Ustekinumab biologic injection

Hi all Just jumped back on the forum, have not been on here for a year or more. The reason I have jumped on is because I have just started on Ustekinumab 45mg injections and wanted to find out how others are finding it if using them. I have just done my second injection and the results have been really good with my skin calming right down, no itching no flaky patches. I did go through a couple of months on Methotrexate about a year ago, but it was wiping me out so I had to stop it. The one thing I'm keen to find out is does Ustekinumab cause any fatigue, at the moment I'm feeling very tired all the time. I'm not sure if this is the medication or other stress factors at play. kind regards Colin
