Summary
Oral cefuroxime axetil absorption is better in an acidic stomach, and antacids such as sodium bicarbonate raise gastric pH. This can reduce cefuroxime exposure and might weaken the antibacterial effect.
What this interaction means in plain words
Cefuroxime and Sodium bicarbonate can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Cefuroxime belongs to Anti Bacterial; Sodium bicarbonate belongs to Gastrointestinal Tract.
Why it happens
Higher gastric pH reduces dissolution and absorption of cefuroxime axetil.
What to do
Separate sodium bicarbonate from oral cefuroxime axetil by about 2 hours, taking cefuroxime with food. Use an alternative antibiotic if acid suppression cannot be avoided in a serious infection.
