Your Azelaic Acid Irritation Might Be a Formula Problem — Derm Explains

A lot of you guys have the same 15% azelaic acid prescription, but you have completely different experiences. So this is something that a lot of you don't recognize. When a pharmacist gives you a generic 15% prescription of azelaic acid, it's made by a certain manufacturer. Could be manufacturer A, B, or C. Each one of these manufacturers are going to cook slightly differently. So the 15% A prescription could be different in terms of the experience from the 15% C prescription. One thing you have the right to ask your pharmacist as a person and as a human and as a patient is, can I get another generic prescription from a different manufacturer? Because maybe it is the way that manufacturer A cooked doesn't sit well for your taste buds and you want manufacturer C's version instead.
