Hello, I Am A 70 Yo Woman In Generally Good

Question: Hello, I am a 70 yo woman in generally good health. I have mild to moderate asthma and take fluticasone/salmeterol (250/50) inhalation powder once a day. I also use an albuterol rescue inhaler occasionally and flonase in the spring. I also take labetol 100mg a day in divided doses of 50mg. My GFR is around 52 and my physician says that is because I have a long-standing area of calcification in one kidney due to a past history of benign parathyroid adenoma which was removed - the GFR is stable and not deteriorating. I have been getting episodes of sciatica and have been prescribed Percocet to relieve that pain. However, I recently tried CBD oil for the sciatic pain and since it works almost as well as the Percocet I wold rather use it when I have sciatica since Percocet is addicitive. My question is this - is it ok for me to use CBD oil with the other medications I am taking? I'm concerned about whether or not there could be interactions between CBD oil and my other medications. Thank you.
