Vardenafil Orodispersible Tablets (ODT) Explained
Vardenafil orodispersible tablets, often shortened to ODT, are a UK-licensed form of vardenafil that dissolves on the tongue without water. They contain 10mg of vardenafil and are used to treat erectile dysfunction in adult men.
Despite sharing the same 10mg label as the standard film-coated tablet, the two are not interchangeable, because regulatory testing has shown they are not bioequivalent.
This guide explains what vardenafil ODT actually is, how it genuinely differs from the standard tablet, how to take it, what food and safety precautions apply, and what the 10mg label does and does not tell you about switching between the two formats.
For adults considering prescription vardenafil tablets through an online consultation, these distinctions matter, because choosing, taking or switching between the two formats should be based on clinical assessment rather than the dose label alone.
What Is Vardenafil ODT?
Vardenafil orodispersible tablets are a licensed UK formulation designed to dissolve on the tongue without needing water. "Orodispersible" describes that dissolving property, and ODT is simply the shorthand.
It is a genuine, separately licensed product rather than an unusual or unlicensed variant. The branded version is Levitra orodispersible.
Vardenafil ODT is available at a single strength, 10mg. That is different from the standard film-coated tablet, which is licensed at 5mg, 10mg and 20mg, giving a prescriber more room to adjust the strength than the orodispersible version allows.
The format exists as an alternative for people who may find a dissolving tablet more convenient than swallowing one with water, not as an upgrade or a different treatment altogether. The active ingredient is the same vardenafil used in the film-coated tablets, formulated differently to change how it is taken and how it is absorbed.
How It Differs From the Standard Tablet
The most important difference is not the dissolving method itself, but what regulatory testing has shown about how the two formats behave in the body.
Vardenafil 10mg orodispersible tablets have been shown not to be bioequivalent to vardenafil 10mg film-coated tablets, meaning they do not produce the same levels of the medicine in the body despite containing the same labelled dose. Because of that, the orodispersible formulation should not be treated as an equivalent substitute for the 10mg film-coated tablet.
| Feature | Film-coated tablet | Orodispersible tablet |
|---|---|---|
| Strengths available | 5mg, 10mg, 20mg | 10mg only |
| How it is taken | Swallowed whole with water | Placed on the tongue, dissolves without water |
| Bioequivalence to the other format | Not equivalent to the 10mg ODT | Not equivalent to the 10mg film-coated tablet |
| Combining the two formats | Not recommended together | Not recommended together |
That table reflects a genuine regulatory finding rather than a general assumption about tablet formats. It is specific to vardenafil, and specific to the 10mg comparison, since that is the only strength where both formats exist.
Why the Same Milligrams Does Not Mean the Same Dose Reaching Your System
It is a reasonable assumption that two products labelled with the same milligram strength would work identically, but that is not always true when the formulation itself changes.
Different formulations can be absorbed differently, releasing the active ingredient at a different rate or in a different overall amount, even when the labelled strength is identical. That is exactly why regulators require bioequivalence testing before treating two formulations of the same medicine as interchangeable.
Vardenafil's 10mg ODT and 10mg film-coated tablet, having failed that test against each other, are treated as genuinely separate products rather than two versions of the same dose.
This is worth understanding if you have ever wondered why a 10mg label does not automatically mean two products are the same. It is also a reason to be cautious of any general assumption that dissolving and swallowed versions of a medicine will always behave identically. Some do. This specific comparison has been directly tested and shown not to.
How It Works
Vardenafil improves erectile function by blocking the breakdown of cGMP, a signalling molecule that relaxes the smooth muscle in blood vessels. That relaxation increases blood flow to the penis during sexual stimulation.
Sexual stimulation is still required for it to work. The tablet does nothing on its own.
How to Take It
Vardenafil ODT is placed on the tongue, where it dissolves with saliva and without liquid. That is the defining practical difference from the film-coated tablet, which is swallowed whole.
Handle the tablet with dry hands immediately before taking it, since orodispersible tablets can be fragile and are designed to disintegrate quickly once exposed to moisture.
Take the tablet directly from its packaging just before use, rather than removing it in advance, because exposure to moisture in the air can affect it before you are ready. That is a handling point specific to the orodispersible format and does not apply to the film-coated tablet.
