What is Tadalafil and How Does It Work?

Tadalafil is a prescription medicine used to treat erectile dysfunction (ED) in men. It belongs to a group of medicines called PDE5 inhibitors, which work by relaxing blood vessels in the penis, allowing more blood to flow in when you are sexually aroused [4].

Tadalafil is available in two forms: on-demand tablets (10mg or 20mg) taken at least 30 minutes before sexual activity, with effects lasting up to 36 hours, and daily tablets (2.5mg or 5mg) taken once a day at the same time. Unlike some other ED treatments, tadalafil's long duration means you don't need to time it as precisely around sex [4].

Tadalafil only works when you are sexually stimulated—it does not cause an automatic erection. At Cured Pharmacy, tadalafil is available after an online consultation reviewed by a UK prescriber, with generic Tadalafil starting from £7.95 and branded Cialis from £12.00.

What is Ibuprofen and When is It Used?

Ibuprofen is a widely used over-the-counter painkiller and anti-inflammatory medicine. It belongs to a class of drugs called non-steroidal anti-inflammatory drugs (NSAIDs) and is commonly taken for headaches, muscle pain, dental pain, period pain, fever, and conditions like arthritis.

Ibuprofen works by blocking the production of chemicals in the body called prostaglandins, which cause pain, inflammation, and fever. It is available in various strengths (typically 200mg to 400mg per tablet) and can be bought without a prescription from pharmacies and supermarkets.

While ibuprofen is generally safe for short-term use in most people, it can cause side effects, particularly stomach irritation, and is not suitable for everyone. People with a history of stomach ulcers, severe heart failure, or kidney problems should avoid it or use it only under medical supervision.

Can You Take Tadalafil and Ibuprofen Together?

Yes, tadalafil and ibuprofen can generally be taken together. There is no major direct drug interaction between these two medicines that would make the combination unsafe for most people. Many men take ibuprofen for everyday aches and pains while also using tadalafil for erectile dysfunction without problems.

However, both medicines can have an effect on blood pressure. Tadalafil causes a mild lowering of blood pressure as part of how it works (by relaxing blood vessels), and ibuprofen, particularly when used regularly or at high doses, can sometimes raise blood pressure or interfere with blood pressure medicines [4].

This means that while the combination is not contraindicated, your prescriber will want to know if you take ibuprofen or other NSAIDs regularly, especially if you also have high blood pressure or take blood pressure medicines. Occasional use of ibuprofen for a headache or minor pain is unlikely to cause problems, but it's always best to mention all medicines—including over-the-counter ones—during your consultation.

How the Combination Affects Blood Pressure

Tadalafil lowers blood pressure slightly by widening blood vessels throughout the body, not just in the penis. This effect is usually mild and well-tolerated, but it can add to the blood-pressure-lowering effect of other medicines [4].

Ibuprofen, on the other hand, can raise blood pressure in some people, particularly with long-term use or high doses. It can also reduce the effectiveness of some blood pressure medicines. If you take both tadalafil and ibuprofen, these opposing effects may partially cancel each other out, but the interaction is unpredictable and depends on individual factors such as your overall health, other medicines, and the doses used.

What Your Prescriber Checks Before Approving Tadalafil

When you request tadalafil through Cured Pharmacy's online consultation, a UK-registered prescriber reviews your medical history and current medicines to ensure it is safe for you. They will ask about all medicines you take, including over-the-counter painkillers like ibuprofen, herbal supplements, and recreational drugs.

Your prescriber will check for conditions that make tadalafil unsuitable, such as recent heart attack or stroke, unstable angina, severe heart failure, very low blood pressure, or previous sudden vision loss (NAION). They will also check whether you take any medicines that must never be combined with tadalafil, including nitrates (GTN spray, isosorbide), nicorandil, riociguat, or poppers (amyl/alkyl nitrites) [4].

If you take blood pressure medicines, including alpha-blockers like tamsulosin or doxazosin, your prescriber will ensure you are stable on that treatment and may start you on a lower dose of tadalafil. Regular use of NSAIDs like ibuprofen will be noted, particularly if you have cardiovascular conditions, but it does not automatically prevent you from using tadalafil safely.

