Hi defuni,

Welcome to the forum! I have never taken Oxtellar XR but I have
taken Trileptal in the past and this drug is a lot like trileptal. I will tell you while on this drug you must stay away from grapefruit and grapefruit juice because the enzymes in the fruit will mess up the med also be careful if you have to take any antibiotics because antibiotics can cause this drug to be toxic.
I haven't heard of a starter kit for this drug you might want to check with your pharmacist to get the best info. I've found they know much more about meds than any Dr. I've ever dealt with.
To find which AED (sz. med) works the best get a DNA test done and the lab can match up the enzymes and chemicals in your body to the best AED to take with the least side effect. I wish you the best of luck and May God Bless You!
