For people with celiac disease or gluten intolerance, avoiding gluten is important but difficult as even small amounts can cause problems. While obvious gluten foods like bread and pasta are easy to avoid, it can be harder to avoid drugs that may contain trace amounts of gluten as fillers, coatings, or from cross-contamination in manufacturing. However, increased awareness of celiac disease has led more companies to produce gluten-free ingredients and label products as such. It is best to contact manufacturers to confirm medications are gluten-free since ingredients and processes can change.
