What do contraindications mean


from Latin: contra - against and indicare - to indicate
Synonym: contraindication

1 definition

A Contraindication is a factor (e.g. age, certain previous illnesses, injuries etc., but also conditions such as pregnancy) that speaks against a certain diagnostic or therapeutic measure (e.g. the administration of a drug). If a contraindication is ignored, damage to an (organ) system or worsening of an existing underlying disease can result.

2 classification

  • Absolute contraindication: The planned measure must be dispensed with here, as its negative effects on the patient would be too serious.
  • Relative contraindication: The planned measure can be carried out if the expected benefit outweighs the damage to be feared. To do this, the doctor must carefully weigh up the risk-benefit ratio of the measure beforehand.

3.2 Relative contraindications

Pregnancy is relatively often a contraindication because many drugs must not be taken or used during pregnancy in order to avoid harm to the child during pregnancy and / or during the birth phase.
