Contraindications
Definition of Contraindications
A contraindication is a specific situation in which a drug, procedure, or surgery should NOT be used, because it may be harmful to the patient.
Some treatments may cause unwanted or dangerous reactions in people with allergies, high blood pressure, or pregnancy. For example, certain decongestants are contraindicated in people with high blood pressure and therefore should be avoided.
Many medications interact and should not be used together by the same person. For instance, a person who takes warfarin to thin the blood should not take aspirin.
There are two types of contraindications:
- Relative contraindication means that caution should be used when two drugs or procedures are used together. (It is acceptable to do so if the benefits outweigh the risk.)
- Absolute contraindication means that it could result in a life-threatening situation. A procedure or medication that falls under this category should be avoided.
