What is the most important information I should know about SUSTOL?
SUSTOL can cause serious side effects, including:
Injection site reactions. Some injection site reactions may be serious and require medical care.

Infections, bruising, and hematomas can happen up to 2 weeks or more after receiving SUSTOL.
Tell your healthcare provider if you have:
ο pain or tenderness that you need to take pain medicine for or if you have pain that interferes with your daily activity.
