What is vardenafil and how does it work?

Vardenafil is a prescription medicine licensed in the UK to treat erectile dysfunction (ED) in adult men [5]. It belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors, which also includes sildenafil (Viagra), tadalafil (Cialis), and avanafil (Spedra) [2].

Vardenafil works by relaxing the blood vessels in the penis, allowing more blood to flow into the area when you are sexually aroused [5]. This increased blood flow helps you get and keep an erection suitable for sexual activity. It's important to understand that vardenafil will not work without sexual stimulation—it is not an aphrodisiac and does not increase sexual desire.

Vardenafil is usually taken about 25 to 60 minutes before sexual activity, and the effect can last for several hours [5]. The usual starting dose is 10 mg, which your prescriber may adjust depending on how well it works for you and whether you experience any side effects. The maximum recommended dose is 20 mg, and you should not take more than one dose in 24 hours.

What is ipratropium and how does it work?

Ipratropium is an inhaled medicine used to treat breathing problems caused by chronic obstructive pulmonary disease (COPD), asthma, and other lung conditions. It belongs to a class of medicines called anticholinergics (also known as antimuscarinics), which work by relaxing and opening the airways in your lungs, making it easier to breathe.

Ipratropium is usually inhaled through a metered-dose inhaler or nebuliser, and it works locally in the lungs. Because it is inhaled rather than swallowed, very little of the medicine enters your bloodstream, which means it has minimal effects on other parts of your body. This local action is one reason why ipratropium is unlikely to interact with medicines that work elsewhere in the body.

Common brand names for ipratropium include Atrovent and Respontin. It is often used regularly to prevent breathlessness, or as needed when symptoms occur. Some people use combination inhalers that contain ipratropium alongside other medicines such as salbutamol (a beta-agonist bronchodilator).

Can you take vardenafil and ipratropium together?

No major interaction between vardenafil and ipratropium is commonly reported in the medical literature or drug interaction databases. These two medicines work through completely different mechanisms and in different parts of the body: vardenafil acts on blood vessels in the penis by inhibiting the PDE5 enzyme, while ipratropium works locally in the lungs by blocking muscarinic receptors in the airways.

Because ipratropium is inhaled and has minimal systemic absorption (very little enters the bloodstream), it is unlikely to affect how vardenafil works or increase the risk of side effects. Similarly, vardenafil does not interfere with the way ipratropium opens your airways. This means that, for most men, taking vardenafil for erectile dysfunction while using ipratropium for a respiratory condition should not pose a safety concern.

That said, it is essential to declare all your medicines—including inhalers, over-the-counter treatments, and herbal supplements—when you request an ED treatment. Your prescriber will review your full medical history and current medicines to ensure vardenafil is safe and appropriate for you. If you have any concerns about using these medicines together, discuss them with your GP, pharmacist, or the prescriber during your online consultation.

Why your prescriber reviews all your medicines

Even when no major interaction is expected, your prescriber needs to see the full picture of your health. Some medicines can interact with vardenafil in ways that require dose adjustments or extra caution. For example, medicines that lower blood pressure (such as some treatments for high blood pressure or an enlarged prostate) can add to the blood-pressure-lowering effect of vardenafil, potentially causing dizziness or fainting [5]. Other medicines, particularly those that affect liver enzymes, can change how quickly your body breaks down vardenafil, making it stronger or weaker than expected. By reviewing all your medicines, your prescriber can choose the safest starting dose and give you tailored advice.

What you need to know

• No major interaction is reported between vardenafil and ipratropium—they work in different parts of the body.
• Always declare all medicines, including inhalers, during your ED consultation for a full safety review.
• Never take vardenafil with nitrates, nicorandil, riociguat, or poppers—this can cause dangerous low blood pressure.
• Vardenafil is taken 25–60 minutes before sex and only works with sexual stimulation.
• Cured Pharmacy offers ED treatments from £0.45 after a UK prescriber consultation.

What your prescriber checks before prescribing vardenafil

When you request vardenafil (or any PDE5 inhibitor) through an online consultation at Cured Pharmacy, a UK-registered prescriber will review your answers to a detailed health questionnaire. This assessment is a legal and clinical requirement to ensure the medicine is safe for you [2].

