Videx EC, the delayed-release form of Videx, may now be taken by children who weigh at least 44 pounds, according to an update to the drug’s prescribing information from the United States Food and Drug Administration (FDA).

Until now, doctors who wished to prescribe Videx for children could only prescribe the older powder and tablet formulations of Videx, both taken twice a day. Videx EC, which is taken once daily, was only available for adults 18 years old and older.

Based on completed studies detailing how Videx EC is absorbed and metabolized in children, the FDA says that the drug may be prescribed safely and effectively for pediatric use. Children who weigh from 44 to less than 55 lbs (20 to less than 25 kg) should take 200 mg once daily. Children who weigh from 55 to less than 132 lbs (25 to less than 60 kg) should take 250 mg once daily. Children who weigh 132 lbs (60 kg) or more should take 400 mg once daily—the same dose used for adults.
