Hi, Charlotte's Mom. This is William's Mom again. Like Charlotte, Williams levels did not improve with the sodium bicarbonate, so they increased it to 1/2 teaspoon of baking soda dissolved in plain water, three times a day. I did look into doing the tablets, because the baking soda tastes awful, but he would have to take 12 tablets a day! He decided drinking the ounce of water and baking soda was better than swallowing all those tablets.
So...if Charlotte is sick of sodium bicarbonate tablets, she could try the baking soda in water and see if she can tolerate the taste. Here's the conversion from the Web:
Approximate Equivalent Dose of Sodium Bicarbonate Powder and Tablets
Sodium Bicarbonate Tablet 650 mg tablet (7.6 mEq sodium) = 1/8 teaspoon baking soda (6.7 mEq sodium)
