In the event of an overdose with this combination the usual supportive measures (i.e. remove unabsorbed material from the gastrointestinal tract, perform clinical monitoring, and institute supportive treatment) should be employed. Removal of Linagliptin by hemodialysis or peritoneal dialysis is unlikely but Metformin Hydrochloride is dialyzable.
During controlled clinical trials in healthy subjects, with single doses of up to 600 mg of Linagliptin (equivalent to 120 times the recommended daily dose), there were no dose-related clinical adverse drug reactions.
Overdose of Metformin Hydrochloride has occurred in case of ingestion of amounts greater than 50 grams. Hypoglycemia was reported in approximately 10% of cases, but no causal association with Metformin Hydrochloride has been established. Lactic acidosis has been reported in approximately 32% of Metformin Hydrochloride overdose cases.
