The instance of celiac disease has spiked in the United States, quadrupling over the last 50 years, according to one estimate.
Most patients respond to the condition by cutting gluten entirely out of their diet, helped by special products and nutrition disclosures that increasingly mention gluten.
But the same is not true for drugs that contain gluten, which pose serious health problems to patients with chronic cases.
"The United States already mandates that food products containing wheat are adequately labeled and there is no reason why we shouldn’t do the same for our medications," Ryan said.
The American Celiac Disease Alliance and several related groups have endorsed the bill.
