Summary
Antacid-type products may reduce absorption of oral gemifloxacin, potentially lowering antibiotic exposure. The effect is mainly seen with aluminum and magnesium antacids, and sodium bicarbonate is expected to have a smaller effect.
What this interaction means in plain words
Gemifloxacin and Sodium bicarbonate have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Gemifloxacin belongs to Anti Bacterial; Sodium bicarbonate belongs to Gastrointestinal Tract.
Why it happens
Altered gastric pH and possible reduced absorption of the fluoroquinolone; chelation is less relevant as sodium is not polyvalent.
What to do
Take gemifloxacin at least 2 hours before the oral sodium bicarbonate. No dose change is needed.
What to ask your pharmacist
- Is there anything I should notice while taking both?
