Although it is wise to be cautious when administering more than one dr
ug to a patient, polypharmacy is not a controversial practice. Rather,
it is a useful and an accepted method of treating complicated cases i
n all medical specialities. There is a need for more rigorous study of
multiple-medication therapies. However, physicians must be able to ma
ke decisions based on the data that are available and not be limited i
n their ability to treat a patient by a lack of scientific validation
for every aspect of the treatment.
