I need some help. Mare is severely allergic to oxytocin. Hives and swelling of face.
A few days ago at 252 she developed a bag and started the appropriate medicines. After 10 cc of regumate she is getting bad hives. ( one dose). I am guessing it is the regumate. What to do????
4-7-13 Day 321 No change

Ultrasound looked good, would have to order the injectable on Monday, is that what you would do, my vet is very worried even though all looked good except for a bag, what do I do if the hives get worse. Dex or let her suffer?
I personally would skip the regumate altogether if the ultrasound looks ok. You would have to monitor her closely and be ready to add it in if necessary. I would do one week per month of SMZs at minimum, possibly keeping her on them until closer to her due date. Lots of decisions to make, jingles.
I went to a lecture at the New Bolton Center on The Critically Ill Foal, given by Dr. Palmer. Basically, he said that most issues with newborn foals are a result of placentitis in the mare. He also said that regumate acts more as an anti inflammatory for placentitis, not just as supplemental progesterone to keep the mare pregnant. I would try SMZ's and banamine if it were my mare.

There is no reason why the mare cannot be given Dexamethasone if indicated.
Unlike other species, Dexamethasone has not been shown to induce abortion in the mare (dependent upon dose) and is in fact recommended to accelerate fetal development in later pregnancies involving placentitis and potential early delivery.
SMZ! Can't hurt and we always do 5 days' worth minimum if we suspect anything. That's prime time for placentitis (ours that had cases all had sudden udder development at day 250-275). If you do the SMZ's and the udder reduces quickly, chances are high you're dealing with placentitis.
If were my mare I would start immediately but I'm not a vet... however, we've lost a foal due to not understanding the signs and taking action so it's better safe than sorry for us from now on. She should not be develping an udder at 250 days no matter what... definite sign of something. In both of ours you could not see any real issue on ultrasound, either. With one mare we put her back on SMZ when udder came back after the 5 days to start (day 282 it cropped up for her), and she stayed on it after day 305 until she delivered at 322. She was milk testing "ready to go" on day 314.
