Analgesic intolerance; Intolerance to painkillers
DefinitionThis section has been translated automatically.
Intolerance reactions due to analgesics, especially non-steroidal anti-inflammatory drugs. Aspirin triggers 3/4 of analgesic intolerance. For acetylsalicylic acid, sophisticated allergological test methods are available (inhalative, intranasal, oral). Other agents are frequently prescribed, but the test procedures are not standardised.
- Scratch test: Production of a saturated suspension with 0.9% NaCl from the pure substances. Scarification of an area measuring 2 × 2 cm using a scalpel on the inside of the forearm. Application of the suspension for 20 minutes. Positive reactions show an increased urticarial component compared to pure 0.9% NaCl solution. Positive control with histamine hydrochloride 0.1% in 0.9% NaCl solution.
- Severe symptoms of intolerance are distributed per drug as follows:
- Metamizole (no anaphylactoid reaction)
- carbamazepine (no anaphylactoid reaction, only cutaneous symptoms, of which 50% are erythema exsudativa multiforme)
- Propyphenazone (30% anaphylactoid reactions, bronchial reactions)
- Diclofenac
- Ibuprofen: cutaneous symptoms (exanthema, urticaria, quincke oedema).
