Lanoxin is a well-known and reliable medicine taken to treat patients with moderate and mild congestive heart failures, abnormal heart rhythms and atrial fibrillation. Some doctors also prescribe it to increase myocardial contractility in infants who have heart failure.
How Lanoxin Works and How Patients Use It
The intake of this medicine increases the effectiveness and strength of heart contractions because it inhibits a special enzyme that controls the movement of such minerals as potassium, calcium and sodium into heart muscles. Lanoxin can alleviate such unwanted symptoms as chest pain, dizziness, weakness and shortness of breath because it blocks electrical conduction between ventricles and atria, thus, reducing ventricular contractions.
You need to take this medicine orally once a day, with and without food. However, the human body may not absorb it well if you combine it with food products that are high in fiber. Your daily dosage is prescribed by qualified doctors based on your body weight, age, tolerance and other important aspects. Nowadays, you can find Lanoxin as special injectable solutions and standard tablets available in different doses to suit all patients.
Serious, Moderate and Mild Side Effects
Some of the most common mild side effects caused by this therapy include:
Vomiting and nausea;
Diarrhea and mental changes;
Dizziness and headaches;
Skin rash and allergic reactions.
Most of these symptoms are dose-dependent, so they can be avoided by taking lower doses. Once you develop any serious side effects, you need to call doctors immediately:
Unusual vision changes;
Dangerous Drug Interactions with Lanoxin
You shouldn’t combine it with certain medications because they lead to unwanted drug interactions, severe side effects and other problems. For example, it’s not allowed to take Lanoxin with psyllium, colestipol, antacids, cholestyramine, milk of magnesia, tetracycline, beta blockers, diuretics, ritonavir and some others. You should make a list of other medications that you need to take and show it to your physician to eliminate the ones that cause possible drug interactions.
Other Important Precautions and Contraindications
Before using Lanoxin, you should be examined by doctors and your medical history must be discussed in detail. Let your physician know whether you have any allergic reactions, mineral imbalances, thyroid diseases, kidney problems and other health conditions. The right balance of specific natural minerals in the blood may affect the functioning of this medication in your body. Such drugs as water pills or diuretics affect this balance, so they should be avoiding when taking Lanoxin. Find out if you need to follow special diet plans or take nutritional supplements during this treatment. Infants are more sensitive to its side effects, while pregnant or nursing women should be careful with its use.
