From the Guidelines

Based on your lab results, I strongly recommend increasing your Armour Thyroid dose from 60mg to 90mg daily to address the elevated TSH level and low T4 level, as indicated by your current lab values of T4 0.68, TSH 8.48, and T3 2.12. This adjustment is necessary because your elevated TSH level suggests that your pituitary gland is signaling for more thyroid hormone production, and your low T4 level confirms that you are undermedicated 1. The principal treatment for hypothyroidism, as stated in the USPSTF recommendation statement, is oral T4 monotherapy (levothyroxine sodium), but since you are on Armour Thyroid, which contains both T3 and T4 hormones, finding the right balance often requires gradual adjustments based on both lab values and symptom improvement 1. Key considerations for adjusting your thyroid medication dose include:

  • Monitoring for symptoms of proper thyroid function, such as improved energy, less hair loss, and better temperature tolerance
  • Watching for potential signs of overmedication, including anxiety, rapid heartbeat, and insomnia
  • Retesting your thyroid labs in 6-8 weeks to evaluate the effectiveness of the dose adjustment It is essential to take your medication as directed, in this case, 90mg daily, as a single dose in the morning on an empty stomach, at least 30-60 minutes before eating. If you experience significant palpitations, chest pain, or severe anxiety after the dose adjustment, contact your healthcare provider immediately.

From the Research

Adjusting Armour Thyroid Hormone Dosage

To adjust the Armour thyroid hormone dosage from 60mg, considering the lab results showing T4 0.68, TSH 8.48, and T3 2.12, the following points should be taken into account:

  • The lab results indicate that the current dosage may not be optimal, as the TSH level is elevated and the T4 and T3 levels are not within the desired range.
  • According to the study 2, the approach to thyroid hormone replacement varies across centers, and there is significant geographical variation in prescribing patterns.
  • The study 2 also found that factors such as socioeconomic disadvantage, antidepressant prescribing, and diabetes management can influence levothyroxine and liothyronine prescribing patterns.
  • However, the study 2 does not provide specific guidance on adjusting Armour thyroid hormone dosage based on lab results.
  • It is essential to consult with a healthcare professional to determine the best course of action for adjusting the dosage, as they can assess individual factors and make informed decisions.

Considerations for Dosage Adjustment

When adjusting the Armour thyroid hormone dosage, the following considerations should be taken into account:

  • The patient's symptoms and medical history
  • The lab results, including TSH, T4, and T3 levels
  • The potential interactions with other medications, such as antidepressants
  • The patient's socioeconomic factors and access to healthcare services
  • The healthcare provider's experience and expertise in managing thyroid hormone replacement therapy

Next Steps

The next steps would be to consult with a healthcare professional to discuss the lab results and determine the best course of action for adjusting the Armour thyroid hormone dosage. They can assess individual factors and make informed decisions to optimize the patient's treatment plan.
