Inpan 40mg Injection is a medicine that reduces the amount of acid produced in your stomach. It is used for treating acid-related diseases of the stomach and intestine such as acid reflux, indigestion, peptic ulcer disease, and some other stomach conditions associated with excessive acid production. Inpan 40mg 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, dizziness, flatulence, diarrhea, stomach pain, and thrombophlebitis (pain, redness, and swelling of the vein). 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. Inpan 40mg 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.
