• 20 mg is the strength of each tablet.
• It is usually taken once daily, but follow the prescription you were given.
• Possible side effects include headache, stomach upset, or muscle aches.
• Do not change or stop it on your own, especially if it was prescribed for a specific cholesterol or heart condition.
