Your healthcare provider will monitor you for these complications.
Getting medical treatment right away may help keep these problems from becoming more serious.
Your healthcare provider will check you for these problems during treatment with LOQTORZI™. Your healthcare provider may treat you with corticosteroid or hormone replacement medicines. Your healthcare provider may also need to delay or completely stop treatment with LOQTORZI™ if you have severe side effects.

Tell your health care provider right away if you think you may be pregnant or you become pregnant during treatment with LOQTORZI™
