1. What is Omeprazole Teva-ratio and what is it used for

Omeprazole Teva-ratio contains the active substance omeprazole. It belongs to a group of medicines called “proton pump inhibitors”. These medicines work by reducing the amount of acid produced by the stomach.

Omeprazole Teva-ratio is used to treat the following conditions:

In adults:

  • “Gastro-oesophageal reflux disease” (GORD). In this condition, acid from the stomach passes into the gullet (the tube that connects the throat to the stomach), causing pain, inflammation and heartburn.
  • Ulcers in the upper part of the intestine (duodenal ulcer) or in the stomach (gastric ulcer)
    • Ulcers caused by a bacteria called “Helicobacter pylori”. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
    • Ulcers caused by medicines called non-steroidal anti-inflammatory drugs (NSAIDs). Omeprazole may be used to prevent ulcers if you are taking NSAIDs.
  • Excess acid in the stomach caused by a tumour in the pancreas (Zollinger-Ellison syndrome).

In children:

Children over 1 year of age and ≥ 10 kg

  • “Gastro-oesophageal reflux disease” (GORD). In this condition, acid from the stomach passes into the gullet (the tube that connects the throat to the stomach), causing pain, inflammation and heartburn.

In children, the symptoms of the disease can include return of stomach contents to the mouth (regurgitation), vomiting and insufficient weight gain.

Children over 4 years of age and adolescents

  • Ulcers caused by a bacteria called “Helicobacter pylori”. If your child has this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.

2. What you need to know before you take Omeprazole Teva-ratio

Do not take Omeprazole Teva-ratio:

  • If you are allergic to omeprazole or any of the other ingredients of this medicine (listed in section 6).
  • If you are allergic to medicines that contain proton pump inhibitors (e.g. pantoprazole, lansoprazole, rabeprazole, esomeprazole).
  • If you are taking a medicine that contains nelfinavir (used to treat HIV infection).

If you are not sure, talk to your doctor or pharmacist before taking omeprazole.

Warnings and precautions

Omeprazole Teva-ratio may hide the symptoms of other diseases. Therefore, if you experience any of the following before starting to take omeprazole or during treatment, consult your doctor immediately if:

  • You lose a lot of weight without reason and have trouble swallowing.
  • You have stomach pain or indigestion.
  • You start vomiting food or vomit blood.
  • Your stools are black (blood-stained faeces).
  • If you have severe or persistent diarrhoea, as omeprazole has been associated with a slight increase in infectious diarrhoea.
  • You have severe liver problems.
  • If you have ever had a skin reaction after treatment with a medicine similar to omeprazole to reduce stomach acid.
  • If you get a skin rash, especially in areas of the skin exposed to the sun, consult your doctor as soon as possible, as it may be necessary to interrupt treatment with omeprazole. Remember to mention any other symptoms you may notice, such as joint pain.
  • You are scheduled to have a specific blood test (Chromogranin A)

When taking omeprazole, kidney inflammation may occur. The signs and symptoms may include decreased urine output or blood in the urine and/or hypersensitivity reactions such as fever, rash and joint stiffness. You should inform your doctor of these signs.

If you take omeprazole for a long period (more than 1 year) your doctor will probably schedule regular check-ups. You should inform your doctor of any new or unusual symptoms or circumstances whenever you visit your doctor.

If you are taking proton pump inhibitors like omeprazole, especially for a period of more than one year, you may have a slightly increased risk of hip, wrist and spine fractures. Inform your doctor if you have osteoporosis or if you are taking corticosteroids (which can increase the risk of osteoporosis).

Omeprazole may interfere with some diagnostic tests (Chromogranin A). To avoid these interferences, treatment with omeprazole should be stopped at least five days before measurement.

This medicine may affect the way your body absorbs vitamin B12, especially if you need to take it for a long time. Contact your doctor if you notice any of the following symptoms, which could indicate low levels of vitamin B12:

  • Extreme tiredness or lack of energy
  • Numbness
  • Pain in the tongue or red tongue, mouth ulcers
  • Muscle weakness
  • Altered vision
  • Memory problems, confusion, depression

Taking Omeprazole Teva-ratio with other medicines

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines. Omeprazole may affect the way some medicines work and some medicines may affect omeprazole.

Do not take omeprazole if you are taking a medicine that contains nelfinavir (used to treat HIV infection).

Tell your doctor or pharmacist if you are taking any of the following medicines:

  • Ketoconazole, itraconazole, posaconazole or voriconazole (used to treat fungal infections)
  • Digoxin (used to treat heart problems)
  • Diazepam (used to treat anxiety, relax muscles or in epilepsy)
  • Phenytoin (used in epilepsy). If you are taking phenytoin, your doctor will need to monitor you when you start or stop treatment with omeprazole
  • Medicines used to prevent blood clots, such as warfarin or other vitamin K antagonists. Your doctor will need to monitor you when you start or stop treatment with omeprazole
  • Rifampicin (used to treat tuberculosis)
  • Atazanavir (used to treat HIV infection)
  • Tacrolimus (in cases of organ transplantation)
  • St. John's Wort (Hypericum perforatum) (used to treat mild depression)

  • Saquinavir (used to treat HIV infection)
  • Clopidogrel (used to prevent blood clots (thrombi)
  • Erlotinib (used to treat cancer)
  • Methotrexate (chemotherapy medicine used in high doses to treat cancer). If you are taking high-dose methotrexate, your doctor will need to temporarily stop treatment with omeprazole.

If your doctor has also prescribed the antibiotics amoxicillin and clarithromycin for you to treat ulcers caused by Helicobacter pyloriinfection, it is very important that you inform your doctor of any other medicines you are taking.

Other adverse effects are:

Frequent Adverse Effects (may affect up to 1 in 10 people)

  • Headache.
  • Effects on the stomach or intestine: diarrhea, stomach pain, constipation, and gas (flatulence).
  • Nausea or vomiting.
  • Benign polyps in the stomach.

  • Allergic reactions, sometimes very intense, including swelling of the lips, tongue, and throat, fever, and wheezing.
  • Low sodium levels in the blood. This can cause weakness, vomiting, and cramps.
  • Agitation, confusion, or depression.
  • Taste disorders.
  • Visual problems, such as blurred vision.
  • Sudden feeling of difficult breathing (bronchospasm).
  • Dry mouth.
  • Inflammation of the mouth.
  • An infection called "candidiasis" that can affect the intestine and is caused by a fungus.
  • Liver problems, such as jaundice, which can cause yellowing of the skin, dark urine, and fatigue.
  • Hair loss (alopecia).

Unknown Frequency (cannot be determined from available data)

  • Inflammation of the intestine (causing diarrhea).

Low magnesium levels can cause fatigue, involuntary muscle contractions, disorientation, convulsions, dizziness, and increased heart rate. If you experience any of these symptoms, go to the doctor immediately. Low magnesium levels can also cause a decrease in blood potassium and calcium levels. Your doctor may decide to perform periodic blood tests to monitor magnesium levels.
  • Skin rash, possibly with joint pain.

In very rare cases, omeprazole can affect the white blood cells and cause immunodeficiency. If you have an infection with symptoms such as fever with a severely deteriorated general condition or fever with symptoms of local infection, such as neck, throat, or mouth pain, or difficulty urinating, you should consult your doctor as soon as possible to perform a blood test and rule out a lack of white blood cells (agranulocytosis). It is essential that you provide information about the medication you are taking at that time.
