Patient leaflet - Zoton Fastab 30 mg
1. What Zoton is and what it is used for
The active ingredient in Zoton is lansoprazole, which is a proton pump inhibitor. Proton pump inhibitors reduce the amount of acid that your stomach makes.
Your doctor may prescribe Zoton for the following indications:
- Treatment of duodenal and stomach ulcer
Treatment of inflammation in your
oesophagus (reflux oesophagitis)
- Prevention of reflux oesophagitis
- Treatment of heartburn and acid regurgitation
Treatment of infections caused by the
bacteria Helicobacter pylori when given in combination with antibiotic therapy
Treatment or prevention of duodenal or
stomach ulcer in patients requiring continued non-steroidal anti-inflammatory drugs (NSAID) treatment (NSAID treatment is used against pain or inflammation)
- Treatment of Zollinger-Ellison syndrome. Your doctor may have prescribed Zoton for another indication or with a dose different from that which is written in this information leaflet. Please take your medicine in consultation with your doctor. You must talk to a doctor if you do not feel better or if you feel worse after 14 days.
2. What you need to know before you take Zoton
Do not take Zoton:
if you are allergic to lansoprazole or any of
the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Please tell your doctor if you have serious liver disease. The doctor may have to adjust your dosage.
Your doctor may perform or have performed an additional investigation called an endoscopy in order to diagnose your condition and/or exclude malignant disease.
If severe or persistent diarrhoea occurs during the treatment with Zoton contact your doctor immediately, as Zoton has been associated with a small increase in infectious diarrhoea. If your doctor has given you Zoton in addition to other medicines intended for the treatment of Helicobacter pylori infection (antibiotics) or together with anti-inflammatory medicines to treat your pain or rheumatic disease: please also read the package leaflets of these medicines carefully. If you take Zoton for more than three months it is possible that the levels of magnesium in your blood may fall. Low levels of magnesium can be seen as fatigue, involuntary muscle contractions, disorientation, convulsions, dizziness, increased heart rate. If you get any of these symptoms, please tell your doctor promptly. Low levels of magnesium can also lead to a reduction in potassium or calcium levels in the blood. Your doctor may decide to perform regular blood tests to monitor your levels of magnesium.
Taking a proton pump inhibitor like Zoton, especially over a period of more than one year, may slightly increase your risk of fracture in the hip, wrist or spine. Tell your doctor if you have osteoporosis (reduced bone density) or if your doctor has told you that you are at risk of getting osteoporosis (for example, if you are taking steroids).
This medicine may affect the way that your body absorbs vitamin B12, particularly if you need to take it for a long time. Please 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
- Pins and needles
- Sore or red tongue, mouth ulcers
- Muscle weakness
- Disturbed vision
- Problems with memory, confusion, depression If you take Zoton on a long-term basis (longer than 1 year) your doctor will probably keep you under regular surveillance. You should report any new and exceptional symptoms and
circumstances whenever you see your doctor. Talk to your doctor before taking Zoton:
if you are due to have a specific blood test
(Chromogranin A).
if you have ever had a skin reaction after
treatment with a medicine similar to Zoton that reduces stomach acid.
Serious skin reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in association with lansoprazole treatment. Stop using Zoton and seek medical attention immediately if you notice any of the symptoms described in section 4. If you get a rash on your skin, especially in areas exposed to the sun tell your doctor as soon as you can, as you may need to stop your treatment with Zoton. Remember to also mention any other ill-effects like pain in your joints. When taking lansoprazole, inflammation in your kidney may occur. Signs and symptoms may include decreased volume of urine or blood in your urine and/or hypersensitivity reactions such as fever, rash, and joint stiffness. You should report such signs to the treating physician. Other medicines and Zoton
