Emergency Medical Minute Podcast # 471: Cyclic Vomiting
Author: Don Stader, MD
Educational Pearls:
- Cyclic vomiting syndrome (CVS) is different than cannabis hyperemesis syndrome (CHS). It is important to differentiate the two.
- CHS is thought to be caused by activation of THC receptors in the gut
- CVS is associated with migraines and therefore responds to similar medications
- Olanzapine (Zyprexa) is an alternative to haloperidol (Haldol)
- Amitriptyline, as well as anti-epileptics can be used to prevent CVS
- Opioids worsen CVS
