Can I take phenazopyrid with septra (sulfamethoxazole and trimethoprim)?

DrugDrug interaction. Always tell your prescribing physician & dispensing pharmacist everything you take, whether prescription or otc. Include herbs & dietary supplements, too. Several drug-drug interaction checkers are available online. I like www.Epocrates.Com & www.Drugs.Com. Latter says safe to take together: http://www.Drugs.Com/interactions-check.Php?Drug_list=1835-0, 2128-1385. In fact, such a combo pill exists!
