Does milk increase or decrease lipitor's absorption?

Milk typically decreases Lipitor (atorvastatin) absorption somewhat.

• Why: Milk (especially due to its calcium) can reduce absorption of some medications by affecting how they dissolve/are taken up in the gut.
• For atorvastatin: Taking atorvastatin with dairy can reduce peak blood levels (Cmax) and overall exposure (AUC), though the effect is usually modest.

Practical tip:

• If you take Lipitor with meals, that’s generally fine—just try to be consistent about whether you take it with or without dairy.
• If you’re also on supplements that contain calcium, magnesium, or antacids, separate them from Lipitor by a couple of hours if your clinician/pharmacist recommends it.

If you tell me how you take it (with food or on an empty stomach) and whether you mean milk with the dose or milk later in the day, I can give more tailored guidance.
