Many medications can cause side effects. A side effect is an unwanted response to a medication when it is taken in normal doses. Side effects can be mild or severe, temporary or permanent. The side effects listed below are not experienced by everyone who takes this medication. If you are concerned about side effects, discuss the risks and benefits of this medication with your doctor.

The following side effects have been reported by at least 1% of people taking this medication. Many of these side effects can be managed, and some may go away on their own over time.

Contact your doctor if you experience these side effects and they are severe or bothersome. Your pharmacist may be able to advise you on managing side effects.

  • abdominal cramps
  • diarrhea
  • headache
  • heat intolerance

Are there any other precautions or warnings for Thyroid?

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 this medication.

Diabetes: Desiccated thyroid may cause blood sugar to increase. Therefore, high blood sugar may occur, glucose tolerance may change, and diabetes may worsen. People with diabetes should monitor their blood sugar closely and talk to their doctor about any abnormalities.

Hair loss in children: Some children may lose some of their hair in the first few months of treatment with thyroid hormone. This is usually a temporary effect and the hair normally grows back over time.

Heart disease: Starting desiccated thyroid may cause the heart to work harder than it has been used to. For this reason, people with angina or other heart disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Pregnancy: Supplemental thyroid hormone is safe to use during pregnancy.

Breast-feeding: Minimal amounts of thyroid hormone pass into breast milk. Inform your doctor if you are breast-feeding or intending to breast-feed while using this medication.

What other drugs could interact with Thyroid?

There may be an interaction between desiccated thyroid and any of the following:

  • amphetamines
  • antacids that contain aluminum or calcium
  • birth control pills
  • calcium polystyrene
  • calcium supplements (e.g., calcium carbonate, calcium citrate)
  • carbamazepine
  • cholestyramine
  • colestipol
  • diabetes medications (e.g., insulin, glyburide, metformin)

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 this medication. 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.
