I am taking the generic for Elmiron ( Pentosan Polysulfate 100mg Cap ). Since I started taking it I have gained 10lbs in one month. I am trying to find out if it is because of this drug. I have Interstitial Cystitis. Along with this medication I take Utira-C, also for the Interstitial Cystitis. I take thyroid meds my tests have come out fine on the level. Can anyone help me with this please. Thank you
