Statins are generally safe and well-tolerated. However, like all medicines, they can interact with certain foods, drinks, and other medications. Knowing what to avoid, and what’s fine to continue with, can help you get the most from your treatment and reduce the risk of statins side effects.
Our guide covers the relationship between statins and alcohol, what medications to be aware of, and foods to avoid while on your treatment.
Three key takeaways
Drinking alcohol in moderation is generally fine on statins, but heavy or regular drinking increases the risk of liver problems.
Several medicines, including certain antibiotics and antifungals, can interact with statins and should be flagged to your general practitioner or pharmacist.
Statins and alcohol: do they mix?
Yes, you can drink alcohol in moderation while taking statins. However, drinking heavily or regularly can increase the risk of liver problems. Since statins can also affect the liver in rare cases, combining the two in excess is not recommended.
The NHS advises keeping within the recommended guidelines of no more than 14 units of alcohol per week, spread across several days. If you regularly drink more than this, let your GP know before starting statin treatment.
"Most people on statins can enjoy an occasional drink without any issue. The concern is with heavy, regular alcohol use. Both statins and alcohol are metabolised by the liver, so excessive alcohol intake while taking statins may increase the strain on your liver and raise your risk of liver toxicity. If you're unsure what's safe for you, it's always worth a quick conversation with your doctor or pharmacist."
All this said, it’s important to watch for signs of liver problems. Seek medical advice if you notice any of the following while taking statins and drinking alcohol:
Several medicines can interact with statins, either increasing the amount of statin in your blood (raising the risk of side effects) or reducing how well the statin works. Always tell your GP and pharmacist about every medicine you are taking, including supplements and herbal remedies, before starting or changing your statin.
Antibiotics and statins
Antibiotics are one of the most common medications that can interact with statins. For example, clarithromycin and erythromycin can significantly increase statin levels in the blood, raising the risk of muscle problems.
According to NHS Specialist Pharmacy Service guidance, these antibiotics should ideally be avoided with atorvastatin, and simvastatin must be stopped during a course of clarithromycin. Azithromycin is generally considered safer.
Other medications and statins
Additional medications that can interact with statins include:
Antifungal medicines: Itraconazole and other azole antifungals can increase statin concentrations.
HIV medications: Certain antiretrovirals interact with statins metabolised by the liver enzyme CYP3A4.
Ciclosporin: Used after organ transplants and can significantly raise statin levels.
Warfarin and other anticoagulants: Statins can enhance the blood-thinning effect of warfarin, so your INR may need closer monitoring.
Niacin (high-dose vitamin B3): Can increase the risk of muscle problems when taken alongside statins.
St John's wort: This herbal supplement can reduce the effectiveness of some statins, including atorvastatin and simvastatin, by speeding up how they are broken down.
If you are prescribed a new medicine, always check with your pharmacist whether it is safe to take alongside your statin. They can advise whether a dose adjustment or temporary stop is needed.
Do statins interact with clopidogrel?
Clopidogrel is an antiplatelet medication that can help prevent heart attacks, strokes, and serious blood clots in patients with acute coronary syndrome (ACS). It’s often known by the brand name Plavix.
Atorvastatin and clopidogrel are frequently prescribed together, particularly for people who have had a heart attack or who have coronary artery disease. In most clinical situations, this combination is considered safe and is standard practice. If you have concerns about taking both medicines, speak to your GP before making any changes.
Foods to avoid on statins
Statins don't come with a long list of dietary restrictions, but there are a couple of things worth knowing about before you eat or drink them alongside your medication.
Grapefruit and grapefruit juice
Grapefruit is the most significant food interaction when it comes to statins. It contains natural compounds called furanocoumarins, which block an enzyme in your gut (CYP3A4) that helps break down certain statins. When this enzyme is blocked, more of the statin enters your bloodstream than intended. This can increase the risk of side effects, including muscle pain and, in rare cases, more serious muscle damage.
Statins affected by grapefruit include:
Atorvastatin: A small occasional glass is generally considered safe, but large quantities (more than 1.2 litres daily) should be avoided.
Simvastatin: Avoid grapefruit and grapefruit juice entirely.
Lovastatin: Avoid grapefruit entirely.
Statins not significantly affected by grapefruit:
rosuvastatin
pravastatin
fluvastatin
If you regularly eat grapefruit and are being prescribed a statin, mention this to your GP. It may influence which statin is most suitable for you.
High-fat and high-cholesterol foods
While not a direct drug interaction, regularly eating foods high in saturated fat works against what statins are trying to achieve. Statins lower the cholesterol your liver produces, but a diet high in saturated fat keeps adding dietary cholesterol to your bloodstream.
Foods to limit include:
fatty meats and processed meats such as bacon, sausages, and pies
full-fat dairy products such as butter, cream, and hard cheese
foods containing palm oil or coconut oil
pastries, cakes, and biscuits made with butter or lard

Frequently asked questions about statins interactions
Can you take atorvastatin and paracetamol?
Yes, paracetamol is generally safe to take alongside atorvastatin. There is no clinically significant interaction between the two. However, as both medicines are processed by the liver, you should stick to the recommended dose of paracetamol of no more than 4,000 mg per day. You should also avoid taking it alongside heavy alcohol use.
Can I drink milk with atorvastatin?
Yes, you can drink milk as it does not interact with atorvastatin. You can take atorvastatin with or without food and with any non-grapefruit drink, including milk, water, or tea. There is no need to avoid dairy products while taking statins.
Is it okay to eat bananas while taking atorvastatin?
Yes, bananas are fine to eat on atorvastatin. They do not interact with statins in any clinically meaningful way. A heart-healthy diet that includes fruit such as bananas is actively encouraged alongside statin treatment. The only fruit you need to be cautious about is grapefruit.
