Question 1

What is Westhroid?

Accepted Answer

Westhroid is a natural preparation derived from porcine thyroid glands. It serves as a source of the hormones thyroxine and triiodothyronine, which are naturally produced by the human thyroid gland.

These hormones are essential for regulating the body's energy and metabolism. Westhroid functions by providing these hormones to help maintain normal physiological levels within the body.

Question 2

What is Westhroid used for?

Accepted Answer

Westhroid is used to treat hypothyroidism .

Question 3

How does Westhroid work?

Accepted Answer

Westhroid is a natural thyroid replacement medication derived from porcine (pig) thyroid glands. It contains two primary hormones: thyroxine (T4) and triiodothyronine (T3). These hormones are essential for the body to function correctly, helping to regulate metabolism, body temperature, and energy levels.

When the thyroid gland does not produce enough of these hormones naturally, Westhroid provides the necessary replacement to restore normal levels. Once ingested, the hormones enter the bloodstream. Thyroxine (T4) is converted by the body into triiodothyronine (T3), which is the more active form of the hormone.

While the exact cellular mechanisms are not fully understood, thyroid hormones are known to increase the metabolic rate of tissues and influence the metabolism of carbohydrates, proteins, and lipids. They work by entering cells and binding to receptors that help control how the body uses energy and maintains organ function.

Question 6

What drug class is Westhroid?

Accepted Answer

Question 7

What is the dosage of Westhroid and how do I take it?

Accepted Answer

How to Take This Medication

Westhroid is taken by mouth, usually as a single dose once per day. To help your body absorb the medicine properly, it is best to take it on an empty stomach, at least 30 to 60 minutes before eating breakfast. You should swallow the tablet with a full glass of water.

It is important to take this medication at the same time every day to keep a steady level of thyroid hormone in your body. Do not change your dose or stop taking the medication without consulting your healthcare provider, even if you feel well. This treatment is often required for life.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time to make up for a missed one.

Monitoring

Your doctor will perform regular blood tests to check your thyroid levels and ensure you are receiving the correct amount of medication. Your dosage may be adjusted based on these results.

Question 8

Is Westhroid safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Thyroid hormones do not easily cross the placental barrier. Clinical experience indicates that thyroid replacement therapy does not typically cause adverse effects on the fetus. Maintaining normal thyroid levels is important for the health of both the mother and the developing baby, and treatment for an underactive thyroid should not be stopped during pregnancy.

Because thyroid hormone needs often increase during pregnancy, dosage adjustments may be required. Healthcare providers usually monitor thyroid function tests more frequently during this time to ensure the dose remains effective.

Breastfeeding

Small amounts of thyroid hormones are excreted into human breast milk. While no specific risks have been identified, caution is advised when using Westhroid while nursing. It is important to discuss the use of this medication with a healthcare professional to determine the best course of action for both the mother and the infant.

Question 9

What forms and strengths does Westhroid come in?

Accepted Answer

Westhroid is supplied in the following form:

Oral Tablet: This medication is taken by mouth, typically once daily on an empty stomach.

Question 10

What is the FDA approval status of Westhroid?

Accepted Answer

FDA Boxed Warning

Westhroid contains a boxed warning, which is the most serious safety warning required by the FDA. This warning states that thyroid hormones, including Westhroid, should not be used for the treatment of obesity or for weight loss. In patients with normal thyroid function, doses within the range of daily hormonal requirements are ineffective for weight reduction. Larger doses may produce serious or even life-threatening toxicity, especially when taken in combination with other drugs used for weight loss.

Approved Indications

Westhroid is used for the following purposes:

Replacement or supplemental therapy in patients with hypothyroidism (low thyroid hormone).

The treatment or prevention of various types of euthyroid goiters, including thyroid nodules and multinodular goiter.

Management of thyroid cancer, specifically to suppress thyroid-stimulating hormone (TSH) levels.

Regulatory Context

Westhroid is a desiccated thyroid extract derived from porcine (pig) thyroid glands. It belongs to a category of older medications that were marketed before the FDA's modern drug approval process. As a result, while it is available by prescription, it may not have a formal New Drug Application (NDA) approval on file with the FDA. The medication is manufactured by RLC Labs.

Question 11

What should I know about Westhroid and weight loss?

Accepted Answer

Weight Loss Warning

Westhroid should not be used for the treatment of obesity or for weight loss. In patients with normal thyroid function, doses within the range of daily hormonal requirements are ineffective for weight reduction.

Taking larger doses of thyroid hormone to lose weight can cause serious or even life-threatening symptoms of toxicity. This risk is especially high if Westhroid is taken in combination with other weight-loss medications, such as sympathomimetic amines (anorectics).

Thyroid replacement therapy is intended only for individuals who do not produce enough thyroid hormone naturally. It is not a safe or effective treatment for weight management in people with healthy thyroid levels.
