Can I take phenazopridine 100 mg PRN instead of 3 times a day? This is a four day dose with no refills. Is it unwise to ask for a refill?

Brief Answer:
Can Akme Phenazopyridine Twice daily

Detailed Answer:
Thanks for query
You hadbeencatheterized while getting operated for spine surgery and since thathaveproblemin passing urine

This is mostly due to either inflammation of urethra caused by catheter or due to Enlarged Prostate.

You need to consult qualified Urologist for clinical and digital Rectal Examination and get following basic tests done to establish diagnosis
1) Urine routine and urine culture
2) Ultrasound Scanning of abdomen and pelvis

Further treatment will depend upon the results of these tests and final diagnosis

Till then continue taking Phenazopyridine twice daily

Thanks and Regards Do write if you need any help.
