What is TEVA-OMEPRAZOLE used for?

TEVA-OMEPRAZOLE is used to treat problems caused by too much acid in the stomach such as:

  • stomach ulcers (sores).
  • duodenal ulcers (sores on the first part of the intestine).
  • stomach and duodenal ulcers caused by a bacterium, Helicobacter pylori.
  • reflux esophagitis (tissue damage caused by stomach acid and juices moving up the food tube).
  • symptoms of reflux disease (e.g. heartburn, backup of stomach contents to the throat).
  • ulcers caused by nonsteroidal anti-inflammatory drugs (drugs for pain and sore joints).
  • dyspepsia, a group of symptoms which may include stomach pain/discomfort, heartburn and backup of stomach contents to the throat. Dyspepsia can be caused by the other conditions in this list.
  • a rare condition where the stomach produces too much acid (Zollinger-Ellison syndrome).

How does TEVA-OMEPRAZOLE work?

TEVA-OMEPRAZOLE is a medicine called a proton pump inhibitor (PPI). TEVA-OMEPRAZOLE works by reducing the amount of acid made in your stomach.

What are the ingredients in TEVA-OMEPRAZOLE?

Medicinal ingredients: omeprazole magnesium

Non-medicinal ingredients: TEVA-OMEPRAZOLE 10 mg and 20 mg tablets contain the following non-medicinal ingredients black iron oxide, collodial silicon dioxide, crospovidone, hydroxypropyl methylcellulose, lecithin, mannitol, methacrylic acid copolymer, microcrystalline cellulose, polyethylene glycol, red iron oxide, shellac, simethicone, sodium stearyl fumarate, talc, titanium dioxide and tributyl citrate. TEVA-OMEPRAZOLE 10 mg tablets also contain yellow iron oxide.

TEVA-OMEPRAZOLE comes in the following dosage forms:

Tablets of omeprazole 10 mg or 20 mg.

Do not use TEVA-OMEPRAZOLE if:

  • you are allergic to omeprazole, substituted benzimidazoles or any of the other ingredients in TEVA-OMEPRAZOLE (see “What are the ingredients in TEVA-OMEPRAZOLE?”).
  • you are taking rilpivirine.

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take TEVA-OMEPRAZOLE. Talk about any health conditions or problems you may have, including if you:

  • have had any health problems in the past.
  • have severe liver problems now or have had in the past.
  • are pregnant or plan to become pregnant.

  • are breastfeeding or planning to breastfeed, as omeprazole is excreted in breast milk.
  • take any other medications, including ones you can buy without a prescription.
  • are due to have a specific blood test (Chromogranin A).

Other warnings you should know about:

TEVA-OMEPRAZOLE is not recommended for use in patients under 18 years of age.

This medicine should be used at the lowest dose and for the shortest time suitable for your condition. Talk to your doctor if you have any concerns about your treatment.

Treatment in combination with antibiotics: if you experience symptoms such as severe (bloody or repeated watery) diarrhea, with or without fever, abdominal pain or tenderness, you may have bowel inflammation caused by a bacterial infection (Clostridium difficile). If this happens, stop taking the drug combination and call your healthcare professional immediately.

Tell your doctor or pharmacist about symptoms that may be a sign of a more serious problem in your stomach or intestine such as:

  • trouble swallowing.
  • unplanned weight loss.
  • vomiting blood or food.
  • black (blood-stained) stools.

Long-term use of PPIs may interfere with the absorption of Vitamin B12 from the diet. This may cause a shortage of Vitamin B12 in your body. Talk to your doctor about this risk.

Long-term use of PPIs may lead to low blood magnesium in some people. When blood magnesium is lower than normal, it may also lead to low blood calcium and low blood potassium.

Using PPIs for a long time (every day for a year or longer) may increase risks of broken bones of the hip, wrist or spine. Talk to your doctor about this risk.

Using TEVA-OMEPRAZOLE for a long period of time may cause a growth in your stomach (polyp), especially after one year.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.

