What happens if I stop taking guaifenesin after I have no more symptoms?
Guaifenesin is not a cure for FMS and will work only while you are taking it, like all medications that control something, like blood pressure, or blood sugar, or thyroid medications. If you stop taking it when you are controlled, you will no longer be controlled. The phosphates will build back up, and your FMS will come back. However, some people, once they are cleared out, can stop the guaifenesin, and it comes back very slowly, or may come back later in life. These people had borderline symptoms and maybe an accident tipped them into it. They’re like someone who can quit blood pressure medications after losing weight, but they have the gene, and any stress will bring it back. In this group, we are by and large, people who have had FMS all our lives, badly, and we are the kind who would need to take the medication forever.
