Why you need to ask your vet about pet drug interactions & side effects

Discuss potential medication side effects with your vet

In the middle of a busy veterinary practice, many veterinarians may overlook an opportunity to discuss the possibilities of drug interactions and pet medication side effects. For example, many commonly prescribed nonsteroidal anti-inflammatory medications (NSAIDs) can sometimes cause digestive upset and/or liver/kidney problems in some sensitive pets. Corticosteroids like Prednisone can cause similar problems in some pets, as well as predispose pets to diabetes with prolonged use.

While a topic of debate, these risks are increased if Prednisone and nonsteroidal anti-inflammatory drugs are used together.

While potentially lifesaving, antibiotics can also cause allergic reactions from digestive upset to skin irritation. Some pets are sensitive to topical flea and tick medications, and in my practice I always administer topical flea and tick medication on a separate day from heartworm preventative medication or vaccinations, in order to lessen the burden on a pet’s immune system.

Whenever multiple drugs are prescribed it is always important for pet owners to ask questions, because veterinarians not only prescribe pet medication but are also dispensing these medications in private practice.

  1. Trying to figure out the best times/combos with all the meds we are juggling. (Pepcid, prednisone bid, gabapentin bid, denamarin, atopica)
    Seems denamarin first thing on an empty stomach works. Wait 1 hr to give pepcid,prednisone, gabapentin. Then with dinner gabapentin and prednisone. Another 2hrs no food before atopica.

    Are they spread out enough? Anything I should do differently.

  2. can i use frontline on my 8lb morkie even though she is on phenobarbital?
