What is bismuth subcitrate potassium, metronidazole, and tetracycline (Pylera)?

Bismuth subcitrate potassium, metronidazole, and tetracycline (Pylera) is a combination medicine used to treat peptic ulcer (duodenal ulcer) with Helicobacter pylori infection. Pylera is usually given together with omeprazole (Prilosec).

Pylera may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking Pylera?

You should not use Pylera if you are allergic to bismuth subcitrate potassium, metronidazole, or tetracycline, or if:

  • you have severe kidney disease;
  • you drink alcohol daily;
  • you regularly consume foods or medicines that contain propylene glycol;
  • you took disulfiram (Antabuse) within the past 14 days; or
  • you also use methoxyflurane.

Tell your doctor if you have ever had:

  • kidney disease;
  • liver disease;
  • Cockayne syndrome (a rare genetic disorder);
  • a blood cell disorder; or
  • any type of infection.

Metronidazole has caused cancer in animal studies. It is not known whether this would occur in humans taking Pylera. Ask your doctor about your risk.

Do not use Pylera if you are pregnant. Tetracycline can cause permanent tooth discoloration and affect growth in the baby.

Pylera can make birth control pills less effective. Ask your doctor about other birth control options such as an injection, implant, skin patch, vaginal ring, condom, diaphragm, cervical cap, or contraceptive sponge.

You should not breastfeed within 2 days after using Pylera. If you use a breast pump during this time, throw out any milk you collect. Do not feed it to your baby.

Not approved for use by anyone younger than 18 years old.

How should I take Pylera?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Take your medicine with a full glass (8 ounces) of water. Swallow the capsule whole. Do not take with milk.

Pylera is usually taken after meals and at bedtime. If you also take omeprazole (Prilosec), take it after your morning and evening meals.

Keep using this medicine even if your symptoms quickly improve. Skipping doses could make your infection resistant to medication. Pylera will not treat a viral infection (flu or a common cold).

Bismuth can affect the results of certain x-rays or medical tests. Tell any doctor who treats you that you are using Pylera.

Store at room temperature away from moisture and heat. If you use the 10-day Pylera package, keep each capsule in the blister pack until you are ready to take a dose.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

If you miss more than 4 doses, call your doctor for instructions.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking Pylera?

While taking Pylera and for 3 days after your last dose: Do not drink alcohol or consume foods, medicines, or other products that contain alcohol or propylene glycol. You may have unpleasant effects such as headaches, nausea, vomiting, stomach cramps, and warmth or tingling under your skin.

Avoid taking Pylera at the same time you consume milk or other dairy products, or take multivitamins, mineral supplements, or antacids. These products can make it harder for your body to absorb the medicine.
