From facing a bill of $390 for some medication, just one medication, my husband was able to get it for $18.95. We couldn't believe it, we thought it was a joke! I thought it was a scam! ... We're currently saving about $600 a month just on 4 different medications. That makes a huge difference. — Rebecca
Blink has changed my life because after I lost my job... I was unable to afford prescriptions because I had no health insurance, like many of us Americans. With Blink, I was able to get all my prescriptions. — Farrian
This combination medication is used with an acid blocker (e.g., 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 (e.g., common cold, flu). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.
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 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.
Your tongue may turn dark in color while you are taking this medication. This is harmless, and the effect will disappear when you stop the medication.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if any of these unlikely but serious side effects occur: numbness/tingling of arms/legs, discolored teeth, mental/mood changes (such as confusion, anxiety, irritability, depression), difficult/painful swallowing, heartburn, fast/pounding heartbeat, ringing in the ears, frequent/painful urination.
Tell your doctor right away if any of these rare but very serious side effects occur: severe headache, stiff/painful neck, signs of kidney problems (such as change in the amount of urine), signs of infection (e.g., fever, persistent sore throat), easy bruising/bleeding, unusual weakness/tiredness, seizures, chest pain, symptoms of liver disease (such as nausea/vomiting that doesn't stop, loss of appetite, severe stomach/abdominal pain, yellowing eyes/skin, dark urine).
This product commonly causes dark stools that are usually not serious. However, you may not be able to tell this effect apart from blood in the stool, which could be a sign of a serious condition. Therefore, tell your doctor right away if you have dark stools.
Tetracycline may rarely cause a serious increase in pressure inside the skull (intracranial hypertension-IH). The risk of this side effect is greater for women of childbearing age who are overweight or who have had IH in the past. If IH develops, it usually goes away after tetracycline is stopped; however, there is a chance of permanent vision loss or blindness. Get medical help right away if you have: persistent/severe headache, vision changes (such as blurred/double vision, decreased vision, sudden blindness), persistent nausea/vomiting.
This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of the following symptoms because these products may make them worse. Tell your doctor right away if you develop: persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool.
Use of this medication for prolonged or repeated periods may result in oral thrush or a new yeast infection. Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: fever, swollen lymph nodes, rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
