General Information



Product introduction
L SO 30mg Injection is also used to prevent stress ulcers in seriously ill patients and is administered before anesthetic medication to help prevent aspiration-related complications. It belongs to a class of medicines known as proton pump inhibitors (PPIs). This medicine is administered into a vein by a healthcare professional and will only be given to you if your doctor thinks that an injection is more suitable for you at the moment than a tablet. The dose will depend on your underlying condition and how you respond to the medicine. Your doctor will decide the duration of treatment but you should keep on taking it as prescribed, even if your symptoms disappear quickly. You can increase the efficiency of the treatment by eating smaller meals more often and avoiding caffeinated drinks (like tea and coffee), and spicy or fatty foods.
The most common side effects observed with this medicine include nausea, vomiting, headache, flatulence, diarrhea, and pain in the injection site. These symptoms are generally mild but if they bother you or do not go away, consult your doctor. Long-term use of this medicine may lead to an increased risk of side effects. For instance, using this medicine for more than 1 year may increase your risk for bone fractures, especially with higher doses. Talk to your doctor about ways to prevent bone loss (osteoporosis), like taking calcium and vitamin D supplements.
L SO 30mg Injection 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 ever had an allergic reaction to similar medicines in the past, or suffer from bone loss (osteoporosis). Pregnant or breastfeeding women should also consult their doctor before taking it. Avoid drinking alcohol as it makes your stomach produce excessive acid and can worsen your symptoms. Do not drive or use machinery or tools, if this medicine makes you feel dizzy or sleepy.
Uses of L SO Injection
- Acidity
- Gastroesophageal reflux disease (Acid reflux)
- Peptic ulcer disease
Benefits of L SO Injection
Acidity occurs when excess stomach acid causes symptoms like heartburn, sour taste, and stomach discomfort. L SO 30mg Injection helps reduce the amount of acid produced in the stomach, relieving symptoms and promoting digestive comfort.
Gastroesophageal reflux disease (GERD) is a condition where stomach acid frequently flows back into the food pipe, causing heartburn, chest discomfort, and sometimes throat irritation. L SO 30mg Injection reduces acid production, helping prevent acid reflux, ease symptoms, and protect the lining of the food pipe from damage.
Peptic ulcer disease involves painful sores in the stomach or upper intestine lining caused by excess acid or infection. L SO 30mg Injection helps heal these ulcers by reducing stomach acid and creating a favorable environment for recovery, relieving pain, and preventing ulcer recurrence.
