Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. Antacids are a type of medication used to neutralize stomach acid and treat conditions such as heartburn and acid reflux.

According to Drug Patent Watch [1], there are no known interactions between Lipitor and antacids. However, it is recommended to take Lipitor at least two hours before or after taking an antacid to avoid any potential interactions.

GoodRx [2] also lists no significant interactions between Lipitor and antacids, but it is important to note that antacids can interfere with the absorption of other medications, so it is always best to check with a healthcare provider or pharmacist before taking any new medications together.

Verywell Health [3] notes that certain antacids containing aluminum and magnesium can decrease the absorption of some statins, including Lipitor. Therefore, it is recommended to avoid taking these types of antacids within two hours of taking Lipitor.

In conclusion, while there are no known significant interactions between Lipitor and antacids, it is still important to take precautions and avoid taking them together within two hours of each other. It is always best to consult with a healthcare provider or pharmacist before taking any new medications together.
