Atorvastatin
Cholesterol Medication (Statin)
1. What is atorvastatin used for?
Atorvastatin is a cholesterol-lowering medication from the statin family. It is one of the most commonly prescribed medications in Canada.
Atorvastatin is used to:
- Lower "bad" LDL cholesterol
- Lower triglycerides (a type of blood fat), in some cases
- Slightly raise "good" HDL cholesterol
- Reduce the risk of heart attack and stroke in people at higher risk
💡 Good to know
Statins like atorvastatin have been studied for many years and are among the most commonly used medications to protect the heart and blood vessels in older adults.
2. How does atorvastatin usually help?
Atorvastatin works mainly by:
Blocks an enzyme in your liver that makes cholesterol
Helps your body remove "bad" LDL cholesterol from your blood
May help stabilize fatty plaques in arteries, reducing risk of rupture
Over time, this can help slow the build-up of fatty plaques in arteries and reduce the chance of heart attacks, strokes, and other blood vessel problems.
3. Why atorvastatin needs extra care in older adults
In older adults, statins like atorvastatin may need extra attention because:
- Muscle aches or weakness may be more common
- Kidney or liver function may be reduced
- Many older adults take several medications that could interact
- Overall health goals may differ from younger people

4. How atorvastatin is usually taken
⚠️ Important
Follow the exact instructions from your doctor or nurse practitioner. Do not change your dose on your own.
In general:
Atorvastatin is usually taken once a day
Can be taken at any time, with or without food
Pick a time that is easy to remember and stick with it
❓ If you miss a dose
Take it as soon as you remember, unless it is almost time for your next dose. Do not take two doses at once. If unsure, ask your pharmacist.
🍊 Note about grapefruit
Grapefruit and grapefruit juice can increase the amount of atorvastatin in your body, which may increase the risk of side effects. Ask your provider if you need to avoid grapefruit.
5. Possible side effects older adults may notice
Not everyone has side effects. Common ones can include:
Most common side effect – tell your provider if this happens
Some people notice aches in their joints
Usually mild and may improve over time
Some people experience headaches
💡 About muscle symptoms
Mild muscle aches are fairly common. However, if you have severe muscle pain, tenderness, or weakness – especially with fever or feeling unwell – tell your provider right away. This could be a sign of a rare but serious problem.
⚠️ Rare but serious – tell your provider right away if:
- You have severe muscle pain, tenderness, or weakness
- You notice dark-coloured (brown or cola-coloured) urine
- You feel unusually tired or weak without a clear reason
- You have yellowing of your skin or eyes (jaundice)
6. When to be extra careful with atorvastatin
Talk to your health-care provider before taking atorvastatin if you have:
💊 Drug interactions
Some medications can interact with atorvastatin and increase the risk of muscle problems. Always tell your provider about all medications, vitamins, and supplements you take, including over-the-counter products.
7. Habits and lifestyle that may help
Atorvastatin works best as part of an overall heart-healthy plan. In general, providers often recommend:
More vegetables, fruits, whole grains, and fish; less saturated fat and processed foods
Olive oil, canola oil, nuts, and avocado instead of butter and fried foods
Regular walking or gentle exercise as approved by your provider
Smoking greatly increases heart and blood vessel risks
Maintaining a healthy weight can help cholesterol levels
If you drink, keep it moderate – ask your provider what is safe for you
✅ Always ask first
Ask your doctor, nurse practitioner, or dietitian what food and activity changes are safe and realistic for you, especially if you have diabetes, kidney disease, or other health conditions.
