The following describes the Contraindication type that is currently being implemented. 

Overview:

The contraindication type is used to store substances (such as drugs or foods) that interact badly with your condition or medications that you are already taking.

Examples of this are:

·         Grapefruit juice can deactivate blood pressure medication

·         Any food with large amounts of vitamin K interferes  with anticoagulation drugs

·         Alcohol has interaction with many drugs

·         Many herbal remedies have drug interactions

·         People taking Digoxin should avoid black licorice

Contraindication is different from allergy in the patient reaction to the substance.  Allergies are about substances that cause a reaction for a patient, while contraindication is about issues that arise because the patient is on a specific medication.

 Data elements:

• Substance (CodableValue) - The substance that is contraindicated
• Source (CodableValue) - The drug/condition that leads to the contraindication
• DocumentedBy (Person) - Who documented the issue (physician, pharmacist, etc.)
