Summary
Oral sulfate bowel preparations cause rapid gut transit and diarrhea, which can reduce digoxin absorption. Resulting electrolyte disturbances can also alter digoxin sensitivity and increase toxicity risk.
What this interaction means in plain words
Digoxin and Sodium sulfate / potassium sulfate / magnesium sulfate can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Rapid intestinal transit and possible binding reduce digoxin absorption, and electrolyte loss alters sensitivity to digoxin.
What to do
Give digoxin at least 2 hours before the preparation and not within about 6 hours after it. Check potassium and magnesium and monitor digoxin response.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
