nausea/vomiting
"Haldol was given to my mother for nausea/vomiting in her final days/weeks of battling colon cancer. Haldol worked great for nausea but the side effects were horrible. She was not drowsy, she was out! Not coherent, confused, wasn't able to eat and at times was agitated. Be very careful using this medication. It took two days after stopping the medication for it to leave her system and return to a normal state of mind."
