Warnings and Precautions
PRAZOLOC OTC should not be used for the treatment of mild gastro-intestinal complaints, such as nervous dyspepsia (indigestion due to stress or anxiety). Before you start treatment with PRAZOLOC OTC, you may have to go for an endoscopic examination (swallow the scope). During this procedure a small piece of tissue may be taken from the stomach, oesophagus, or duodenum for examination under a microscope. This is called a biopsy and biopsies are necessary to rule out the possibility of cancer of the stomach or oesophagus. It is important that you inform your doctor if you recently experienced significant unintentional weight loss, recurrent vomiting, pain with swallowing, vomiting of blood or a substance resembling coffee grounds, or passed dark, foul-smelling, tarry stools. Responding to treatment with PRAZOLOC OTC does not rule out the presence of stomach or oesophageal cancer. Performing an endoscopic examination with biopsy prior to treatment will enable your doctor to make a timely diagnosis of cancer and to institute appropriate treatment.
Daily treatment with any acid-blocking medicine, such as PRAZOLOC OTC, over a long period of time (e.g. longer than 3 years) may lead to malabsorption of vitamin B12. Inadequate absorption of vitamin B12 may lead to anaemia (shortage of red blood cells). Please inform your doctor as soon as possible if you experience weakness, tiredness or light-headedness, rapid heartbeat and breathing, pale skin, sore tongue, easy bruising or bleeding, bleeding gums, or stomach upset.
You may have to go for blood tests to monitor your liver enzyme levels while you are taking PRAZOLOC OTC. While on treatment of PRAZOLOC OTC you may be at risk of developing a kidney disorder called interstitial nephritis, causing the inside of your kidneys to become inflamed. This condition may progress to renal failure as it is not necessarily reversed when treatment with PRAZOLOC OTC is stopped (see "Possible side-effects")
Use of PRAZOLOC OTC as preventative of gastroduodenal ulcers, induced by non-selective non-steroidal anti-inflammatory drugs (NSAIDs) should be restricted to patients who require continued NSAID treatment and have an increased risk to develop gastro-intestinal complications.
