GABA (
gamma-aminobutyric acid) does not have any known drug interactions. However, you should always tell your healthcare provider about any other medications or supplements you are taking, including prescription drugs, nonprescription drugs, vitamins, and dietary or herbal supplements. Even though there are no known drug interactions with GABA at this time, it is important to understand that GABA supplementation has been studied very little in humans. It has certainly not been studied enough to rule out the possibility of interactions.
If you suspect an interaction between GABA and a medication you are taking, let your healthcare provider know. He or she can help you investigate the possibility. If your healthcare provider also suspects that a drug interaction has occurred, he or she might want to report it to a medical journal, especially if it is a significant or particularly interesting interaction.
