Interaction Details
Repaglinide is classified as belonging to the following category: Antidiabetes Drugs
Theoretically, bitter orange might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Some clinical research shows that drinking a tea containing bitter orange and Indian snakeroot reduces fasting and postprandial glucose levels in patients with type 2 diabetes who are using antidiabetes drugs. However, it is unclear if these effects are due to bitter orange, Indian snakeroot, or the combination. An animal study also shows that p-synephrine in combination with gliclazide , a sulfonylurea, causes an additional 20% to 44% decrease in glucose levels when compared with gliclazide alone.

Bitter Orange Overview
Bitter orange, also known as Seville orange or sour orange, is a type of citrus fruit that is native to Southeast Asia. It is closely related to the sweet orange, but has a much more bitter and sour flavor.
Bitter orange is a rich source of vitamin C and other nutrients, including calcium, potassium, and folate. It is also a good source of antioxidants.
Bitter orange has been used in traditional medicine for a number of purported health benefits, including improved digestion, improved immune function, and reduced inflammation.
Bitter orange also contains synephrine, a compound similar in structure to ephedrine. Synephrine is thought to have stimulant effects and is often used to increase energy, improve athletic performance, and as a weight loss supplement. When used as a dietary supplement, the dosage is typically standardized by its synephrine content.
Repaglinide Overview
-
Repaglinide is used to treat type 2 diabetes (condition in which the body does not use insulin normally and, therefore, cannot control the amount of sugar in the blood). Repaglinide helps your body regulate the amount of glucose (sugar) in your blood. It decreases the amount of glucose by stimulating the pancreas to release insulin.
-
Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems.Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
