What side effects can Lipitor (atorvastatin) cause?
Lipitor (atorvastatin) is a statin used to lower cholesterol. Like other statins, it can cause side effects ranging from mild muscle aches to rare but serious muscle injury and liver problems.
Commonly reported side effects include:
- Muscle pain, tenderness, or weakness
- Joint pain
- Digestive symptoms such as nausea, diarrhea, or constipation
- Headache
What are the serious side effects people should watch for?
Serious adverse effects are less common, but they are important to recognize early:
- Muscle injury (myopathy or rhabdomyolysis). Watch for severe muscle pain, weakness, or dark/cola-colored urine.
- Liver problems. Watch for unusual fatigue, loss of appetite, upper abdominal pain, dark urine, or yellowing of the skin/eyes.
- Allergic reactions. Seek urgent care for swelling of the face/lips, trouble breathing, or widespread rash.
- Increased risk of blood sugar or worsening diabetes in some patients.
Who is more likely to get muscle-related side effects?
The risk of statin muscle problems can be higher with certain patient factors and medication combinations, such as:
- Higher statin doses
- Older age
- Kidney or liver problems
- Hypothyroidism (untreated)
- Use of interacting drugs (some antibiotics, antifungals, HIV/HCV antivirals, and other lipid-lowering medicines)
When should you call a doctor or stop Lipitor?
Seek medical attention promptly if you develop:
- Severe or unexplained muscle pain/weakness, especially with fever or feeling very ill
- Dark urine
- Signs of liver injury (yellow skin/eyes, severe fatigue, significant abdominal pain)
Do not stop Lipitor on your own without medical guidance, but contact the prescribing clinician right away if these symptoms occur.
Are there differences vs other statins?
Side effects like muscle aches and liver enzyme elevations can happen with any statin. Some people tolerate one statin better than another, so clinicians may adjust dose or switch drugs if side effects occur.
What alternatives exist if Lipitor side effects happen?
If Lipitor is not tolerated, options can include:
- Lowering the dose
- Switching to a different statin
- Using non-statin cholesterol-lowering therapies (depending on the reason it was prescribed)
