A physician who deals with a patient who has described all the symptoms of his or her problem, may decide to prescribe drug treatment. The physician has to choose a drug that provides the powerful help.
The treatment have to be effective in treating pain and infection as well as general condition. The compability and combination of drugs has to be ensured. A physician may have to use the "trial and error" approach with certain drugs if the symptoms show one of many possible causes.
The physician has to consider side effects of drug treatment. A patient should be warned about the side effects caused by some drugs. They can be different to comparetively minor effects. The role of side effects is especially serious in chemotherapy techniques, in which internal tumors are effectively overwhelmed with drugs. Therefore a physician has to monitor a patient's reaction to a drug is necessary.
Before the physician gives the prescribed drugs to the patient he/she has to make sure that the condition has been diagnosed correctly. The patient's diagnosis must take into account exactly what and where the symptoms are, because the pain can be "refered" from one place in the body to another. A physician has to prescribe a course of "dummy" pills to a patient which are realistic fakes that may fool the patient but which have no clinical effect. They are now believed to have some slight effect.
In urban areas a physician has to
be certain before completing a prescription
for a drug that the prescribed
drug will produce no allergic effects. A
physician has to watch carefully
in diagnosis when prescribing drugs that could be abused. He has to be
careful because the offered usage of certain drugs could encourage addiction.
