What is atorvastatin used for?

Atorvastatin is used to lower cholesterol and reduce the risk of cardiovascular disease. In turn, this may reduce your risk for heart attack and stroke.

It’s prescribed to adults and some children when lifestyle changes haven’t been able to bring cholesterol under control, or if you are at higher risk of developing cardiovascular disease.

It’s commonly prescribed for people who:

• have high cholesterol (hypercholesterolaemia)
• have a high risk of cardiovascular disease
• are living with diabetes
• have a family history of heart disease
• have had a cardiovascular event like a heart attack or stroke

What is in atorvastatin?

The active ingredient is atorvastatin calcium, which belongs to a group of medicines called statins. Each tablet also contains inactive ingredients to help bind and coat the tablet. These ingredients include:

• calcium carbonate
• microcrystalline cellulose
• lactose monohydrate

For a full list of ingredients, refer to the patient information leaflet (PIL) included with your medication.

Is atorvastatin the same as Lipitor?

Yes, atorvastatin is the generic version of Lipitor. Both contain the same active ingredient and work in exactly the same way.

Lipitor is simply the brand name used by Pfizer, while atorvastatin is the generic name used once the patent expired. Generic atorvastatin is equally effective and is the version most commonly prescribed on the NHS.

How do statins work?

Atorvastatin works by blocking an enzyme in your liver called HMG-CoA reductase. Your body uses this enzyme to produce cholesterol. By reducing how much cholesterol your liver makes, atorvastatin lowers the overall level of LDL (usually labelled ‘bad’) cholesterol in your blood.

Lower LDL cholesterol means less build-up of fatty deposits in your arteries. This can reduce the risk of blockages that lead to heart attacks and strokes.

How long do statins take to work?

Atorvastatin can lower your cholesterol levels within four weeks. Your doctor may recommend getting a blood test after around three months to check your cholesterol level. This can help assess how well the medication is working.

How effective is atorvastatin?

Atorvastatin, like many statins, is highly effective at reducing cholesterol. One study found that 40mg atorvastatin reduced patients’ cholesterol by an average of 49%. Higher doses of atorvastatin (40mg or 80mg) are typically used for people at higher cardiovascular risk.

Atorvastatin dosages

Atorvastatin is available in four doses ranging from 10mg to 80mg. The right dose for you depends on your cholesterol levels, cardiovascular risk, and how well you respond to the medication.

Practitioners often follow these general guidelines:

• 10mg and 20mg. This is typically starting doses or for people at lower risk.
• 40mg. This dose is often prescribed for cardiovascular prevention.
• 80mg. This is a high dose used for people with significant cardiovascular risk or established disease. It may also be used for those with very high cholesterol.

Never change your dose without speaking to your GP or pharmacist first.

What happens if you miss a dose of atorvastatin?

If you miss a dose, take it as soon as you remember unless it’s almost time for your next dose. In that case, skip the missed dose and continue as normal.

 Do not take a double dose to make up for a missed one.

How to take atorvastatin

Swallow atorvastatin tablets whole with a glass of water. You can take atorvastatin with or without food. Take it at the same time each day to help you build up a consistent routine.

When is the best time of day to take atorvastatin?

Unlike some other statins, atorvastatin can be taken at any time of day. However, many people find it easier to take it in the evening with their last meal or before bed simply as a routine. Consistency matters more than timing.

Atorvastatin side effects

Like all medicines, atorvastatin can cause side effects in some people, though not everyone will experience them. It’s worth noting that clinical evidence suggests many side effects listed in product labels may be less common than previously thought.

Common side effects include:

• muscle aches or weakness
• nausea or digestive upset
• headaches
• joint pain

Atorvastatin can cause a rare but serious condition called rhabdomyolysis. Seek urgent medical help if you experience the following (especially if accompanied by a fever or dark urine):

• severe, unexplained muscle pain
• weakness
• tenderness

Are statins safe?

