Tebonin is an herbal supplement, manufactured in Germany, containing EGb 761, an extract of Ginkgo biloba. It is typically used to treat tinnitus and vertigo, as well as circulatory and cognitive health. The manufacturers of Tebonin state there are no side effects associated with taking this supplement. However, since Ginkgo biloba is the main ingredient, you would be wise to make note of its side effects.

Blood Complications

Ginkgo biloba enhances the effect of blood thinners so anyone who is taking prescribed blood thinners should avoid taking Tebonin.

Other Drugs

Ginkgo biloba increases the danger of seizures when taken with antidepressants. Ginkgo decreases the effectiveness of immunosuppressant drugs.


Since Ginkgo biloba is not recommended for use during pregnancy; therefore, pregnant women should not use Tebonin.

Blood Sugar

Blood sugar levels and insulin can be affected by Ginkgo biloba so diabetics should only use Tebonin under the guidance of their physician.


As with any prescription medication or herbal supplements, Tebonin should be kept out of the reach of children.
