The degree and extent of bone loss is most closely related to cumulative corticosteroid dose. The most rapid rate of bone loss is during the first 3 to 6 months of therapy. All patients starting gluocorticoids at any dose with an anticipated duration of at least 3 months or longer should start calcium 1200-1500mg/day and vitamin D 800-1000 international units/day supplementation. These patients should also be counseled on smoking cessation and weight-bearing activities. Additionally, they should be assessed for fall risk, baseline height, and history of fragility fractures.
Pregnant rats administered piroxicam at 2, 5, or 10 mg/kg/day during the period of organogenesis (Gestation Days 6 to 15) demonstrated increased post-implantation losses with 5 and 10 mg/kg/day of piroxicam (equivalent to 2 and 5 times the maximum recommended human dose [MRHD], of 20 mg respectively, based on a mg/m body surface area [BSA]). There were no drug-related developmental abnormalities noted in offspring. Gastrointestinal tract toxicity was increased in pregnant rats in the last trimester of pregnancy compared to non-pregnant rats or rats in earlier trimesters of pregnancy. Pregnant rabbits administered piroxicam at 2, 5, or 10 mg/kg/day during the period of organogenesis (Gestation Days 7 to 18) demonstrated no drug-related developmental abnormalities in offspring (up to 10 times the MRHD based on a mg/m 2 BSA).
I have a almost three year old Australian Sheppard/Chow Chow Mix. He has taken Comfortis and Heartgard since I rescued him last November. I decided this month to switch to Trifexis. He received his first dose at breakfast on the 15th of July. I put the pill in with the rest of his food and it is eaten along with the rest of his food during that feeding. I have noticed slighlty more itching but nothing extreme and I have noticed, last night especially, that during his brushing there was quite a lot of hair consumed in the brush. It is shedding season though, so I’m unsure that this is a reaction to the medication. I will continue to monitor my dog and he also has three days a week spent with his personal trainer and some other dogs that do day care as well. Good socializing and excellent time spent with a trainer. As far as Trifexis is concerned, just like any other medication you have to monitor your dog and observe things that are unusual for your dog. Make sure he/she is not getting into other things that could cause bad behavior or mischief that could lead to what appears as adverse reactions to the medicine.
