Types OF Heartworm Preventative Meds
When choosing a heartworm medication for our pets we usually begin by deciding what we want for flea and tick control first
and then go from there. For instance, for our cats, Revolution topical spot on is our favorite flea and tick control method and it already
has a heartworm medication in it, so additional heartworm prevention is not necessary. For our dogs, we like Frontline flea and tick control.
Frontline is a topical so it doesn't make sense to us to apply two topicals at once. So for our dogs we use a
heartworm pill instead, usually Iverhart Plus tabs.
Most of the popular heartworm pills such as Heartgard Plus and Iverhart are for dogs only. This is because they contain
extra ingredients in addition to the heartworm preventative that can be harmful to cats. These ingredients are usually
included to help broaden the scope of parasite control the heartworm med has to offer. However, Heartgard does make an
Ivermectin only heartworm product for cats - just remember it is not the one with a "Plus" on the end of its name.
There are several pills on the market today including Trifexis, Heartgard, Iverhart, Tri-Heart, Sentinel and Interceptor.
Trifexis, Interceptor and Sentinel all contain Milbemycin Oxime to fight heartworms.
There is currently a shortage of Novartis products due to manufacturing updates so Sentinel and Interceptor
are hard to find these days, even online. Consequently, Trifexis has become quite a popular choice among pet owners.
Heartgard, Iverhart and Tri-Heart use a different ingredient than milbemycin oxime to fight heart worms, they use
Ivermectin instead. All three of the "Plus" varieties of these brands are for dogs and vary only slightly in
design from one another - however, the difference in price can be quite substantial at times.
When it comes to choosing
a heartworm pill for your dog or cat it usually comes down to price and ingredients.
One important thing to consider when choosing
a heartworm pill, is to pay attention to your pet's allergies. For instance, Heartgard and Tri-Heart are beef based, so if your dog is
allergic to beef you might want to choose a pork based product instead. Iverhart is a pork liver based and flavored med.
Trifexis, Sentinel and Interceptor are all beef flavored but the
flavoring is artificial, and like Iverhart, they are actually made from pork liver.
Monthly Heartworm Topical Spot Ons
Depending on what other parasites you want to target, there are a few monthly, topical spot on
heartworm preventatives to choose from for pets these days, including Revolution and Advantage Multi -
both of which offer one variety for dogs and another for cats too.
Just a drop or two between the shoulder blades once a month does the trick. Both products also
help control fleas and Revolution goes one step further to help control ticks. Both help control
their own specific group of other parasites too. Topicals spot ons can be a nice option when you
are looking for comprehensive coverage or simply when you have trouble getting your pets to take a pill.
