The alternative medicine may be toxic.
The alternative medicine may interact with standard treatment, such as chemotherapy or medicine that people take for other disorders, thus reducing its effectiveness.
The alternative medicine may be costly, reducing the person’s ability to afford standard treatment.
If alternative medicine is used instead of standard treatment or delays standard treatment, the person will not obtain the proven benefits of standard treatment.
People using alternative medicine should inform their doctor. Hiding the use of alternative medicine could be harmful.
