Thyroid Disorders and Therapies from Belmar Pharmacy

Belmar Pharmacy offers a variety of therapeutic options to support the body’s thyroid hormone balance. Compounded bioidentical forms of thyroid hormone replacement include synthetic T3/T4 options. Synthetic thyroid hormones are available as liothyronine sodium (T3) or levothyroxine sodium (T4). This form of thyroid hormone is biologically equivalent to the T3 and T4 in the human body, mimicking natural thyroid hormones. These active ingredients can also be compounded into combination oral formulations with both T3/T4.

The thyroid-stimulating hormone (TSH), is a hormone released by the pituitary gland. It tells the thyroid how much and when to release the hormones it produces called thyroxine (T4) and triiodothyronine (T3). If TSH doesn’t trigger the release of T3 and T4 from the thyroid gland, it can adversely affect metabolic, digestive, and heart functions.

There are many factors that can contribute to thyroid problems, including the pituitary gland’s ability to stimulate the thyroid to release its hormones into the body. The two most common thyroid problems are hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). Several conditions can cause thyroid problems, including Hashimoto’s disease, a chronic autoimmune condition that can lead to an underactive thyroid.

Other conditions that may cause thyroid problems include iodine deficiency, Graves’ disease (the most common cause of hyperthyroidism), thyroid nodules, and thyroiditis.

Depending on whether a patient has hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid), they may experience opposite symptoms. If the thyroid is underactive, the patient may feel tired and cold, have a sluggish digestive system, feel depressed, and have trouble losing weight. When someone experiences hyperthyroid symptoms, they may feel anxious, lose weight quickly, have trouble sleeping, sweat easily, and have a faster heart rate. Either condition can cause an enlarged thyroid, or goiter, in the neck.

For women, hypothyroidism can mean heavier menstrual periods, and hyperthyroidism can contribute to irregular periods, or lack of them.

Depending on the type of thyroid medication taken, such as levothyroxine sodium, which is used to address hypothyroidism (underactive thyroid), too much thyroid medication may cause transient symptoms similar to those of hyperthyroidism (overactive thyroid). In this case, the patient may experience excessive sweating, rapid heartbeat, anxiety, diarrhea, weight loss, feeling jittery, shaking hands, and trouble sleeping.

Conversely, if the medication is addressing hyperthyroidism and the dose is too high, the patient may experience the opposite feelings of lethargy, lower heartbeat, feeling cold, depression, and mood swings.

Compounded thyroid replacement therapy allows for dose flexibility, combination therapy, and formulation adjustment. Liothyronine sodium (T3) and levothyroxine sodium (T4) can be combined into a single dosage form to improve ease of administration, and their strengths can be customized to meet individual patient needs. Compounded prescriptions can also be formulated to modify the release of the drug as well as to limit unnecessary fillers.

Proper thyroid function requires the conversion of T4, the primary inactive thyroid hormone, to T3, the body’s active thyroid hormone. Levothyroxine sodium (T4) has a naturally longer half-life. Liothyronine sodium (T3) has a shorter half-life, and patients in need of T3 support may benefit from a compounded modified release formulation. It is recommended to take thyroid hormone replacement therapy roughly 30 to 60 minutes before breakfast. Absorption tends to be higher on an empty stomach (at least 4 hours apart from food or supplements).
