This is a question for your Dr.
But, 2 weeks isnt very long to be on a medication. But no matter how long or short im on a med, i always wean just to be safe. Some Drs say you'll be fine... but I don't take that chance of cold turkey. What I do, and I'm not giving medical advice,... but I'll take half of what I'm taking for about a week, then a cut that half in half, for a week, then just a little bit for a week, then done. Works pretty good for me. =)
