Glyburide Drug Interactions

If other medications are taken with glyburide, drug interactions are possible. For example, a combination of glyburide with beta blockers, certain decongestants, and oral contraceptives can cause the body to metabolize the medications differently than intended and increase the risk of low blood sugar or make glyburide less effective. If glyburide drug interactions are a concern, your healthcare provider may adjust your dosages.
