This study is for those people with difficult to treat hives. We are investigating whether or
not a different medication, hydroxychloroquine, works to treat a certain type of hives.
Hydrochloroquine is currently approved by the Food and Drug Administration (FDA), for
treating arthritis, therefore it is considered investigational in this study.
Hypothesis: Hydroxychloroquine will prove to have an efficacious response in terms of
Urticarial Symptoms, on patients with chronic urticaria.
