Glimepiride
Ginkgo
In a preliminary trial, administration of Ginkgo biloba extract (120 mg per day) for three months to patients with type 2 diabetes who were taking oral anti-diabetes medication resulted in a significant worsening of glucose tolerance. Ginkgo did not impair glucose tolerance in individuals whose diabetes was controlled by diet. Individuals taking oral anti-diabetes medication should consult a doctor before taking Ginkgo biloba.

- Potential Negative Interaction
Glimepiride
Vitamin B3 (Niacin)
Vitamin B3 can raise blood sugar levels, which makes diabetes difficult to control. Use of niacin along with glimepiride may increase requirements for the drug. On the other hand, individuals who stop taking niacin while on glimepiride should monitor their blood for lower-than-usual glucose levels.

Glimepiride
Magnesium
Supplementing magnesium may enhance the blood-sugar-lowering effects of sulfonylurea drugs. Though no current studies have investigated whether glimepiride increases the risk of developing hypoglycemia, individuals should closely monitor their blood glucose while taking glimepiride together with magnesium supplements.
