i always suggest you have your prescriptions filled at the same pharmacy so that the pharmacist can screen each prescription you get for drug interactions with your other medications. in this case i do not notice any significant interactions between the medications you listed. adipex and the "d" part of claritin-d have similar side effects and can be stimulating. so taking the two together may cause insomnia jitters and a rapid heartbeat. if you notice any of these occurring you should talk to your health care professional.
i have been prescribed medications by two doctors. are they all safe to take together? . these medicines include singulair 10 mg 1x/day prednisone 40 mg 1x/day flonase adipex claritin-d 24 hour and lansoprazole dr 30 bid.
