Drug Interactions between silver sulfadiazine topical and Urobiotic-250
This report displays the potential drug interactions for the following 2 drugs:
- silver sulfadiazine topical
- Urobiotic-250 (oxytetracycline/phenazopyridine/sulfamethizole)
Interactions between your drugs
phenazopyridine silver sulfADIAZINE topical
Applies to: Urobiotic-250 (oxytetracycline / phenazopyridine / sulfamethizole) and silver sulfadiazine topical
Some of the medication in silver sulfADIAZINE topical may be absorbed into the bloodstream following local application. When present in sufficient concentrations in the blood, silver sulfADIAZINE topical may cause methemoglobinemia, a rare condition that can lead to oxygen deprivation in tissues and vital organs due to reduced oxygen-carrying capacity of the blood. Methemoglobinemia is most likely to occur when silver sulfADIAZINE topical is used in burn patients to prevent infection. The risk is increased when combined with other medications that can also induce methemoglobinemia such as phenazopyridine. Individuals may be more susceptible to developing methemoglobinemia during treatment with these medications if they are very young (especially neonates and infants) or have anemia, diseases of the heart or lungs, blood circulation disorders, liver cirrhosis, shock, sepsis, and certain genetic predispositions such as NADH cytochrome-b5 reductase deficiency, glucose-6-phosphate dehydrogenase deficiency, and hemoglobin M. In addition, use of silver sulfADIAZINE topical on inflamed or abraded areas or broken skin, as well as excessive use such as application of large doses or on larger than recommended areas, can increase absorption and result in high blood levels of the medication. Close medical supervision may be necessary when medications that can cause methemoglobinemia are used together. Signs and symptoms of methemoglobinemia may be delayed by several hours after treatment. Patients (or their caregivers) should seek immediate medical attention if they develop a gray discoloration of the skin, mouth, or nail bed; nausea; headache; dizziness; lightheadedness; fatigue; shortness of breath; rapid or shallow breathing; a rapid heartbeat; palpitation; anxiety; or confusion. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food/lifestyle interactions
oxytetracycline food/lifestyle
Applies to: Urobiotic-250 (oxytetracycline / phenazopyridine / sulfamethizole)
Do not take iron supplements, multivitamins, calcium supplements, antacids, or laxatives within 2 hours before or after taking oxytetracycline. These products can make oxytetracycline less effective in treating your infection. Do not take oxytetracycline with milk or other dairy products, unless your doctor has told you to. Dairy products can make it harder for your body to absorb the medication.
oxytetracycline food/lifestyle
Applies to: Urobiotic-250 (oxytetracycline / phenazopyridine / sulfamethizole)
Consumer information for this interaction is not currently available.
GENERALLY AVOID: The oral bioavailability of quinolone and tetracycline antibiotics may be reduced by concurrent administration of preparations containing polyvalent cations such as aluminum, calcium, iron, magnesium, and zinc. Therapeutic failure may result. The proposed mechanism is chelation of quinolone and tetracycline antibiotics by di- and trivalent cations, forming an insoluble complex that is poorly absorbed from the gastrointestinal tract. Reduced gastrointestinal absorption of the cations should also be considered.
MANAGEMENT: Concomitant administration of oral quinolone and tetracycline antibiotics with preparations containing aluminum, calcium, iron, magnesium, and/or zinc salts should generally be avoided. Otherwise, the times of administration should be staggered by as much as possible to minimize the potential for interaction. Quinolones should typically be dosed either 2 to 4 hours before or 4 to 6 hours after polyvalent cation preparations, depending on the quinolone and formulation. Likewise, tetracyclines and polyvalent cation preparations should typically be administered 2 to 4 hours apart. The prescribing information for the antibiotic should be consulted for more specific dosing recommendations.
