🌿 Overview
Drug allergies occur when a medication triggers an abnormal immune response in the body. Because drug medications consist of artificially isolated chemicals rather than natural compounds, virtually all pharmaceutical drugs produce side effects in some people. A true drug allergy differs from a side effect — it involves antibody production and immune activation. Allergic reactions can occur the first time a drug is taken or after extended use. They occur most frequently with antibiotics. Once an allergy to a specific drug develops, it is life-long. Some reactions are life-threatening (anaphylaxis). Even non-allergic drug reactions can cause severe harm, including permanent kidney damage.
Common signs
- Wheezing and difficult breathing.
- Swelling anywhere on the body, especially the face and throat.
- Nausea and diarrhea.
- An itchy rash with red, raised areas and sometimes white lumps.
- In severe cases: anaphylactic shock (see Anaphylaxis).
