Sometimes, some of the diseases that our children suffer from are very complex. And the medicines given for them are also special. Today we are going to talk about one such special medicine. This medicine is called Odevixibat, which is given to some children to treat unbearable skin itching caused by a rare liver disease. If your child has been prescribed this medicine by the doctor, then this article will be very important for you.
What kind of medicine is Odevixibat?
Simply put, Odevixibat is a medicine that is given to control excessive itching caused by a problem with your child's liver. It is known by the market name Bylvay.
Medically speaking, this belongs to a class of drugs called ileal bile acid transporter (IBAT) inhibitors . This means that this medicine controls the reabsorption of bile acids in our intestines into the body.
This medicine is mainly used to control itching in patients with a condition called Progressive Familial Intrahepatic Cholestasis (PFIC) . PFIC is a rare genetic condition that interferes with the flow of bile from liver cells. This causes bile to build up in the body, causing unbearable itching. Odevixibat works by controlling the underlying cause of the itching.
Things you need to tell your doctor before starting medication
Before using this medicine, it is important to give your doctor a complete description of your or your child's health condition. Be sure to mention the following in particular:
- Vitamin deficiencies: If a doctor has told you that you have low levels of vitamins A, D, E, or K in your blood, tell them.
- Pregnancy: If you are pregnant, or are planning to have a baby in the near future, you should tell your doctor.
- If you are a breastfeeding mother: If you are a breastfeeding mother, be sure to inform the nurse.
Talking to the doctor without hiding this kind of information is very important for your and your child's safety.
