In Toronto, a mother wants legislation that would force pharmacies to make prescription errors public, reports CBC.

Otherwise a healthy boy, Andrew suffered from a REM sleep disorder called parasomnia that caused him to enter his sleep cycle twice as fast as normal, leading him to wake up as many as five times during the night. A sleep specialist prescribed Tryptophan at bedtime.

He had trouble swallowing pills, so his sleep specialist prescribed a liquid dose in October 2014. That’s when the family began using the liquid compound from Floradale Medical Pharmacy Ltd.

For years, Andrew had no issues with the medication.
