Synthroid: The Synthetic Solution

What is Synthroid?

Synthroid, also known as levothyroxine sodium, is a medication prescribed to individuals with an underactive thyroid gland (hypothyroidism). This medication is a synthetic form of the thyroid hormone thyroxine (T4), which is produced naturally by the thyroid gland. By replacing or supplementing the deficient thyroid hormone, Synthroid helps restore proper hormone levels in the body.

Possible Side Effects of Synthroid

When taking Synthroid, there is a possibility of experiencing certain side effects. These side effects may vary from person to person, but the most commonly reported ones include:

  1. Hair loss
  2. Weight changes
  3. Insomnia
  4. Headaches
  5. Heat intolerance

It’s important to note that not everyone will experience these side effects, and most individuals tolerate Synthroid well. However, if you encounter any severe or persistent side effects, it’s crucial to consult your healthcare provider.

How Should Synthroid be Taken?

Synthroid should be taken exactly as prescribed by your healthcare provider. To ensure optimal absorption, it is recommended to take Synthroid on an empty stomach, at least 30 minutes before eating or consuming any other medications or supplements. This allows for proper absorption of the medication and prevents interference with its effectiveness.

It’s important to follow your prescribed dosage and not adjust it without consulting your healthcare provider. Regular monitoring of thyroid hormone levels and periodic follow-ups with your doctor are necessary to ensure the correct dosage and optimal treatment outcome.

Armour Thyroid: The Natural Alternative

What is Armour Thyroid?

Unlike Synthroid, Armour Thyroid is a natural thyroid hormone medication made from desiccated pig thyroid glands. It contains both thyroxine (T4) and triiodothyronine (T3), the two main hormones produced by the thyroid gland. Armour Thyroid is often prescribed to individuals with hypothyroidism who prefer a more natural approach to hormone replacement therapy.

Possible Side Effects of Armour Thyroid

While Armour Thyroid is generally well-tolerated, it is essential to be aware of potential side effects. Some individuals may experience:

  1. Chest pain
  2. Rapid or irregular heartbeat
  3. Excessive sweating
  4. Tremors
  5. Weight loss

It’s crucial to promptly seek medical attention if you encounter any severe or persistent side effects while taking Armour Thyroid.

How Should Armour Thyroid be Taken?

Unlike Synthroid, Armour Thyroid can be taken with or without food. However, it’s important to follow your healthcare provider’s dosage instructions carefully. Regular thyroid hormone level monitoring and doctor follow-ups are necessary to ensure the appropriate dosage and optimal treatment efficacy.

  • Antacids containing aluminum or magnesium
  • Cholestyramine
  • Ferrous sulfate (iron supplements)
  • Sucralfate
  • Certain cholesterol-lowering medications

It is important to inform your healthcare provider about all the medications and supplements you are taking to prevent any potential interactions with Synthroid.

  • Oral diabetes medications
  • Blood thinners
  • Estrogen-containing medications
