When Should You Take Your Cholesterol Medication?
Some statins work better at night, while others can be taken any time of day. Learn the best timing for your specific cholesterol medication.
Cholesterol Production Peaks at Night
Your liver produces the most cholesterol during the late evening and early morning hours, when dietary intake is lowest. This is why some statin medications, particularly the older short-acting ones, are recommended to be taken at bedtime to coincide with peak cholesterol production.
Short-Acting Statins: Take at Night
Simvastatin (Zocor), lovastatin (Mevacor), and fluvastatin (Lescol) are shorter-acting statins with half-lives of a few hours. These medications are most effective when taken in the evening because their peak activity aligns with the body's peak cholesterol synthesis. Studies have shown that taking simvastatin in the morning reduces its LDL-lowering effect by 15 to 20 percent compared to evening dosing.
Long-Acting Statins: Any Time of Day
Atorvastatin (Lipitor) and rosuvastatin (Crestor) have much longer half-lives, remaining active in the body for 14 to 20 hours or more. This means they provide cholesterol reduction regardless of when they are taken. For these medications, the best time is whenever you are most likely to remember consistently.
Taking Statins With or Without Food
- Lovastatin should be taken with food to improve absorption
- Simvastatin, atorvastatin, and rosuvastatin can be taken with or without food
- Avoid taking statins with large amounts of grapefruit juice, which can increase drug levels
What About Other Cholesterol Medications?
Ezetimibe (Zetia) can be taken at any time of day and is not affected by food. Bile acid sequestrants like cholestyramine are usually taken with meals. PCSK9 inhibitors are injectable medications given every two to four weeks at any time of day.
