2 interactions related to monitoring
prednisone + potassium
Prednisone has weak mineralocorticoid activity that promotes renal potassium excretion. Especially at higher doses or with prolonged use, this can cause hypokalemia, which presents as muscle weakness, fatigue, and potentially arrhythmias.

levothyroxine + biotin
High-dose biotin (B7) does not directly interact with levothyroxine pharmacologically, but it interferes with biotin-streptavidin immunoassays used for TSH, free T4, free T3, and thyroglobulin. This can produce falsely low TSH and falsely high T4/T3, mimicking hyperthyroidism and leading to inappropriate dose reductions.
