When you take enbrel, you are more susceptible to infections, especially sinus infections. I also had trouble with it early on, when I first started taking enbrel. If you have a sinus infection, you will need to get antibiotics to treat it. and you will need to stop taking the enbrel until you finish up the antibiotics. After a while, my body adjusted to the enbrel, and I stopped getting so many sinus infections. I also started taking mtx with it, and my rheumy told me that mtx actually has a protective factor when it comes to the common cold, etc... I haven't had a major cold yet, since I've been on the mtx.
