Why is my dog so sleepy on prednisone and cephalexin for allergies?
Lethargy and altered behavior are pretty typical side effects of prednisone. Along with this you may also see things like increased drinking, urinating, and eating. Long term side effects can include liver damage and commencement of certain diseases of the endocrine system. Cephalexin is an antibiotic that has the main side effect of gastrointestinal upset. If you decide that you do not think the prednisone is worth using due to the side effects, do not discontinue it abruptly. It has to be tapered down slowly as to prevent any harm to Kaiser. Hope this helps.

Cephalexin vs. Simplicef: Which antibiotic is right for my pet?
Cephalexin and Simplicef are both cephalosporins, so they are the same group of antibiotics, but cephalexin is the generic name for a 1st generation cephalosporin and Simplicef is a trade name for Cefpodoxime which is a 3rd generation cephalosporin (so it is a newer drug) and works better in some circumstances. Here is more information on both drugs. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=538 https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=2038 I hope that was helpful!

Vet Q & A
My 16lb dog accidentally ate a 500mg cephalexin pill. Is she okay?
Hi there and thank you for using Pet Coach to address your concern. At the high end of the dose of 60mg/kg for systemic infections, it would be approximately 436mg every 8 hours for that dose for a 16lb dog. A 500mg capsule will not likely cause any life threatening problems. You may see vomiting and diarrhea but this should resolve on its own. If you start to see neurological symptoms such as seizures or a wobbly gait, I would have a veterinarian examine KC. I hope this helps! Please let me know if you have any other questions or concerns and I would be happy to help further.

Vet Q & A
My dog is on prednisone & cephalexin. Is his panting & stool normal?
Thanks for using Petco Pet Education Center, formerly Petcoach! Prednisone is a steroid. Steroids cause pets to eat more, drink more, urinate more, and pant. The increased stool could be if he is eating more but antibiotics, like cephalexin, can cause loose stools. I suspect the signs you are seeing is because of the medications. If you notice any vomiting or diarrhea please let the veterinarian that prescribed the medications know. Kisses to Cooper!

My dog has a hot spot. Should I give her cephalexin or see a vet?
Unfortunately, by law it is illegal for the experts at PetCoach to recommend giving a prescription drug without seeing the animal in person first. That's because doing so requires a veterinary client patient relationship which cannot be achieved via an internet forum. In addition, the experts cannot say for certain if a specific drug is safe for Cleo. Typically antibiotics are not given to treat hot spots unless there is a secondary infection, treating them requires a steroid cream that is available by prescription only from the vet. I would take Cleo into the vet first thing Monday to have the hot spot treatment. In the meantime, you can give her an Epsom salt bath to see if that gives her temporary relief, and put an Ecollar on her to keep her from licking at it and making it worse. You can get an Ecollar from a pet store or make one at home: http://dogsaholic.com/care/homemade-dog-cone.html
