Levothyroxine nursing considerations
Levothyroxine's nursing considerations are timing and recognizing over-replacement. Take it on an empty stomach in the morning, 30 to 60 minutes before breakfast, every day for life, and do not switch brands. Report chest pain, palpitations, or a racing heart, which signal too much. Monitor the TSH.
What levothyroxine does, and why the NCLEX tests it
Levothyroxine (Synthroid) is synthetic T4 that replaces the missing hormone in hypothyroidism. It is lifelong therapy, and the signs of too much look like hyperthyroidism. The exam tests correct timing and recognizing over-replacement.
