A frequently encountered complication of therapy given to patients with severe haemophilia A is the development of antibodies to infused factor VIII. While much less common, inhibitors also occur in patients with mild or moderate severity haemophilia A. Often thought to be of low titre and transient, several cases of high‐titre inhibitors have been described in patients with mild or moderate haemophilia A. Generally these occur in adults or adolescents following significant infused factor VIII exposure. A review of reported cases revealed only two cases of high‐titre inhibitor formation in mild haemophilia A patients younger than 10 years of age. We wish to report our experience with an additional two children with mild haemophilia A and high titre inhibitors, and offer suggestions for the management of these children.
