Doctors will formulate individualized dosages based on the patient's weight, disease severity and efficacy feedback. A common starting dose is 40micrograms/kg of body weight per day. Some patients may gradually adjust to 120micrograms/kg per day, but not more than 6mg per day.

Orvitixibate may affect the absorption of certain drugs or nutrients, especially fat-soluble vitamins (such as vitamins A, D, E, K) and bile acid binders (such as cholestyramine). Therefore, if these drugs are being used concurrently, the dosing time of orvixibat should be staggered by at least 4 hours to avoid weakening of drug efficacy or occurrence of malabsorption. At the same time, patients should proactively report to their doctors all drugs they are using, including Chinese patent medicines or nutritional supplements, to avoid potential drug interactions.

3. Common adverse reactions during medication and how to deal with them

The most common adverse reaction of orvixibat is diarrhea, which is mainly related to its blocking of bile salt reabsorption and increasing the concentration of bile acids in the intestinal lumen. Diarrhea in most patients occurs in the early stages of medication, and the symptoms are mild and can be relieved by adjusting the diet (reducing fat intake) or using antidiarrheal drugs under the guidance of a doctor. If diarrhea continues to worsen, you need to seek medical advice promptly to evaluate whether to adjust the dose or suspend medication. In addition, some patients may also experience gastrointestinal symptoms such as abdominal pain, nausea, bloating, and loss of appetite, most of which are transient reactions.

In individual cases, fluctuations in liver function, such as elevated transaminases, may occur. Therefore, liver function and serum total bile acid levels need to be checked regularly during the medication period to keep abreast of the efficacy and possible side effects. Once signs of liver damage such as yellowing of the skin, deepening of urine, and significant loss of appetite appear, you should seek medical attention as soon as possible. The doctor will decide whether the treatment plan needs to be adjusted based on the examination results.

If the patient is planning to become pregnant, he should communicate with his doctor in advance and make appropriate arrangements. If you plan to become pregnant during treatment, you must use effective contraceptive measures. Whether to continue taking medication during breastfeeding should be made by the doctor on an individual basis based on the severity of the condition and the health risks to the baby.

Therefore, patients need to be patient and insist on returning to the hospital for follow-up consultations on time. During the follow-up process, doctors will gradually optimize the treatment plan based on changes in bile acids, degree of symptom relief, and adverse reactions. If the long-term control of the disease is unsatisfactory, doctors will also consider whether other treatments or liver transplantation are needed.

7. Drug storage and management

Odevixibat is a prescription drug and should be stored properly to prevent children from accidentally taking it. Drugs should be stored in a dry, cool place away from direct sunlight.
