My son is 9 and about 90% of his body is covered in Psoriasis. We are seeing the Dermotologist tomorrow. However, a couple weeks ago the Nurse Practitioner stated that he could use Methotrexate or something along that lines since he is such a special case. She didn't have the authority to subscribe it, so, we are seeing an actual physician this week. However, I know children are limited to oral medications when it comes to Psoriasis. I just wanted to know if anyone else's kids used Methotrexate and how well they did with it. Any side effects? Feedback would be much appreciated!!
