Hi Alec1, my son started Remicade last year in May, he was 16 at the time. He felt the benefits right away, it was a complete 180 from all of the symptoms he had been experiencing for some months.
Unfortunately, once we got past the loading doses he couldn't make the 8 week stretch without some symptoms starting to come back. The doc shortened the schedule, upped the dose and finally we added methotrexate. Things are going good right now.
He has no side effects from the Remicade, if they give him benedryl before his infusion it can make him sleepy afterward and he might take an hour nap on the drive home.
He has his infusion at the GI's IV lab so there are 8 or 10 recliners for the patients, they have a flat screen, xbox, wii and movies, you can also bring a movie, they have wifi so he brings his laptop sometimes. In the beginning, the infusion lasted about 3.5 hours but they have sped up the drip to 2 to 2.5 hours. The nurses provide snacks and drinks during the infusion. He isn't bothered by the IV and sometimes brings his school work to pass the time and stay caught up.
Hope all goes well at your appointment.
