Some acid reflux medications include both sodium alginate and potassium bicarbonate as active ingredients.
When you use them in one medication, they’re perfectly safe to use together as long as you follow the manufacturer’s instructions carefully, as the safe dosages have already been worked out carefully.
However, if you wish to take 2 separate medications that contain these ingredients, or any combination of medications at the same time, you should speak to your doctor or pharmacist for advice first.
They’ll make sure that your medications are safe to use together and that you’re taking the right amount of each.
