Edit list (add/remove drugs)

Interactions between your drugs

Moderate

digoxin calcium carbonate

Applies to: digoxin and calcium / vitamin d

Excessive blood levels of calcium can increase the effects of digoxin. Do not exceed the dosage of calcium carbonate prescribed by your doctor or recommended on the product labeling. You should also check with your doctor before using any over-the-counter products that contain calcium, such as vitamin supplements or antacids. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

digoxin ergocalciferol

Applies to: digoxin and calcium / vitamin d

Ergocalciferol can increase the levels of calcium in your body. Since calcium can enhance the effects of digoxin on the heart, using too much ergocalciferol can cause digoxin toxicity and irregular heart rhythm. If your doctor prescribes these medications together, you may need a dose adjustment or more frequent blood tests to monitor calcium and digoxin levels. You should use ergocalciferol exactly as directed and avoid large increases in your daily dietary calcium intake while using ergocalciferol. Contact your doctor if you experience symptoms that could indicate high blood calcium, such as weakness, fatigue, headache, drowsiness, dizziness, ringing in the ears, loss of appetite, nausea, vomiting, constipation, dry mouth, a metallic taste in the mouth, bone or muscle pain, incoordination, frequent urination, and weight loss. You should also seek medical attention if you experience symptoms of digoxin toxicity such as nausea, vomiting, blurred vision, slow pulse, or irregular heartbeats. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food interactions

Moderate

calcium carbonate food

Applies to: calcium / vitamin d

Calcium absorption may be increased by taking it with food. However, foods high in oxalic acid (spinach or rhubarb), or phytic acid (bran and whole grains) may decrease calcium absorption. Calcium may be taken with food to increase absorption. Consider spacing calcium administration for at least 2 hours before or after consuming foods high in oxalic acid or phytic acid. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Consumer information for this interaction is not currently available.

MONITOR: Additive effects and possible toxicity (e.g., hypercalcemia, hypercalciuria, and/or hyperphosphatemia) may occur when patients using vitamin D and/or vitamin D analogs ingest a diet high in vitamin D, calcium, and/or phosphorus. The biologically active forms of vitamin D stimulate intestinal absorption of calcium and phosphorus. This may be helpful in patients with hypocalcemia and/or hypophosphatemia. However, sudden increases in calcium or phosphorus consumption due to dietary changes could precipitate hypercalcemia and/or hyperphosphatemia. Patients with certain disease states, such as impaired renal function, may be more susceptible to toxic side effects like ectopic calcification. On the other hand, if dietary calcium is inadequate for the body's needs, the active form of vitamin D will stimulate osteoclasts to pull calcium from the bones. This may be detrimental in a patient with reduced bone density.

MANAGEMENT: Given the narrow therapeutic index of vitamin D and vitamin D analogs, the amounts of calcium, phosphorus, and vitamin D present in the patient's diet may need to be taken into consideration. Specific dietary guidance should be discussed with the patient and regular lab work should be monitored as indicated. Calcium, phosphorus, and vitamin D levels should be kept within the desired ranges, which may differ depending on the patient's condition. Patients should also be counseled on the signs and symptoms of hypervitaminosis D, hypercalcemia, and/or hyperphosphatemia.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
