[gotcha] Taking Tetracycline or Ciprofloxacin with milk or antacids

Take fluoroquinolones and tetracyclines with water, 2 hours before or after dairy, antacids, or iron supplements.

Journey Context:
Agents might suggest taking pills with meals to reduce stomach upset. Calcium, magnesium, and iron chelate \(bind\) with these specific antibiotics in the GI tract, rendering them completely unabsorbed and ineffective, leading to treatment failure. The trap is prioritizing GI comfort over pharmacokinetics.
