Sunbeds and acitretin

Hi everyone have been taking aciterin for just over 2 months now. My skin has improved my guatte is not going really flakey anymore I am just covered in red patches where my psoriasis was. Does anyone know if I can use a sunbed at the same time as taking this medication? I am looking to do 2 min sessions twice a week. Just don't know if I should. I am taking 30mg a day. Thanks for any help.
