What is the treatment of choice for hypothyroidism? What is the mechanism of action? Please provide the initial dose, trade, and generic name of the drug, route, and frequency.

The treatment of choice for hypothyroidism is Levothyroxine (Chiovato et al., 2019). It is mainly marketed under Synthroid, Levoxyl, and Levo T. Levothyroxine works as a synthetic T4 hormone, therefore replacing the low levels of endogenously produced T4 due to reduced thyroid gland function. Once administered, Levothyroxine is activated into triiodothyronine (T3), which is critical in regulating metabolism and production of hormones for growth and development. The initial dose will include levothyroxine 25mcg, which is to be taken orally once daily in the morning.

Q6. What are the adverse effects, and what important teaching will you provide this patient on thyroid replacement therapy?

Thyroid replacement therapy can cause adverse effects, including hyperthyroidism and associated symptoms such as increased heartbeat, heart problems, anxiety, and loss of weight (Kalra et al., 2019). It can also cause osteoporosis. The patient will be educated on the therapy’s risks, medication safety, how to self-administer the therapy, the need for consistent administration of medication, any unexpected symptoms during the therapy, and foods and medications to avoid during the therapy.
