Summary

Antacids such as sodium bicarbonate raise gastric pH and reduce the absorption of oral cefpodoxime proxetil. This lowers antibiotic levels and could lead to treatment failure.

What this interaction means in plain words

Cefpodoxime 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.

Cefpodoxime belongs to Anti Bacterial; Sodium bicarbonate belongs to Gastrointestinal Tract.

Evidence level: High

Why it happens

Higher gastric pH impairs dissolution and absorption of cefpodoxime proxetil.

What to do

Separate cefpodoxime from the antacid by at least 2 hours, giving cefpodoxime first, and take it with food. Avoid regular acid suppression during therapy where possible.
