About the medicine

What it is and how it works

Vardenafil is a PDE5 inhibitor with fast onset and high selectivity. Some people who had side effects with sildenafil tolerate it well. The doctor weighs which PDE5 fits your case best.

It's usually prescribed as 10 mg taken 25 to 60 minutes before sexual activity, with doses adjustable to 5 or 20 mg based on response and tolerance. Light meals don't affect it significantly; very fatty meals can delay onset.

Who it is for

  • Adult men with erectile dysfunction; sexual stimulation is still required
  • One tablet 25 to 60 minutes before sex, at most one dose in 24 hours

Safety summary

Nitrates and poppers are contraindicated: blood pressure can fall dangerously

Vardenafil 5/10/20mg16 questions
Why choose vardenafil among PDE5s?
It has fast onset and high selectivity. Some people who had side effects with sildenafil tolerate it well. The doctor weighs which PDE5 fits your case best.
Usually 10 mg taken 25 to 60 minutes before sexual activity, with doses that can be adjusted to 5 or 20 mg based on response and tolerance.
More questions
It must not be combined with nitrates and requires caution in arrhythmias or long QT. The doctor reviews your cardiovascular history and medication with you before prescribing.
Light meals do not affect it significantly. Very fatty meals can delay onset. Alcohol in moderate amounts is usually compatible, but excess worsens erectile function on its own.
The EU product information says to take it 25 to 60 minutes before sex. In a RigiScan study, vardenafil 20 mg produced erections rigid enough for penetration in some men as early as 15 minutes after the dose, and the overall response became statistically better than placebo at 25 minutes. The European Association of Urology describes vardenafil as effective from 30 minutes, with about one in three men achieving a satisfactory erection within 15 minutes. A high-fat meal pushes the peak blood level back by roughly an hour, so onset can feel later.
No. Bioequivalence studies showed the 10 mg orodispersible tablet is not bioequivalent to the 10 mg film-coated tablet, and the EU product information says it must not be used as an equivalent. Average exposure was 21% to 29% higher in middle-aged and elderly patients, and 44% higher in young healthy volunteers. The orodispersible tablet has to be taken without any liquid, because water cuts absorption by 29%, and its maximum is 10 mg a day. Only your prescriber should switch you between the two forms.
That is a decision for your prescriber. Single doses of 10 mg and 80 mg of vardenafil lengthened the QTc interval by an average of 8 and 10 milliseconds. The EU product information says medicines that prolong QTc, vardenafil included, are best avoided in people with relevant risk factors such as low blood potassium, congenital QT prolongation, or treatment with class IA antiarrhythmics like quinidine and procainamide, or class III ones like amiodarone and sotalol. Nitrates for angina are an absolute contraindication with any dose.
Write to your doctor in the private chat in your account: describe what you notice and when it started. The doctor can adjust the plan, pause it or suggest another option. If you have severe symptoms such as difficulty breathing, swelling of the face or chest pain, call 112 or go to an emergency department straight away.
It depends on what you take. List every medicine, supplement and herbal product in the questionnaire, including ones you use only occasionally. The doctor checks for interactions before prescribing, and your pharmacist checks again when you collect Vardenafil 5/10/20mg.
Depending on your case, the doctor can consider a different medicine or dosing pattern, or recommend an in-person urologist, a sexual health clinic or psychosexual therapy. If a heart condition or another health issue needs checking first, the doctor tells you before prescribing anything.
If the medicine does not work as expected or causes side effects, write to your doctor in the private chat. The doctor can review the dose or the option chosen. Tell the doctor about any new health condition or new medicine before you use it again.
Yes. Hi-Doctor runs 100 % online across the EU, so if you live in Vienna you can fill in the questionnaire and receive the medical review without travelling. The electronic prescription issued by the licensed doctor is valid in any EU pharmacy under Directive 2011/24/EU; outside Spain, the pharmacist dispenses the locally marketed equivalent of the same active ingredient.
Yes. All communication happens in the private chat of your account, GDPR-compliant. The doctor treats discretion as a core of the service and there is no history visible outside your consultation.
The private electronic prescription (Receta Médica Privada Electrónica) is issued by a licensed doctor in Spain. It is a PDF carrying every field required by EU Directive 2011/24/EU (patient, prescriber with country of registration, active ingredient, dose), which makes it legally recognised across all 27 EU member states. In Spanish pharmacies it is dispensed from the QR; outside Spain, the pharmacist dispenses the locally marketed equivalent of the same active ingredient.

Medicine information and safety

How does Vardenafil 5/10/20mg work?

Arousal releases nitric oxide. Sexual stimulation makes nerves and blood vessel linings in the penis release nitric oxide. Nitric oxide switches on an enzyme called guanylate cyclase, which builds up a messenger chemical known as cyclic GMP inside the smooth muscle of the erectile tissue.

