What is Filitra 20mg Used For?
- Filitra 20mg is the standard-dose Vardenafil tablet by Fortune Healthcare, prescribed for:
- Moderate to Severe Erectile Dysfunction – The standard maximum recommended dose for vardenafil-based ED therapy.
- Upgrade from Filitra 10mg – For men where the 10mg dose proved insufficient in producing consistent erections.
- Diabetic and Post-Prostatectomy ED – Vardenafil 20mg demonstrates strong efficacy in these traditionally difficult-to-treat populations.
How Does Filitra 20mg Work?
- Filitra 20mg provides a full dose of Vardenafil that:
- Delivers maximum recommended PDE-5 inhibition in penile tissue, sustaining peak cGMP concentrations during arousal.
- Achieves robust corpus cavernosum blood filling and venous trapping for firm, sustained erections.
- Works only with sexual stimulation — arousal is essential for erectile response.
How to Use Filitra 20mg
Dosage: One 20mg tablet taken 25–60 minutes before sexual activity.
Timing: Onset 25–60 minutes; duration 4–5 hours.
Precaution: Maximum one dose per 24 hours. Strictly contraindicated with nitrates and QT-prolonging agents. Avoid grapefruit. Disclose all cardiac medications to physician.

Frequently Asked Questions
Q1: What is Filitra 20mg used for?
Filitra 20mg contains Vardenafil 20mg, the standard maximum clinical dose for erectile dysfunction. It is prescribed for men with moderate to severe ED who require full PDE-5 inhibition, or where 10mg proved insufficient.
Q2: What is vardenafil's advantage over sildenafil at the same strength?
Vardenafil demonstrates greater PDE-5 selectivity and tends to work faster than sildenafil. It is particularly effective in men with diabetes-related ED and shows fewer PDE-6 interactions, potentially causing less visual colour disturbance.
Q3: How long does Filitra 20mg take to work?
Filitra 20mg typically starts working in 25 to 60 minutes. Onset can be slightly faster than sildenafil due to vardenafil's pharmacokinetic properties. A light meal is preferred for consistent absorption.
Q4: How long do the effects of Filitra 20mg last?
Effects last approximately 4 to 5 hours, slightly shorter than tadalafil but comparable to sildenafil. Most men find this window more than adequate for sexual activity.
Q5: Is Filitra 20mg the highest recommended vardenafil dose?
Yes. 20mg is the standard maximum recommended daily dose for vardenafil. Above this dose, risks increase substantially without proportional benefit for most men.
Q6: Does Filitra 20mg cause the same visual side effects as sildenafil?
Visual disturbances are less common with vardenafil than sildenafil because vardenafil is more selective for PDE-5 over PDE-6 (which affects retinal function). Colour tinting effects are less frequently reported.
Q7: Can Filitra 20mg be taken by men with diabetes?
Yes. Vardenafil 20mg has particularly strong evidence of efficacy in men with type 1 and type 2 diabetes-related ED. Consult your physician to confirm it is safe given your cardiovascular profile.
Q8: What medications interact with Filitra 20mg?
Significant interactions include nitrates (contraindicated), antiarrhythmics (contraindicated due to QT effects), alpha-blockers, HIV protease inhibitors, CYP3A4 inhibitors (ketoconazole, clarithromycin), and erythromycin. Full medication review is essential.
Q9: Can Filitra 20mg be taken after prostate surgery?
Yes. Vardenafil 20mg has demonstrated efficacy in men with post-prostatectomy ED, particularly nerve-sparing procedures. Recovery of erectile function may require months of treatment alongside physical rehabilitation.
Q10: Can Filitra 20mg cause arrhythmia?
Vardenafil prolongs the QT interval to a small but clinically relevant degree at 20mg. Men with pre-existing QT prolongation, taking antiarrhythmic drugs, or with other cardiac conditions should not take vardenafil without specialist cardiac clearance.
Q11: Can I take Filitra 20mg and alcohol together?
Moderate alcohol is generally tolerated, but heavy drinking should be avoided with Filitra 20mg. Combined blood pressure lowering from alcohol and vardenafil increases the risk of hypotension, dizziness, and falls.
Q12: Do I need a prescription for Filitra 20mg?
Yes. Vardenafil is a prescription-only medicine. A physician assessment, particularly regarding cardiac rhythm and QT interval, is essential before starting treatment.
