Fluoxetine (Prozac) is usually prescribed for depression, not anxiety. I would question my doctor about his choice of meds. That is simply my opinion. That he had you Xanax, which IS an antianxiety med makes sense, although I wish he would have made a different choice there as well. Another strong opinion. It's good that he is suggesting you now get off it. Do so ASAP. It should be easy for you to stop since you are taking it prn (as needed) and state that 30 pills last you 3 months. If you later find that you need an antianxiety med, talk to your doctor about diazepam or one of the other long term meds. Valerian root is safe to take with Prozac. The herbs you must avoid with this med are St.John's wort, which can increase the risk of serotonin syndrome, and SAM-e. To avoid an anticholinergic effect, do not use corkwood or jimsonweed. To avoid an increase in CNS effects, avoid hops, kava and lavender.
