Taking Atorvastatin? 15 Possible Side Effects You Should Know About
Atorvastatin (a statin medication) is commonly prescribed to lower LDL (“bad”) cholesterol and reduce the risk of heart attack and stroke. Many people take it safely, but like all medicines, it can cause side effects in some individuals.
Here are 15 possible side effects and effects to be aware of:
1. Muscle Aches or Pain
Some people experience soreness, tenderness, or weakness in muscles. Mild muscle symptoms are among the more commonly reported concerns with statins.
2. Muscle Weakness
Unusual difficulty climbing stairs, lifting objects, or performing normal activities should be discussed with a healthcare professional.
3. Fatigue
Some people report feeling more tired than usual after starting treatment, although fatigue can have many causes.
4. Headache
Headaches may occur, particularly after beginning a new medication.
5. Digestive Problems
Possible symptoms include:
- Nausea
- Diarrhea
- Constipation
- Indigestion
- Stomach discomfort
6. Changes in Liver Enzymes
Atorvastatin can cause increases in liver enzymes in some people. Doctors may check liver function if there are concerns.
