Sodium Bicarbonate - Hydrochlorothiazide, Labetalol Interaction Details

Interaction Details

Hydrochlorothiazide, Labetalol is classified as belonging to the following category: Thiazide Diuretics

Theoretically, sodium bicarbonate may increase the risk of hypokalemia in patients taking thiazide diuretics.
Thiazide diuretics increase urinary potassium excretion. Orally, use of excessive sodium bicarbonate (such as the intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, the most common complication of intravenous sodium bicarbonate is hypokalemia.
