What Kind of Medicine is Naloxegol?
Simply put, Naloxegol is a prescription medicine given to treat constipation caused by powerful pain medicines called opioids. Think about how opioid painkillers work in your body. They reduce your pain signals, but they also slow down the natural movement of your gut.
This means the muscles in your bowels squeeze much slower than normal, making it hard to pass stool. Naloxegol acts as a direct solution to this exact problem. It belongs to a group of medicines known as opioid blockers.
The special feature of Naloxegol is that it mainly works right inside your gut. It does not block the pain relief working in your brain. Instead, it travels to your intestines, blocks the pain medicine from slowing down your gut, and helps your gut muscles move normally again.
Things You Must Tell Your Doctor Before Taking This Medicine
Before you start taking Naloxegol, giving your doctor a complete picture of your health history is very important. Always let your doctor know if you have any of the following medical conditions:
- You have a tumor or cancer in your stomach or bowels.
- You suffer from a condition called diverticulitis.
- You have a history of a blocked bowel in the past.
- You have an inflammatory bowel disease like Crohn disease or ulcerative colitis.
- You live with kidney disease or liver disease.
- You had recent surgery on your stomach or intestines.
- You are receiving cancer treatment with medicines like bevacizumab.
- You have allergies to Naloxegol, other medicines, foods, or dyes.
- You are pregnant, trying to get pregnant, or breastfeeding.
Your doctor uses this important health information to decide if Naloxegol is safe and suitable for your specific situation.
How Should You Use This Medicine Correctly?
To get the best results from your treatment, taking your medicine exactly as prescribed is essential. Follow these simple steps for safe use:
- Timing: Take this tablet only once a day on an empty stomach. Take it at least one hour before your first meal of the day, or at least two hours after your meal.
- How to Take It: Swallow the tablet whole with a glass of water. Do not crush, chew, or cut the tablet. If you struggle to swallow pills, ask your doctor if you can crush it, mix it with water, and drink it right away.
- Other Laxatives: Do not use extra laxatives unless your doctor specifically tells you to do so. If you still have no relief after three days, talk to your doctor about adjusting your plan.
- Important Rule: If you stop taking your opioid pain medicine, you must also stop taking Naloxegol right away. This medicine is only meant to treat constipation caused by those specific pain drugs.
What Happens If You Take Too Much?
If you think you have taken too much of this medicine, do not panic. Call your local emergency services or poison control center right away. In the US or Canada, call 911. In the UK, call 999. You can also go straight to the nearest hospital emergency department.
