The Peadiatrian has asked me to look into the option of using Vitoza on my son who is 12 almost 13 years old. He is over weight and has Combined Invariable Immune Defiency. Due to the amount of medicine he has taken - his body seems to gone into a 'storage' stage, he had a stomach operation did not eat solids of 6 weeks, but lost no weight. his growth is also very slow. Currently he ways 54 kg. Would you recommend we allow him to use it, and what dosage would you suggest. Thank you for your assistance.
