Sulfasalazine didnt work for me!

hi all
yes doodle dame,, i had the same prob , but couldnt work out why!
then wife asked me if i had cleened my teeth, yes i replyed well didnt think any more about it ,then started to get worse .so i got bottle of spermint mouthwash that seemed to help. (thankfully)
wasnt on it for long tho it my doctor phoned me on 3week in and told me to stop taking .(lowered my white blood count)
(on met now so far so good.) mike.
