Can my pet be allergic to chewable Heartworm disease prevention medication?
Yes. Pets can be allergic to medications for 2 reasons. First, they may be allergic to the medication itself, just like humans can be to penicillin. Second, they can be allergic to flavoring agents, such as beef, pork, corn, wheat, milk products, soy, brewers yeast, etc. For example, Interceptor has soy, pork, and milk (lactose). If a pet has allergies to these, consider switching to an unflavored product, or to a topical such as Revolution.
