My husband was diagnosed with Rheumatoid Arthritis in August 2002 after over a year and a half of joint problems. His RA factor (a blood marker for arthritis) was 104. God revealed to me the word Dilantin. My husband had been on Dilantin for 20 years. I got on the Internet and found posts of people on another epilepsy board who had joint problems, lupus, etc. We saw a rheumatologist who confirmed what we believed, that his RA was Dilantin-induced. Other doctors had not thought it possible, esp. his neurologist. Fortunately, it had been 9 years since his last seizure and he was able to go off Dilantin completely and has not had to go on another medication. The RA is resolving, it has been 4 mos. since he has been off, it started improving almost immediately. Unfortunately, just after starting weaning off the Dilantin other health problems hit, a long story. The part I am wondering about is his current problem of shortness of breath due to inflammation of the lungs. Our family doctor now believes the anti-bodies from the Dilantin which had attacked the joints are now attacking the lining of the lungs. Has anyone else heard of or experienced this?
