- hyperthyroidism
patients with hyperthyroidism may not respond well to treatment with digoxin but can develop toxicity if the dosage is increased
- hypothyroidism:
patients with hypothyroidism are more sensitive to the effects of digoxin and it can be very difficult to find the correct dosage

Hypothyroidism increases the likelihood of toxicity because elimination of digitalis is depressed and because in this condition the heart is more sensitive to cardiac glycosides.
