Which drugs or supplements interact with sodium bicarbonate?

Sodium bicarbonate may increase the blood concentration of flecainide (Tambocor) by increasing the pH of urine, leading to less excretion of flecainide.

Sodium bicarbonate may decrease blood concentration of amphetamines, atazanavir (Reyataz), bisacodyl (Dulcolax), captopril (Capoten), dabigatran (Pradaxa), itraconazole (Sporanox) and many other drugs.

Acetazolamide (Diamox) may increase the risk of toxicity or adverse effects associated with sodium bicarbonate treatment.

Is sodium bicarbonate safe to use during pregnancy or while breastfeeding?

Sodium bicarbonate has not been adequately evaluated in pregnant women. Sodium bicarbonate has the potential risk of causing metabolic alkalosis and fluid overload in pregnancy. Therefore, sodium bicarbonate containing antacids are considered unsafe in pregnancy.

Sodium bicarbonate enters breast milk. Other antacids such as calcium carbonate or magnesium hydroxide are generally preferred over sodium carbonate due to their wider safety margin.

What else should I know about sodium bicarbonate?

What preparations of sodium bicarbonate are available?

Effervescent granules for oral solution: 460 mg. Oral tablet: 325 and 650 mg

How should I keep sodium bicarbonate stored?

Store at room temperature 59 C - 86 C (15 F – 30 F).

How does sodium bicarbonate work?

Oral sodium bicarbonate provides rapid relief (within 15 minutes) of heartburn symptoms and should only be used to provide temporary relief of occasional episodes of stomach acid problems. Oral administration of sodium bicarbonate results in the neutralization of hydrochloric acid in the stomach (raises blood and urinary pH) and the formation of sodium chloride, carbon dioxide, and water.
