Summary
Canagliflozin can cause volume depletion and reduced renal perfusion, and may occasionally raise potassium, while telmisartan reduces aldosterone-mediated potassium excretion. Together they may raise the risk of hyperkalemia and acute kidney injury, especially in patients with CKD or diabetes.
What this interaction means in plain words
Canagliflozin and Telmisartan 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.
Canagliflozin belongs to Endocrine; Telmisartan belongs to Cardiovascular.
Why it happens
Additive effects on renal function and potassium handling: ARB-induced aldosterone blockade plus canagliflozin-related volume depletion and hemodynamic changes.
What to do
Monitor serum potassium, creatinine and volume status after starting or changing either drug. Correct volume depletion and reassess doses if renal function declines.
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?
