1. What Contix is and what it is used for
Contix contains the active substance pantoprazole, a selective “proton pump inhibitor”, a medicine that reduces the amount of acid produced in the stomach. It is used to treat conditions where the stomach produces too much acid, such as reflux oesophagitis, and peptic ulcers.
Contix is used in adults and adolescents aged 12 years and above for:
- Treatment of reflux oesophagitis, a condition in which the stomach acid flows back into the oesophagus (the tube that carries food from the mouth to the stomach), causing pain and discomfort.
Contix is used in adults for:
- Treatment of Helicobacter pylori (a type of bacteria) infections in combination with two antibiotics (eradication therapy) to eliminate the bacteria and prevent recurrence of ulcers.
- Treatment of peptic ulcers, including stomach and duodenal ulcers.
- Treatment of Zollinger-Ellison syndrome and other conditions where the stomach produces too much acid.
2. Important information before taking Contix
When not to take Contix:
- If you are allergic to pantoprazole or any of the other ingredients of this medicine.
- If you have previously experienced an allergic reaction to other proton pump inhibitors.
Warnings and precautions
Before taking Contix, tell your doctor or pharmacist or nurse if:
- You have severe liver problems. Your doctor may need to monitor your liver function more closely during treatment with Contix.
- You have a deficiency of vitamin B12 or have risk factors for a deficiency, as pantoprazole may reduce the absorption of vitamin B12.
- You are taking HIV protease inhibitors, such as atazanavir, as Contix may reduce their effectiveness.
- You have osteoporosis or are at risk of osteoporosis, as long-term use of proton pump inhibitors may increase the risk of fractures of the hip, wrist, or spine.
- You have ever had a skin reaction after treatment with a medicine that reduces stomach acid, as you may be at a higher risk of developing a skin reaction with Contix.
- You have ever had a skin rash or other allergic reactions, especially after taking medicines, as you may be at a higher risk of developing a skin reaction with Contix.
- A specific blood test (chromogranin A) is planned.
Tell your doctor or pharmacist or nurse immediately if you notice any of the following symptoms, which could be a sign of a more serious condition:
- Unintentional weight loss (not due to diet or exercise).
- Vomiting, especially if it is repeated.
- Blood in your vomit or black, tarry stools.
- Difficulty swallowing or pain when swallowing.
- Pale or tired skin (anaemia).
- Chest pain.
- Abdominal pain.
- Severe and/or persistent diarrhoea, as Contix may increase the risk of infectious diarrhoea.
Your doctor may decide to perform tests to rule out a malignant condition, as treatment with pantoprazole may alleviate symptoms of a malignant condition and delay diagnosis. If symptoms persist despite treatment, further tests should be considered.
Children and adolescents
Contix is not recommended for children under 12 years of age, as the safety and efficacy have not been established.
Contix with other medicines
Tell your doctor or pharmacist about all the medicines you are taking, have recently taken, or might take, including those obtained without a prescription.
- Medicines such as ketoconazole, itraconazole, and posaconazole (used to treat fungal infections) or erlotinib (used to treat certain types of cancer), as Contix may reduce their effectiveness.
- Warfarin and phenprocoumon, which affect blood clotting, may require additional monitoring.
- Medicines used to treat HIV, such as atazanavir.
- Methotrexate (used to treat rheumatoid arthritis, psoriasis, and cancer), as pantoprazole may increase the levels of methotrexate in the blood.
- Fluvoxamine (used to treat depression and other mental health conditions), as the dose may need to be reduced.
- Rifampicin (used to treat infections).
- St John's Wort (Hypericum perforatum) (used to treat mild depression).
