There are 2 alcohol/food/lifestyle interactions with oxytetracycline / phenazopyridine / sulfamethizole which include:
oxytetracycline ↔ multivitamins with minerals
Moderate Drug Interaction
Iron can bind to oxytetracycline in the gastrointestinal tract, which may prevent their absorption into the bloodstream and possibly reduce their effectiveness. To avoid or minimize the interaction, iron-containing medications and oxytetracycline should preferably be taken at least three to four hours apart in most cases. Talk to your doctor if you have any questions or concerns, or if you have trouble separating the dosing times. Your doctor may be able to prescribe alternatives that do not interact. 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.
