Bismuth subcitrate/metronidazole/tetracycline - oral
Bismuth subcitrate/metronidazole/tetracycline - oral
This combination medication is used with an acid blocker (for example, a proton pump inhibitor such as omeprazole). It is used to treat stomach/intestinal ulcers caused by the bacteria H. pylori and to prevent the ulcers from returning.
Each capsule contains 3 medications: bismuth subcitrate, metronidazole, and tetracycline. Bismuth subcitrate is often used to treat upset stomach, but it is used in this combination to help stop the growth of bacteria. Metronidazole and tetracycline are antibiotics used to treat a wide variety of bacterial infections. They work by stopping the growth of bacteria.
This product treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.
This product is not recommended for use in children.
Take this medication by mouth 4 times daily (after meals and at bedtime) for 10 days. Take each dose (3 capsules) with a full glass of water (8 ounces or 240 milliliters) unless your doctor directs you otherwise. Swallow the capsules whole. Do not crush or chew the capsules. Do not lie down for at least 10 minutes after taking this medication.
Follow your doctor's instructions on how to correctly take an acid blocker with this medication.
Take this medication 2 to 3 hours before or after taking any products containing magnesium, aluminum, or calcium. These products bind with tetracycline, preventing its full absorption. Some examples include quinapril, certain forms of didanosine (e.g., chewable/dispersible buffered tablets or pediatric oral solution), vitamins/minerals, and antacids. Dairy products (e.g., milk, yogurt), calcium-enriched juice, sucralfate, iron, and zinc are also included.
Take this medication regularly in order to get the most benefit from it. Continue to take this medication and the acid blocker until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection/ulcer.
Tell your doctor if your condition persists or worsens.
Nausea, diarrhea, upset stomach, abdominal pain, changes in taste, headache, or dizziness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
