Reminder:
If you give your pets heartworm preventative medication on the first…it’s the first!
Heartworm Preventative Medication
The following is a list of prescription medications available in varying combinations and permutations from your veterinarian. (If you see any I missed, let me know and I will add them!) Getting the weight-based dose and species correct is super important AND your veterinarian has your pet’s medical history which could impact which preventative is ideal. So please get your veterinarian’s input in choosing which medication is best for your pet!
The brand names are listed first, with the active ingredient against heartworm disease in parenthesis. Many of these medications also protect against other parasites. I can add that information too if you would like! You really only need to know which meds YOUR pet is on, but isn’t veterinary information FUN??
Dogs
Heartgard Plus (ivermectin) – monthly oral medication
Iverhart Max (ivermectin) – monthly oral medication
Tri-heart Plus (ivermectin) – monthly oral medication
Wormshield (ivermectin) – monthly oral medication
Interceptor (milbemycin) – monthly oral medication
Sentinel (milbemycin) – monthly oral medication
Trifexis (milbemycin) – monthly oral medication – new!
Advantage Multi (moxidectin) – monthly topical medication
Revolution (selamectin) – monthly topical medication
Proheart 6 (moxidectin) – sustained release injectable medication, given every six months (a form given every twelve months, Proheart 12, is available in Australia and parts of Asia)
Cats
Heartgard (ivermectin) – monthly oral medication
Interceptor (milbemycin) – monthly oral medication
Advantage Multi (moxidectin) – monthly topical medication
Revolution (selamectin) – monthly topical medication
Ferrets
Heartgard (ivermectin) – monthly oral medication
My checklist for today:
Noodle the Poodle – Wormshield tablet
Joy the Puppy – Proheart injection
Max the Cat – topical Revolution
Princess the Gerbil – no prophylaxis needed*
*Since Princess is not susceptible to heartworm disease, she, Max and Joy get snacks since Ebony and Noodle get oral medication so as not to feel left out, which they would all argue is MORE important than having a heartworm-free household.
