The MDR1 mutation can create dangerous milbemycin oxime sensitivity. A healthy P-glycoprotein system is what allows milbemycin oxime to be safe for mammals even in very high doses. The MDR1 mutation (recently renamed the ABCB-1 mutation) concerns the function of something called the "P-glycoprotein." In normal patients, the P-glycoprotein is involved in keeping drugs out of certain tissues and is important in keeping milbemycin oxime out of the patient's nervous system. Breeds that are most commonly involved are collie-related breeds but other breeds can be involved. There are no meaningful drug interactions except in dogs with the MDR1 mutation. Inform your veterinarian that a dose was skipped as this may matter in the parasite protocol depending on what the target parasite is. If a dose is accidentally skipped, give it when it is remembered. Milbemycin oxime may be given with our without food. In cats, a milbemycin oxime ear drop is commercially available. SARCOPTIC MANGE MITES: Sarcoptic mange mites are sensitive to milbemycin oxime but a special off-label protocol is needed.ĮAR MITES: Ear mites are sensitive to milbemycin oxime given orally but a special protocol is likely necessary. Oral use of milbemycin oxime for parasites other than these is considered "off label" and higher doses may be involved.ĭEMODECTIC MANGE MITES: Canine demodex mites are sensitive to milbemycin oxime but it medication must be given daily. Kittens should be at least 6 weeks of age and one and a half pounds of weight. Puppies should be at least 2 lbs by weight and at least 4 weeks of age. HEARTWORM, HOOKWORM, ROUNDWORMS AND, FOR DOGS, WHIPWORMS: A monthly tablet for dogs and cats. How this medication is used depends on the target parasite. It has activity against many parasites and it has been combined with other anti-parasite medications to create even broader spectrum parasite protection. As of this writing, milbemycin oxime is also available as an ear drop for cats to be used against ear mites. Milbemycin oxime became commercially available shortly after with the added benefit of covering not only hookworms, heartworm, and roundworms, but also whipworms. It was an amazing development in pet care. When ivermectin became commercially available for dogs, heartworm (as well as hookworm and roundworm infection) could be prevented by a monthly chewable, as is commonly done today. Skipping even one dose would leave a dog vulnerable to a terrible infection. It is hard to imagine a time when heartworm prevention for dogs was handled with daily pills. It is effective against both flea and hydatid tapeworm.BRAND NAME: INTERCEPTOR, CORAXIS, MILBEGUARD, MILBEMITEĪLSO COMBINED WITH OTHER ANTI-PARASITE INGREDIENTS IN: TRIFEXIS, SENTINEL, INTERCEPTOR PLUS, SENTINEL SPECTRUM, MILBEMAX Praziquantel causes muscle spasm in tapeworm, which are then attacked by enzymes and disintegrate (minimum dose rate: 5mg/kg). Milbemycin oxime interferes with nerve transmission in invertebrates, which helps protect against heartworm, roundworm, hookworm and whipworm (minimum dose rate: 0.5mg/kg). Interceptor™ Spectrum Tasty Chews active ingredients are milbemycin oxime and praziquantel. Studies have confirmed safety at up to 10 times the recommended dose. To avoid this, dogs should be tested for adult heartworm and treated if necessary, before starting Interceptor™ Spectrum Tasty Chews. If an animal with adult heartworm infection (and therefore circulating microfilariae) is given Interceptor™ Spectrum Tasty Chews, a transient shock-like reaction can occur. Interceptor™ Spectrum Tasty Chews can be safely used in puppies from 2 weeks of age, breeding males and females, pregnant and lactating females, and in Collies sensitive to ivermectin.
