A doctor's apprentice can write a prescription, and after the doctor signs it, he can buy medical insurance medicine in a pharmacy. According to relevant public information, prescription drugs can only be prepared, purchased and used with the prescriptions of licensed doctors or professional assistant doctors. You only need to buy prescription drugs from the designated social security medical institutions with the doctor's prescription, and you can use the medical insurance card to reimburse (if it is a hospital prescription drug used during hospitalization, it can be reimbursed by medical insurance as a whole).
