Lanoxin is a medication derived from the leaves of the digitalis plant, primarily used to treat heart conditions such as heart failure and irregular heartbeat. Its active ingredient is digoxin, which helps to make the heartbeat stronger and more regularly. Lanoxin helps to control the ventricular response rate in adult patients with chronic atrial fibrillation.
It is available in tablet form and may be used alone or with other medications. Lanoxin is prescribed by a doctor and its use should be carefully monitored due to the potential for serious side effects. Always follow the instructions provided by your healthcare provider when taking Lanoxin.
Uses and Dosage
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.
