Urine pH target for Calcium Oxalate stones

Dosing NoLith

Starting dosing is typically 1 scoop (30mEq potassium citrate), mixed with 16 ounces of water.

Dosing may be adjusted up or down according to urinary pH as determined by the health care provider.

If more than 1 scoop is needed per day, doses should be separated and taken in morning and late afternoon.

If more fluid intake versus citrate is needed or desired a 1/2 scoop of NoLith offers 15mEq of potassium citrate and makes a lighter flavored drink when mixing it with 16 ounces of water.

Contraindications to NoLith

NoLith is contraindicated in the following:

  • People with hyperkalemia (elevated potassium) or people with a condition that may predispose them to elevated potassium. This may include people with chronic kidney disease, uncontrolled diabetes, acute dehydration, strenuous exercise for those who are unconditioned, adrenal insufficiency, extensive tissue breakdown.
  • People with peptic ulcer disease.
  • People with an active urinary tract infection.
  • People with reduced kidney function.

Elevated potassium levels can increase the risk of heart rhythm abnormalities and other symptoms like muscle weakness. It can be life threatening.

About Medical Foods

Unlike pharmaceuticals and supplements a medical food, as defined in section 5(b)(3) of the Orphan Drug Act (21 U.S.C. 360ee(b)(3)), is “a food which is formulated to be consumed or administered enterally under the supervision of a physician and which is intended for the specific dietary management of a disease or condition for which distinctive nutritional requirements, based on recognized scientific principles, are established by medical evaluation.” Medical Foods, including NoLith can be purchased OTC without a prescription. NoLith is made in the USA in an FDA inspected facility under cGMP guidelines.
