How Levitra Professional works (mechanism of action)
Vardenafil belongs to a group of medicines called PDE5 inhibitors (phosphodiesterase type 5 inhibitors).
During sexual arousal, the body releases nitric oxide, which helps relax the smooth muscle in the penis and increases blood flow. PDE5 is an enzyme that breaks down a chemical messenger involved in this process.
Vardenafil helps block PDE5, allowing the natural erection process to work more effectively. The result is improved ability to achieve and maintain an erection. It does not create an erection without sexual stimulation.
Pharmacokinetics: how the body absorbs and processes it
Understanding typical behaviour in the body can help you time your dose and manage side effects.
- Absorption: Vardenafil is absorbed from the gastrointestinal tract. Peak levels are usually reached within a few hours after taking the tablet.
- Onset of effect: Many people notice effects within about 30–60 minutes, though timing can vary.
- Duration: Effects may last for several hours. The medicine is designed to be taken before planned sexual activity.
- Metabolism: It is processed mainly by the liver (involving CYP enzymes).
- Elimination: Metabolites are cleared primarily through the liver/bile and partly via the kidneys.
Individual differences—such as age, other medical conditions, and other medicines—can affect how quickly it works and how long it lasts.
Typical use and when to take it (timing)
When it should be used
Levitra Professional is used on-demand for erectile dysfunction. It is not typically taken daily for continuous effect.
General timing guidance
- Take the tablet before sexual activity.
- Many people take it about 30 to 60 minutes beforehand.
- Some may find it works better at a different time. You should follow the instructions from your healthcare professional and the leaflet for your specific tablet strength.
- Do not take more than the recommended dose in 24 hours.
If you have not tried it before, consider starting with a test dose on a day when you can see how you respond.
Indications: who Levitra Professional is for
Vardenafil is indicated for the treatment of erectile dysfunction in adult men. ED can occur due to many factors, including vascular health, diabetes, hormonal changes, stress, or side effects from other medicines.
Levitra Professional is intended for men with ED. It is not suitable for everyone. Do not use it if you have been advised against PDE5 inhibitors or if it is contraindicated due to your medical history.
Dosing: recommended approach in adults
Dosing can vary depending on age, kidney/liver function, and other medicines. Always follow the leaflet and any guidance given by a healthcare professional.
General adult dosing principles
- Take the tablet only when needed for sexual activity.
- Start with the lowest effective dose recommended for you.
- Typical regimens involve one dose per day at most (as per standard product guidance).
- If a dose doesn’t work for you, do not increase without medical advice—talk to a pharmacist or clinician.
Special populations (important)
- Older men: You may be more sensitive to side effects. Lower starting doses are often considered.
- Kidney impairment: Dose adjustments may be needed.
- Liver impairment: Dose adjustments may be needed and some strengths may be unsuitable.
- Use with certain medicines: Some drug combinations significantly raise vardenafil levels and require caution.
If you are unsure which strength is appropriate, ask us or a healthcare professional. The leaflet in your pack will include the exact dosing instructions for that presentation.
Food interactions: what to eat and what to avoid
Food can change how quickly the medicine is absorbed. In general, a heavy or high-fat meal can slow the onset of action.
- Light meals: Usually less likely to delay the effect.
- Heavy or fatty meals: May delay the time to onset. If using after a large meal, you may need to take it earlier.
- Consistency: If possible, keep your eating pattern similar when testing timing.
You can generally take vardenafil with or without food, but timing may affect how quickly it works. Follow the leaflet for advice specific to your tablet strength.
Alcohol and Levitra Professional
Alcohol can affect sexual performance and can increase side effects such as dizziness or headache. While moderate alcohol may be tolerable for some men, it is still important to use caution.
- Moderate intake: May be acceptable, but monitor how you feel.
- Heavy drinking: Increases the risk of reduced erection quality and dizziness due to blood pressure effects.
- Safety: Avoid activities requiring alertness if you feel light-headed.
If you notice flushing, palpitations, faintness, or severe dizziness, stop alcohol and seek advice promptly.
Medicine interactions: important safety considerations
Vardenafil can interact with other medicines, mainly those affecting blood vessels and those that change how vardenafil is broken down in the body. Some combinations can cause a dangerous drop in blood pressure or other serious effects.
