This report displays the potential drug interactions for the following 2 drugs:
- bismuth subsalicylate/metronidazole/tetracycline
- Levaquin (levofloxacin)
Interactions between your drugs
tetracycline bismuth subsalicylate
Applies to: bismuth subsalicylate / metronidazole / tetracycline and bismuth subsalicylate / metronidazole / tetracycline
Using bismuth subsalicylate together with tetracycline may decrease the effects of tetracycline. Administration of tetracycline and bismuth subsalicylate should be separated by two to three hours. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. 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.
metroNIDAZOLE levoFLOXacin
Applies to: bismuth subsalicylate / metronidazole / tetracycline and Levaquin (levofloxacin)
Using metroNIDAZOLE together with levoFLOXacin can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications, whether together or alone. 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 interactions
metroNIDAZOLE food
Applies to: bismuth subsalicylate / metronidazole / tetracycline
Consumption of alcoholic beverages or products containing alcohol or propylene glycol during treatment with metroNIDAZOLE is not recommended. Doing so may occasionally trigger a reaction in some patients similar to the disulfiram reaction, which includes unpleasant effects such as flushing, throbbing in head and neck, throbbing headache, difficulty breathing, nausea, vomiting, sweating, thirst, chest pain, rapid heartbeat, palpitation, low blood pressure, dizziness, lightheadedness, blurred vision, and confusion. Rarely, more severe reactions may include abnormal heart rhythm, heart attack, heart failure, unconsciousness, convulsions, and even death. Patients treated with metroNIDAZOLE should continue to avoid using any products containing alcohol or propylene glycol for at least 3 days until after completion of therapy. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. 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.
tetracycline food
Applies to: bismuth subsalicylate / metronidazole / tetracycline
Do not take iron supplements, multivitamins, calcium supplements, antacids, or laxatives within 2 hours before or after taking tetracycline. These products can make tetracycline less effective in treating your infection. Do not take tetracycline 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.
levoFLOXacin food
Applies to: Levaquin (levofloxacin)
When levoFLOXacin as the oral solution is given with enteral (tube) feedings, levoFLOXacin may not work as well. You could interrupt the feeding for 1 hour before and 2 hours after the levoFLOXacin dose. However, this still may not entirely avoid the interaction and may not always be feasible. LevoFLOXacin oral tablets may be taken without regard to food. 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.
tetracycline food
Applies to: bismuth subsalicylate / metronidazole / tetracycline
Iron can bind to tetracycline 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 tetracycline 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.
