What Is Vardenafil?

Vardenafil is a prescription medicine used to treat erectile dysfunction (ED) in adult men [1]. 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 are sexually aroused [5]. Vardenafil is the generic version of the branded medicine Levitra.

Vardenafil is available in 5mg, 10mg and 20mg tablets. You typically take it about 25 to 60 minutes before sexual activity, and it can remain effective for several hours [5]. Like all PDE5 inhibitors, vardenafil requires sexual stimulation to work—it will not cause an erection on its own.

Common side effects include headache, flushing, indigestion and nasal congestion [5]. Vardenafil is not suitable for everyone, particularly men taking nitrates for angina, those with severe heart or liver problems, or anyone who has experienced sudden vision loss. Your prescriber will assess your suitability during an online consultation before issuing a prescription.

What Is Meloxicam?

Meloxicam is a non-steroidal anti-inflammatory drug (NSAID) prescribed to relieve pain and inflammation in conditions such as osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. It works by blocking enzymes (COX-1 and COX-2) that produce prostaglandins, chemicals in the body that cause pain, swelling and inflammation.

Meloxicam is usually taken once daily as a 7.5mg or 15mg tablet, often with or after food to reduce the risk of stomach upset. Like other NSAIDs, meloxicam can increase the risk of stomach ulcers, bleeding, heart attack and stroke, particularly when used at high doses or for long periods.

NSAIDs can also affect kidney function and may raise blood pressure in some people. Your GP or prescriber will consider your cardiovascular and kidney health, as well as any other medicines you take, before prescribing meloxicam. If you have a history of heart disease, high blood pressure, kidney problems or stomach ulcers, meloxicam may not be suitable or may require careful monitoring.

How Do Vardenafil and Meloxicam Interact?

There is no major direct drug interaction between vardenafil and meloxicam that would prevent you from taking them together. Neither medicine significantly affects the metabolism or blood levels of the other, so they do not interfere with each other's effectiveness in the way that, for example, certain antibiotics or antifungals can.

However, both medicines can have effects on your cardiovascular system. Vardenafil lowers blood pressure slightly as part of its mechanism of action [5]. Meloxicam and other NSAIDs can sometimes raise blood pressure or reduce the effectiveness of blood-pressure-lowering medicines, and they may also cause fluid retention in some people.

For most men, this combination is manageable, but your prescriber will check your blood pressure, heart health and kidney function during your consultation. If you have existing high blood pressure, heart disease or kidney problems, your prescriber may adjust doses, recommend monitoring or suggest an alternative treatment. It is important to declare all your current medicines and health conditions so that your prescriber can make a safe, informed decision.

What Your Prescriber Will Check

During your online consultation, your prescriber will ask about your cardiovascular health, including any history of high blood pressure, heart attack, stroke, angina or heart failure. They will also ask about kidney function, as both vardenafil and meloxicam can affect the kidneys, particularly in people with pre-existing kidney disease or those taking other medicines that affect kidney function (such as ACE inhibitors or diuretics).

Your prescriber will review all your current medicines to check for interactions. If you are taking other blood-pressure medicines, your prescriber will ensure that adding vardenafil will not cause your blood pressure to drop too low, leading to dizziness or fainting. They will also consider whether meloxicam is being used short-term (for example, for acute pain) or long-term, as the risks differ.

Practical Advice for Taking Vardenafil and Meloxicam Together

If your prescriber confirms that the combination is suitable for you, there are some practical steps you can take to use both medicines safely. Take each medicine exactly as prescribed, at the dose and frequency your prescriber recommends. Do not take more vardenafil than prescribed, and do not exceed the maximum daily dose of meloxicam.

Monitor for any new or unusual symptoms, particularly dizziness, light-headedness, swelling in your ankles or feet, or changes in urination (which could indicate kidney problems). If you experience chest pain during sexual activity, stop and seek urgent medical help—do not assume it is a side effect of the medicines.

Stay well hydrated, especially if you are taking meloxicam, as dehydration can increase the risk of kidney problems with NSAIDs. Limit alcohol, as heavy drinking can worsen erectile dysfunction, increase the risk of side effects from both medicines, and add to the blood-pressure-lowering effect of vardenafil. If you develop any side effects or have concerns, contact your GP or pharmacist for advice rather than stopping your medicines suddenly.

Other Medicines and Vardenafil: What You Need to Know

While vardenafil and meloxicam can usually be taken together, there are some medicines that must never be combined with vardenafil. Do 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). The combination can cause a dangerous, potentially life-threatening drop in blood pressure [5].

If you take alpha-blockers for an enlarged prostate (such as tamsulosin, doxazosin or alfuzosin), you may be at increased risk of dizziness or low blood pressure when starting vardenafil. Your prescriber will ensure you are stable on the alpha-blocker and will usually start you on the lowest dose of vardenafil [5].

Certain medicines that affect liver enzymes—particularly potent CYP3A4 inhibitors such as ritonavir, cobicistat, ketoconazole, itraconazole and clarithromycin—can raise vardenafil levels in the blood, increasing the risk of side effects. Vardenafil is often avoided or contraindicated with these medicines; your prescriber will check the summary of product characteristics if you are taking any of these drugs [5]. Always declare every medicine, supplement and herbal remedy you take during your consultation.

Medicines That Lower Blood Pressure

If you take other blood-pressure-lowering medicines (such as amlodipine, ramipril, bisoprolol or losartan), adding vardenafil may cause an additional drop in blood pressure. For most men, this is manageable and does not cause problems, but some people may experience dizziness, light-headedness or fainting, particularly when standing up quickly.

Your prescriber will review your blood pressure control and may recommend starting on a lower dose of vardenafil or monitoring your blood pressure at home. If you feel dizzy or faint after taking vardenafil, sit or lie down until the symptoms pass, and contact your GP or pharmacist for advice.

When to Seek Medical Help

Most men taking vardenafil and meloxicam together will not experience serious problems, but it is important to know the warning signs that require urgent medical attention. If you develop an erection that lasts longer than four hours (priapism), seek emergency help immediately, as this can cause permanent damage to the penis if not treated promptly [5].

Sudden loss of vision in one or both eyes, or sudden decrease or loss of hearing (sometimes with ringing in the ears or dizziness), are rare but serious side effects of PDE5 inhibitors. Stop taking vardenafil and seek urgent medical help if this happens [5]. If you experience chest pain during or after sexual activity, stop and call 999—do not take more vardenafil or use GTN spray if you have taken vardenafil within the last 24 hours.

Signs of a serious allergic reaction (such as swelling of the face, lips, tongue or throat, difficulty breathing, or a severe skin rash) require immediate emergency help. If you develop severe stomach pain, black or bloody stools, or vomit that looks like coffee grounds while taking meloxicam, contact your GP urgently or go to A&E, as these may be signs of a stomach ulcer or bleeding. Always read the patient information leaflet that comes with your medicine and report any side effects to your prescriber or pharmacist.

Reporting Side Effects

If you experience any side effects while taking vardenafil or meloxicam, talk to your doctor or pharmacist. You can also report side effects directly via the UK Yellow Card Scheme at www.mhra.gov.uk/yellowcard or by searching for 'Yellow Card' in the Google Play or Apple App Store. Reporting side effects helps improve the safety information available about medicines.

When to get urgent help

• Erection lasting longer 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; do not use GTN if you have taken vardenafil
• Severe stomach pain, black stools or vomiting blood while taking meloxicam—contact GP urgently or go to A&E
• Swelling of face, lips or throat, or difficulty breathing—call 999 for allergic reaction

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