Summary
Oral magnesium salts may raise the absorption of sulfonylureas such as glyburide, leading to higher plasma concentrations and a stronger glucose-lowering effect. This could increase the risk of hypoglycemia in some patients.
What this interaction means in plain words
Glyburide-metformin and Trimagnesium have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Magnesium salts are thought to alter gastric pH and GI transit, which increases the absorption of glyburide.
What to do
Monitor blood glucose when magnesium-containing products are started or stopped, and counsel the patient on hypoglycemia symptoms. Reduce the glyburide dose if hypoglycemia occurs.
