Hi Ezza - welcome!
I have been prescribed Plaquenil and started it on the 26.2.14 i find the only side effect i have so far is passing alot of wind.
You will find that medicines affect different people, different ways. For myself, I found that when I take Plaquenil with milk (in the morning for breakfast) that I have a lot of gassiness. If I take it without milk, I'm fine. There have been other members on this forum that said the same thing, that milk w/Plaquenil caused them gassiness. It's kinda of odd, as on the directions it says to be taken with milk or food. I just know what works for me.
There is a wealth of information here on the forum. If there is a specific topic you are interested in, if you put that word(s) in the subject box to the top right of this page, it will take you to previous threads about that topic. Of course, by all means, you can start your own thread.
We're a very diverse group here . . we range in age from teenagers to people into their 80's and everywhere in between. With this forum, it's nice to be able to relate to others who share the daily challenges of having an autoimmune disease called Sjogren's Syndrome.
There are several helpful books on the market about Sjogren's Syndrome too.
Again, welcome . . I hope you find this site helpful to you on your Sjogren's journey . . . when you come here, please know that "we get it"!
