Celine Dion took potentially fatal doses of Valium before Stiff Person Syndrome diagnosis

The My Heart Will Go On singer was prescribed the medication to help her cope with her muscle spasms and stiffness before she was diagnosed with the rare autoimmune neurological disorder in 2022. Celine revealed to host Hoda Kotb on the TV special Celine's Story that she had to keep upping her doses of the muscle-relaxing pill in order to perform to the point where she was taking 90 milligrams a day instead of the maximum dosage of 40 milligrams.
