Received request from ZZZ hub to apply dry ice supplemental procedures after crew had signed release and headed to aircraft but before they had initialized ACARS. Approved the request with intent to notify crew and amend release once they were on the aircraft. During this time frame; got busy with other releases and departing flights with payload increases; alternate changes; etc. Forgot to get back to [Aircraft X] until after aircraft was airborne and on the way to ZZZ1.This event was caused due to simply had too much going on at one time. I had even put a flag on the flight as a reminder but still got tied up. Dispatcher suggests reducing the domestic flight desk workload.
Air Carrier Dispatcher reported a Hazmat transport procedure violation due to inadequate staffing for the high departure workload.