Practical Advice for Taking Tadalafil and Ibuprofen

If you occasionally take ibuprofen for a headache, muscle pain, or other minor ailments, you can generally continue to do so while using tadalafil. There is no need to avoid ibuprofen completely or to space the doses apart in a specific way, as there is no direct interaction that requires timing adjustments.

However, if you take ibuprofen regularly (for example, for arthritis or chronic pain), make sure your prescriber knows this during your consultation. They may want to monitor your blood pressure or adjust your treatment plan. Avoid taking more ibuprofen than recommended on the packet, and do not use it for prolonged periods without medical advice.

Be aware of the side effects of both medicines. Tadalafil can cause headache, indigestion, back pain, muscle aches, flushing, and nasal congestion. Ibuprofen can cause stomach upset, indigestion, and, with long-term use, an increased risk of stomach ulcers and cardiovascular problems. If you experience dizziness, light-headedness, or a significant drop in blood pressure when standing up, contact your GP or pharmacist for advice.

When to Seek Medical Advice

Seek urgent medical help if you experience an erection lasting more than four hours (priapism), sudden loss of vision or hearing, or chest pain during sexual activity while taking tadalafil. These are rare but serious side effects that require immediate attention [4].

If you develop severe stomach pain, black or bloody stools, or vomit that looks like coffee grounds while taking ibuprofen, stop the medicine and seek medical help immediately, as these can be signs of a stomach ulcer or bleeding. Always read the patient information leaflet that comes with your medicines and contact your GP or pharmacist if you have any concerns.

Other Medicines and Interactions with Tadalafil

While tadalafil and ibuprofen can be taken together, there are some medicines that must never be combined with tadalafil. Do not take tadalafil if you use nitrates (such as GTN spray, isosorbide mononitrate, or isosorbide dinitrate) for angina, nicorandil for chest pain, riociguat for pulmonary hypertension, or recreational drugs called poppers (amyl or alkyl nitrites). The combination can cause a dangerous drop in blood pressure [4].

Other medicines can affect how tadalafil works or increase the risk of side effects. Alpha-blockers (such as tamsulosin, doxazosin, or alfuzosin) used for prostate problems can add to the blood-pressure-lowering effect of tadalafil, so your prescriber will ensure you are stable on the alpha-blocker and may start you on a lower dose of tadalafil. Potent CYP3A4 inhibitors (such as ritonavir, ketoconazole, itraconazole, or clarithromycin) can raise tadalafil levels in the blood, requiring dose adjustments [4].

Other blood pressure medicines, including ACE inhibitors, calcium channel blockers, and diuretics, can also add to the blood-pressure-lowering effect of tadalafil. This is usually manageable, but you must declare all medicines during your consultation. Grapefruit juice can raise tadalafil levels and should be avoided, and heavy alcohol can worsen erectile dysfunction and increase the risk of side effects such as dizziness and low blood pressure [4].

What About Other Painkillers?

Paracetamol, another common over-the-counter painkiller, has no known interaction with tadalafil and is generally considered safe to take together. If you need pain relief while using tadalafil, paracetamol may be a suitable alternative to ibuprofen, particularly if you have concerns about blood pressure or stomach problems.

Aspirin, often taken in low doses to prevent heart attacks and strokes, can be taken with tadalafil, but your prescriber will want to know about it during your consultation. Other NSAIDs, such as naproxen or diclofenac, have similar considerations to ibuprofen and should also be declared. Never take more than one NSAID at a time unless specifically advised by a doctor.

When to get urgent help

• Erection lasting more than 4 hours (priapism) – go to A&E immediately
• Sudden loss of vision or hearing – stop tadalafil and seek urgent medical help
• Chest pain during sexual activity – stop and call 999 if it does not resolve quickly
• Severe stomach pain, black stools, or vomiting blood while taking ibuprofen – seek immediate medical attention
• Severe dizziness or fainting after taking tadalafil – lie down and contact your GP or call 111

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