מתן תרופות עם תופעות לוואי של מוות

I am psychiatric resident in New York, USA at Long Island Jewish Medical Center. . One of my

supervisor is a Physician asked me if I

could do research on the following question: What is the Jewish perspective on Prescribing medications for a non-fatal condition that one of its known side effects is death. For example, there is a

condition called irritable bowel syndrome, which a person afflicted with this disease constantly has either constipation or diarrhea.

There is a medication called alosetron that is prescribed to treat this condition in which 1 in 10,000 who take the medication die from

the actual medication. Do physicians have the right to prescribe such a medication. Does the concept of ( I'm not good at writing

Aramiac with english letter) minority or minority of a minority

apply in such a case. Can you refer med to articles that

deal with

this question. Would the halacah be different in the following situation: The incidence of suicide is significantly higher in

people with schizophrenia.There are medications prescribed for

schizophrenia which can decrease the number of white blood cells and

lead to death by means of infection. 1 in 10,000 who take the

medication die from this side effect. Here the medication is

treating a condition which possibly can lead to death, i.e. suicide.

Thank you
