The Good, The Bad, and The Ugly: Antibiotics
Cold & flu season is here!
As a functional medicine doctor, I focus on supporting your immune system and gut naturally.
Prescription Antibiotics: What They Really Do
Penicillins – amoxicillin, ampicillin, penicillin
Kill bacteria, but also good gut bacteria → diarrhea, yeast overgrowth.
Cephalosporins – cephalexin, cefuroxime, ceftriaxone
Broad microbiome disruption; diarrhea, nutrient absorption issues.
Macrolides – azithromycin, clarithromycin, erythromycin
Alter gut flora; nausea, inflammation.
Fluoroquinolones – ciprofloxacin, levofloxacin, moxifloxacin
Gut disruption, mitochondrial stress, tendon/nerve issues.
Tetracyclines – doxycycline, minocycline, tetracycline
Gut disruption; photosensitivity.
Aminoglycosides – gentamicin, amikacin, tobramycin
IV only; kidney & ear toxicity.
Sulfonamides / Trimethoprim – sulfamethoxazole/trimethoprim
Block bacterial folic acid → gut flora disruption.
