Levoxyl May Cause Choking, Says FDA
Oct. 6, 2004 – Levoxyl, a thyroid hormone replacement drug, may
cause choking and gagging when it is not swallowed with a full glass
of water, the drug's manufacturer and the Food and Drug
Administration warned Tuesday.
Jones Pharma Inc., a subsidiary of King Pharmaceuticals, issued a
letter warning doctors that the thyroid hormone replacement can
rapidly swell and disintegrate, catching in patients' throats and
causing difficulty swallowing.
These problems usually disappeared when the drug, primarily used to
treat hypothyroidism, was taken with a full glass of water.
Consumers with questions may call Jones Pharma at 1-800-776-3637.