Yes, statins are considered safe for most people and have been extensively studied. The benefits of taking atorvastatin to reduce the risk of heart attack or stroke generally outweigh the risks of side effects for most patients.

If you are concerned about side effects, speak to your healthcare practitioner or pharmacist before stopping your medication.

Pros and cons of statins

Pros:

• Significantly reduces the risk of heart attack and stroke.
• Well-studied with decades of clinical evidence.
• Once-daily dosing makes it straightforward to take.
• Available on the NHS at low or no cost.

Cons:

• Some people experience muscle aches or digestive side effects.
• Needs to be taken long-term to maintain benefits.
• Not suitable during pregnancy or breastfeeding.
• Can interact with certain medicines and foods (including grapefruit juice).

When to avoid atorvastatin

Atorvastatin isn’t suitable for everyone. Do not take it if you have:

• liver disease
• ever had an allergic reaction to atorvastatin
• ever had an allergic reaction to other statins

Atorvastatin and other medications

Atorvastatin can interact with several medicines, which may affect how it works or increase the risk of side effects. Always tell your GP or pharmacist about all medicines you are taking, including supplements.

Medicines that can interact with atorvastatin include (but are not limited to):

• certain antibiotics (like clarithromycin or erythromycin)
• antifungal medicines (like itraconazole)
• HIV medications
• ciclosporin
• warfarin and other blood-thinning medicines

Atorvastatin and alcohol

You can drink alcohol while taking atorvastatin. However, you should stick within the recommended UK guidelines of no more than 14 units per week. Drinking excessively can increase your risk of liver problems, which atorvastatin can also affect in rare cases.

Atorvastatin and pregnancy, breastfeeding, and fertility

Do not take atorvastatin if you are pregnant, trying to conceive, or breastfeeding. It may harm an unborn baby. If you become pregnant while taking atorvastatin, stop taking it immediately and speak to your GP.

How to store atorvastatin

Store atorvastatin tablets at room temperature, between 20-25°C. Keep them in their original packaging and away from direct sunlight and moisture.

Keep all medications outside of the reach of children.

Alternatives to atorvastatin

If atorvastatin is not suitable for you, your GP may consider other statins or cholesterol-lowering options. Other statins available on the NHS include:

• fluvastatin
• pravastatin
• rosuvastatin
• simvastatin

Lifestyle changes can also help lower cholesterol alongside or instead of medication, including:

• eating a diet lower in saturated fat and higher in fibre
• stopping smoking
• exercising regularly, ideally at least 150 minutes of moderate activity per week
• reducing your alcohol intake
• maintaining a healthy weight

There are also other cholesterol lowering medications available if you have tried a few statins and they don’t seem to suit you. Speak to your GP about alternatives.

Frequently asked questions about atorvastatin

Is 20mg of atorvastatin a low dose?

Yes, 20mg is considered a low to moderate dose of atorvastatin. It’s often used as a starting dose or for people with a lower cardiovascular risk. Your GP will review whether your dose needs adjusting based on your cholesterol levels and health history.

What is considered a high dose of atorvastatin?

80mg is the highest dose of atorvastatin available and is reserved for people at high risk of cardiovascular events, like those who have already had a heart attack or stroke. It’s not typically the first dose prescribed.

Is atorvastatin a blood thinner?

No, atorvastatin is not a blood thinner. It lowers cholesterol by reducing how much cholesterol your liver produces, rather than affecting how your blood clots. If you need a blood-thinning medicine, that will be prescribed separately.

Does atorvastatin cause weight gain?

Weight gain is not a commonly reported side effect of atorvastatin. There is no strong clinical evidence linking atorvastatin directly to weight gain. If you notice unexplained changes in your weight while taking it, speak to your GP.

Can I take atorvastatin and paracetamol?

Yes, paracetamol is generally safe to take alongside atorvastatin. There are no known significant interactions between the two. Always follow the recommended dose for paracetamol and speak to a pharmacist if you are unsure.
