Drug allergies

Alternative Names: Allergic reaction - drug (medication) Symptoms: Hives (common) Skin rash (common) Itching of the skin or eyes (common) Wheezing Swelling of the lips, tongue, or face Anaphylaxis, or severe allergic reaction (see below) Symptoms of anaphylaxis include: Difficulty breathing with wheeze or hoarse voice Hives over different parts of the body Fainting, light-headedness Dizziness Confusion Rapid pulse Sensation of feeling the heart beat (palpitations) Nausea, vomiting Diarrhea Abdominal pain or cramping Signs and tests: Text Continues Below An examination of the skin and face may show hives, rash, or angioedema (swelling of the lips, face, or tongue). Decreased blood pressure, wheezing, and other signs may indicate an anaphylactic reaction. Skin testing may confirm allergy to penicillin-type medications. Testing may be ineffective (or in some cases, dangerous) for other medications. A history of allergic-type reaction after use of a medication is often considered proof enough of drug allergy -- no further testing is required. The same applies to other substances that are not considered drugs but are used in hospitals, such as x-ray contrast dyes.
