Summary
Heparin can suppress aldosterone synthesis and cause hyperkalemia, especially with prolonged use or renal impairment. Canagliflozin has little direct effect on potassium, so the additive risk is modest and mainly relevant when kidney function is reduced.
What this interaction means in plain words
Canagliflozin-metformin and Heparin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Canagliflozin-metformin belongs to Endocrine; Heparin belongs to Cardiovascular.
Why it happens
Heparin inhibits adrenal aldosterone production, reducing renal potassium excretion; canagliflozin adds only a minor, indirect effect through volume and renal changes.
What to do
Check serum potassium and renal function in patients on prolonged heparin, especially with CKD or other potassium-raising drugs. No routine dose change is needed.
