Summary
MAO inhibitors have been associated with enhanced hypoglycemic effects of antidiabetic drugs. Transdermal selegiline gives lower MAO-A inhibition at low doses, so the effect is likely smaller, but altered glucose control is possible.
What this interaction means in plain words
Chlorpropamide and Selegiline transdermal 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.
Why it happens
Possible additive glucose-lowering effect of MAO inhibition; the mechanism is not clearly established.
What to do
Monitor blood glucose when selegiline is started or the dose is changed. Adjust chlorpropamide if hypoglycemia occurs.
What to ask your pharmacist
