Why is my dog so sleepy on prednisone and cephalexin for allergies?

Hi, thank you for using Petco Pet Education Center, formerly Petcoach. I'm sorry Titan is not himself. You didn't say why Titan is on medications, it may be that his sleepiness is due to his primary problem. Sedation is not typically a side effect of either cephalexin or prednisone. Be sure that he hasn't gotten into any other medications or toxins. If he is able to be awakened and has a normal response to calling his name, eating, drinking and normal urination and defecation he may just be tired out. If he is not responsive or sluggish to respond, then I recommend an emergency vet tonight to rule out an serious problems. I hope Titan is back to normal soon.

Thank you for using Petco Pet Education Center, formerly Petcoach! Cephalexin is a commonly used antibiotic and has minimal side effects. Most of the side effects have to do with intestinal signs - mild nausea, diarrhea, or decreased appetite - all of these can be causing Chicharito to be a little bit less active. In rare cases, cephalexin can cause kidney damage, but this is in dogs who already have kidney disease. I hope this helps and am happy to answer any other questions you may have regarding your pets medications!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Lua. Yes, a general loss of energy is a common side effect of prednisone. This should pass after she goes off the steroid. It's good that she is eating and drinking, and I would continue to monitor her. I hope this helps!

Prednisone can absolutely cause behavior changes and mood alterations. The side effects are usually at their greatest during the first two to four week of therapy as the body grows accustomed to glucocorticoid drugs. The metronidazole is not likely a cause of any side effects you are currently seeing. If you are consulting with a oncologist regarding Pepe's case, do not hesitate to contact them with any questions involving his therapy. These cases can often be complex and require a lot of special attention to drug interactions. Anyway, if you require further consultation please let me know. Hope this makes sense.

Usually cephalexin is well tolerated by dogs, but it can cause nausea, vomiting, and diarrhea. This can be alleviated by giving Molly her medication with food, but to be safe, I'd give your vet a call to let them know she is having these side effects. They made decide to have you stop giving it, and may want to try a different medication. I'd give your vet a call now. Best of luck.

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!

Those are definitely the side-effects; increased appetite and thirst, change in behavior, panting more and weight gain. For more information about the side-effects, I recommend you read the article at the link below. https://vcahospitals.com/know-your-pet/steroid-treatment-long-term-effects-in-dogs I assume the nose condition you described was diagnosed as an autoimmune disease (i.e. lupus, pemphigus). The mainstay treatment for this condition is prednisone. However, there are other possible treatments, so it's worth scheduling a recheck appointment with your veterinarian. It's quite common for some owners not to like the side-effects of steroids, so they should understand and be able to suggest other options. I hope that helps and Kenzie gets better soon.
