Everyone has cholesterol and triglycerides in their blood. They are fatty substances needed by the body for many things. There are different types of cholesterol. Too much of the “bad” cholesterol can block the blood vessels that supply your heart and brain with blood, and can cause heart attack, angina and stroke. The “good” cholesterol helps to remove the bad cholesterol from the blood vessels. Atorvastatin is used to lower the level of cholesterol in your blood.

Atorvastatin can also reduce your chance of heart disease if you have an increased risk of it, even if your cholesterol levels are normal.

Atorvastatin belongs to a group of medicines called statins. Read more about statins.

Atorvastatin tablets are available in different strengths: 10 mg, 20 mg, 40 mg and 80 mg.

The dose of atorvastatin will depend on your cardiovascular disease (CVD) risk, which is calculated by completing a heart risk assessment. Your doctor will discuss your CVD risk with you and then determine what dose of atorvastatin is best for you.
Always take your atorvastatin exactly as your doctor has told you.
The pharmacy label on your medicine will tell you how much atorvastatin to take, how often to take it and any special instructions.

Timing: Take atorvastatin once a day, at around the same time each day. You can take atorvastatin with or without food.
Avoid large quantities of grapefruit: Having large quantities of grapefruit while taking atorvastatin can increase your risk of side effects. But, eating one serving of marmalade, no more than half a grapefruit or drinking no more than a standard glass (250 mL) of grapefruit juice each day, should not be a problem if you are taking statins. It's best to allow 12 hours between having these foods and taking your atorvastatin dose, so if you take your statin in the morning have your grapefruit at night.
Limit drinking large amounts of alcohol while you are taking atorvastatin: Heavy drinking can increase your risk of side effects such as problems with your liver.
Missed dose: If you forget your dose, take it as soon as you remember that day. But, if it is nearly time for your next dose, just take the next dose at the usual time. Do not take double the dose.
Keep taking atorvastatin regularly: To reduce your cholesterol effectively, you must keep taking atorvastatin every day. Treatment with atorvastatin is usually long term.

Here are some things to know when you're taking atorvastatin. Other things may be important as well, so ask your healthcare provider what you should know about.

You may need to see your doctor regularly when you first start taking atorvastatin to make sure the dose is right for you.
To get the full benefit of a statin, it's important to keep to a healthy diet and exercise often.
Other medicines: Atorvastatin can interact with some medicines and herbal supplements, so check with your doctor or pharmacist before starting atorvastatin or before starting any new medicines or supplements.

Like all medicines, atorvastatin can cause side effects, although not everyone gets them. Often side effects improve as your body gets used to the new medicine.

Muscle pain or weakness

Some people will have muscle pain or weakness when taking statins. This is rarely serious and often goes away with time. If your pain comes on shortly after you start your statin, or gets worse, see your doctor. Your doctor will check an enzyme called creatine kinase to see if the aches and pains are possibly being caused or made worse by the statins. If so:

a lower dose or a different statin may be prescribed, or
you may choose to continue living with the aches because of the benefits of the statin, or
you may discuss stopping taking your statin with your doctor.

Your doctor will also want to check for a rare but serious condition called rhabdomyolysis and will check any other medicines you are taking. Rhabdomyolysis can be caused by an interaction between statins and some other medicines including antibiotics.
