Proper Use
A doctor or other trained health professional will give your child this medicine in a hospital. It is given through an IV catheter that is placed in a vein. This medicine must be given slowly, so the IV will need to stay in place for at least 30 minutes.
This medicine is made specifically for each patient, using the patient's own blood cells. Your child's doctor will collect your child's blood through a procedure called mobilization and apheresis. Talk with your child's doctor if you have any concerns about this.
Your child should not use medicine to treat HIV for at least 1 month before having a procedure to collect his or her blood.
Precautions
It is very important that your child's doctor check your child's progress at regular visits to make sure that this medicine is working properly. Blood tests are needed to check for unwanted effects.
The doctor may do tests to make sure your adolescent is not pregnant before having a procedure to collect blood. Female patients and male patients with female partners should use an effective form of birth control before having a procedure to collect blood and for at least 6 months after the last dose.

Check with your child's doctor right away if your child has pain in the chest, groin, or legs, especially the calves, severe headache, slurred speech, sudden, unexplained trouble breathing, sudden loss of coordination, sudden, severe weakness or numbness in the arm or leg, tenderness, pain, swelling, warmth, skin discoloration, and prominent superficial veins over affected area, or vision changes.

Atidarsagene autotemcel will lower the number of some types of blood cells in your child's body. Because of this, your child may bleed or get infections more easily. To help with these problems, avoid being near people who are sick or have infections. Wash your and your child's hands often. Stay away from rough sports or other situations where your child could be bruised, cut, or injured. Tell your child to brush and floss teeth gently. Your child should be careful when using sharp objects, including razors and fingernail clippers. Call your child's doctor right away if your child has fever, chills, or any signs or symptoms of an infection.

This medicine may cause serious allergic reaction, including anaphylaxis, which may be life-threatening and requires immediate medical attention. Check with your child's doctor right away if your child has a rash, itching, dizziness, fainting, fast heartbeat, trouble breathing or swallowing, or chest tightness while using this medicine.
