What are other drugs I can substitute for nadalol? Insurance has stopped covering it?

It really depends greatly on why you take the medication. Propranolol, Atenolol, Metoprolol, Corgard, Topamax, Toprol, Inderal and Amitriptyline are some of the most similar alternatives but there are more even than these. You may look into each to see if they target the issues you are having. Best wishes!
