Fumaderm and kidney problems

[krug22]

Finally  got hold of dermo today. Basically he wants to refer Eric for injections - did not say which ones, at the hospital but in the meantime, he is to go back onto Acitretin which he was on early last year. It did not control the psoriasis which was why they tried Eric on Ciclosporin and then Fumaderm. Thankfully we have some left over until I can arrange to collect the prescription from the hospital.
He has not had a flare up yet so the Acitretin may just keep the psoriasis under control - we have an appointment on 22nd April and we will keep this unless we get an appointment for the injections through in the meantime. In a way, I hope we do not, as I would like to ask a few questions first. 
I would imagine the letter will give details of what the injection comprises on but would really appreciate feedback from anyone on injections. I was told last year that it would be a last resort if the Fumaderm did not work.
I do not think Eric will refuse injections although I do not think he will be very happy! He also has Lupus and it is very important we control this.
He literally could not walk this time last year plus he had infections due to the sores so we have to go for the injections I feel.
I cannot research until I know what he is going to be put on but I gathered from my initial conversation that it is regular visits for several weeks or even months.
Thanks for listening - very out of my depth frankly but you are a lovely group of people.
