lääkereaktio

Lääkereaktio, often translated as drug reaction or adverse drug reaction (ADR), refers to an unintended and harmful response to a medication. This response can occur at any dose and is distinct from an overdose. Lääkereaktiot range from mild, such as a skin rash or nausea, to severe and life-threatening, including anaphylaxis or organ damage.

The causes of lääkereaktio are varied. They can be due to the drug's inherent properties, such as its mechanism of action or metabolism, leading to expected but undesirable side effects. Alternatively, they can be idiosyncratic, meaning they are unpredictable and not related to the drug's usual pharmacological effects. Factors like patient genetics, age, other medical conditions, and interactions with other medications can also influence the likelihood and severity of a lääkereaktio.

Identifying and reporting lääkereaktiot is crucial for patient safety. Healthcare professionals play a key role in monitoring patients for potential reactions, diagnosing them, and adjusting treatment accordingly. Patients are encouraged to report any unusual or concerning symptoms they experience after starting a new medication to their doctor or pharmacist. This information helps in understanding drug safety profiles and improving prescribing practices. Prevention strategies include careful prescribing, patient education, and monitoring for drug interactions.
