Treatment is similar to Anaphylaxis

Patients often report various allergies and there is controversy over the best way to prevent possible<unk> 
Shellfish Allergy
This allergy is specific to shellfish and does not cross react due to the Iodine rich nature of fish and the fish's tropomyosins and parvalbumin
No pretreatment is necessary for shellfish allergies
Iodine
There is no Iodine allergies which are compatible with life due to the existence of iodine in human thyroid tissue and distribution throughout the body
Prior<unk>  Allergies
Pretreatment should not be attempted in these patients since there is a strong association between a prior<unk>  reaction and future anaphylactic<unk>  reactions
Pretreatment with Steroids
There has been no difference found between ionic agents alone versus ionic agents with steroids in preventing allergic reactions.  Non ionic (low osmolality)<unk>  agents are the preferred agent and do reduce the risk of allergic reactions.
