SN also instructed pt on the disease process of hypothyroidism. The thyroid gland controls a lot of our body functions, when it is unable to produce the amount of thyroid hormone your body needs, you will need to take this hormone orally. Take this medication everyday as ordered by your MD. Report to SN or MD if you have sensitivity to cold temperature, dry skin, constipation, forgetfulness, chronic fatigue, decreased heart rate, depression, hair loss, weight gain, muscle stiffness and cramping, as these can be signs your medication is not the correct dose.
