Medicament delivery device with usage monitoring

A medicament delivery device comprising

• a housing constructed to accommodate a medicament container;
• a drive unit configured to operably act on the medicament container upon activation;
• an activation mechanism configured for operation by a user;
• an activation preventing mechanism operably configured that prevents a user from activating the activation mechanism;
• a usage management module configured for operation by a user, where the usage management module is attachable to the medicament delivery device;
• and
• first keying elements arranged on the medicament delivery device and on the usage management module that interact with each other when the usage management module is attached to the medicament delivery device, where the attachment causes deactivation of the activation preventing mechanism and allowing operation of the activation mechanism, where
• the usage management module comprises a monitoring circuit that monitors the use of the medicament delivery device.
