Over time your hives might spontaneously improve so if you have been well controlled for a while now, might be worth attempting a trial wean to see if the hives come back.

Immune-suppressing meds like Cyclosporine can help chronic cases, but also have side effects that must be weighed against the benefits. Some cases respond to a medication used to treat allergic asthma. See an allergist for more info. ...Read moreSee 1 more doctor answer
