Introduction: Jellyfish stings are common injuries for tourists visiting the German coasts and regularly require consultations from the regional lifeguard service. Objectives: This review aims to summarize the evidence for the various therapeutic options for treating jellyfish stings. Method: We performed a selective literature research in the medical database PubMed with the search terms „jellyfish treatment“,„Rasierschaum“, „shaving foam“ and „shaving lather“. Based on the reference lists, additional references were identified and included. The recommendations of this review are classified by levels of evidence and grades of recommendation according to the CEBM classification of evidence. Results: Experimental studies show that the complaints after jellyfish stings from Cyanea capillata can be strengthened by the application of vinegar. Warmth or cold are able to relieve the symptoms. For most other common treatment methods, no strong scientific evidence is available. Discussion: After a jellyfish sting, one should leave the water and visible remains of jellyfish tissue should be removed mechanically. The jellyfish sting can be treated with local application of warmth or cold, shaving foam, antihistamines or cortisone. Vinegar should not be used. An expired tetanus vaccination should be refreshed. Haemolysis can be treated by application of calcium channel blockers or antioxidants.
