What Is Vardenafil and How Does It Work?

Vardenafil is a prescription medicine used to treat erectile dysfunction in adult men. It belongs to a group of medicines called PDE5 inhibitors, which work by relaxing blood vessels in the penis, allowing increased blood flow when you're sexually aroused [5]. Vardenafil does not cause an erection on its own—sexual stimulation is always needed for the medicine to work.

Levitra is the original branded version of vardenafil, developed and marketed by Bayer. Generic vardenafil contains exactly the same active ingredient at the same strengths (5mg, 10mg, and 20mg) and is manufactured to the same strict quality standards required by the UK Medicines and Healthcare products Regulatory Agency (MHRA) [12]. Once a medicine's patent expires, other manufacturers can produce generic versions that are bioequivalent to the original brand, meaning they deliver the same amount of active ingredient into your bloodstream at the same rate.

Both generic and branded vardenafil are taken about 25 to 60 minutes before sexual activity, and the effect can last for around four to five hours [5]. The maximum recommended dose is once per day. Because vardenafil and all PDE5 inhibitors can interact with certain medicines—particularly nitrates, nicorandil, and some blood pressure medicines—a prescriber will always review your medical history and current medications during an online consultation before approving treatment.

Vardenafil Generic vs Brand: Onset and Duration

One of the most common questions is whether generic vardenafil works as quickly as branded Levitra. The answer is yes: both formulations typically start working within 25 to 60 minutes of taking the tablet, and both require sexual stimulation to produce an erection [5]. Some men may notice an effect sooner, especially on an empty stomach, but individual response times can vary.

The duration of action is also the same for both generic and branded vardenafil. Clinical studies show that vardenafil can remain effective for around four to five hours after taking a dose [5]. This does not mean you will have an erection for that entire time—it means the medicine is available in your system to help you achieve an erection when you are sexually stimulated during that window.

Because the active ingredient, dose, and absorption profile are identical, there is no clinical reason to expect a difference in how fast generic vardenafil works compared to Levitra, or how long the effect lasts. Any perceived difference is more likely due to individual variation, what you've eaten, or psychological factors rather than the formulation itself.

Does Food Affect Vardenafil?

High-fat meals can delay the absorption of vardenafil, meaning it may take longer to work if you've just eaten a large, fatty meal [5]. This applies equally to both generic vardenafil and branded Levitra. For the fastest onset, it's generally recommended to take vardenafil on an empty stomach or after a light meal. However, vardenafil is less affected by food than sildenafil (Viagra), so moderate meals are usually fine.

When to get urgent help

• Erection lasting more than 4 hours (priapism)—go to A&E immediately
• Sudden loss of vision in one or both eyes—stop taking vardenafil and seek urgent medical help
• Sudden decrease or loss of hearing—stop the medicine and see a doctor the same day
• Chest pain during or after sex—call 999; do not take nitrate medicines if you have used vardenafil in the past 24 hours
• Severe allergic reaction (rash, swelling of face or throat, difficulty breathing)—call 999

Call 999 or go to A&E in an emergency, or contact NHS 111 for urgent advice.

Available Strengths and Dosing for Vardenafil Generic vs Brand

Both generic vardenafil and branded Levitra are available in three strengths: 5mg, 10mg, and 20mg [5]. The usual starting dose for most men is 10mg, taken about 25 to 60 minutes before sexual activity. Depending on how well the medicine works and whether you experience any side effects, your prescriber may adjust the dose up to 20mg or down to 5mg.

The 5mg dose is often used for men who are taking certain other medicines that can interact with vardenafil, such as alpha-blockers for prostate symptoms or blood pressure, or for those who experience side effects at higher doses [5]. The 20mg dose is the maximum and should not be exceeded. You should not take more than one dose of vardenafil in a 24-hour period, regardless of whether you choose generic or branded.

At Cured Pharmacy, generic vardenafil is available at £16.95 for a pack (first order with code Ednew: £13.56), following an online consultation reviewed by a UK prescriber. All strengths require a prescription, and the prescriber will recommend the most appropriate dose based on your medical history, current medications, and any previous experience with ED treatments.

Side Effects: Generic Vardenafil vs Brand

Because generic vardenafil and branded Levitra contain the same active ingredient at the same strength, they share the same side effect profile [5]. Common side effects include headache, flushing (redness or warmth in the face or chest), nasal congestion, indigestion, and dizziness. These effects are usually mild and temporary, and not everyone experiences them.

