Hi, Thank you for posting your questions here, I will try to answer them to the best of my abilities. Usually gamma gt is increased in patients with drinking problems or patients with liver diseases. In some cases even patients with hypertension have been known to have high gamma gt levels. While medication has been known to cause an increase in gamma gt levels, I dont believe that the medication you are currently taking has that effect. So what you can do is to talk to your doctor and have him do a liver function test on you, to see whether your liver is functioning properly or not. Once the cause is found and is treated your gamma gt levels should come back down, so talk to your doctor and have your liver checked. I hope this answered your question.
