Pharmacy Phriday #7: Bactrim Adverse Events
Manage episode 282370006 series 1397179
Contributor: Cheyenne Bean, PharmD
Educational Pearls:
- Bactrim (TMP-SMX) is a sulfa antibiotic used for a number of infections but can have untoward effects.
- Hypoglycemia can be induced by the sulfa component of Bactrim, which binds receptors in the pancreas causing insulin to be secreted, dropping blood sugar levels.
-
- Oral diabetic medications, specifically sulfonylureas, when taken with Bactrim most often lead to these hypoglycemic episodes.
- Hyperkalemia can be induced by Trimethoprim by blocking potassium excretion in the kidney, so Bactrim in combination with ACE inhibitors/ARBs/spironolactone can induce high potassium.
- When prescribing Bactrim, remember to check home medications and if a patient is taking an above medication, check a baseline BGL and potassium.
