Precautions
It is very important that you return to your doctor the next day. This will allow your doctor to see the injected hand, and to do a possible finger extension procedure to disrupt the cord.
This medicine may cause serious types of allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have itching, rash, hives, chest pain, dizziness or lightheadedness, trouble breathing, or any swelling of your hands, face, or mouth after you receive this medicine.
Using this medicine may cause injury to the blood vessels, tendons, or ligaments of the hand. Tell your doctor right away if you have pain or numbness in your hand or arm, trouble bending the finger after the swelling goes down, or bleeding at the injection site.
This medicine may cause infection. Tell your doctor right away if you have a fever, chills, or increasing redness or swelling of your hand.
It is very important that you elevate the fingers of the injected hand until bedtime to prevent swelling. Do not try to move or massage the cord, bend, or extend the fingers of the injected hand, or do heavy activity using your hand to prevent more injury.
Your doctor may put a splint on your hand after giving this medicine. Wear the splint at bedtime for up to 4 months. Do finger bending and extending exercises as instructed by your doctor.
