- at the same time each day.
- If you miss a dose of this medication, take the missed dose as soon as
- possible, unless it is almost time for the next dose. In that case, do not
- take the missed dose at all; just return to your regular dosing schedule. Do
- not double the next dose. If you miss two or more doses, check with your

- condition as long as you continue to take it.

-
- INTERACTIONS
-
- Digitoxin interacts with several other types of medications:
- 1. Barbiturates, phenytoin, aminoglutethimide, levodopa, penicillamine,
- phenylbutazone, and rifampin can decrease the blood levels and effectiveness
- of digitoxin.
- 2. The absorption of digitoxin from the gastrointestinal tract is reduced
- when it is taken with colestipol, cholestyramine, metoclopramide, antacids,
- neomycin, antineoplastic (anticancer) drugs, or sulfasalazine.
- 3. Tetracycline can increase the absorption of digitoxin from the
- gastrointestinal tract, which can increase the risk of side effects.
- 4. Spironolactone can unpredictably increase or decrease the side effects
- of digitoxin.
- 5. Concurrent use of quinidine, procainamide, hydroxychloroquine,
- calcium, reserpine, ephedrine, or beta blockers (acebutolol, atenolol,
- betaxolol, carteolol, esmolol, labetalol, metoprolol, nadolol, penbutolol,
- pindolol, propranolol, and timolol) with digitoxin can lead to additive
- effects on the heart.
- 6. The dosage of digitoxin may require adjustment if therapy with thyroid
- hormones, methimazole, or propylthiouracil is started.
- 7. Concurrent use of digitoxin and quinidine, quinine, erythromycin,
- amiodarone, benzodiazepine tranquilizers, diltiazem, nifedipine, or verapamil
- can increase the blood levels and the side effects of digitoxin.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially those listed above.

- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- medications, especially to digitoxin or any other digitalis glycoside.
- * Before starting to take this medication, be sure to tell your doctor if
- you now have or if you have ever had blood electrolyte disorders (too much or
- too little calcium, magnesium, or potassium), heart disease, kidney disease,
- lung disease, liver disease, or thyroid disease.
- * Before having surgery or any other medical or dental treatment, be sure
- to tell your doctor or dentist that you are taking this medication.
- * Check with your doctor or pharmacist before taking any over-the-counter
- (nonprescription) allergy, asthma, cough, cold, diet, or sinus products. Some
- of these products can increase the side effects of digitoxin.
- * Do not stop taking this medication unless you first check with your
- doctor. Stopping abruptly may lead to a worsening of your condition.
- * While you are taking digitoxin, your doctor may want you to check your
- pulse every day. If your pulse is slower than your doctor has told you it
- should be or if the rhythm is irregular, CONTACT YOUR DOCTOR IMMEDIATELY.
- * Be sure to tell your doctor if you are pregnant. Although digitoxin
- appears to be safe during pregnancy, extensive studies in humans have not been
- conducted. In addition, the dosage of digitoxin required to control your
- disorder may change during pregnancy. Also, tell your doctor if you are
- breast-feeding an infant. It is not known if digitoxin passes into breast
- milk.
