There is a great deal of debate as to whether gluten should be avoided by all people or just those with gluten intolerance. While some people may choose a gluten-free diet because they believe gluten is bad for them, a person with gluten intolerance must follow this diet to avoid an adverse reaction. There are varying degrees of sensitivity to gluten in people who suffer from gluten intolerance.
The most severe form of gluten intolerance is celiac disease. People with celiac disease will want to adhere to a strict gluten-free diet, including the avoidance of gluten in their medications. The Celiac Disease Foundation website https://celiac.org/celiac-disease/what-is-celiac-disease/ is a great place to learn more about celiac disease.
Whether a gluten-free diet is followed by choice or because of gluten intolerance, people on this diet ought to know if the medications they are taking contain gluten. Since Effer-K does not contain gluten, it is safe to take on a gluten-free diet.
