Contraindication is a specific situation in which a drug, procedure, or surgery should not be used because it may be harmful to the person. There are two types of contraindications:
(1) Relative contraindication means that caution should be used when two drugs or procedures are used together.
(2) Absolute contraindication means that event or substance could cause a life-threatening situation. A procedure or medicine that falls under this category must be avoided.
Those diagnosed with ASD have comorbid and overlapping conditions. Many may be polypharmacy and cautionary methods are needed to avoid contraindication.
