Lanoxin is a brand name for digoxin, which belongs to a class of medications called cardiac glycosides. It is used to treat heart failure, atrial fibrillation, and atrial flutter by increasing the strength and regularity of heart contractions. It works by slowing down the heart rate and improving the pumping action of the heart.
Lanoxin is usually taken by mouth as tablets or capsules, but it can also be given by injection. The dosage of Lanoxin depends on the patient's age, weight, medical condition, and other medications they are taking. It is important to follow the dosage instructions provided by the doctor or pharmacist, and to take the medication at the same time each day to maintain a consistent level of the drug in the body.
Common side effects of Lanoxin include nausea, vomiting, diarrhea, loss of appetite, headache, and dizziness. In rare cases, it may cause more serious side effects such as vision changes, confusion, irregular heartbeat, or allergic reactions. Patients should contact their doctor immediately if they experience any unusual symptoms while taking Lanoxin.
