As the others posted, 6MP is prescribed somewhat by your daughter's weight, but it will also be decided by how she is tolerating the medication and how her liver is metabolizing it. That is one of the reasons for all the blood work. The original dose should be weight based. Then the blood work starts. At some point you should ask to have the blood sent to Prometheus to check for the therapeutic levels as well as the toxic levels. They are the only lab that can do the therapeutic levels. If your daughter isn't at the therapeutic level yet, then the dose can be increased if the toxic levels are OK. And if the toxic levels are too high, but she is in the therapeutic levels, they can lower the dose. It is all a bit of a game in the beginning. I have been on doses as high as 150mg and as low as my current dose of 50mg within the span of about 12 years. Just make sure that you keep up with blood work and request to have it sent to Prometheus occasionally, but get prior approval from your insurance for that one!
