Some good news about pills for a change. For our safety, drug
companies coat some pills with an emetic coating, so that if a
patient, accidentally or otherwise overdoses, the coating will
induce vomiting before the overdose can take effect and
potentially kill the patient.
Another coating is also
used for some chemotherapy medications that will have the
opposite effect and prohibit nausea and vomiting induced by
cytotoxic chemotherapy and radiotherapy. In addition, an
injection of Ondansetron Hydrochloride is sometimes given for
the prevention of post-operative nausea and vomiting.
