Watch for Hypoglycemia in Patients Taking Repaglinide Plus Clopidogrel
You'll hear about a potentially dangerous interaction between clopidogrel (Plavix, etc) and repaglinide (Prandin, etc).
We usually think of clopidogrel as a CYP2C19 substrate. But clopidogrel also INHIBITS CYP2C8...causing repaglinide levels to increase.
In fact, clopidogrel can raise repaglinide levels by over 5-fold... and may lead to significant hypoglycemia.
