contraindication

noun

con·​tra·​in·​di·​ca·​tion ˌkän-trə-ˌin-də-ˈkā-shən 

: something (such as a symptom or condition) that makes a particular treatment or procedure inadvisable

Did you know?

For doctors, an indication is a symptom or circumstance that makes a particular medical treatment desirable. Serious anxiety, for example, is often an indication for prescribing a tranquilizer. A contraindication, then, is a symptom or condition that makes a treatment risky, such as taking certain other medications at the same time. Drugs and conditions that are contraindicated for a medication are listed on its label, and reeled off at high speed in TV ads. Patients can guard against the dangers of drug interaction by reading labels carefully and making sure their doctors know what else they're currently taking.
