Dr. Lenzo's review of Flea and Tick and Heartworm Medications

1 My Picks for Fleas and Ticks!
    A) Best Flea and Tick Meds - Nexgard and Bravecto
    B) Best Heartworm Preventative - Sentinel Spectrum
    C) Best Combination Flea and Heartworm Preventative - Trifexis

2 Flea Meds
   A) Revolution - This medicine is applied to the skin, Kills fleas fast, Bath resistant after 24 hours, lasts 30 days, very safe. In Cats, Revolution is especially effective because it kills Hookworms, Whipworms, Roundworms, Heartworms and Ear Mites.  The only problem I've noticed with Revolution is a small patch of hair loss at the site of administration in some animals. This can be avoided by applying it in several different spots as you use each dose.

   B)  Comfortis - This is an oral flea pill that really works! Comfortis is only for Dogs. It acts very quickly, often within 30 minutes and kills fleas for the whole month. It is probably the most effective flea medication on the market today. It is also very safe. Comfortis must be given with a meal. Vomiting is the only side effect that has been reported to me so far.  I have found that about 2% - 5% of dogs cannot tolerate Comfortis and are better with Revolution. However for the other 95% of dogs, it is a great product.  For more information follow this link

3 Heartworm Preventatives - Veterinarians use the term Heartworm Preventative to refer to this group of medications but they do a lot more than just that. The best of these medications also control the extremely common intestinal worms as well.

  a) Four species of intestinal worms are common in Western North Carolina. These are the Hookworms, Roundworms, Whipworms and Tapeworms. Of these the least dangerous is the Tapeworm.

  b) Sentinel Spectrum and Heartgard are the most popular and effective heartworm preventatives on the market. Both are safe and effective. Both control Hookworms and Roundworm in addition to Heartworms. I choose the Sentinel Spectrum  because it controls two extra species of intestinal worm that are common in our area, the Whipworm and Tapeworms.
