Several of us here at OCF have reported hiccups related to chemo treatments. Bill had mega hiccups after the first 2 chemos lasting a couple of days. When we finally made the correlation, his MO prescribed,believe it or not, thorazine(chlorpromazine.) He had Bill start this the day before treatment and for a couple of days after....NO MORE HICCUPS. We did not ask why..we just wanted them gone as they were like seizures and kept Bill from resting and sleeping.
When I ask members here if anyone had had the same experience, several people said yes. So, talk to your docs about this.
