Atorvastatin (brand name: Atorvastatin) is a statin medication commonly prescribed to lower LDL (“bad”) cholesterol and reduce the risk of heart attack and stroke. Most people tolerate it well, but like any medication, it can cause side effects.
Common side effects
These are usually mild and may improve as your body adjusts to the medication:
- Muscle aches, tenderness, or mild weakness
- Joint pain
- Headache
- Nausea or indigestion
- Diarrhea or constipation
- Fatigue
- Cold-like symptoms such as a runny nose or sore throat
Less common but important side effects
Muscle problems
Statins can sometimes cause more significant muscle-related issues:
- Persistent muscle pain, tenderness, or weakness
- Muscle symptoms that interfere with daily activities
- Rarely, a severe condition called Rhabdomyolysis, which can damage the kidneys
Seek medical attention promptly if you develop severe muscle pain, weakness, or dark-colored urine.
Liver effects
Atorvastatin can occasionally affect liver function.
Contact your healthcare provider if you notice:
- Yellowing of the skin or eyes (jaundice)
- Dark urine
- Unusual fatigue
- Persistent abdominal pain
- Loss of appetite
Blood sugar changes
Statins may slightly increase blood sugar levels and can occasionally contribute to the development of Type 2 Diabetes in people who are already at risk. However, for most patients, the cardiovascular benefits outweigh this risk.
Rare side effects
Rarely reported side effects include:
- Memory problems or confusion
- Allergic reactions (rash, swelling, difficulty breathing)
- Peripheral neuropathy (numbness or tingling in the hands or feet)
Factors that can increase side-effect risk
Your risk may be higher if you:
- Take higher doses of atorvastatin
- Are older
- Have kidney or liver disease
- Take certain interacting medications
- Drink large amounts of alcohol
Grapefruit interaction
Large amounts of grapefruit or grapefruit juice can increase atorvastatin levels in the body, potentially increasing the risk of side effects.
When to contact a healthcare professional
Contact your doctor if you experience:
- Persistent or bothersome muscle pain
- Significant weakness
- Symptoms of liver problems
- Signs of an allergic reaction
- Any new or unusual symptoms that concern you
Important perspective
Many people take atorvastatin for years without significant problems. If you develop side effects, do not stop the medication on your own unless advised by a healthcare professional. Often, adjusting the dose or switching to a different statin can help while maintaining protection against heart disease and stroke.
