My Siberian Huskey (age 5, 55lbs, male) has been on Prednisolone for 2 weeks for allergies. He has 3 more pills to take, but yesterday he started vomiting. 6 times in 15 hours. (Brown color)


He has been outside a lot also but there were only 2 puddles on the porch, and the rest were in the house. He has been drinking lots of water, and I just gave him some icecubes. I don’t have any pepto… I just read online that he could take that. This will make the 2nd day without any prednisolone. Should the vomiting subside now that he is off of it? I read that vomiting is a side effect of that medication!

Comments for Dog Vomiting – Caused By Medication

Hi Beth,
Sorry to hear that your Siberian Husky is not doing well. There is concern for vomiting that occurs while taking prednisolone. Cortisone type drugs will affect the liver and the adrenal glands, also causing side effects such as increased thirst, increased urination, and increased appetite. Long term cortisone will also suppress the immune system. Dogs that are prone to pancreatitis can be worse when on cortisone. It would be much healthier for your dog to start weaning him off of the prednisolone and to clear up his allergies by alternative treatments.

You did not mention if you were giving the Prednisolone one time daily, twice a day, or every other day. If he has not had any cortisone now for 2 days, then I would stop it completely. The cortisone will stay in his system for 2-4 more weeks. Do not give any Pepto Bismol.

At this point, continue the ice cubes for 12 hours. You can make up some ‘chicken broth’ ice cubes. If he continues vomiting, take him to a veterinarian for Sub Q, or intravenous fluids to prevent dehydration. If he is not vomiting after 12 hours on ice cubes, then offer fresh water, and also chicken or turkey broth or beef boullion.

If there is no vomiting after 24 hours on liquids, then you can start ‘bland food’ such a chicken or turkey baby food. Give him only 1/2 jar to start. Wait 2-3 hours. If he does not vomit, then give him the rest of the jar, and continue with 1/2-2/3 jar every 3 hours for one day.

The next day (if no vomiting), add 2-3 Tbsp of cooked rice with 1-2 jars of baby food. And feed him 5-6 small meals per day for 2-3 days.

At this point, you should seek the advice of a holistic veterinarian who can guide you along with the best dog food diet for him, and also provide some alternative treatments for his allergy. A good quality, natural, raw natural dog food diet may be the best thing for his skin and hair coat.

Nov 16, 2012Dexamethazone caused vomiting in my boxer
by: Mik

My 63 pound boxer mix just had a shot of dexamethazone yesterday for an allergic reaction to a plant ( hives and vomiting) and now she has been throwing up and having diarrhea for an hour and a half. I know how you feel. I’m wondering if this is a serious reaction. Can’t take her to her vet because it’s 4 am

Hi Mik,
Veterinary Emergency clinics are open 24 hours, or at least between the hours of 6PM-8AM, to cover the time that ‘regular’ veterinary hospitals are normally closed.

It sounds like the allergic reaction to a plant (hives and vomiting) may have progressed so that now she has been throwing up and having diarrhea. The dexamethasone may or may not be the problem.

Seeking the help of a holistic veterinarian would be optimal, so that the use of conventional drugs could be avoided.

Another resource for vets knowledgeable in homeopathy is AVH.org.
