Dog suddenly showing adverse reactions to Atopica (I think). Any suggestions as to what might be going on?

Thanks for reaching out. It can be really worrisome when our pets have unexpected reactions to medications like Atopica (Cyclosporine), which is often used to help manage allergies or skin conditions. Sometimes, dogs can experience side effects such as gastrointestinal upset, which might include vomiting or diarrhea, or even a decrease in appetite. Less common reactions could include lethargy or changes in behavior.



Firstly, ensure your dog is comfortable and has access to fresh water, especially if they're vomiting or have diarrhea. You might consider offering bland food such as boiled chicken and rice to help settle their stomach, but be sure to check if they’re willing to eat and drink normally.



Watch for signs that could indicate a more serious issue. If your dog continues to vomit, shows signs of dehydration, appears very lethargic, or if you notice any swelling or difficulty breathing, these could be a cause for more immediate concern.



It’s best to pause the medication temporarily until you've had a chance to discuss this with a vet to avoid further complications. I recommend booking a video consult with one of our vets on Dial A Vet so we can tailor advice specific to your dog’s situation and determine the best course of action together.
