Cerefolin NAC

Warnings & Precautions

Contains milk and soy

CerefolinNAC is a prescription medical food for use only under the supervision of a physician.

Medical foods are intended for a patient who has a limited or impaired capacity to ingest, digest, absorb, or metabolize ordinary foodstuffs or certain nutrients, or who has other special medically determined nutrient requirements, the dietary management of which cannot be achieved by the modification of the normal diet alone.

Contraindications CerefolinNAC is contraindicated in patients with known hypersensitivity to any of the components contained in this product.

Precautions General Folic acid, when administered in daily doses above 0.1mg, may obscure the detection of B12 deficiency (specifically, the administration of folic acid may reverse the hematological manifestations of B12 deficiency, including pernicious anemia, while not addressing the neurological manifestations). L-methylfolate Calcium may be less likely than folic acid to mask vitamin B12 deficiency. Folate therapy alone is inadequate for the treatment of a B12 deficiency.

N-acetyl-L-cysteine should be avoided by nursing mothers.

N-acetyl-L-cysteine clearance is reduced in those with chronic liver disease as well as in pre-term newborns.

Headaches may be intensified in those taking N-acetyl-L-cysteine and nitrates for the treatment of angina.24 While the incidence of renal stones is low, those that do form renal stones, particularly cysteine stones should avoid CerefolinNAC. Do not administer CerefolinNAC to critically ill patients. N-acetyl-L-cysteine and its sulfhydryl metabolites could produce a false-positive result in the nitroprusside test for ketone bodies used in diabetes.24 N-acetyl-L-cysteine should be used with caution in those with a history of peptic ulcer disease since N-acetyl-L-cysteine may disrupt the gastric mucosal barrier.

Adverse reactions Allergic reactions have been reported following the use of oral L-methylfolate Calcium. Mild transient diarrhea, itching, transitory exanthema and the feeling of swelling of the entire body has been associated with methylcobalamin. Nausea, vomiting, diarrhea, transient skin rash, flushing, epigastric pain, and constipation have been associated with N-acetyl-L-cysteine.

Use under medical supervision.
