No withdrawal: in the traditional sense. Antihistamines do not work by the same mechanisms that alcohol or sedatives do, and there is no real tolerance to effects or a stereotypical withdrawal syndrome. Sometimes there is a discontinuation syndrome with anxiety, irritabilty and even electric shock feelings, but it is usually mild and transient. The dose can be gradually reduced over a week or so if worried.
