A small number of people report feeling nauseated.
If nausea continues or becomes severe, your healthcare provider should know about it.
7. Diarrhea
Loose stools or diarrhea can occur with many medications, including atorvastatin.
Persistent diarrhea should always be discussed with a healthcare professional.
8. Constipation
Some people experience constipation instead of diarrhea.
Changes in diet, hydration, activity, and other medications may also contribute.
9. Fatigue
Feeling unusually tired is occasionally reported.
Because fatigue is one of the most common symptoms in medicine, it should never automatically be blamed on atorvastatin without considering other possible explanations.
10. Sleep Changes
Some people notice changes in their sleep after starting a statin.
Research has produced mixed findings, and sleep problems can have many unrelated causes.
If you notice a persistent change, mention it during your next medical appointment.
11. Dizziness
Occasional dizziness has been reported by some people taking atorvastatin.

Because dizziness has many potential causes, it deserves proper medical evaluation if it continues or becomes severe.
12. Memory Changes or Confusion
Some people have reported memory problems or difficulty concentrating while taking statins.
The evidence is mixed, and memory changes are common with aging and many other medical conditions.
If you notice new cognitive symptoms, discuss them with your doctor rather than assuming the medication is responsible.
13. Increased Liver Enzymes
Atorvastatin can sometimes affect the liver.
This usually causes no symptoms and is found only through blood tests when your doctor decides monitoring is appropriate.
Serious liver problems are uncommon.
14. Allergic Reactions
Although uncommon, allergic reactions can occur with almost any medication.
Seek medical attention immediately if you develop symptoms such as swelling of the face, lips, tongue, or throat, difficulty breathing, or a widespread rash.
15. Rare Severe Muscle Injury
A very rare but serious complication involves significant muscle damage.
Warning signs can include severe muscle pain or weakness together with dark-colored urine.
Although uncommon, this requires prompt medical attention.
