my dd16 has been taking humira for 2 yrs with pretty good results - she eats a low fodmap diet and had surgery 2 &1/2 yrs ago. things started going downhill about 2 or 3 months ago. We just had her humira levels tested and they are too low so they are upping her dose to weekly . why does this happen and what will change side effect wise - does anyone know if the the fact that I would have to chase her down and remind her for days some times to take her shot - often she wold be 2 or 3 days late with it .... could this have caused the problem?
