Hyperthyroidism is a condition that occurs when the thyroid gland produces too much thyroid hormone. Tapazole inhibits the production of thyroid hormones.
Blood tests must be done to check for proper dosage. Do not use in pregnant or nursing pets. Do not give your pet a live vaccine while giving Tapazole. Contact your veterinarian immediately if your pet develops signs of an infection.

What is the most important thing I should know about Tapazole?
Tapazole prevents the thyroid gland from producing too much thyroid hormone. Tapazole is used to treat overactive thyroid (hyperthyroidism). It is also used before thyroid surgery or radioactive iodine treatment. Tapazole may also be used for purposes other than those listed in this guide. Tapazole is a prescription medication not FDA approved for veterinary use; however, it is a commonly accepted practice for veterinarians to use this medication in cats. Tapazole is available as a 5 mg scored tablet. Do not give Tapazole to pregnant or nursing pets. Tapazole can increase the risk of bleeding. Tapazole can lower the blood cells that help fight infections. Your veterinarian will need to give blood tests on a regular basis to be sure these blood cells do not get too low. Do not give the pet a "live" vaccine while the pet is taking Tapazole. Tapazole is need for the life of your pet. If the medication is stopped, the symptoms will reappear.
What should I discuss with my veterinarian before giving Tapazole to my pet?
Tell your veterinarian if your pet has an allergy to Tapazole or if your pet has liver disease, a blood cell disorder, or a weak immune system. Tell your veterinarian if the pet is pregnant or nursing. Inform your veterinarian of any other medications, including vitamins and supplements your pet may be taking while receiving Tapazole.
How should Tapazole be given?
Give this medication exactly as directed by your veterinarian. The usual initial dose for cats is 5mg every 8 to 12 hours. Do not give in larger amount, or give it for longer than recommended by your veterinarian. Follow the directions on the prescription label. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Tapazole can be given with or without food. Allow plenty of water for the pet to drink.
What are the potential side effects of Tapazole?
If any of the following serious side effects occur, stop giving Tapazole and seek emergency veterinary medical attention; an allergic reaction (difficulty breathing; swelling of the lips; tongue or face; hives). Stop giving Tapazole and contact your veterinarian at once if your pet develops any of these serious side effects; fever, chills, body aches; easy bruising or bleeding, unusual weakness; blood in the urine or stools; severe blistering, peeling, and skin rash; nausea, low fever, loss of appetite, dark urine, jaundice. Other less serious side effects may occur. Continue giving Tapazole and talk to your veterinarian if your pet experiences headache, drowsiness, dizziness; mild nausea, or vomiting; itching; muscle, joint, or nerve pain; swelling; hair loss. Other side effects may also occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to your pet.
What happens if I miss giving a dose of Tapazole?
Give the missed dose as soon as you remember during the same day. However, if you don't remember until the next day, skip the dose you missed and give only the next regularly scheduled dose. Do not give a double dose of the medication.
What happens if I overdose my pet on Tapazole?
Seek emergency veterinary medical treatment. Symptoms of Tapazole overdose may include nausea, vomiting, upset stomach, joint pain, headache, fever, itching, swelling, and easy bruising or bleeding.
What should I avoid while giving Tapazole to my pet?
Do not give the pet a "live" vaccine while the pet is taking Tapazole. Contact your veterinarian at once if your pet develops signs of an infection.
What other drugs will affect Tapazole?
Tell your veterinarian if your pet is taking theophylline (Theo-Dur), warfarin (Coumadin), digoxin (Lanoxin), a beta blocker such as atenolol (Tenormin), metoprolol (Lopressor), or propranolol (Inderal). Drugs other than those listed may also interact with Tapazole. Talk to your veterinarian or pharmacist before giving any prescription or over the counter medicines.

I didn't think my 16 yo cat had a problem at all, just went to the vet for routine stuff. The vet said he was mildly hyperthyroid and that could get to be a problem and put him on the drug at 2.5 mg per day. After one month, his liver tests showed complete failure. He is still alive due to a lot of injections but he won't eat at all, and he's too old to anesthetize and tube feed. So now my cat, who appeared completely healthy and active, will probably be put to sleep this week. Unless a cat is severely hyperthyroid, I would not use this drug.

My 19 year old cat Abby has been on Tapazole 5mg for several years now and doing well. When I get up in the morning, she is there waiting for me to give her the pill in the pill pocket and won't eat until she gets it. :) She takes two a day. But unfortunately, the price has more than doubled and I am now looking to see if I can purchase this medication at a lower cost or possibly try the generic. I didn't have any choice. I see other costs listed here and it is much lower. Have to talk to Pet Meds and find out why. Not happy. I have three other cats and it is expensive.

Tapazole great product
My 16 year old cat lady was diagnosed with Hyperthyroidism about one month ago. Her T4 and Free T4 were high. We started her on 2.5mg for two weeks then checked her blood results. Her blood results have improved in that they are starting to go down. She will be on 5mg for the next month and then we are going to take her blood again to see if the higher dose will bring down T4 and Free T4 down to normal and keep it that way. Did not want to start her on too high a dose as it can cause liver and kidney problems. She is doing fine on this medication and actually has gained some weight back. She is much more relaxed and not so nervous. Also Tapazole is not generic Methimazole is. Will try her on Methimazole later on if cost is prohibited. Also I put the tablet into her moist food that i give once a day and it goes right down and no stress to her. Also you can't beat the prices of 1-800-pet meds. The vet is a lot more expensive but I do love my vets-they are very caring and truly want to do what is best for my pet.

My 16 year old female cat lost half her body weight (went from 14 pounds to under 7) due to hyperthyroidism. She went on Tapazole, which literally saved her life! She has a ravanous appetite, but has regained a lot of the weight and is radically improved. We no longer feel her bony spine when we pet her back. This medication saved her life! She's been on the brand name, but am going to try to switch her to the generic due to the high cost. 5 stars for effectiveness and overall rating, and 1 star for taste. We have to force feed her the pill twice daily.

Cat turned into Zombie...
Our cat had too many side effects with this medication....scratching around face and ears, vomiting.... she looked like a zombie! We switched to Carbimazole which is converted to methimazole in the body and is less likely to cause side effects. We were able to get it at our local compounding pharmacy. Her weight is steady and no side effects!
