Muscle Pain, Extreme Tiredness, or Forgetfulness on a Statin Can Be Signs to Tell Your Doctor. What Older Adults Should Know

Sore legs after yard work. A heavy, drained feeling by midafternoon. Walking into a room and forgetting why. Plenty of things can cause those. If you take atorvastatin, they are also worth mentioning to your doctor.

Atorvastatin is a cholesterol medicine in the class known as statins. MedlinePlus says atorvastatin is used to reduce the risk of heart attack and stroke and to lower the amount of cholesterol in the blood. It works by slowing how much cholesterol the body makes, which lowers the amount that can build up on artery walls and block blood flow.

That benefit is the reason not to change anything on your own. MedlinePlus says to keep taking atorvastatin even if you feel well, and not to stop taking it without talking to your doctor. The point of knowing the side effects is to report them, not to quit.

Side effects to tell your doctor about if they are severe or do not go away. MedlinePlus lists diarrhea, heartburn, gas, joint pain, forgetfulness or memory loss, and confusion. Memory changes and confusion in particular are easy to blame on age, so it helps to note when they started.

Symptoms MedlinePlus calls serious. These are uncommon, MedlinePlus says, but if you have any of them, call your doctor or get emergency medical help right away:

Muscle trouble. Muscle pain, tenderness, or weakness.

Low energy. Lack of energy, extreme tiredness or weakness, fever, or flu-like symptoms.

Possible liver signs. Nausea, unusual bleeding or bruising, loss of appetite, pain in the upper right part of the stomach, dark-colored urine, or yellowing of the skin or eyes.

Allergic-type reactions. Rash, itching, hives, difficulty breathing or swallowing, swelling of the face, throat, tongue, lips, eyes, hands, feet, ankles, or lower legs, or hoarseness.

Chest pain. MedlinePlus lists it separately.

Why age matters. Before starting atorvastatin, MedlinePlus says to tell your doctor if you are 65 or older, if you drink more than two alcoholic beverages a day, and if you have or have ever had muscle aches or weakness, diabetes, seizures, low blood pressure, or thyroid or kidney disease. It also says to ask your doctor about the safe use of alcohol, because alcohol can increase the risk of serious side effects.

Other medicines and foods. MedlinePlus says to tell your doctor and pharmacist about every prescription and nonprescription medicine, vitamin, supplement, and herbal product you take. It names two nonprescription products that may interact with atorvastatin, cimetidine and niacin, and says not to start either without talking with your provider. It also advises talking to your doctor about eating grapefruit or drinking grapefruit juice.

Lab work. MedlinePlus says your doctor will order tests to check how well your liver is working, and may order more lab tests during treatment, especially if you develop symptoms of liver damage. It also says to keep all appointments with your doctor and the laboratory, and to tell lab staff you take atorvastatin before any test.

What you can do. Keep a short log of any new symptom, when it started, and whether it is getting better or worse. Bring an up-to-date list of your medicines and supplements to every visit, which MedlinePlus also recommends. If you have a serious side effect, MedlinePlus notes that you or your doctor can report it to the Food and Drug Administration’s MedWatch program online or by phone at 1-800-332-1088.

The goal is a conversation, not a guess. Only your doctor can sort out whether a symptom is tied to the medicine, and whether a different dose or option makes sense.
