contraindicada

Contraindicada is the feminine singular form of the adjective contraindicado, used in Spanish and Portuguese. The corresponding English term is contraindicated. The word derives from the prefix contra- “against” and indicar “to indicate.” It is employed to denote that a treatment, drug, procedure, or action should not be used because it could cause harm or be ineffective.

In medical contexts, a contraindication refers to a specific condition or circumstance that makes an intervention inadvisable. The feminine form often accompanies a feminine noun, as in “la administración es contraindicada” or “una contraindicación absoluta.” In Portuguese, the noun is contraindicação and the adjective forms agree in gender.

Contraindications are classified as absolute (or absolute) and relative. Absolute contraindications indicate there are no circumstances under which the intervention should be performed. Relative contraindications require cautious consideration of risks and benefits, sometimes with additional precautions or alternatives.

Common examples include pregnancy with certain medications, severe allergies to a drug, or medical conditions that increase risk during a procedure. Clinicians rely on contraindications in guidelines and patient assessment to minimize harm.