The following may interact with TEVA-OMEPRAZOLE:

  • medication for HIV: TEVA-OMEPRAZOLE may decrease the effectiveness of some drugs used for HIV treatment; atazanavir, nelfinavir and saquinavir should not be used with TEVA-OMEPRAZOLE.
  • a high-dose of methotrexate (a drug used in high doses to treat cancer). TEVA-OMEPRAZOLE may need to be temporarily withdrawn.
  • clopidogrel, which is used for the prevention of blood clots: TEVA-OMEPRAZOLE may interact with this drug, therefore, use with clopidogrel should be avoided.
  • drug effects may be influenced if TEVA-OMEPRAZOLE is taken at the same time as some drugs used to prevent fungal infections (itraconazole, ketoconazole, voriconazole), anxiety (diazepam), epilepsy (phenytoin), blood clotting (warfarin or other vitamin K blockers), transplant rejection (tacrolimus), poor circulation in the legs (cilostazol)*, heart problems (digoxin), treatment for tuberculosis (rifampin), St John’s Wort (Hypericum perforatum) or a certain type of anticancer drug (erlotinib or any other anticancer drug from the same class).

How to take TEVA-OMEPRAZOLE:

Follow your doctor’s directions carefully. They may be different from the information contained in this leaflet.

  • Take all doses of TEVA-OMEPRAZOLE that your doctor prescribes, even when you feel well. Doses every day are needed to help damaged areas heal.
  • If you take TEVA-OMEPRAZOLE with antibiotic drugs, it is important that you take all medications at the right time of day for the whole treatment period. Studies have shown that patients who take their medications as prescribed have better ulcer healing rates and greater success getting rid of their H. pylori infection.
  • Take TEVA-OMEPRAZOLE until your doctor tells you to stop. Even if you start to feel better in a few days, your symptoms may return if TEVA-OMEPRAZOLE is stopped too soon. TEVA-OMEPRAZOLE needs to be taken for the full treatment to help correct acid problems.
  • TEVA-OMEPRAZOLE may be taken with food or on an empty stomach.

    Serious Drug Interactions

    • Do not take TEVA-OMPEPRAZOLE if you are taking rilpivirine (a drug used for HIV).
  • Do not chew or crush your TEVA-OMEPRAZOLE tablets. Swallow the tablet whole with half a glass of water.

Usual dose:

Your doctor may tell you to take TEVA-OMEPRAZOLE:

  • 10-40 mg once a day for 2-8 weeks to heal damaged areas.
  • 10-40 mg to control symptoms of reflux disease or to stop reflux esophagitis from coming back.
  • 20 mg to stop ulcers from returning while you take your medicine for pain and joint problems.
  • 60 mg once a day to treat Zollinger-Ellison syndrome
  • In combination with antibiotic drugs for one week to treat ulcers caused by Helicobacter pylori.

    • as Omeprazole, Amoxicillin and Clarithromycin Triple Therapy: The recommended dose for eradication of H. pylori is TEVA-OMEPRAZOLE 20 mg, amoxicillin 1000 mg and clarithromycin 500 mg, all twice daily for seven days.
    • or as Omeprazole, Metronidazole and Clarithromycin Triple Therapy: The recommended dose for eradication of H. pylori is TEVA-OMEPRAZOLE 20 mg, metronidazole 500 mg and clarithromycin 250 mg, all twice daily for seven days.
    • If your ulcer is bothering you, your doctor may recommend further treatment with TEVA-OMEPRAZOLE to make sure that your ulcer is healed.

Overdose:

If you think you, or a person you are caring for, have taken too much TEVA-OMEPRAZOLE, contact a healthcare professional, hospital emergency department, or regional Poison Control Centre immediately, even if there are no symptoms.

Missed Dose:

If you miss a dose of TEVA-OMEPRAZOLE and remember within 12 hours, take it as soon as possible. Then go back to your regular schedule. However, if more than 12 hours have passed when you remember, do not take the missed tablet. Do not double the dose. Just take your next dose on time.
