This will help to ensure that Lipitor is properly absorbed and can work effectively to lower cholesterol levels.

It is also important to talk to your healthcare provider or pharmacist before taking Lipitor or any other medication with antacids. They can provide personalized advice and guidance on how to take your medications safely and effectively.

In conclusion, while there is no specific information on how long one should wait to take Lipitor after antacids, it is recommended to take Lipitor at least two hours before or after taking antacids to ensure proper absorption [2][3].
