side effects of cyclosporin

Hi everyone

I am new to asthma UK but had a question about the side effects of cyclosporin? Have recently been on methotrexate which I could not tolerate they made me as sick as a dog! Also tried Azathioprine. Now my consultant wants me to try Cyclosporin and when you read about the side effects of these group of immuno-surpressents I am wondering whether they are worth the small benefit to my asthma? Any users with any advice greatfully received.

Thanks

Clare
