Lanoxin tablets are typically taken by mouth with or without food, usually once daily or as directed by a doctor. Follow the prescribed dosage and do not stop taking the medication without consulting a doctor, as some conditions may worsen if the drug is suddenly stopped. Take Lanoxin at least 2 hours before or after consuming high-fiber foods or taking certain medications, such as cholestyramine, colestipol, psyllium, antacids, kaolin-pectin, milk of magnesia, metoclopramide, sulfasalazine, or aminosalicylic acid.
Use Lanoxin regularly to get the maximum benefit from it and use it at the same time each day to help you remember. Do not stop taking this medication without consulting your doctor, as some conditions may worsen if the drug is suddenly stopped.
