Uses for Lanoxicaps

Digoxin is used to treat congestive heart failure, usually in combination with a diuretic (water pill) and an angiotensin-converting enzyme (ACE) inhibitor. It is also used to treat a heart rhythm problem called atrial fibrillation.

Digoxin belongs to the class of medicines called digitalis glycosides. It is used to improve the strength and efficiency of the heart, or to control the rate and rhythm of the heartbeat. This leads to better blood circulation and reduced swelling of the hands and ankles in patients with heart problems.

This medicine is available only with your doctor's prescription.

Before using Lanoxicaps

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies on the relationship of age to the effects of digoxin have not been performed in the pediatric population. However, infants are more likely to be very sensitive to the effects of digoxin which may require an individual dose for infants receiving digoxin.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of digoxin in the elderly. However, elderly patients are more likely to have age-related kidney or heart problems which may require caution and an adjustment in the dose for patients receiving digoxin.

Breast Feeding

Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.
