Diazoxide
Albuterol Oral Inhalation
How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
Both of these medicines can lower your potassium. Diazoxide (Proglycem, Vykat) can push potassium levels down, and albuterol, your inhaler, can do the same, especially if you use more than directed. When potassium drops too low, it can affect your heart's rhythm, which sometimes shows up as changes on an EKG.
The good news is this concern is mostly theoretical, and it is very manageable. Keep using both medicines exactly as prescribed. Your care team can simply check your potassium level now and then and watch how you are doing. If you ever feel muscle cramps, weakness, or a fluttering heartbeat, let your pharmacist or doctor know.
Additive hypokalemic risk. Both agents lower serum potassium: diazoxide has potassium-depleting effects, and beta-2 agonists like albuterol drive intracellular potassium shift. Combined use may potentiate hypokalemia and associated ECG changes (e.g., QT prolongation, arrhythmia risk).
- Direction: additive PD effect lowering K+ (neither drug is a prodrug).
- Onset: unspecified.
- Evidence: theoretical.
- Magnitude: greatest with albuterol doses exceeding recommendations.
- Management: monitor serum potassium during concurrent therapy; obtain ECG if clinically indicated; correct hypokalemia and reinforce appropriate inhaler dosing.
What happens
An increased risk of ECG changes or hypokalemia
Interaction Deep Dive
Exercise caution when albuterol is given together with a diuretic that depletes potassium. Taking albuterol, which is a beta-adrenergic agonist, alongside a potassium-depleting diuretic (for example, a thiazide or loop diuretic) can heighten the likelihood of hypokalemia or ECG alterations, particularly when beta-agonist doses go beyond what is recommended. Monitoring of potassium levels while a patient is receiving albuterol should be considered12.
Why it happens (mechanism)
Potentiation of diuretic-induced ECG changes and hypokalemia by albuterol
How to manage this interaction
Keep taking both as prescribed and use your albuterol inhaler only as directed. Higher-than-recommended doses raise the risk the most.
- Your care team may check your potassium level from time to time during treatment.
- If potassium runs low, your team can adjust things and individualize your care to correct it.
- An ECG may be ordered if there is any concern about your heart rhythm.
Tell your pharmacist or doctor if you notice muscle weakness, cramps, an irregular or racing heartbeat, or if you find yourself needing your inhaler more than usual.
Management is individual — confirm any change with your pharmacist or prescriber.
