Presence of soluble antigen-antibody complexes (type III reaction). Trigger: Early injection of foreign sera and immunoglobulins. Today: antibiotics, sulphonamides, antiepileptics, X-ray contrast medium, acetylsalicylic acid.

  • Initial exposure: At first exposure, the non-appearance interval is 5-7 days until the first symptoms appear. Glucocorticoids in medium to high dosages such as prednisolone (e.g. Solu Decortin H) 60-100 mg/day or dexamethasone (e.g. Fortecortin Tbl.) 12-16 mg/day. Depending on the clinic, slow dose reduction and balancing.
  • Repeated exposure: Immediate reaction with shock and fulminant course. Raise the patient's legs. Large-lumen i.v. access, possibly central venous valve regimen, rapid volume substitution. Dilute adrenalin (e.g. suprarenin) 1:1000 with 0.9% NaCl solution 1:10 and draw up 10 ml (for pre-filled syringes, no dilution is usually necessary). Slow i.v. injection of 0.3-0.5 ml (-1 ml), repeat after 10 min. Intubation if necessary and possible, otherwise coniotomy or tracheotomy, see shock, more anaphylactic. Glucocorticoids high dosage i.v.: Prednisolone 250-500 mg i.v., if necessary higher dosage and after clinical findings also repeated administration. Depending on the clinical findings, gradual dose reduction and later change to an oral preparation: methylprednisolone (e.g. Urbason) or prednisolone.
    The use of 10 ml calcium gluconate 10% i.v. is controversial, there is no definite indication.
    Heat withdrawal at temperature > 39 °C: calf compress, ice bag in the groin.
