Is any of this happening?
Be seen today
Treat any suspected oral diabetes medicine overdose as urgent.
Do not wait for symptoms, and do not drive yourself if you feel weak, confused, or sleepy.
New confusion, repeated low glucose, worsening vomiting, rapid breathing, or increasing drowsiness requires urgent reassessment rather than waiting for a routine appointment.
