What should I discuss with my healthcare provider before taking digoxin (Digitek, Lanoxicaps, Lanoxin)?

You should not use this medication if you are allergic to digoxin, or if you have ventricular fibrillation (a heart rhythm disorder of the ventricles, or lower chambers of the heart that allow blood to flow out of the heart).

If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before using digoxin, tell your doctor if you have:

• certain heart conditions, especially "AV block" (unless you have a pacemaker);
• a recent history of heart attack;
• kidney disease;
• a thyroid disorder;
• an electrolyte imbalance (such as low levels of calcium, potassium, or magnesium in your blood); or
• if you are malnourished or have recently been sick with vomiting or diarrhea.

FDA pregnancy category C. Digoxin may be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.

Digoxin can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Older adults may be more likely to have side effects from digoxin.

How should I take digoxin (Digitek, Lanoxicaps, Lanoxin)?

Take this medication exactly as prescribed by your doctor. Do not take it in larger amounts or for longer than recommended. Follow the directions on your prescription label.

Take digoxin with a full glass of water.

Try to take the medication at the same time every day.

Measure liquid medicine with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

To be sure this medication is not causing harmful effects, your blood may need to be tested on a regular basis. Your kidney function may also need to be tested. Do not miss any scheduled appointments.

Keep taking digoxin as directed, even if you feel well. Get your prescription refilled before you run out of medicine completely.

Do not stop taking digoxin without first talking to your doctor. Stopping suddenly may make your condition worse.

Store this medication at room temperature away from moisture and heat.
