Hello, my nephew is 16 and has been taking acutane which finally helped with acne but took almost 5 months to see good results. Now my sis is telling me how he is severely tired, can't stay awake, and has no energy. I told her that he has been that way to me for awhile even possibly before the acutane. When the doc put him on it, they did not test his testerone level and was mostly concerned with his liver and kidney levels;which I think that they tested what was to be expected at that time. This kid can not gain weight to save his soul; and has not been able to for his entire life. My sis thinks it is totally linked to the acutane which might be but I am not sold on this. I think it could be two different issues, but am looking for advice to give her. When she finally took him to doc, his testerone levels were very low for his age and they are now on list to get into a pediatric endocrinologist (only the good lord knows how long this will take). ( I might add that she has tried to get him into one for several years as he is much smaller then all of his friends and she has said no one will listen.) Open to advice and suggestions, they live in Oklahoma which is almost the hell-hole for any kind of medicaltreatment options.
