Interactions between your drugs

Major

bismuth subsalicylate influenza virus vaccine, live

Applies to: bismuth subsalicylate / metronidazole / tetracycline and FluMist (influenza virus vaccine, live)

Vaccination with influenza virus vaccine, live is not recommended in children less than 18 years of age who are receiving bismuth subsalicylate therapy. The use of bismuth subsalicylate or related medications has been linked to a serious and potentially fatal condition called Reye's syndrome in children with certain viral infections such as influenza or chicken pox. Because influenza virus vaccine, live contains live (but weakened) virus, there is some concern that it can cause Reye's syndrome when used with bismuth subsalicylate. The immunizing doctor should be informed of current or recent therapy with bismuth subsalicylate so that appropriate measures and/or precautions can be taken, such as substituting influenza virus vaccine, live with a vaccine that contains inactivated virus. Never give bismuth subsalicylate to children or adolescents who have a fever without talking to a doctor, especially if they also have flu symptoms or chicken pox. It is important to tell the doctor about all other medications being used, including vitamins and herbs. Do not stop using any medications without first talking to the doctor.

Drug and food interactions

Major

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.

Moderate

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.

Moderate

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.
