What is tadalafil and rosuvastatin used for?

Tadalafil is a prescription medicine used to treat erectile dysfunction (ED) in 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 [3][4]. Tadalafil is available as on-demand tablets (10mg or 20mg, taken at least 30 minutes before sex, with effects lasting up to 36 hours) or as a daily low-dose tablet (2.5mg or 5mg) [4].

Rosuvastatin is a statin medicine prescribed to lower cholesterol levels in the blood [12]. High cholesterol increases your risk of heart disease and stroke, so rosuvastatin helps protect your cardiovascular system by reducing the amount of 'bad' LDL cholesterol your body produces. Many men with ED also have high cholesterol, as both conditions share common risk factors such as age, diabetes, high blood pressure, and smoking [1][10].

Because cardiovascular health and erectile function are closely linked, it is not unusual for men to be prescribed both medicines. Erectile dysfunction can sometimes be an early warning sign of heart disease, which is why it is important to see your GP if you develop new ED symptoms [1][2].

How do tadalafil and rosuvastatin interact?

Tadalafil and rosuvastatin do not have a significant direct interaction that would prevent you from taking them together. Rosuvastatin is not a potent inhibitor of the liver enzymes (CYP3A4) that break down tadalafil, so it does not significantly raise tadalafil levels in your bloodstream [4][12].

However, both medicines can have effects on your cardiovascular system. Tadalafil can cause a small drop in blood pressure, and while rosuvastatin itself does not lower blood pressure, some people taking statins may experience muscle-related side effects or, very rarely, effects on liver function [12]. Your prescriber will review your full medication list and medical history to ensure that the combination is safe for you, particularly if you are also taking other blood-pressure medicines or have underlying heart conditions [2][4].

It is also worth noting that tadalafil is broken down by an enzyme called CYP3A4. Medicines that strongly inhibit this enzyme (such as ritonavir, ketoconazole, or clarithromycin) can raise tadalafil levels and require dose adjustments, but rosuvastatin is not one of these medicines [4]. Your prescriber will check for any other medicines you are taking that might interact with tadalafil during your consultation.

What your prescriber checks

During your online consultation at Cured Pharmacy, the prescriber will review your current medicines, including rosuvastatin, and check for any contraindications or interactions. They will ask about your cardiovascular health, blood pressure, any history of heart attack or stroke, and whether you are taking any medicines that must not be combined with tadalafil, such as nitrates (GTN spray, isosorbide mononitrate), nicorandil, riociguat, or 'poppers' (amyl/alkyl nitrites) [2][4]. These combinations can cause a dangerous drop in blood pressure and must be avoided.

Are there any risks when taking tadalafil with rosuvastatin?

For most men, taking tadalafil and rosuvastatin together is well tolerated and does not cause additional problems. However, as with any medicine, there are some general considerations to keep in mind.

Tadalafil can cause side effects such as headache, indigestion, back pain, muscle aches, flushing, or a stuffy nose [4]. Rosuvastatin can occasionally cause muscle aches or pains, and very rarely more serious muscle problems [12]. If you experience unexplained muscle pain, tenderness, or weakness while taking both medicines, contact your GP, as this may need further investigation.

Tadalafil can also cause a small drop in blood pressure, which may lead to dizziness, particularly when standing up quickly [4]. If you are taking other medicines that lower blood pressure (such as alpha-blockers like tamsulosin or doxazosin, or other blood-pressure tablets), your prescriber will need to ensure you are stable on those medicines and may start you on a lower dose of tadalafil [2][4].

Sexual activity itself puts extra strain on your heart, so tadalafil is not suitable if your doctor has advised you to avoid sexual activity due to severe heart problems, recent heart attack or stroke, unstable angina, or very low blood pressure [2][4]. Your prescriber will assess your cardiovascular fitness during the consultation.

What you need to know

• Tadalafil and rosuvastatin can usually be taken together safely with no major interaction reported
• Your prescriber will review your full medical history and current medicines during consultation
• Never take tadalafil with nitrates, nicorandil, riociguat, poppers, or another PDE5 inhibitor
• Report unexplained muscle pain or new symptoms to your GP or pharmacist
• Tadalafil requires a prescription and is available through a UK pharmacist-led online consultation

Practical advice for taking tadalafil and rosuvastatin together

If your prescriber approves tadalafil for you, take it exactly as directed. On-demand tadalafil (10mg or 20mg) should be taken at least 30 minutes before sexual activity, and the effect can last up to 36 hours [4]. Daily tadalafil (2.5mg or 5mg) is taken once a day at the same time, regardless of when you plan to have sex. Tadalafil requires sexual stimulation to work; it will not cause an automatic erection [4].

Continue taking your rosuvastatin as prescribed by your GP. Statins are usually taken once daily, often in the evening, and should not be stopped without medical advice [12]. If you experience any new or worsening symptoms after starting tadalafil, such as chest pain during sex, dizziness, or unexplained muscle pain, stop taking tadalafil and contact your GP or pharmacist.

Avoid drinking large amounts of alcohol when taking tadalafil, as alcohol can make erectile dysfunction worse and add to the blood-pressure-lowering effect, increasing the risk of dizziness [4]. Grapefruit juice can raise the levels of tadalafil in your blood, so it is best to avoid it or limit your intake [4].

Always tell your prescriber and pharmacist about all the medicines you are taking, including over-the-counter medicines, herbal remedies (such as St John's wort), and supplements. Never take tadalafil with nitrates, nicorandil, riociguat, poppers, or another PDE5 inhibitor, as these combinations are dangerous [2][4].

When to seek urgent help

Seek urgent medical help (call 999 or go to A&E) if you experience chest pain or discomfort during or after sex, as this may be a sign of a heart problem [2][4]. Also seek immediate help if you have an erection lasting more than four hours (priapism), as this can cause permanent damage if not treated promptly [4]. Sudden loss of vision or hearing is rare but requires urgent assessment [4].

Other medicines and conditions to consider with tadalafil

While tadalafil and rosuvastatin can usually be taken together, there are other medicines and health conditions that may affect whether tadalafil is suitable for you. Your prescriber will check for these during your consultation [2][4].

Tadalafil must never be taken with nitrates (such as GTN spray, isosorbide mononitrate, or isosorbide dinitrate), nicorandil, riociguat, or recreational drugs known as 'poppers' (amyl or alkyl nitrites). These combinations can cause a severe and potentially life-threatening drop in blood pressure [2][4]. Do not take tadalafil together with another PDE5 inhibitor (such as sildenafil, vardenafil, or avanafil) [4].

If you are taking alpha-blockers for an enlarged prostate (such as tamsulosin, doxazosin, alfuzosin, or terazosin), you should be stable on the alpha-blocker before starting tadalafil, and your prescriber may recommend a lower starting dose to reduce the risk of dizziness or low blood pressure [2][4].

Certain medicines that strongly inhibit the liver enzyme CYP3A4 (such as ritonavir, cobicistat, ketoconazole, itraconazole, or clarithromycin) can raise tadalafil levels, requiring dose adjustments or avoidance [4]. Medicines that induce CYP3A4 (such as rifampicin, carbamazepine, phenytoin, or St John's wort) can reduce the effectiveness of tadalafil [4]. Your prescriber will review all your current medicines to check for these interactions.

When to get urgent help

• Chest pain or discomfort during or after sex – call 999 immediately
• Erection lasting more than 4 hours (priapism) – go to A&E straight away
• Sudden loss of vision or hearing – seek urgent medical attention
• Severe dizziness, fainting, or very low blood pressure – call 999 or go to A&E
• Unexplained severe muscle pain, tenderness, or weakness – contact your GP the same day

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