How Does Vardenafil Work for Men Over 60?

Vardenafil belongs to a class of medicines called PDE5 inhibitors, which work by relaxing blood vessels in the penis to improve blood flow during sexual arousal [5]. It does not cause an erection on its own—sexual stimulation is still needed for the medicine to work. Vardenafil is available in 5mg, 10mg and 20mg tablets, and the usual starting dose for most men is 10mg, taken about 25 to 60 minutes before sexual activity [5].

For men over 60, the same mechanism applies, but age-related changes in how the body processes medicines may mean vardenafil stays in the system slightly longer. This does not usually cause problems, but it does mean older men should start on the lowest effective dose and only increase if needed and advised by a prescriber [5]. The medicine can be taken a maximum of once a day, and it works best when taken on an empty stomach, as a heavy meal can delay its effect.

Vardenafil typically begins to work within 25 to 60 minutes and its effects can last for around four to five hours, giving a practical window for spontaneous sexual activity [5]. Like all PDE5 inhibitors, it treats the symptoms of erectile dysfunction but does not address the underlying cause, so it is important to discuss any new or worsening ED with a GP, as it can be an early sign of cardiovascular disease or diabetes [1][2].

Is Vardenafil Safe for Men Over 60?

Vardenafil is generally safe for men over 60 when prescribed after a thorough medical assessment, but older age brings a higher likelihood of other health conditions and medications that must be checked for interactions [5]. The most important safety concern is the absolute contraindication with nitrates (such as GTN spray, isosorbide mononitrate or dinitrate) and nicorandil, which are commonly prescribed for angina. Taking vardenafil alongside any of these medicines can cause a dangerous drop in blood pressure and is never safe [5].

Men over 60 are also more likely to take alpha-blockers for prostate symptoms (such as tamsulosin or doxazosin) or blood pressure medicines. Combining vardenafil with alpha-blockers can increase the risk of dizziness or fainting due to low blood pressure, so the prescriber will ensure the patient is stable on the alpha-blocker and start vardenafil at the lowest dose [5]. Other blood pressure medicines can add to the blood-pressure-lowering effect of vardenafil, which is usually manageable but must be declared during the consultation.

Vardenafil is not suitable for men with severe heart failure, unstable angina, recent heart attack or stroke, very low blood pressure, or a history of sudden vision loss (NAION) [5]. Because these conditions are more common in older men, a careful review of medical history is essential. The prescriber will also check for potent CYP3A4 inhibitors (such as ritonavil, ketoconazole or clarithromycin), which can raise vardenafil levels and are often contraindicated or require dose adjustment [5]. All prescription ED treatments at Cured Pharmacy are only supplied after an online consultation reviewed by a UK prescriber.

Common Side Effects in Older Men

The most common side effects of vardenafil include headache, flushing, nasal congestion and indigestion, which can occur at any age [5]. Older men may be more sensitive to side effects such as dizziness, particularly if they are taking other medicines that lower blood pressure. If dizziness occurs, it is important to sit or lie down and avoid driving or operating machinery until it passes. Drinking plenty of water and avoiding heavy alcohol can help reduce side effects, as alcohol can worsen ED and add to the blood-pressure-lowering effect of vardenafil.

What Dosage of Vardenafil Is Right for Men Over 60?

The recommended starting dose of vardenafil for most men, including those over 60, is 10mg taken about 25 to 60 minutes before sexual activity [5]. Depending on how well it works and whether side effects occur, the dose can be adjusted by a prescriber—either reduced to 5mg or increased to a maximum of 20mg. Older men, particularly those with liver or kidney problems or taking certain other medicines, may be advised to start on the lower 5mg dose to minimise the risk of side effects [5].

Vardenafil should be taken no more than once in any 24-hour period, and it is most effective when taken on an empty stomach, as a high-fat meal can delay absorption and reduce effectiveness [5]. Men over 60 should never adjust the dose themselves or take more than prescribed, as this increases the risk of side effects without improving results. If the prescribed dose is not working well, the prescriber can review the treatment plan and consider alternative options or investigate underlying causes of ED.

It is also important to give vardenafil a fair trial—some men find it works better after using it a few times, as confidence and reduced anxiety can improve the response. If vardenafil does not work or causes troublesome side effects, other PDE5 inhibitors such as sildenafil or tadalafil may be more suitable, as individual responses can vary [2][5].

Vardenafil for Men Over 60 Compared to Other ED Treatments

Vardenafil is one of four licensed oral PDE5 inhibitors available in the UK, alongside sildenafil (Viagra), tadalafil (Cialis) and avanafil (Spedra) [2]. All four work in a similar way by increasing blood flow to the penis during sexual arousal, but they differ in how quickly they start to work and how long their effects last. Sildenafil and vardenafil have similar onset times (around 30 to 60 minutes) and durations (four to five hours), while tadalafil can last up to 36 hours, and avanafil may work as quickly as 15 to 30 minutes [3][4][5][6].

