How to Use Vardenafil: Step-by-Step Instructions

Using vardenafil correctly is straightforward: swallow the tablet whole with water 25 to 60 minutes before you expect to need it, do not crush or split it, and never take more than one dose in any 24-hour period.

Timing and dosing both matter, because they affect how well the medicine works and how safely you use it.

Vardenafil is a prescription medicine rather than something available over the counter, so always follow your prescription label, the patient information leaflet, and any advice from your prescriber.

This page covers how to take it, food and alcohol advice, first-time use, storage, what to do if you have not taken it in time, and when to get urgent medical help.

Key things to know

• Swallow vardenafil tablets whole with water. Do not crush, split or dissolve them
• Take it 25 to 60 minutes before you expect to need it
• It can be taken with or without food, although a high-fat meal may delay how quickly it starts to work
• Physical and mental stimulation are still required. It does not work on its own
• Take no more than one dose in any 24-hour period

How to Take It

Swallow the tablet whole with a glass of water.

Standard film-coated tablets should not be crushed, split or dissolved, since the coating helps control how the medicine is released and absorbed.

Always check the prescription label and read the patient information leaflet before use, and make sure the blister pack is intact.

When to Take It

Take vardenafil 25 to 60 minutes before you expect to need it, so it has time to be absorbed.

The timing has some flexibility, but the medicine needs to be in your system before it can support the erectile response.

Vardenafil is not taken on a fixed schedule. It is taken as needed, with reasonable timing beforehand.

With or Without Food

Vardenafil is not significantly affected by food in the way some options are, so you do not need to plan closely around meals.

A high-fat meal can still slow how quickly it is absorbed, but that is generally a mild consideration rather than something requiring careful planning.

Ask your prescriber about grapefruit and grapefruit juice, which can affect how the medicine is processed and increase the risk of side effects.

Alcohol

Moderate alcohol is generally not a significant concern, but larger amounts can add to vardenafil's mild effect on blood pressure.

Alcohol can also affect arousal independently of the medicine, so it may reduce how well treatment appears to work.

If you are planning to drink, keeping it moderate is the sensible approach.

What Not to Do

Do not take more than one dose in any 24-hour period, and follow the dose your prescriber has given you.

Do not combine vardenafil with another PDE5 inhibitor or other erectile dysfunction treatment without prescriber advice, whether on the same day or close together. That raises the risk of side effects without any established benefit.

Do not take it with nitrate medicines or nicorandil, which are used to treat angina. The combination can cause a dangerous drop in blood pressure.

Do not take it with guanylate cyclase stimulators. Alpha blockers also increase the risk of low blood pressure and need reviewing before treatment.

Declare all your other medicines before treatment, including anything bought without a prescription and any supplements. If you take a medicine that affects how vardenafil is processed, your prescriber may advise a lower dose.

If You Have Not Taken It in Time

Do not take an extra dose to compensate.

A higher dose should only ever be taken if a prescriber has advised it, and the one-dose limit applies regardless of how the timing has worked out.

Taking It for the First Time

The instructions above apply in the same way.

Before starting, make sure your prescriber has reviewed your medical history and any health conditions that could affect suitability. That matters particularly for heart-related conditions, including heart disease, high blood pressure or a previous heart attack.

The recommended dose varies between people. The usual starting dose is 10mg, and some people are advised to start lower, at 5mg, based on factors including age, other medicines and liver function.

It is also worth knowing that a single occasion is not always representative. Trying it correctly on a few separate occasions gives a more reliable picture of how it works for you.

Storage

Store vardenafil somewhere cool and dry, away from direct sunlight, following the specific instructions on your packaging.

Keep it in its original packaging until you are ready to take it, and out of reach of children.

If Something Feels Wrong

Seek emergency medical attention immediately if you experience an erection lasting more than four hours, signs of an allergic reaction, sudden loss of vision in one or both eyes, or a sudden decrease in hearing.

Headache is the most commonly reported side effect, affecting up to 1 in 10 men taking vardenafil.

For side effects that are persistent or concerning but not an emergency, contact a pharmacist or your prescriber for advice rather than continuing to use it as normal.
