  • Phenazopyridine

    Hi, I am new to the forum and I have a question about a drug. I have burning during urination and my Urologist prescribed Phenazopyridine for the burning.I know it turns the color of your urine orange. I was doing a search on the net about the side effects and warnings.According to the information I read on the website,Phenazopyridine caused cancer in lab rats and mice.I was floored when I read this. I thought, why is this drug still being prescribed to patients if its a known carcinogen.? I know some doctors don't know the side effects and warnings of the drug the are prescribing to their patients.Any help will be appreciated.

    Phenazopyridine is commonly called pyridium --- and the over the counter variety is AZO. If you do a search on the forums for either term, you'll find lots of posts about it.

        pyridium caution

        You really need the read the info. that the pharmacist gives you. You can only take this two days in a row. then I don't know how long it's safe to wait and then try again. Need to ask the pharmacist. I know It can cause an anemia & that is not good news.

          Thanks Lizzie. My Urologist said I could use it longer tan two days.I have heard of people using it for two months. I thought about taking uribel or urelle,but both of these drugs can cause acute urinary retention&I have urinary retention.

            When my urologist prescribed this med - he told me to take it five days in a row and then wait one week or two, and do it again. He also said I could take it as needed for burning. I tend to use it for a couple of days, and then stop for a couple, then start up again. But now I'm interested in doing more research about it. Thanks!

            Current Meds:
            1 Elmiron 100mg 3x a day
            1 Cimetidine 300mg 2x a day
            4 Gabapentin 300mg 3x a day (3600mg)
            1 - 2 Atarax 25mg at bedtime
            1 baclofen 10mg 3x a day as needed
            200mg of Pyridium 3x a day (usually do in cycles - on for a week or two as needed) - I am very careful about this.
            2 belladonna and opium suppositories as needed for pain daily.
            Bladder instillations (Lidocaine, Heparin, & Sodium Bicarbonate)

            I have tried but failed -
            lidocaine instillations, heparin instillations, oxybutynin by mouth also called ditropan, tylenol 3s with coedine, cyclobenzaphrine, Ativan, vesicare, Oxytrol patches worked for 3 to 4 years and then failed, I tried Uracyst and had some success but my urologist felt that it was not successful so we moved on to trying something else. .
