CYC stands for Cyclophosphamide, a drug abbreviation.

Abbreviation preferred in rheumatology and nephrology for cyclophosphamide used to treat severe autoimmune conditions such as lupus nephritis and ANCA-associated vasculitis.

Example: Euro-Lupus protocol: CYC 500 mg IV every 2 weeks x 6 doses.

Usage notes

Low-dose "Euro-Lupus" regimens produce fewer side effects than older high-dose monthly regimens. Cumulative lifetime dose matters because the risk of bladder cancer and infertility increases with total exposure. Rituximab has replaced cyclophosphamide for many vasculitis patients.
