Summary
Both metformin and dalfampridine are eliminated by renal cationic transport, so co-administration could raise exposure to either. Dalfampridine accumulation increases seizure risk, particularly when renal function is reduced.
What this interaction means in plain words
Canagliflozin-metformin and Dalfampridine 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-metformin belongs to Endocrine; Dalfampridine belongs to Central Nervous System.
Why it happens
Competition for renal tubular secretion via OCT2 may reduce clearance of both drugs.
What to do
Check renal function before and during combined use and watch for neurological adverse effects such as tremor or seizures, and for metformin toxicity. Avoid the combination if creatinine clearance is reduced.