Less common but more serious side effects can occur with any PDE5 inhibitor, including vardenafil. If you experience an erection lasting more than four hours (priapism), sudden loss of vision in one or both eyes, or sudden decrease or loss of hearing, stop taking the medicine and seek urgent medical help [5]. Chest pain during or after sex should also be treated as a medical emergency—do not take nitrate medicines such as GTN spray if you have used vardenafil within the past 24 hours, as the combination can cause a dangerous drop in blood pressure.

Some men report differences in side effects between generic and branded medicines, but these are usually due to the inactive ingredients (such as fillers, binders, or coatings) rather than the active drug itself. If you have known allergies to specific excipients, check the patient information leaflet or speak to a pharmacist. In clinical terms, the safety and tolerability of generic vardenafil are equivalent to branded Levitra [12].

Who Should Not Take Vardenafil?

Vardenafil is not suitable for everyone. You must not take vardenafil if you are using nitrates (such as GTN spray, isosorbide mononitrate, or isosorbide dinitrate), nicorandil, riociguat, or recreational drugs known as 'poppers' (amyl or alkyl nitrites), as the combination can cause a severe and potentially life-threatening drop in blood pressure [5]. Vardenafil is also not recommended if you have severe heart or liver problems, very low blood pressure, a recent stroke or heart attack, or a history of non-arteritic anterior ischaemic optic neuropathy (NAION), a rare cause of sudden vision loss [5]. Always disclose your full medical history and all current medicines during your consultation.

Price Comparison: Vardenafil Generic vs Brand in the UK

Price is often the deciding factor when choosing between vardenafil generic vs brand. Generic medicines are typically much less expensive than their branded equivalents because the manufacturers do not have to cover the research, development, and marketing costs associated with bringing a new drug to market. At Cured Pharmacy, generic vardenafil is priced at £16.95 per pack (first order with code Ednew: £13.56), while branded Levitra, when available, is usually significantly more expensive.

It's important to note that a lower price does not mean lower quality. Generic vardenafil must meet exactly the same standards for safety, quality, and efficacy as branded Levitra [12]. The active ingredient is identical, the manufacturing is regulated by the MHRA, and bioequivalence studies confirm that the generic delivers the same therapeutic effect. Choosing a generic can make ongoing treatment more affordable without compromising on effectiveness.

All vardenafil products—generic and branded—require a prescription in the UK. At Cured Pharmacy, you complete an online consultation that is reviewed by a UK-registered prescriber. If approved, your medicine is dispensed by our GPhC-registered pharmacy (GPhC 9012511) and delivered discreetly to your door. The consultation fee is included in the price, and first-time customers can use code Ednew for a discount on their first order.

Which Should You Choose: Generic Vardenafil or Brand?

For most men, generic vardenafil is the practical choice. It offers the same clinical benefits as branded Levitra—same active ingredient, same strengths, same onset and duration—at a lower cost [5][12]. If you have previously used branded Levitra and been satisfied with the results, switching to generic vardenafil is unlikely to make any difference to how well the medicine works or how you tolerate it.

Some men prefer branded medicines for personal reasons, such as familiarity, packaging, or simply peace of mind. If cost is not a concern and you feel more confident with a branded product, that choice is entirely valid. However, from a clinical and regulatory standpoint, there is no therapeutic advantage to choosing branded Levitra over generic vardenafil.

It's also worth considering other PDE5 inhibitors if vardenafil does not suit you. Sildenafil (generic Viagra) is available at Cured Pharmacy from £0.45 per tablet (first order with code Ednew: £0.36) and works in a similar timeframe. Tadalafil (generic Cialis) costs £7.95 (first order with code Ednew: £6.36) and can last up to 36 hours, offering more spontaneity. Avanafil (Spedra) works in as little as 15 to 30 minutes and is priced at £20.95 (first order with code Ednew: £16.76). Your prescriber can help you choose the most suitable option based on your lifestyle, preferences, and medical history.

When to See Your GP

If you are experiencing erectile dysfunction for the first time, it's important to see your GP for a full assessment [1][2]. ED can be an early warning sign of underlying health conditions such as heart disease, diabetes, or high blood pressure. Your GP can arrange blood tests, check your cardiovascular health, and discuss lifestyle factors such as smoking, alcohol, exercise, and stress. Treating the underlying cause—or managing it effectively—can sometimes improve ED without the need for medication, or make ED treatments work better.

In summary

• Generic vardenafil and branded Levitra contain the same active ingredient at identical strengths and work in the same way.
• Both typically start working within 25 to 60 minutes and last around four to five hours.
• Generic vardenafil is significantly cheaper than branded Levitra but delivers the same clinical effect and safety profile.
• High-fat meals can delay the onset of vardenafil, whether generic or branded.
• All vardenafil products require a prescription following a consultation with a UK-registered prescriber.
