Dosage of betaine is expressed in terms of anhydrous drug.

The usual dosage of betaine for the management of homocystinuria in adults and children is 6 g daily administered in 2 equally divided doses. Although children ranging in age from several months to years have been treated successfully and without unusual adverse effects with 6 g daily, dosage titration may be preferable in children. Children younger than 3 years of age may receive an initial betaine dosage of 100 mg/kg daily that is subsequently increased at weekly intervals in increments of 100 mg/kg daily.

All patients may receive gradual increases in betaine dosage until the concentration of homocysteine in plasma is undetectable or present only in small amounts. Some patients have required up to 20 g daily to control concentrations of homocystine in plasma.

Betaine is administered orally as a solution prepared from the anhydrous powder. The solution should be prepared immediately before administration by dissolving the appropriate amount of powder in 120-180 mL of water. The scoop provided by the manufacturer delivers 1 g of betaine anhydrous powder per level scoopful, which apportions 1.7

mL. The solution should not be administered if it is colored or the powder does not dissolve completely.
