Get emergency medical help if you have signs of an allergic reaction to atorvastatin: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
In rare cases, atorvastatin can cause a condition that results in the breakdown of skeletal muscle tissue, potentially leading to kidney failure. Call your doctor right away if you have unexplained muscle pain, tenderness, or weakness especially if you also have fever, unusual tiredness, and dark colored urine.
Also call your doctor at once if you have:
muscle weakness in your hips, shoulders, neck, and back
trouble lifting your arms, trouble climbing or standing;
liver problems - upper stomach pain, weakness, tired feeling, loss of appetite, dark urine, jaundice (yellowing of the skin or eyes); or
kidney problems - little or no urinating, swelling in your feet or ankles, feeling tired or short of breath.
Common atorvastatin side effects may include:
joint pain;
stuffy nose, sore throat;
diarrhea; or
pain in your arms or legs.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
