I was on injectable methorexate for a couple of years b/c I developed stomach ulcers from the oral. I did have trouble at first with the thought of injecting myself, but after the first couple of times I did get used to it (I did it in my thigh). Let me assure you, it wasn't too bad once you get used to it. (I hated needles too!)
To answer your other question, I think the injectable was fairly inexpensive if I remeber correctly (under $20- before insurance). It has been several years since I have taken it, but when I get a chance I can go back and check my records to see how much it was. Another suggestion if you don't have insurance is having rxs filled at a pharmacy like Sam's. Some medications they won't carry, but it's worth trying... I use them when one of my dogs needs a human drug. The price difference is amazing if you use a discount warehouse. I don't know if Costco has a pharmacy or not?
As far as side effects, I experienced the same side effects as the oral- (nausea, feeling tired and I did have minor hair loss), except it didn't destroy my stomach lining.
I hope this helps, and I can get back to you about the price, if you haven't found out already... just let me know!
