Summary
Clonidine can blunt some adrenergic warning symptoms of hypoglycemia such as tremor and palpitations, so low blood sugar may go unrecognized in insulin-treated patients. Sweating is generally preserved. Clonidine may also modestly alter glucose control.
What this interaction means in plain words
Clonidine and Insulin nph 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
Central sympatholytic action reduces the catecholamine-mediated autonomic symptoms of hypoglycemia.
What to do
Advise patients to monitor blood glucose more often rather than rely on symptoms, and to recognize sweating and hunger as warning signs.
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?
