Digitalis, also known as digoxin, is a medication commonly used to treat heart conditions such as atrial fibrillation and heart failure. However, it can cause side effects such as dizziness, visual disturbances, fatigue, and loss of appetite, particularly in elderly patients. Coumadin (warfarin) and Pradaxa (dabigatran) are blood thinners that can cause bleeding as a side effect, but do not typically cause the symptoms described. Enalapril is an ACE inhibitor used to treat high blood pressure and heart failure, and while it can cause dizziness and fatigue, it is less likely to cause visual disturbances and loss of appetite.
