Tapazole How to Take

Tapazole (Methimazole) belongs to the class of medications called antithyroid medications. It is used to treat Hyperthyroidism (overactive Thyroid gland). It prevents the thyroid gland from over-producing thyroid hormone, but does not interfere with the actions of thyroid hormone. It may take weeks to months before Tapazole (Methimazole) has its full effect on the symptoms of overactive thyroid (e.g., palpitations, sweating). During this time period, other medications may be used to control these symptoms.

Tapazole (Methimazole) may be available under multiple brand names and/or in several different forms. Any specific brand name of Tapazole (Methimazole) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Tapazole (Methimazole) may not be used for all of the conditions discussed here.

Your doctor may have suggested Tapazole (Methimazole) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Tapazole (Methimazole), speak to your doctor. Do not stop taking Tapazole (Methimazole) without consulting your doctor.

Do not give Tapazole (Methimazole) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Tapazole (Methimazole) if their doctor has not prescribed it.

Tapazole Precautions

There may be an interaction between Tapazole (Methimazole) and any of the following:

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

  • stop taking one of the medications,
  • change one of the medications to another,
  • change how you are taking one or both of the medications, or
  • leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Tapazole (Methimazole). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Tapazole Warnings

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Tapazole (Methimazole).

Bleeding:  Tapazole (Methimazole) may cause a reduced number of platelets in the blood, which can make it difficult to stop cuts from bleeding. If you notice any signs of bleeding, such as frequent nosebleeds, unexplained bruising, or black and tarry stools, notify your doctor as soon as possible. Your doctor will order routine blood tests to make sure potential problems are caught early.

Galactose intolerance/glucose malabsorption: Tapazole (Methimazole) medications are prepared with lactose. If you have lactose or galactose intolerance you should not take these medications.

Infection: Tapazole (Methimazole) can reduce the number of cells that fight infection in the body (white blood cells). Your doctor will likely want you to have laboratory tests done on a regular basis because in rare cases, Tapazole (Methimazole) can cause the levels of white blood cells to decrease. Low white blood cell levels can increase the risk of infection. If you have a sore throat, skin rash, fever, headache, or a general feeling of being unwell, tell your doctor immediately.

Pregnancy: Tapazole (Methimazole) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Tapazole (Methimazole), contact your doctor immediately.

Breast-feeding: Tapazole (Methimazole) passes into breast milk. If you are a breast-feeding mother and are taking Tapazole (Methimazole), it may affect your baby. Women using Tapazole (Methimazole) are advised to not breast-feed.