Cyclic GMP opens the blood flow. Cyclic GMP relaxes that smooth muscle, so the arteries widen and blood flows into the corpus cavernosum, the two spongy chambers that run along the penis. That inflow is what produces an erection. Your body then steadily breaks the cyclic GMP down again.

Vardenafil blocks the clean-up enzyme. Vardenafil blocks PDE5, the enzyme that breaks cyclic GMP down and the most abundant one in penile tissue. Cyclic GMP therefore lasts longer and the relaxation is stronger. Sexual stimulation is still required, because without it no nitric oxide is released in the first place.

How to use Vardenafil 5/10/20mg

Take it before sex, not daily. Vardenafil is taken only when you plan to have sex, roughly 25 to 60 minutes beforehand. It is not a daily tablet. The most you should take is one dose in any 24 hours.

Arousal is still needed. The tablet does not create an erection by itself. Sexual stimulation is required, because your body has to release nitric oxide first before vardenafil has anything to act on. Without arousal, nothing happens.

Food is fine, fat delays it. Film-coated tablets can be taken with or without food. A high-fat meal, around 57% fat, slows absorption and pushes the peak blood level back by about an hour, so the onset can feel later than usual.

Skip grapefruit. Avoid grapefruit and grapefruit juice while you are taking vardenafil. Grapefruit weakly blocks the gut enzyme that clears the drug, which can push blood levels up. The EU product information advises avoiding the combination.

Orodispersible tablets: no drink. If you are prescribed the 10 mg orodispersible tablet, place it on your tongue with no liquid at all, then swallow once it has dissolved. Taken with water, absorption falls by 29%.

Do not swap 10 mg forms. The 10 mg orodispersible tablet is not bioequivalent to the 10 mg film-coated tablet, so the two are not interchangeable milligram for milligram. Only your prescriber should move you between them.

Give it a fair trial. If the first attempt disappoints, tell your prescriber rather than giving up. Dose, timing and enough stimulation all matter, and the dose can be raised to 20 mg or lowered to 5 mg.

List every medicine you take. Tell your prescriber about all your medicines, including nitrate sprays or tablets for angina, poppers, HIV treatments, antifungals and heart-rhythm drugs. Several of these combinations are unsafe and change what can be prescribed.

Do not use Vardenafil 5/10/20mg if

  • You take nitrates or nitric oxide donors in any form, including amyl nitrite poppers
  • You take riociguat or another guanylate cyclase stimulator
  • You already take another PDE5 inhibitor or other erectile dysfunction treatment
  • You take an HIV protease inhibitor such as ritonavir or indinavir
  • You are over 75 years old and take oral ketoconazole or itraconazole
  • You have congenital long QT syndrome, or take quinidine, procainamide, amiodarone or sotalol
  • You have lost sight in one eye from NAION, or have an inherited retinal disorder
  • You have severe liver impairment (Child-Pugh C), or kidney failure needing dialysis
  • You had a stroke or heart attack in the past 6 months, or have unstable angina
  • You have severe heart failure, or blood pressure below 90/50 mmHg

Medicines and substances that interact

  • Nitrates and nitric oxide donors (GTN spray, isosorbide, poppers): Can cause a sudden, unpredictable and dangerous fall in blood pressure Absolute contraindication, so the prescriber will not issue vardenafil at all
  • Riociguat and other guanylate cyclase stimulators: Adds to the blood-pressure-lowering effect and can cause symptomatic hypotension Contraindicated, so the prescriber considers a different option entirely
  • Other PDE5 inhibitors or other erectile dysfunction treatments: Combinations have not been studied, and add to the blood-pressure and priapism risk Not recommended, so the prescriber keeps you on one treatment only
  • Class IA and III heart-rhythm drugs (quinidine, procainamide, amiodarone, sotalol): Vardenafil itself lengthened the QTc interval by about 8 msec at 10 mg Best avoided under the EU label; the prescriber reviews QT risk first
  • HIV protease inhibitors (ritonavir, indinavir): Ritonavir raised vardenafil exposure 49-fold and indinavir raised it 16-fold Contraindicated, so the prescriber will not combine them
  • Oral ketoconazole and itraconazole: Ketoconazole 200 mg raised vardenafil exposure roughly 10-fold Should be avoided, and is contraindicated in men over 75 years
  • Erythromycin and clarithromycin: Erythromycin raised vardenafil exposure about 4-fold The prescriber caps the vardenafil dose at 5 mg
  • Alpha-blockers (tamsulosin, alfuzosin, terazosin, doxazosin): Both widen blood vessels, so blood pressure can drop and cause fainting Start at 5 mg only once stable on the alpha-blocker, separating doses
