Digoxin + Omeprazole

SAFE — No Known Interaction

🟢 SAFE — Omeprazole and Digoxin can be taken together safely.

Evidence level: MODERATE

What this interaction means

Omeprazole and Digoxin are generally considered safe to use together based on current medical evidence. No adverse interactions have been reported.

How it works (mechanism)

No clinically significant interaction between Omeprazole and Digoxin has been identified in medical literature or FDA drug labeling.

Practical advice

Omeprazole may affect absorption of Digoxin by altering stomach pH. Take Omeprazole 30 minutes before meals. If the other medication requires an acidic environment for absorption, separate dosing by 2 hours.

Timing

Take Omeprazole 30 minutes before a meal — PPIs need an active acid pump to work. Digoxin can follow its own prescribed schedule. PPIs can reduce absorption of acid-dependent drugs, so maintain at least a 2-hour window if in doubt.

Risk factors

Higher risk for: elderly (fracture risk, magnesium depletion), long-term PPI users (>1 year), those with osteoporosis, concurrent clopidogrel use, or those with low magnesium or B12 levels.

Symptoms to watch for

Proton pump inhibitors alter stomach acid and can affect absorption of other medications. Monitor when combining Omeprazole with Digoxin. Watch for: changes in the effectiveness of either medication, persistent digestive discomfort, headache, dizziness, or signs of nutrient depletion (fatigue, muscle cramps, numbness/tingling). When to seek emergency help: Severe diarrhea (possible C. difficile), severe abdominal pain, chest pain, difficulty swallowing, persistent vomiting, or signs of low magnesium (muscle spasms, irregular heartbeat, seizures).

What to tell your doctor

No urgent need to discuss, but always keep your doctor informed of your full supplement and medication list. Say: "I take Omeprazole and Digoxin — is that OK?"

Safer alternatives

These medications are safe to take together at standard doses. Continue taking as prescribed and keep your pharmacist informed of your complete medication list.
