Therefore, thyroid desiccated should be taken on a consistent schedule with regard to time of day and relation to meals to avoid large fluctuations in blood levels, which may alter its effects.

In addition, absorption of thyroid desiccated may be decreased and/or delayed by foods such as:

  • soybean flour
  • cotton seed meal
  • walnuts
  • dietary fiber
  • calcium
  • calcium fortified juices
  • grapefruit or grapefruit juice

These foods should be avoided within several hours of dosing if possible.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate:

Food/Lifestyle semaglutide

Applies to: semaglutide

Food may affect the absorption of semaglutide when taken orally.

It is recommended that oral semaglutide be taken 30 minutes before first food, beverage, or other oral medications of the day with no more than 4 ounces of plain water.

You may experience more side effects including nausea, vomiting, and diarrhea if you fast longer than 30 minutes after the semaglutide dose.

Talk to a healthcare provider if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate:

multivitamins with minerals thyroid desiccated

Applies to: thyroid desiccated

You should separate the administration of thyroid desiccated and multivitamins with minerals by at least 4 hours.

If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Disease interactions

14 potential interactionsApplies to: 14 conditions, including High Blood Pressure, Seizures, Diarrhea, Gastroparesis, and Hyperthyroidism.

Adrenal Insufficiency

Major:

thyroid desiccated

Thyroid desiccated has a major potential interaction with Adrenal Insufficiency.

The use of thyroid hormones is contraindicated in patients with uncorrected adrenal insufficiency. Thyroid hormones increase tissue demand for adrenocortical hormones and may precipitate acute adrenal crisis. In patients with controlled adrenal insufficiency or other endocrine disorders, therapy for these concomitant disorders may need to be adjusted following thyroid replacement, since hypothyroidism often obscure or diminish the signs and symptoms of these conditions. Clinical monitoring of thyroid and adrenal function as well as any other appropriate endocrine function is recommended during thyroid hormone therapy.

Dehydration

Moderate:

semaglutide

Semaglutide has a moderate potential interaction with Dehydration.

There have been postmarketing reports of acute kidney injury (sometimes requiring hemodialysis) in patients treated with semaglutide. The majority of events occurred in patients with gastrointestinal adverse reactions leading to dehydration (e.g., nausea, vomiting, diarrhea); therefore, semaglutide is not recommended in patients with severe gastroparesis. It is recommended to monitor renal function in patients reporting adverse reactions to semaglutide that may lead to volume depletion, especially when initiating or escalating doses of semaglutide.

Diabetes Insipidus

Moderate:

thyroid desiccated

Thyroid desiccated has a moderate potential interaction with Diabetes Insipidus.

Since hypothyroidism often obscure or diminish the signs and symptoms of endocrine disorders such as diabetes mellitus or diabetes insipidus, thyroid replacement therapy may aggravate the intensity of symptoms associated with these conditions. Patients with endocrine disorders should be monitored more closely during thyroid hormone therapy, and their medication regimen adjusted accordingly. If thyroid medication is later discontinued, a downward readjustment of insulin or oral hypoglycemic agent may be necessary in patients with diabetes mellitus to avoid hypoglycemia.

Diabetes Mellitus

Moderate:

thyroid desiccated

Thyroid desiccated has a moderate potential interaction with Diabetes Mellitus.

Since hypothyroidism often obscure or diminish the signs and symptoms of endocrine disorders such as diabetes mellitus or diabetes insipidus, thyroid replacement therapy may aggravate the intensity of symptoms associated with these conditions. Patients with endocrine disorders should be monitored more closely during thyroid hormone therapy, and their medication regimen adjusted accordingly. If thyroid medication is later discontinued, a downward readjustment of insulin or oral hypoglycemic agent may be necessary in patients with diabetes mellitus to avoid hypoglycemia.

Diabetic Retinopathy

Moderate:

semaglutide

Semaglutide has a moderate potential interaction with Diabetic Retinopathy.

Patients with history of diabetic retinopathy should be monitored for progression of diabetic retinopathy during treatment with semaglutide. Rapid improvement in glucose control has been associated with a temporary worsening of diabetic retinopathy.

Diarrhea

Moderate:

semaglutide

Semaglutide has a moderate potential interaction with Diarrhea.