Your prescriber will check for conditions that make PDE5 inhibitors unsuitable, such as recent heart attack or stroke, unstable angina, severe heart failure, very low blood pressure, or a history of sudden vision loss (non-arteritic anterior ischaemic optic neuropathy, or NAION) [5]. They will also review all your current medicines to identify any that could interact dangerously with vardenafil. Medicines you must never take with vardenafil include nitrates (such as GTN spray or isosorbide mononitrate), nicorandil, riociguat, and recreational drugs called 'poppers' (amyl or alkyl nitrites), because the combination can cause a dangerous drop in blood pressure [5].

Your prescriber will also check for medicines that require dose adjustments, such as potent CYP3A4 inhibitors (including some HIV medicines like ritonavir, antifungals like ketoconazole, or antibiotics like clarithromycin), which can raise vardenafil levels in your blood. With potent inhibitors, vardenafil is often avoided or contraindicated [5]. Alpha-blockers for prostate problems (such as tamsulosin or doxazosin) can also interact, so your prescriber will ensure you are stable on the alpha-blocker and may start you on a lower dose of vardenafil.

Declaring your inhaler and other medicines

When you complete your online consultation, you will be asked to list all your current medicines, including prescription medicines, over-the-counter treatments, inhalers, eye drops, creams, and any herbal or vitamin supplements. It is important to include your ipratropium inhaler (and any other inhalers you use) in this list, even though it is unlikely to interact with vardenafil. This allows your prescriber to see your full respiratory and cardiovascular health, which can be relevant when assessing whether sexual activity and ED treatment are safe for you. Never stop or change a prescribed medicine without advice from your doctor or pharmacist.

Vardenafil and ipratropium: practical advice for safe use

If you have been prescribed vardenafil and you use ipratropium for a lung condition, you can usually take both medicines as directed without concern. Use your ipratropium inhaler exactly as your doctor or respiratory specialist has instructed—typically this means regular doses throughout the day, or as needed for breathlessness. Take vardenafil about 25 to 60 minutes before you plan to have sex, and remember that it will only work if you are sexually aroused [5].

There is no need to time your inhaler doses around your vardenafil tablet, because the two medicines do not interact in a way that requires separation. However, if you use other inhalers or tablets for your lungs or heart (such as beta-blockers, calcium-channel blockers, or corticosteroids), make sure your prescriber knows about them, as some of these can have interactions or require monitoring.

If you experience any unusual symptoms after starting vardenafil—such as severe dizziness, chest pain during sex, sudden vision or hearing loss, or an erection lasting more than four hours—stop taking the medicine and seek urgent medical help [5]. These are rare but serious side effects that require immediate attention. If your breathing worsens or your inhaler becomes less effective, contact your GP or respiratory team, as this may be unrelated to vardenafil but still needs investigation.

When to get urgent help

• Erection lasting more than 4 hours (priapism)—go to A&E immediately
• Sudden loss of vision or hearing—stop vardenafil and seek urgent medical help
• Chest pain during or after sex—call 999 and do not take another dose
• Severe dizziness or fainting after taking vardenafil—seek same-day medical advice
• Sudden worsening of breathlessness unrelated to your usual lung condition—contact your GP or call 111

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

Other ED treatments available at Cured Pharmacy

Cured Pharmacy offers a range of licensed ED treatments, all available after an online consultation reviewed by a UK prescriber. If vardenafil is not suitable for you, or if you would like to try a different PDE5 inhibitor, alternatives include sildenafil (generic Viagra), which is taken about one hour before sex and is available from £0.45 per tablet (£0.36 with first-order code Ednew); tadalafil (generic Cialis), which can be taken on-demand or daily and lasts up to 36 hours, from £7.95 (£6.36 with code Ednew); and avanafil (Spedra), which works in as little as 15 to 30 minutes, priced at £20.95 (£16.76 with code Ednew) [2][6].

All PDE5 inhibitors work in a similar way and have similar interactions and precautions, so the same advice about declaring all your medicines (including ipratropium) applies whichever treatment you choose. Your prescriber will help you select the most suitable option based on your lifestyle, how quickly you want the medicine to work, and any other health conditions or medicines you have.

If you have not yet seen a GP about your erectile dysfunction, it is a good idea to do so. ED can be an early warning sign of heart disease, diabetes, or other health problems, and your GP can arrange tests and address any underlying causes [1][2]. Treating ED with medicine can be very effective, but it works best alongside a healthy lifestyle—stopping smoking, reducing alcohol, staying active, and managing stress can all improve your erections and overall health.
