I agree with the above advice to make sure you don't have a sinus infection. I got so many infections towards the end, and for the first couple months after, treatment.
Wonder if you've recently changed from air conditioning to heating, depending on where you are in California. My nose often runs temporarily when I switch the systems over. Running clear is usually an allergic reaction and can be caused by the heating.
Your immune system may not yet be up to speed so it's still wise to stay on top of anything you may catch. I started to get hayfever a couple of weeks ago (on tx), and found a 'saline rinse' bottle with pre-dose saline solution (obtained from the chemist) cleared it quickly. (I had similar a couple of years ago which turned into a nasty cold and chest infection, so whether you see a doctor, get cold/flu/allergy tabs or use a saline rinse, it would pay to try to control it)....
I don't know whether it's anything to do with the meds but I suspect your body is perhaps still vulnerable.
