The headline “Atorvastatin Side Effects: 15 Hidden Dangers Your Doctor Might Not Tell You About” is sensationalized. Doctors routinely discuss the most important risks and benefits of medications like atorvastatin, and for many people the benefits of reducing the risk of heart attack and stroke outweigh the risks.
Atorvastatin is a statin used to lower LDL (“bad”) cholesterol and reduce the risk of cardiovascular disease.
Some known side effects include:
- Muscle aches or soreness
- Muscle weakness (less common)
- Joint pain
- Digestive upset (nausea, diarrhea, or constipation)
- Headache
- Mild increases in liver enzyme blood tests
- Slightly increased risk of developing type 2 diabetes in some people already at risk
- Sleep disturbances or vivid dreams (reported by some people, but uncommon)
- Skin rash (uncommon)
- Rare allergic reactions
Rare but serious side effects
- Severe muscle injury (rhabdomyolysis): This is rare but can damage the kidneys. Seek medical attention if you develop severe muscle pain or weakness with dark-colored urine.
- Significant liver problems: Uncommon, but symptoms such as yellowing of the skin or eyes, dark urine, or severe fatigue should be evaluated promptly.
Important points
- Many people take atorvastatin for years without significant side effects.
- Muscle symptoms are one of the more common reasons people stop statins, but they are often mild and may have other causes.
- Do not stop atorvastatin on your own because stopping it can increase your risk of heart attack or stroke if it was prescribed to lower that risk.
If you think you’re having side effects, contact your healthcare professional. They may recommend:
- Checking whether the symptoms have another cause.
- Adjusting the dose.
- Switching to a different statin or another cholesterol-lowering medication.
- Ordering blood tests if appropriate.
If you tell me your age, dose (for example, 10 mg, 20 mg, or 40 mg), and the symptoms you’re experiencing, I can help explain whether they could be related to atorvastatin and what questions to discuss with your clinician.
