ADVERSE REACTIONS ELMIRON ® was evaluated in clinical trials in a total of 2627 patients (2343 women, 262 men, 22 unknown) with a mean age of 47 [range 18 to 88 with 581 (22%) over 60 years of age].
Of the 2627 patients, 128 patients were in a 3-month trial and the remaining 2499 patients were in a long-term, unblinded trial.
Deaths occurred in 6/2627 (0.2%) patients who received the drug over a period of 3 to 75 months.
The deaths appear to be related to other concurrent illnesses or procedures, except in one patient for whom the cause was not known.
Serious adverse events occurred in 33/2627 (1.3%) patients.
Two patients had severe abdominal pain or diarrhea and dehydration that required hospitalization.
Because there was not a control group of patients with interstitial cystitis who were concurrently evaluated, it is difficult to determine which events are associated with ELMIRON ® and which events are associated with concurrent illness, medicine, or other factors.

WARNINGS Retinal Pigmentary Changes Pigmentary changes in the retina, reported in the literature as pigmentary maculopathy, have been identified with long-term use of ELMIRON ® (see ADVERSE REACTIONS ).
Although most of these cases occurred after 3 years of use or longer, cases have been seen with a shorter duration of use.
While the etiology is unclear, cumulative dose appears to be a risk factor.
Visual symptoms in the reported cases included difficulty reading, slow adjustment to low or reduced light environments, and blurred vision.
The visual consequences of these pigmentary changes are not fully characterized.
Like all medications, Elmiron can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