There have been postmarketing reports of acute kidney injury (sometimes requiring hemodialysis) in patients treated with semaglutide. The majority of events occurred in patients with gastrointestinal adverse reactions leading to dehydration (e.g., nausea, vomiting, diarrhea); therefore, semaglutide is not recommended in patients with severe gastroparesis. It is recommended to monitor renal function in patients reporting adverse reactions to semaglutide that may lead to volume depletion, especially when initiating or escalating doses of semaglutide.

Gastroparesis

Moderate:

semaglutide

Semaglutide has a moderate potential interaction with Gastroparesis.

There have been postmarketing reports of acute kidney injury (sometimes requiring hemodialysis) in patients treated with semaglutide. The majority of events occurred in patients with gastrointestinal adverse reactions leading to dehydration (e.g., nausea, vomiting, diarrhea); therefore, semaglutide is not recommended in patients with severe gastroparesis. It is recommended to monitor renal function in patients reporting adverse reactions to semaglutide that may lead to volume depletion, especially when initiating or escalating doses of semaglutide.

Heart Disease

Major:

thyroid desiccated

Thyroid desiccated has a major potential interaction with Heart Disease.

Thyroid hormones cause increases in myocardial contractility and heart rate as a result of increased metabolic demands and oxygen consumption. Therapy with thyroid hormones should be administered cautiously and initiated at reduced dosages in patients with cardiovascular disorders such as angina, coronary artery disease, and hypertension. Clinical monitoring of cardiovascular function is recommended. If chest pain or exacerbation of cardiovascular disease occurs, the dosage of thyroid hormone should be reduced, even at the expense of achieving euthyroid state. Thyroid hormones should not be administered to patients with an acute myocardial infarction that is not complicated by hypothyroidism.

High Blood Pressure

Major:

thyroid desiccated

Thyroid desiccated has a major potential interaction with High Blood Pressure.

Thyroid hormones cause increases in myocardial contractility and heart rate as a result of increased metabolic demands and oxygen consumption. Therapy with thyroid hormones should be administered cautiously and initiated at reduced dosages in patients with cardiovascular disorders such as angina, coronary artery disease, and hypertension. Clinical monitoring of cardiovascular function is recommended. If chest pain or exacerbation of cardiovascular disease occurs, the dosage of thyroid hormone should be reduced, even at the expense of achieving euthyroid state. Thyroid hormones should not be administered to patients with an acute myocardial infarction that is not complicated by hypothyroidism.

Hyperthyroidism

Major:

thyroid desiccated

Thyroid desiccated has a major potential interaction with Hyperthyroidism.

The use of thyroid hormones is contraindicated in patients with untreated thyrotoxicosis of any etiology, since thyroid hormones may exacerbate the condition.

Multiple Endocrine Neoplasia Type II

Major:

semaglutide

Semaglutide has a major potential interaction with Multiple Endocrine Neoplasia Type II.

The use semaglutide is contraindicated in patients with a personal or family history of medullary thyroid carcinoma (MTC) or in patients with multiple endocrine neoplasia syndrome type 2 (MEN 2). Patients with elevated serum calcitonin or thyroid nodules noted on physical examination or neck imaging should be further evaluated. It is recommended to counsel patients regarding the potential risk for MTC with the use of semaglutide and inform them of symptoms of thyroid tumors.

Seizures

Moderate:

thyroid desiccated

Thyroid desiccated has a moderate potential interaction with Seizures.

Thyroid hormones may alter the seizure threshold. Seizures have been reported rarely following the initiation of levothyroxine therapy. Therapy with thyroid hormones should be administered cautiously in patients predisposed to seizures.

Thyroid Tumor

Major:

semaglutide

Semaglutide has a major potential interaction with Thyroid Tumor.

The use semaglutide is contraindicated in patients with a personal or family history of medullary thyroid carcinoma (MTC) or in patients with multiple endocrine neoplasia syndrome type 2 (MEN 2). Patients with elevated serum calcitonin or thyroid nodules noted on physical examination or neck imaging should be further evaluated. It is recommended to counsel patients regarding the potential risk for MTC with the use of semaglutide and inform them of symptoms of thyroid tumors.

Vomiting

Moderate:

semaglutide

Semaglutide has a moderate potential interaction with Vomiting.

There have been postmarketing reports of acute kidney injury (sometimes requiring hemodialysis) in patients treated with semaglutide. The majority of events occurred in patients with gastrointestinal adverse reactions leading to dehydration (e.g., nausea, vomiting, diarrhea); therefore, semaglutide is not recommended in patients with severe gastroparesis.
