Läkemedelsreaktion

Läkemedelsreaktion, also known as adverse drug reaction (ADR), is a harmful and unintended response to a medicinal product. This reaction occurs at doses normally used in humans for the prophylaxis, diagnosis, or therapy of disease, or for the modification of physiological function. Läkemedelsreaktioner can range in severity from mild, such as a rash or nausea, to severe and life-threatening, such as anaphylaxis or organ damage.

The occurrence of a läkemedelsreaktion is influenced by various factors, including the patient's age, genetic makeup, underlying health conditions, and concurrent use of other medications. Additionally, the specific drug involved, its dosage, and the duration of treatment play significant roles. Some läkemedelsreaktioner are predictable and related to the drug's known pharmacological effects, while others are unpredictable and idiosyncratic, meaning they occur rarely and without clear explanation.

Recognizing and reporting läkemedelsreaktioner is crucial for patient safety and the ongoing evaluation of drug efficacy and safety. Healthcare professionals are responsible for monitoring patients for potential adverse effects and reporting suspected reactions to regulatory authorities. Patients are also encouraged to report any unexpected or concerning symptoms they experience while taking medication to their doctor or pharmacist. This information helps in identifying potential risks associated with medications and informing prescribing practices and drug labeling.
