Question:
Can the goy do a melocho for a sick Jew on shabbos like drive to the pharmacy to get him medicine?
Answer:
Yes. We may ask a gentile to do even melacha d'orayso for a "choleh shein bo sakanah", (a person who is sick, but it isn't life threatening), such as driving to the pharmacy to get him medicine.
Best wishes
