- No water required — total discretion
- Slightly higher bioavailability
Why Vardenafil Causes Less Visual Disturbance Than Sildenafil
Blue-tinted vision (cyanopsia) associated with sildenafil occurs because it also inhibits PDE6 — present in the retina. Vardenafil has greater selectivity for PDE5 over PDE6, significantly reducing this side effect. For men who have experienced visual disturbance with sildenafil, switching to vardenafil often eliminates this problem while maintaining erectile efficacy.
Dosage and How to Take
- Recommended starting dose: 10mg, 25–60 minutes before sexual activity
- Adjustment: If 10mg is insufficient → 20mg. If bothersome side effects → 5mg
- Maximum dose: 20mg per use, once in 24 hours
- With meals: Can be taken with or without a light meal. Avoid very fatty meals which delay absorption
- Alcohol: Maximum 1–2 drinks — both are vasodilators
- Over 65 years: Recommended starting dose 5mg — greater sensitivity
- Daily therapy: 5mg once daily
Side Effects
Common (1–10%)
- Headache
- Facial flushing
- Nasal congestion
- Dyspepsia
- Mild dizziness
Uncommon — contact doctor
- Hypotension
- Blurred vision
- Tachycardia
- Muscle or back pain
Rare — A&E immediately
- Priapism (>4 hours)
- Sudden vision loss
- Sudden hearing loss
Contraindications — Key Warnings Specific to Vardenafil
- Nitrates (nitroglycerin, isosorbide dinitrate/mononitrate) — absolute contraindication, severe hypotension
- Poppers (amyl or butyl nitrite)
- Riociguat (Adempas)
- Class IA and III antiarrhythmics (quinidine, procainamide, amiodarone, sotalol) — risk of QT interval prolongation. This is vardenafil's most important specific contraindication — not equally shared by sildenafil or tadalafil
- Moderate-severe hepatic impairment — adjust dose or avoid
- Under 18 years of age | Women
- Heart attack or stroke in the last 6 months
QT interval note: Vardenafil causes mild QT interval prolongation. In healthy people this has no clinical relevance, but in those taking class IA antiarrhythmics (quinidine, procainamide) or class III (amiodarone, sotalol) it can cause serious arrhythmias. If you take any heart medication, consult your doctor before taking vardenafil.
Frequently Asked Questions
If Viagra has not worked for me, will Levitra work? It is possible. Approximately 30–50% of patients who do not respond to sildenafil do respond to vardenafil or tadalafil. Although all are PDE5 inhibitors, their molecules are slightly different and individual response varies. It is worth trying another inhibitor before considering more invasive options.
Is Levitra Generic as effective as original Levitra by Bayer? Yes — same molecule (vardenafil), same dose, same bioavailability. The generic can be up to 80% cheaper without the patent and marketing costs of Bayer.
Can I take Levitra if I have high blood pressure controlled with medication? It depends on which medication. If you take alpha-blockers (tamsulosin, doxazosin), there is a risk of additive hypotension — separate by at least 6 hours or use a lower dose (5mg). For other antihypertensives the risk is lower but consult your doctor. Never combine with nitrates.
What is the difference between Levitra 10mg and 20mg? The recommended starting dose is 10mg. On-demand use up to 20mg if the response is insufficient. Efficacy rises from 76% (10mg) to 80% (20mg) in clinical studies. If 10mg works well, there is no reason to use 20mg.
