Product introduction
Omrok 20mg Tablet is a medicine that helps reduce the amount of acid made by the stomach. It is used for the treatment of peptic ulcer, gastric ulcer, gastroesophageal reflux disease (GERD), and for the management of Zollinger-Ellison syndrome, a rare condition in which the stomach produces too much acid.
Take Omrok 20mg Tablet exactly as directed by your doctor, usually once daily before a meal. Swallow it whole; do not chew or crush it. To get the most benefit, take it regularly at the same time each day. Continue the full course even if you feel better, as stopping too soon may cause symptoms to return. Along with treatment, avoid irritants such as alcohol, tobacco, and spicy or acidic foods. Eat smaller, more frequent meals and do not lie down immediately after eating.
The most common side effects include headache, stomach pain, nausea, diarrhea, vomiting, and gas. These are generally mild and often go away as your body adjusts to the medicine. If diarrhea is severe, persistent, or watery, inform your doctor. Staying hydrated and maintaining a balanced diet can help reduce discomfort.
Before taking this medicine, tell your doctor if you have liver disease or any kidney problems. Long-term or high-dose use may increase the risk of bone fractures, low vitamin B12 or magnesium levels, or fundic gland polyps in the stomach. Therefore, the medicine should be used at the lowest effective dose for the shortest possible time. Seek immediate help if you notice signs of severe allergic reaction, such as swelling, breathing difficulty, or rash with blisters. Do not take Omrok 20mg Tablet if you are allergic to omeprazole or any ingredients in the medicine. Inform your doctor about all other medicines you take, as Omrok 20mg Tablet can affect how other medicines work.
