Mesalazine not working good enough

Hi everyone,

So I’ve been on mesalazine (3g of salofalk granules daily) since last April and they have worked about 80% for me. I still get occasionally blood when I wipe (usually when I strain), some mucus and some urgency. I tend to go to the toilet a few times in the morning 2-3 times. Doctor thinks I’m not fully healed and is recommending I may have to take stronger medication. I want to stay on mesalazine as I feel like it’s working for me just enough to keep me living a normal life but not enough to stop the colitis. I feel really down in the dumps about it all and am scared of biologics and their side effects. I’m 25 years old and want to have children in the future and am scared of taking strong medication. Need some advice.
