My dog missed his hyperthyroidism medicine for 10 days. Is he okay?

Since it has been several hours, inducing vomiting will not help. Dogs take higher doses of thyroid medications than humans do, so it is likely that Roxy will be fine. He may develop some stomach upset. Monitor for rapid heart rate, panting and restlessness or hyperactivity. These are symptoms that should be addressed by your veterinarian or at the nearest veterinary ER. You can also contact the Pet Poison Helpline ( https://www.petpoisonhelpline.com/ ). They are staffed by toxicologists who have more detailed information. There is a fee for the call. https://www.petpoisonhelpline.com/poison/thyroid-medications/

If it has been two days with no issues Casper will likely be ok. I recommend monitoring him for decreased appetite, vomiting, diarrhea, dark stools and/or pain/pale gums for one week to ten days past the possible ingestion time. If you see any of those signs he needs to be seen by his veterinarian.

It is unlikely that this will cause any damage or side effects. T4 hormone will be temporarily suppressed, without any noticeable side effects.

The only way to know if this is related is to have the thyroid level checked again. I recommend to call your veterinarian and let them know what you are seeing. They will advise on how much medication to give and when to test. The only way to know if Glanni truly has thyroid disease is to stop all medication for at least 2 weeks. Then test a thyroid panel that includes the Total T4, the Free T4 by equilibrium dialysis and the Thyroid stimulating Hormone. This will give you a complete and accurate idea of his thyroid function. I do not advise to make any changes to the medication with out first speaking with your regular veterinarian. Also keep in mind that the behavior could be coincidental and related to something else entirely. Best of luck.

Overdosage of any thyroid drug may produce the signs and symptoms of thyrotoxicosis including, but not limited to: polydipsia, polyuria, polyphagia, reduced heat tolerance and hyperactivity or personality change. if she is experiencing any of those- take her to your vet, if not she should be fine.

You are very welcome. Yes, once you find the right dosage, this medication will be life long because his thyroid will not be able to produce the correct amount of hormone. If you stop the medication he will not have enough thyroid hormone. Pets who lack this hormone struggle with not feeling well, weight gain, skin infections and a heavy thirst. They definitely don’t feel like themselves so it’s important to continue the medication. Please feel free to post any additional questions.

It may take a little longer than two weeks to get his thyroid levels up. It looks like Butter is still dealing with skin inflammation and possible infection. Usually dogs will come back about two weeks after starting thyroid medication to check the blood levels. I advise to schedule that appointment and have them check the skin as well. In the mean time, you can wash the affected areas once daily with hand soap and rinse well. Make sure he is not licking the lesions as he will make it worse. An elizabethan collar will help prevent this. If he continues to have skin issues and his thyroid levels are good, it is possible that underlying allergies could also be affecting him. I hope this is helpful. Please feel free to post any additional questions.