For men over 60, the choice between these medicines often depends on lifestyle, other medications and personal preference. Tadalafil's longer duration can offer more spontaneity and is also available as a low daily dose (2.5mg or 5mg) for men who prefer not to plan ahead [4]. Vardenafil and sildenafil are taken on-demand and may be preferred by men who want a shorter duration of action. Avanafil's faster onset can be helpful for those who want more flexibility in timing [6].

Some men find one PDE5 inhibitor works better or causes fewer side effects than another, so it can be worth trying a different option if the first choice is not ideal [2]. The prescriber will consider medical history, current medicines and individual needs when recommending the most suitable treatment. All PDE5 inhibitors require sexual stimulation to work and do not increase libido or treat the underlying cause of ED.

When to Consider Non-Oral Treatments

If oral PDE5 inhibitors such as vardenafil are not suitable or effective, other prescription options include alprostadil cream (Vitaros) applied to the tip of the penis or alprostadil injections (Caverject) [7]. These treatments work differently and can be effective when tablets are contraindicated or have not worked. A vacuum erection device is a non-drug option that can be used alone or alongside other treatments. Your GP or a specialist can discuss these alternatives if needed [2].

Drug Interactions and Vardenafil for Men Over 60

Men over 60 are more likely to take multiple medicines, so checking for drug interactions is a critical part of the prescribing process for vardenafil. The most serious interaction is with nitrates (GTN spray, isosorbide mononitrate, isosorbide dinitrate) and nicorandil, which are used to treat angina. Combining vardenafil with any of these can cause a life-threatening drop in blood pressure and is absolutely contraindicated [5]. Amyl nitrite and alkyl nitrites (poppers) also interact dangerously and must never be used with vardenafil.

Alpha-blockers such as tamsulosin, doxazosin, alfuzosin and terazosin are commonly prescribed for benign prostatic hyperplasia (enlarged prostate) and can cause low blood pressure or dizziness when combined with vardenafil [5]. If you take an alpha-blocker, the prescriber will ensure you are stable on it and start vardenafil at the lowest dose. Other blood pressure medicines can add to the blood-pressure-lowering effect, which is usually manageable but must be declared during the consultation.

Potent CYP3A4 inhibitors—including ritonavir, cobicistat (found in some HIV medicines), Paxlovid (used for COVID-19), ketoconazole, itraconazole and clarithromycin—can significantly raise vardenafil levels in the blood. Vardenafil is often contraindicated or requires careful dose adjustment when these medicines are taken, and the prescriber will check the summary of product characteristics (SmPC) to ensure safety [5]. Conversely, CYP3A4 inducers such as rifampicin, carbamazepine, phenytoin and St John's wort can reduce vardenafil's effectiveness. Grapefruit juice can also raise vardenafil levels and should be avoided. The online consultation at Cured Pharmacy includes a thorough review of all current medicines and supplements to identify any potential interactions.

How to Access Vardenafil for Men Over 60 at Cured Pharmacy

Vardenafil is a prescription-only medicine, which means it can only be supplied after a clinical assessment by a UK-registered prescriber [5]. At Cured Pharmacy, the process is straightforward and discreet: you complete an online consultation that asks about your medical history, current medicines, symptoms and lifestyle. A UK prescriber reviews your answers and, if vardenafil is suitable, approves the prescription. Your medicine is then dispensed by our GPhC-registered pharmacy (GPhC 9012511) and delivered in plain, unmarked packaging.

Vardenafil (generic Levitra) is available at Cured Pharmacy for £16.95, or £13.56 for first orders using the code Ednew. If vardenafil is not the best option for you, the prescriber may recommend an alternative PDE5 inhibitor such as sildenafil (from £0.45, or £0.36 with code Ednew) or tadalafil (from £7.95, or £6.36 with code Ednew). The consultation is free, and you only pay if a prescription is approved and you choose to proceed with treatment.

If you have not been assessed for ED before, or if your symptoms are new or worsening, it is important to see your GP as well, as erectile dysfunction can be an early warning sign of cardiovascular disease, diabetes or other health conditions that need investigation and management [1][2]. Treating ED with vardenafil addresses the symptom but does not replace the need to identify and manage underlying causes. Lifestyle changes such as stopping smoking, reducing alcohol, losing weight if needed, exercising regularly and managing stress can all improve erectile function and overall health [1][2].

What to Expect During Your Consultation

The online consultation will ask about your general health, heart and blood pressure history, current medicines (including over-the-counter and herbal products), and any allergies. You will also be asked about the nature and duration of your erectile difficulties. Answer all questions honestly and completely, as this ensures the prescriber can make a safe and appropriate decision. If any information is unclear or further assessment is needed, the prescriber may ask follow-up questions or advise you to see your GP before starting treatment.
