Pacific Sea Nettle stings rarely require medical attention, despite causing considerable pain and discomfort. However, at least one case of severe reaction has been attributed to multiple stings from this species (Burnett 2006). In recent years, laboratory and field trials of a commercially developed sting inhibitor have shown excellent promise in reducing both the frequency and severity of stings from Pacific Sea Nettlles, as well as some more dangerous jellyfish (Kimball et al. 2004; Boulware 2006). This product is reportedly based at least in part on the chemical properties of the mucus coating of clownfish (Boulware 2006), which protects the clownfish from the stings of the sea anemones with which they are closely associated.
