What happens if you take dairy products, iron preparations, or antacids with a medication when told not to?
The short answer is that it probably blocks the absorption of the drug so that it can’t do its job. The truth of the matter is that this is a question best put to your health care provider of Pharmacist. Different drugs even in the same class can have different interactions. Frankly no matter the drug, prescription or OTC the directions and warnings are there for a reason and should be followed. For the short course of the treatment leaving out dairy should not present much issue. There are ways to replace dairy if necessary. Use soy or corn products for milk and cheese substitutes, margarine or olive oil instead of butter and simply don’t eat ice cream, yogurt, sour cream etc.
