Summary

Canagliflozin has been associated with small increases in serum potassium, particularly in patients with renal impairment, and ACE inhibitors also raise potassium. The combination may contribute to hyperkalemia. Both drugs may also cause volume depletion and affect renal function.

What this interaction means in plain words

Canagliflozin and Fosinopril 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; Fosinopril belongs to Cardiovascular.

Evidence level: Moderate

Why it happens

ACE inhibition reduces aldosterone-mediated potassium excretion while canagliflozin may modestly raise potassium and reduce volume and renal perfusion.

What to do

Monitor serum potassium and renal function after starting canagliflozin. Assess volume status and adjust therapy if hyperkalemia or volume depletion develops.

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?
