Thorazine ( Chlorpromazine):
Chlorpromazine is an anti-psychotic medication in a group of drugs called phenothiazines (FEEN-oh-THYE-a-zeens). It works by changing the actions of chemicals in your brain.
Chlorpromazine is used to treat psychotic disorders such as schizophrenia or manic-depression, and severe behavioral problems in children. It is also used to treat nausea and vomiting, anxiety before surgery, chronic hiccups, acute intermittent porphyria, and symptoms of tetanus.
While Thorazine is "sometimes" given to treat chronic hiccups, it should not be the physician's first choice because of it's side-effects and chemical alterations of the brain... Furthermore, vaping is not known to CAUSE chronic hiccups in vapers....
Hiccups are caused by the irritation of the Phrenic Nerve (which regulates the diaphragm, and breathing). If vaping is causing hiccups, it could be an allergic reaction to something in the vapor, which leads me to ask... WHAT IS HE VAPING?