Timing follows the same general principle as standard vardenafil. It is usually taken about 25 to 60 minutes before sexual activity, and its terminal half-life is around 4 to 5 hours, which should not be interpreted as a fixed duration of effect.
Can You Switch Between the Two Formats?
Switching is a decision for your prescriber, not something to do independently based on convenience or preference. Because the two are not bioequivalent, moving from one to the other is not a like-for-like substitution, even at what looks like the same milligram strength.
Combining the two formats on the same occasion, taking both the film-coated and the orodispersible tablet together, is specifically not recommended, because the safety and effectiveness of doing so have not been studied.
That is a distinct point from the general rule against combining different PDE5 inhibitors, and it applies here even though both products contain the same active ingredient, because they are different formulations of it.
If you are currently taking one format and are curious about the other, that is a reasonable question to raise at your next assessment or review, rather than something to try alongside your current treatment. Your prescriber can confirm whether switching is appropriate and what to expect from the change.

Food, Alcohol and Other Medicines
Vardenafil generally has a milder food effect than sildenafil, though food can still affect absorption.
Avoid grapefruit and grapefruit juice close to your dose, since this can increase the level of vardenafil in your body. That consideration applies across the PDE5 inhibitor class generally.
Excessive alcohol can add to vardenafil's blood-pressure-lowering effect and increase the chance of feeling light-headed, regardless of which format you are taking.
Check with a prescriber or pharmacist about other medicines, because interactions can affect both safety and effectiveness.
Never take more than one dose of vardenafil in any 24-hour period, whichever format that dose comes in. That limit applies to the medicine itself rather than to each format separately, which is another reason combining the two is not appropriate.
These considerations are shared across both formats, because they relate to how the active ingredient behaves in the body rather than to the dissolving method.
Safety and Side Effects
Vardenafil has a measurable effect on the QT interval, part of the heart's electrical cycle, which is why it is generally avoided in people with congenital QT prolongation or those taking certain antiarrhythmic medicines. That consideration applies to vardenafil as an active ingredient and is not specific to one format.
Tell your prescriber before use if you have angina, a recent heart attack or stroke, low or high blood pressure, chest pain, liver problems, or an allergy to vardenafil or any of the tablet's ingredients.
If you take an alpha blocker, vardenafil is generally only started once you are stable on that therapy, and your prescriber may start you at the lowest recommended strength.
Tolerability of the maximum 20mg strength may also be lower in patients aged 65 and over, which a prescriber takes into account when confirming strength, although that relates to the film-coated tablet's dose range rather than the single-strength ODT.
The most commonly reported side effect with vardenafil, in either format, is headache, generally mild to moderate. Flushing and dizziness are also common. Most side effects reported in clinical use have been described as transient and mild to moderate, though your own response is what matters and is worth discussing with your prescriber if anything feels different from what you expected.
The patient information leaflet contains a complete list of side effects. Seek emergency medical attention if you experience an erection lasting longer than four hours, or a sudden loss of vision or hearing. These are rare but serious, and apply regardless of which format you have taken.
Is There a Discount or Coupon?
No. Vardenafil ODT is a prescription-only medicine in the UK, and UK rules restrict how prescription-only medicines can be advertised to the public, so promotional claims and discount offers need to comply with those requirements.
The current price for your order is shown once you begin your online consultation, before you are asked to pay anything, and reflects the actual strength and quantity relevant to you rather than a generic promotional figure.
Getting Vardenafil Through EveryDayMeds
Vardenafil is available through an online consultation with UK-registered prescribers, including both the film-coated tablet and, where appropriate, the orodispersible format.
Your clinical assessment covers your medical history, current medicines and any relevant heart health considerations, which allows a prescriber to confirm which format and strength is appropriate for you. Medicine is dispensed by a GPhC-registered pharmacy and sent out in discreet packaging.
Vardenafil is licensed for adult men and is not indicated for use by women.
Treatment suitability depends on an individual clinical assessment, and results vary between individuals. This medicine should only be used under the supervision of an appropriately qualified prescriber.
If you have a preference between the two formats, raise it during your assessment so your prescriber can confirm whether it is appropriate for your circumstances, rather than assuming the two are interchangeable based on the label alone.
