My doctor gave me leflunimide and I started it this past week - I took 5 pills for the first three days and then 1 pill each day after. After I took the second single pill, I had a terrible eye reaction, burning and watering, my nose would not stop running. It finally subsided by the end of the day, I thought I would take the pill the next day and the same thing happened. Its s now the 4th of July weekend and I can t get in touch with the doctor. I am not taking this pill again, as this seems to be triggering these symptoms. Have you ever heard of this before? I ve tried to see the side effects of this medicine but it doesn t list what happened to me.
