Both medications are commonly used for different purposes and can be taken together if prescribed by a healthcare professional. Lipitor is a statin medication used to lower cholesterol levels, while Pepcid is an H2 blocker used to treat and prevent ulcers by reducing stomach acid.

When two medications are taken together, there is a potential for a drug-drug interaction, which can affect the effectiveness or side effects of either medication. However, according to the information provided, there is no known interaction between Lipitor and Pepcid.

It is important to note that drug interactions can be complex, and this information may not include all possible interactions. Therefore, it is always best to consult with a healthcare provider or pharmacist before starting or changing any medications.
