Other warnings you should know about:
JAMP-Omeprazole DR 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 JAMP-Omeprazole DR 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.
