Alimemazine

Översikt

What is alimemazine used for?

Alimemazine is a type of antihistamine used to relieve lumpy and itchy allergic skin reactions called hives (urticaria). It is also used before surgical procedures to help keep young children calm.

When alimemazine is prescribed for a young child who is about to have an operation, it produces a sedative effect which helps the child feel relaxed. Alimemazine is not suitable for children under 2 years of age.

How does alimemazine work?

Alimemazine works by blocking a substance called histamine in the body. In some people, an excess of histamine is produced by exposure to substances such as pollen, pet fur, house dust or insect bites, and this causes allergic skin reactions.

By blocking histamine, alimemazine eases the itchiness and lumpiness of these reactions.
