What this interaction means in plain words

Glyburide and Sodium bicarbonate have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Glyburide belongs to Endocrine; Sodium bicarbonate belongs to Gastrointestinal Tract.

Why it happens
