Yes, I am just a little aware of the sun & its affects & am a little religious about my covering up (even biking & running). And so, my little fishies in the summer time, are also in their long sleeve rash guards with glowing white faces due to sunscreen.
But today her pediatrician asked a pertinent question: "The reaction was only on her neck & face? Then that's not a sunscreen reaction or it would be everywhere you had applied sunscreen."
Addison is on a drug for her arthritis called Methotrexate. The pediatrician clued into this & it was an "AHA!" because taking methotrexate can cause "sun-sensitivity." And it truly did with Addison in a bad reaction sorta way during their vacation in Texas where the sun is MORE than intense, its just plain HOT down there!
Charlotte & Addison take Methotrexate at home, once a week, thru a shot given by us! In our case, we are now giving Charlotte her Methotrexate orally, but its the same "stuff." Methotrexate interferes with the growth of certain cells of the body, especially cells that reproduce quickly, such as cancer cells, bone marrow cells, and skin cells.
Methotrexate is used to treat certain types of cancer of the breast, skin, head and neck, or lung. Methotrexate is also used to treat severe psoriasis and rheumatoid arthritis.
In the Arthritis world, Methotrexate is the go-to drug. Its very common that most all the JRA children we know are on MTX (abbreviated) or have been at one time or another & now are weened off due to successful body response.
