psoriatic arthritis
"I was recently diagnosed with psoriatic arthritis at the age of 45.  Very early stages according to my doctor.  He placed me on Sulfasalazine.  Started 1 pill per day for 2 weeks then 2 a day the next week then 3x per day the following week.  When I made it to the 3x per day I had a terrible reaction.  Severe nausea, headaches, and sensitivity to light and noticed I felt weak and was  about to go to the emergency room.  I stopped immediately and felt better within days.  I'm diabetic and tested my blood sugar and did notice a massive drop on this medication. The symptoms I was having could have been low blood sugar.  The sulfasalazine may have reacted to my metformin to cause low blood sugar.  I was switched to Plaquenil."
