I started taking slow iron about 4 months ago because I'm trying different things to help ween myself off requip. I slowly noticed an improvement in my rls since taking iron. I'm down to 1/4 of my usuall dose of requip most nights. My dr ordered a iron and ferritin level. My ferritin level is 17 after 4 months of 1 iron tablet a day. I asked if I should increase the iron to 2 tables a day she said no continue 1 tablet and she will recheck my ferritin in a year. I am questioning her advice because i think if i can get my ferritin level to normal my rls would be more manageable and I'll be able to finally get off the requip. I usually don't go against dr advice but she is not a rls specialist just a g p . Wondering how much iron other people have taken to increase there ferritin?