Medicines that must be avoided
- Nitrates (for chest pain/angina), such as glyceryl trinitrate (GTN), isosorbide mononitrate/dinitrate: combining these with PDE5 inhibitors can cause a major fall in blood pressure.
- Riociguat: a medicine for pulmonary hypertension—this combination can also significantly lower blood pressure.
Blood pressure and alpha-blocker interactions
- Alpha-blockers (often used for prostate symptoms, e.g., tamsulosin, doxazosin) can also lower blood pressure. Combined use may increase the risk of dizziness or fainting.
- If you use an alpha-blocker, dosing schedules and starting doses must be handled carefully by a clinician.
Other PDE5 inhibitors or erectile dysfunction medicines
- Do not take vardenafil with other PDE5 inhibitors (e.g., sildenafil, tadalafil) or with similar ED medicines.
Strong CYP3A4 inhibitors (raise vardenafil levels)
Some medicines can increase vardenafil exposure, increasing side effects and potentially causing complications. Examples include certain:
- antifungals (e.g., ketoconazole, itraconazole)
- antibiotics used for some infections (e.g., clarithromycin)
- HIV medicines (certain protease inhibitors)
If you take any of these, do not guess—ask a pharmacist or clinician for interaction guidance.
“Lifestyle” interactions that still matter
- Grapefruit products: may increase levels in some people due to effects on metabolism. Consider avoiding.
- Smoking: can affect blood vessel health and ED overall, potentially reducing effectiveness.
If you are unsure whether a medicine interacts, keep a list of your current medicines and ask us for advice.
Safety profile: common and serious side effects
Common side effects
Many people tolerate vardenafil well. However, side effects may occur, especially early in treatment or with higher doses.
- Headache
- Flushing (warmth, redness)
- Indigestion or nausea
- Stuffy or runny nose
- Dizziness
- Back pain or muscle aches (in some men)
- Occasional visual disturbances (e.g., mild colour tinge)
Serious side effects – seek urgent medical advice
Contact urgent medical services or seek prompt advice if you experience:
- Chest pain or symptoms of serious heart problems
- Prolonged erection (priapism): an erection lasting longer than recommended (commonly stated as 4 hours)
- Sudden vision loss or significant eye pain
- Sudden hearing changes (sometimes with dizziness/ringing in ears)
- Severe dizziness or fainting
- Signs of a severe allergic reaction (e.g., swelling of face/lips, difficulty breathing)
Who should be extra cautious
- Men with significant heart disease or unstable angina
- Men with low blood pressure or conditions that predispose to fainting
- Men taking interacting medicines (particularly nitrates or certain drugs that change metabolism)
- Men with certain eye conditions (seek professional advice)
Practical use tips for best results
- Plan ahead: take it at the right time before sex (often 30–60 minutes; adjust based on your experience).
- Use sexual stimulation: the medicine supports the process but does not replace arousal.
- Avoid heavy meals right beforehand: if you notice delays in effect, try taking it on a lighter stomach.
- Don’t exceed the maximum frequency: more is not always better and raises side-effect risk.
- Keep alcohol moderate: alcohol can reduce erection quality and increase dizziness.
- Stay hydrated: dehydration can make headaches and dizziness worse.
- Track what works: note your dose, timing, food, and side effects to refine future attempts (share notes with a clinician if needed).
When Levitra Professional may not work as expected
ED can have multiple causes. If vardenafil is not effective after appropriate timing and a suitable dose:
- there may be an underlying condition (e.g., diabetes, vascular disease, hormonal issues)
- dose adjustment might be needed under professional guidance
- interaction with another medicine may be reducing effectiveness or increasing risk
- psychological factors or stress can also contribute
Persistent ED deserves assessment. It can be a marker of cardiovascular risk.
Alternative options (other treatments for ED)
If vardenafil isn’t suitable or doesn’t help, there are alternatives. Your best choice depends on your health, other medicines, and personal preference.
Other PDE5 inhibitors
- Sildenafil (e.g., for ED)
- Tadalafil (often has a longer window for effect)
- Other vardenafil presentations (different strengths or formulations)
Non-PDE5 approaches
- Lifestyle measures: exercise, weight management, smoking cessation, limiting alcohol
- Psychological support if anxiety or performance stress is a factor
- Other medical treatments for ED (e.g., options used in specialist settings)
If you’re not responding well, a clinician can help determine the cause and choose the safest alternative.
