Urgent Care Urgent Care Medications and Prescribing 2

Question 1

A patient taking warfarin is prescribed trimethoprim-sulfamethoxazole (TMP-SMX) for a UTI. What is the key concern?

Accepted Answer

TMP-SMX inhibits CYP2C9, raising INR and increasing bleeding risk

Answer

TMP-SMX inhibits CYP2C9, reducing warfarin metabolism and significantly elevating INR, which increases the risk of major bleeding.

Question 2

Which medication is contraindicated in a pregnant patient presenting with a UTI?

Accepted Answer

Trimethoprim-sulfamethoxazole in the third trimester

Answer

TMP-SMX is contraindicated near term (third trimester) due to the risk of neonatal hyperbilirubinemia and kernicterus.

Question 3

What is the correct prescribing approach to avoid antibiotic resistance when treating mild skin infections in urgent care?

Accepted Answer

Use the narrowest spectrum effective antibiotic for the shortest appropriate duration

Answer

Antibiotic stewardship principles support using the narrowest effective spectrum for the shortest appropriate duration to minimize resistance.
