A method to reduce or stop a response such as an allergic reaction to something. For instance, if a person with diabetes has a bad reaction to taking a full dose of beef insulin, the doctor gives the person a very small amount of the insulin at first. Over a period of time, larger doses are given until the person is taking the full dose. This is one way to help the body get used to the full dose and to avoid having the allergic reaction.
