- Cholesterol Levels: The initial cholesterol level may determine the starting dose and necessary adjustments.
Assessing Effectiveness and Safety
Regular monitoring of cholesterol levels and liver function tests is recommended to ensure the effectiveness and safety of atorvastatin therapy. Patients should have follow-up appointments with their healthcare providers to assess lipid levels and evaluate any side effects.
Potential Side Effects
While atorvastatin is generally well-tolerated, some individuals may experience side effects. Common side effects may include:

If any severe side effects or symptoms arise, patients should seek medical attention immediately.
