Detailed Answer:
HI, thanks for using healthcare magic
I am sorry that your father is currently unwell.
Dilaudid is the trade name for
hydromorphone which is in the opiate family of pain killers.
This class of drugs can cause nausea with consequent reduction in appetite. Constipation is also a well known possible side effect of this class of medications.
You are right in assuming that the use of an antiemetic such as gravol would be helpful. The only issue would be increased
drowsiness which is a side effect of gravol and also of his pain medications.
You would have to try the lower dose of 50 mg and see if it helps.
There are other antiemetics that work differently such as (1)
metoclopramide, this is a prokinetic agent (increases movement in bowel).
(2)
antipsychotic medications are also used for their antiemetic effect
In terms of the constipation,as mentioned it may also be a side effect but may also be related to his decreased diet as you suggested.
Treatment , in addition to the
milk of magnesia he is currently using, would entail increasing his fluid and fiber intake once the nausea decreases.
If the milk of magnesia is not effective there are other options such as senna, fibercon,citrucel or
metamucil.
I hope this helps , feel free to ask any other questions
