<<Disclaimer: Verify this information before applying it to your situation.>> (Disclaimer-This is not medical advise.) 1) I have found that taking Motrin (ibuprofen) can relieve a lot of the gastrointestinal symptoms from an inadvertant gluten ingestion. 2) According to the medical literature, corticosteroids stop this type of immune response, so if your physician will prescribe a single dose of corisone (or prednisone) for this type of reaction, it should help a lot with the symptoms. Of course, you should not take steriods for long periods of time to avoid supression of your own adrenals.
