Frequently asked questions

Why is it given in kidney disease?

Damaged kidneys cannot remove acid well. Sodium bicarbonate neutralises the extra acid, which may protect bones and muscles.

Is it the same as baking soda?

Chemically yes, but medicinal products are made to a pharmaceutical standard. Do not self-treat with kitchen baking soda.

Can it raise my blood pressure?

It contains sodium, which can worsen high blood pressure or swelling in some people. Your doctor will monitor this.
