Diabetes Home > Goji Drug Interactions

When blood pressure medications, warfarin, or diabetes medications are taken with goji, drug interactions could occur. These interactions may increase the risk of low blood pressure, dangerously low blood sugar, and bleeding (including dangerous internal bleeding). In order to help prevent these interactions, tell your healthcare provider about all other medicines you are taking before using goji supplements.

An Introduction to Goji Drug Interactions

Even though it is a natural product, goji can potentially interact with a few medicines. Some of the medicines that may lead to drug interactions with goji include:

More Information on Interactions With Goji

The following sections explain in detail the potentially negative interactions that can occur when goji is combined with any of the drugs listed above.
Blood Pressure Medications
Theoretically, goji root bark might interact with high blood pressure medications, potentially increasing the risk of low blood pressure (hypotension). Be sure to watch for signs of low blood pressure, such as lightheadedness, dizziness, or fainting. It is not clear if goji berries or juice made from the berries also has such effects.
Diabetes Medications
Theoretically, goji root bark may increase the risk of dangerously low blood sugar (hypoglycemia) due to diabetes medications. It is not clear if the berries or juice also have this potential. You may need to monitor your blood sugar more often if you are taking goji supplements.
There have been cases of increased international normalized ratio (INR, a laboratory test that measures blood coagulation) in people taking goji with warfarin. This means that combining these two products could increase the risk of bleeding, including dangerous internal bleeding. If you take warfarin, it is probably best to avoid goji.
