When it comes to preventing heartworm disease, there are many options for dog owners. Each of these products has its own unique properties and should be used under the advisement of your veterinarian. Here we’ll discuss the active ingredients in several popular heartworm preventatives and list their pros and cons.
There are many options for preventing heartwom disease, but certain drugs tend to be more effective than others.
Heartworm prevention is available in two forms: monthly and annual. The monthly treatments tend to be more effective at preventing heartworm disease, but the annual treatments have their uses as well.
Annual medications that prevent fleas and ticks can also act as heartworm medications, so if you’re concerned about these parasites as well, an annual medication may be a good choice for you.
The active ingredient in ProHeart 6 is a drug called Moxidectin.
ProHeart 6 is a chewable tablet that contains Moxidectin, an ingredient used to prevent and treat heartworm disease.
Moxidectin is a drug that works by killing heartworms that have already entered the bloodstream. It also prevents new worms from growing in your dog’s body. After it has been taken orally by a dog, moxidectin moves through the bloodstream and kills immature heartworms, as well as adult worms living in the pulmonary arteries and veins of dogs.
Heartgard is the only heartworm preventive that contains Ivermectin.
Ivermectin is an older, off-patent drug that was developed as a broad-spectrum antiparasitic to treat cattle with worms and other parasites. Ivermectin has now been shown to be very effective in treating heartworms in dogs, but it’s not the best choice for preventing fleas or ticks.
Interceptor is the most effective monthly heartworm preventive.
Interceptor is the most effective monthly heartworm preventive. Interceptor is the only heartworm preventive that contains milbemycin oxime. Milbemycin oxime kills adult heartworms for up to twelve months in dogs and cats, and prevents infection of larvae for up to six months in your pet.
Interceptor also contains lufenuron, which breaks down into metabolites that kill fleas by disrupting flea development at all stages of development and reduces growth rate of immature fleas.
Research shows patients given Trifexis have 4 times less fleas than others who use Nexguard.
Trifexis is a monthly chewable tablet that combines spinosad, an insecticide that kills fleas, and milbemycin oxime, a heartworm preventative. The combination of these two drugs treats and prevents intestinal worms such as hookworms and roundworms in dogs.
Trifexis has been shown to be highly effective at treating flea infestation in dogs. In one study, it was found to kill over 98% of fleas within 30 minutes after administration. The medication also kills adult fleas before they lay eggs so fewer eggs are produced overall compared with other medications on the market today (Nexgard).
Sentinel comes in various strengths based on your dog’s weight.
Sentinel comes in various strengths based on your dog’s weight. Sentinel is a monthly chewable tablet that protects against heartworm, fleas and other parasites. It comes in three sizes: Heartgard, Interceptor and Proheart 6. The size of the pill depends on how much your dog weighs; the higher the dose, the more it costs.
In summary, using these drugs will prevent heartworm disease. There is no cure for heartworm disease once it has developed. Heartworms are a parasite that only affects dogs, but they can be transmitted to humans through mosquito bites.
