Sentinel & Liver failure ?
Sadly I am going to lose my second dog to liver failure. While the
circumstances and symptoms are different, I am worried that there is a link with respect to food, environment or medicine. One thing that both dogs have had in common is that they have been on the monthly Sentinel program to protect against worms and fleas. The medication has been given according to the prescriptions once a month and never showed any side-effects. Is anybody aware of any issues with respect to Sentinel? My dogs were/are large dogs (Cross Kelpie/German Shepard and Cross Labrador/German Shepard). My current dog (XLab) that has just been diagnosed with liver failure is not even 7 years old, has never been sick before, so losing another dog to liver failure comes as a shock to me. Since I have two other dogs that I would like to protect as much as possible, any advice or info is greatly appreciated. |

I for one do not treat for fleas unless they show up. I feel the less
toxins in the dogs body the better and anyway you look at it, it is a toxin. The only preventative I use on my dogs year round is a monthly interceptor for heartworms and only because heartworm can be fatal to a dog. Barney is my flea barometer and the first bite of a flea he's digging away. I'm lucky with these two since in the last 4 years I've only had to do two treatments for fleas and because I caught them early it amounted to only 1 dose of Frontline Plus on each dog and the three cats and that was the end of the fleas.

Some of them only affect the liver. Any tests run for canine hepatitis - apprently liver biopsy is necesary for definitive diagnosis. Do you have any mushrooms in your yard that your dogs may eat? Do you leave your dogs unattended in the yard and have any loony neighbors? Do you give any other drugs on a regular basis? Is anybody aware of any issues with respect to Sentinel? ..........not that I could find. There are neurological effects if overdosed and some dogs react if given the normal dosage. You can read the original research on milbemycin oxime-lufenuron at the Center for Vet Med (USDA) by searching on NADA 141-084, which is the New Animal Drug Approval number. You can either just enter that in the search box on this page: http://www.fda.gov/cvm/default.html Or go to the Freedom of Information section and search. To look at adverse reactions search under Adverse Drug Reactions. Both ivermectin (in Heartgard) and milbemycin (in Sentinel) are called macrocylic lactones. From the online Merck Vet Manual: http://www.merckvetmanual.com/mvm/in.../bc/191414.htm The macrocyclic lactones are mostly excreted in the feces, the remainder in the urine. Minimal residues are present in the muscle and kidneys, and highest concentrations are detected in the liver and fat tissue................Mammals are generally not adversely affected by macrocyclic lactones. Mammalian safety appears to depend on P-glycoprotein activity in the blood-brain barrier. P-glycoproteins act to pump out macrocyclic lactones from CNS cells, and animals with defective P-glycoprotein levels in the blood-brain barrier are susceptible to macrocyclic lactone toxicity. There have been a number of cases of CNS depression in purebred and crossbred Collies at higher than recommended dosages. Dr. Mike on liver disease and heartworm preventatives: http://www.vetinfo4dogs.com/dliver.html We have used these medications in a number of dogs with liver disease, since we live in a heartworm endemic area and so far, we have not been able to detect problems with either ivermectin (Heartgard 30 Rx) or milbemycin (Interceptor or Sentinel Rx). These drugs do cycle through the liver however. I hope you can figure out what is going on. This is very sad. buglady take out the dog before replying |

Has your vet discussed the possibility of using milk thistle for rejuvenating
the liver? |

ch as possible, any advice or info is greatly appreciated.
Thanks guys for your posts, much appreciated. I have followed some of the links and will read up on this more. I have talked once again with my vet regarding Sentinel and milk thistle. As for Sentinel he has not heard anything bad about side effects like we exerienced, in fact thinks that the constituent ingredient is reportedly less of a problem than some other medications. Still, I think I will look for an alternative and reduce the medication to the essential only instead of the cover everyting at once pill. I also asked re milk thistle, my vet did not have any info on that but I will try. Hopefully it may help though given the prognosis, it might be too late. Thanks again everybody. |

Buglady,
I followed your reference and searched the google groups for info on the dosage but I am a bit confused. Sofar I have found milk thistle in pharmacies only in form of capsules.The product I bought says extract equivalent to dry fruit 7g (7000mg) and standardized to contain flavanolignans 84mg. The recommended dosage for adults is 1 tablet three times daily. One of the articles mentioned recommends as a typical adult dosage for silymarin to be 240-900mg/day. Does that relate to the standardized 84g/tablet as above? I have not found any liquid product - any brandnames that I can search for. Not sure whether it would be available in Australia, but I could try. Kind Regards Tom On Tue, 24 Aug 2004 17:27:37 GMT, "buglady" wrote: http://www.thorne.com/altmedrev/fulltext/liver3-6.html |

... Sofar I have found milk thistle in pharmacies only in form of capsules. ..........Health food stores usually have liquid extracts. Don't know what the situation is in Oz though. When dealing with an ongoing liver problem, liquids are usually used because they are absorbed at a higher rate. Is this what you bought? http://www.blackmores.com.au/product...at=107&prod=69 The product I bought says extract equivalent to dry fruit 7g (7000mg) and standardized to contain flavanolignans 84mg. The recommended dosage for adults is 1 tablet three times daily. Quote from Herbs for Pets about standardization of herbs: A standardized extract is more of a plant drug than an herbal medicine......For example, in nature, milk thistle seeds contain anywhere from 2% to 6% silymarin, the most medicinally active component of the plant. In cases of severe liver damage or toxicity,a much higher percentage of silymarin may be needed to quickly bring about a therapeutic effect. A milk thistle extract that has been standardized to as much as 80% silymarin can be used in such cases. Silymarin is sort of a catchall term. See below http://www.ironmagazine.com/review46.html .......Quite frankly I don't like the kind of labeling on the product you bought. It only adds to the confusion. And I wonder about not using the term silymarin on the label. Just go with the 84 mg and figure dose from there. vet recommendations for use: Jean Hofve, DVM http://www.canine-epilepsy-guardian-...lk_thistle.htm Veterinary Botanical Medical Association - Susan Wynn, DVM http://www.vbma.org/herbs/milkthistle8-02.html Russell Swift, DVM http://siriusdog.com/articles/milk-t...m-marianum.htm Gulf Coast VEterinary Oncology staff: http://www.zzcat.com/TumorTidbits/Mi...-Silymarin.txt Antech Diagnostics (a veterinary laboratory service) http://www.antechdiagnostics.com/cli.../2000/7-00.htm One of the articles mentioned recommends as a typical adult dosage for silymarin to be 240-900mg/day. Does that relate to the standardized 84g/tablet as above? .......I think most milk thistle products are standardized. Mary-Wulff Tilford & Gregory Tilford (Herbs for Pets) recommend that powdered extracts should be standardized to contain 60- 80% silymarin http://medherb.com/SAMPLE.HTM Milk thistle seed extracts, usually standardized to 70% silymarin content, are commonly used in conventional medicine in Europe, where it has been officially available since 1969. .......Now what % your tablets are standardized to is the question! If it's the company I mentioned above, why don't you write them? Or go to a health food store and get something else and return these to the drug store, which is not a place I usually buy supplements. As for figuring dosages for dogs - all human supplements are generally forumlated for a 150 pound adult. Use percentages of that depending on weight for your dog. The Tilfords recommend dosing dogs and cats with smaller more frequent doses during the day. HTH buglady take out the dog before replying |
