- Don’t take acetaminophen (Tylenol®) or ibuprofen (Advil® or Motrin®) to relieve pain unless instructed by your healthcare provider.
- Take pain medication only as prescribed. If the medication isn’t helping your pain or if you’re having any side effects (such as constipation, nausea, fatigue, or itching) from the medication, call your doctor.

You may have an allergic reaction to 3F8 immunotherapy treatment in the form of hives, redness, or swelling. These reactions can happen at any time between treatments. Your healthcare provider may prescribe you medication to help with this.
Things to remember:
- To prepare for any allergic reaction you may have after discharge, make sure you have the medication your healthcare provider prescribed to you, such as hydroxyzine (Vistaril®) or diphenhydramine (Benadryl®), before you leave the hospital.

A central line, or central venous catheter, is like an artificial vein. It will make it easier for your healthcare team to access your blood vessels for medications and tests. Central lines can collect bacteria and cause infection. If you have a central line and have a fever of 100.4° F (38 ° C) or higher, or you have redness, swelling, or tenderness at the catheter site, call your doctor as soon as possible.
Does your child have a central line (MediPort®, Broviac®, PICC)? YES / NO
