I got the dark orange urine. It breaks down into 5ASA and sulfapiridine(sp) which might smell.
There are rare problems with the liver and kidneys just like the other 5ASAs. There are rare white and red blood cell problems which I don't think happen with the other 5asas. regular blood testing is supposed to be done but haven't heard of doctors doing them as much as the drug maker warns;.
Complete blood counts, including differential white cell count and liver function tests, should be performed before starting AZULFIDINE EN-tabs and every second week during the first three months of therapy. During the second three months, the same tests should be done once monthly and thereafter once every three months, and as clinically indicated. Urinalysis and an assessment of renal function should also be done periodically during treatment with AZULFIDINE EN-tabs.
The determination of serum sulfapyridine levels may be useful since concentrations greater than 50 μg/mL appear to be associated with an increased incidence of adverse reactions.
The most likely thing to happen is what happened to me. Reaction to sulfapyridine. I had this happen a month into taking the drug. Basically flu symptoms +bad headaches without anything respiratory. So if you think you have the flu make sure it isn't the drug.
