{"chart":{"slug":"atorvastatin-side-effects-reported","title":"Which side effects are reported most for atorvastatin?","takeaway":"Fatigue (14,619 reports), nausea and diarrhea are the reactions named most often in the reports to the FDA, as of September 2026, that list atorvastatin (Lipitor) among a patient's medicines. Muscle pain, a known statin side effect, has about 10,000, and type 2 diabetes about 11,000; statin labels note they can raise blood sugar. A report is not proof the medicine caused the problem: anyone can send one, it lists every medicine the person was taking, and the same case can be reported twice. Reports that the medicine didn't work or was used differently than labeled are left out. Don't stop a medicine without talking to a doctor.","topic":"Food and drug safety","chart_type":"bar","ranking":false,"x_label":"Reported reaction","y_label":"Reports to the FDA naming atorvastatin","unit":null,"points_count":15,"source":{"name":"U.S. Food and Drug Administration, Adverse Event Reporting System (FAERS) via openFDA","url":"https://open.fda.gov/apis/drug/event/"},"license":{"name":"Public domain (U.S. government work); source U.S. Food and Drug Administration, openFDA","url":"https://open.fda.gov/license/"},"data_as_of":"2026-09-30","updated_at":"2026-11-03T17:17:15.665Z","url":"https://chart.ly/charts/atorvastatin-side-effects-reported","api_url":"https://chart.ly/api/v1/charts/atorvastatin-side-effects-reported","csv_url":"https://chart.ly/charts/atorvastatin-side-effects-reported/data.csv","image_url":"https://chart.ly/charts/atorvastatin-side-effects-reported/image.png","embed_url":"https://chart.ly/charts/atorvastatin-side-effects-reported/embed","credit":"U.S. Food and Drug Administration, Adverse Event Reporting System (FAERS) via openFDA, via Chartly (https://chart.ly/charts/atorvastatin-side-effects-reported)","credit_html":"U.S. Food and Drug Administration, Adverse Event Reporting System (FAERS) via openFDA, via \u003ca href=\"https://chart.ly/charts/atorvastatin-side-effects-reported\"\u003eChartly\u003c/a\u003e","average_label":null,"zero_axis":true,"data":[{"label":"Fatigue","value":14619},{"label":"Nausea","value":13086},{"label":"Diarrhea","value":11803},{"label":"Shortness of breath","value":11797},{"label":"Type 2 diabetes mellitus","value":11285},{"label":"Pain","value":10556},{"label":"Headache","value":10429},{"label":"Dizziness","value":10351},{"label":"Muscle pain","value":10091},{"label":"Weakness","value":9268},{"label":"Joint pain","value":8919},{"label":"Pain in an arm or leg","value":8453},{"label":"Falls","value":8240},{"label":"Death","value":7851},{"label":"Feeling unwell","value":7279}],"annotations":[]},"docs":"https://chart.ly/developers","terms":"Free to use with credit: wherever you show or quote a chart's data, name Chartly with a link to that chart's url (each chart's credit line does both) and credit its source as its license asks.","credit":"U.S. Food and Drug Administration, Adverse Event Reporting System (FAERS) via openFDA, via Chartly (https://chart.ly/charts/atorvastatin-side-effects-reported)"}
