(weakness, hunger, dizziness, tremors, anxiety, tachycardia, sweating), hyperglycemia; even though product does not cause hypoglycemia, if

•
For stress, surgery, or other trauma that may require change in dose
•
Monitor AST, ALT q3mo × 1 yr and periodically thereafter; if elevated, dose may need to be reduced or discontinued, usually increased with doses ≥300mg/day; A1c q3mo, monitor serum glucose, 1 hr PP throughout treatment
•
GI side effects for tolerability/compliance
•
Storage in tight container in cool environment
•

•
The symptoms of hypo/hyperglycemia, what to do about each
•
That medication must be taken as prescribed; explain consequences of discontinuing medication abruptly; that insulin may need to be used for stress, including trauma, surgery, fever
