Atorvastatin is generally well tolerated, and the phrase “15 hidden side effects your doctor may not have time to mention” is more sensational than medically useful. Still, there are side effects and warning signs worth knowing.
Possible side effects
Some people taking atorvastatin may experience:
-
Muscle aches or soreness
-
Muscle weakness
-
Headache
-
Nausea
-
Diarrhea
-
Constipation
-
Indigestion
-
Abdominal discomfort
-
Fatigue
-
Sleep disturbances
-
Mild increases in blood glucose
-
Changes in liver enzymes
-
Joint or back pain
-
Rarely, memory or concentration complaints
-
Rare but serious muscle injury (rhabdomyolysis)
Most of these aren’t dangerous and may improve as the body adjusts. The serious concern is unexplained or severe muscle pain/weakness, particularly if accompanied by dark urine or marked fatigue. That warrants prompt medical evaluation.
Don’t stop it because of a headline
Atorvastatin reduces LDL cholesterol and can substantially reduce cardiovascular risk in appropriate patients. If you suspect a side effect, talk with your clinician rather than simply skipping doses or stopping treatment. Sometimes the dose can be adjusted or another statin considered.
Also tell your doctor or pharmacist about all medicines and supplements you take, because some combinations can increase the risk of atorvastatin-related muscle problems.
If you’re taking atorvastatin now, tell me your dose and any symptoms you’ve noticed, and I can help you determine whether they are recognized side effects and how urgent they are.
