9. Liver Enzyme Changes
Atorvastatin can affect liver enzymes.
This does not necessarily mean that the liver has been seriously damaged. Doctors can use blood tests to monitor liver function when appropriate.
More serious liver problems are rare, but symptoms such as yellowing of the skin or whites of the eyes, unusually dark urine, or feeling significantly unwell should be reported promptly.
10. Nausea
Feeling sick or nauseated is another possible side effect.
For some people, this improves as the body becomes accustomed to the medication.
If nausea is persistent or severe, however, talk with your doctor or pharmacist rather than discontinuing the medication without advice.
11. Joint or General Body Discomfort
Some people report aches involving muscles or joints while taking atorvastatin.
Because these symptoms are also extremely common as people age, determining whether atorvastatin is actually responsible can require a careful medical assessment.
Your doctor may consider your symptoms, other medicines, medical conditions, physical activity, and sometimes laboratory testing.
12. Increased Blood Sugar
Statins can be associated with a small increase in blood glucose and may slightly increase the risk of developing type 2 diabetes in some people.
That does not mean most people should stop statin treatment.
For people who have a significant cardiovascular risk, the benefits of statins in preventing heart attacks and strokes can outweigh this potential risk. Your doctor can consider your individual circumstances and monitor blood glucose when appropriate.
13. Allergic Reactions
Serious allergic reactions to atorvastatin are uncommon, but they can occur.
A severe allergic reaction may involve:
- Swelling of the face, lips, tongue, or throat
- Difficulty breathing
- A widespread itchy rash
- Severe swelling
These symptoms require urgent medical attention.
