Medicine Overview of Opton 20mg Tablet

Introduction

• Opton 20 is a medicine which reduces the amount of acid produced in your stomach. It is used to treat heartburn, acid reflux and problems in your food pipe. It is also used to prevent and treat stomach ulcers. You should take Opton 20 as your doctor advises. The dose will depend on what you are being treated for, but it should be the lowest dose for the shortest amount of time needed to treat your condition. Normally it should be swallowed whole about an hour before a meal and at the same time each day. It may take up to a few weeks to work properly but your doctor will tell you how long you need to be taking it for. You should keep on taking it as prescribed even if your symptoms disappear quickly. If you are taking this medicine for a long time, your doctor may carry out regular tests to check your levels of magnesium which can fall with this medicine. Common side effects include headache, constipation or diarrhoea, stomach pain and feeling or being sick. These tend to be mild but talk to your doctor if they bother you or do not go away. The risk of side effects may increase the longer you take this medicine. Serious side effects are rare, but some need immediate medical attention. Ask your doctor what these are. You may be more likely to have a broken bone if you take it for a long time. It is best to avoid foods that seem to make your symptoms worse, such as rich, spicy and fatty foods. It also helps to cut down on caffeinated drinks, such as tea, coffee and cola, as well as alcohol. Opton 20 is not suitable for some people. Before taking this medicine, you need to tell your doctor if you have severe liver problems, are taking medicines for HIV, have had an allergic reaction to similar medicines in the past or have osteoporosis. Alcohol does not interfere with the way Opton 20 works. However, drinking alcohol makes your stomach produce more acid than normal. This medicine can make you feel dizzy, sleepy, or affect your vision. If this happens, do not drive, cycle or use machinery or tools until you feel better. It is not usually recommended during pregnancy and breastfeeding.

Precaution

• Paediatric; pregnancy, lactation. Malignancy and hepatic impairment. Increased risk of developing certain infections such as community-acquired pneumonia. For patients with severe liver impairment, a dose of 20 mg should not be exceeded. Lactation Risk Summary Esomeprazole is the S-isomer of omeprazole and limited data suggest that omeprazole may be present in human milk. There are no clinical data on the effects of esomeprazole on the breastfed infant or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Esomeprazole and any potential adverse effects on the breastfed infant from Esomeprazole or from the underlying maternal condition.

Interaction

• Increased risk of digoxin-induced cardiotoxic effects. Increased risk of hypomagnesaemia w/ diuretics. May increase INR and prothrombin time w/ warfarin. May increase serum concentration of tacrolimus, saquinavir, methotrexate. May interfere the elimination of drugs metabolised by CYP2C19 (e.g. diazepam). May decrease the bioavailability of ketoconazole, erlotinib and Fe salts. Potentially Fatal: May decrease serum concentration and pharmacological effects of rilpivirine, atazanavir and nelfinavir.
