Digoxin (Lanoxin) is a drug that is used to control heart rate. Individuals with hypothyroidism tend to be more sensitive (respond more) to digoxin, and, conversely, individuals with hyperthyroidism are less responsive to digoxin. Therefore, increasing the level of thyroid hormone in the body may warrant an increase in the dose of digoxin. The mechanism for this interaction is not clear, but it may involve changes in the absorption of digoxin, digoxin metabolism, or the effects of thyroid hormone on the heart.
[Digoxin is used to treat congestive heart failure and the associated symptoms of shortness of breath when lying flat, wheezing, and ankle swelling. Digoxin is also used to slow heart rate in rapid atrial rhythm disturbances such as atrial fibrillation and atrial flutter]

Because the plasma of your blood (the fuid without the red cells) has a "limit" of saturation, and can carry les thyroxine when you are taking thyroxine, or viceversa.
Because digoxin has a very slow limit for toxicity (the maximun dose varies between 0.25 and 0.5 miligrams per day) its safer to increase the Thyroxine by roughly one quarter or one third, to make it available to the tissues of the body. (that is what is called biodisponibility.....sorry, There is another little "word" that will surely keep you busy
No big deal in that...
