Saw this in my Whole Dog Journal update. I've called in for a refill from my vet. I'm a bit nervous about a shortage.
Thanks - that's helpful. I was looking at the comparison charts, too. I guess I'm debating whether just going to Iverheart would be okay. I don't know enough about the different ingredients to judge them. I will obviously talk to my vet, too.Sentinel IS Interceptor with Flea Prevention added. So if you were using Sentinel you would not need the separate flea treatment. On Interceptor you would.
Neither one is manufactured anymore. Milbemycin Oxime was the active ingredient for heartworm prevention in both. Lufenuron was added to Sentinel for flea control.
Iverhart is similar to Interceptor in that it does heartworms but NOT fleas. So on it you would want to keep the separate flea treatment.
Active ingredients are Ivermectin and Pyrantel.
Trifexis is similar to Sentinel, still uses Milbemycin Oxime for heartworm control but uses Spinosad instead of Lufenuron for flea control.
I've never ordered from Heartworm Preventative Medicine for Dogs and Cats - 1800PetMeds but I am really appreciating their comparison charts and ingredient breakdowns.
This makes a lot of sense - thanks. I don't think I need to be worried about whipworms, but I suspect your first two reasons are why my vet prefers it. I'm with you on reason three - I try to keep our "drugs" to a minimum, if possible.I prefer Interceptor because 1) We've recently had to deal with whipworms and it's the only heartworm preventative that covers them (besides Trifexis) 2) It's been on the market a long time and has a great track record re: safety, and 3) I really like that it's just one ingredient. I'm a minimalist when it comes to pesticides and my pets.
