Frequently asked questions about SLOS, treatment, and more


What is Smith-Lemli-Opitz Syndrome (SLOS)?

SLOS results from an autosomal recessive mutation on the 7-dehydrocholesterol reductase (DHCR7) gene involved in cholesterol production and disrupts the body’s ability to make cholesterol.

In patients with SLOS:

  • Low levels of cholesterol are produced and absorbed by the body.
  • Because bile acids are made from cholesterol, a person with SLOS with very low cholesterol levels cannot make a sufficient amount of bile acids, potentially leading to a bile acid deficiency.
  • Without sufficient bile acids present, patients cannot properly absorb cholesterol and other nutrients.

Low levels of cholesterol production and absorption may ultimately lead to poor nutrition and poor growth.

What are bile acids, and why are they important?

Bile acids are essential for the absorption of fats and fat-soluble vitamins and nutrients in the intestines. Without sufficient bile acids present, patients cannot properly absorb cholesterol and other nutrients.

Also, bile acids help digest dietary cholesterol from the intestine. Low bile acids levels likely prevent dietary cholesterol from being absorbed properly and contribute to the cholesterol deficiency seen in SLOS.

Two key bile acids necessary for proper digestion, absorption, and toxin removal are:

  • Cholic acid
  • Chenodeoxycholic acid

Abnormal bile flow or production can result in:

  • Poor absorption of vital nutrients.
  • Accumulation of toxic materials in the body.

How is SLOS treated?

Currently, there is no cure for patients with SLOS. However, there are ways to help support your child and manage his or her symptoms. Current treatments can help with symptoms and do not cure the disease. SLOS is caused by a defect in one of the genes involved in cholesterol production. Bile acids are not made correctly in patients with SLOS, and bile acid replacement therapy may help people with SLOS by increasing their cholesterol levels and cholesterol absorption, lowering their liver enzymes, and may even increase their height and weight.

CHOLBAM® (cholic acid) capsules is an adjunctive, replacement therapy that prevents the buildup of abnormal bile acids that occur in patients who have liver involvement in SLOS. Learn about treating SLOS.


What is CHOLBAM® (cholic acid) capsules?

CHOLBAM® is a bile replacement medication that is taken by mouth. CHOLBAM® is indicated for:

  • Patients with bile acid synthesis disorders due to single enzyme defects.
  • Adjunctive treatment of peroxisomal disorders, including Zellweger spectrum disorders, in patients who show signs and symptoms of liver disease, steatorrhea (fatty stools), or complications from decreased fat-soluble vitamin absorption (A, D, E, K).

The safety and effectiveness of CHOLBAM® on symptoms outside the liver have not been studied.


How is CHOLBAM® taken?

CHOLBAM® is taken by mouth each day. It is recommended to take CHOLBAM® with food. Do not crush or chew capsules. If your child or loved one is unable to swallow capsules, talk to your doctor for instructions on how to take CHOLBAM®. CHOLBAM® is available in 50 mg and 250 mg capsules.


How to access CHOLBAM®?

Getting CHOLBAM® is simple through the Total Care HUB. Download the enrollment form today and talk to your doctor about getting started.


How is CHOLBAM® administered?

CHOLBAM® can be taken in 2 different ways:

  1. The capsule can be swallowed,
  2. The capsule can be opened and its contents can be mixed with liquid/food.


Which doctor should I discuss CHOLBAM® with?

Your geneticist, pediatrician, or gastroenterologist will be the most likely doctor to understand how CHOLBAM® therapy works in patients with SLOS. If you are not routinely seeing one of these specialists, feel free to talk to any doctor you see frequently .


Can I get CHOLBAM® at a local pharmacy?

CHOLBAM® is not dispensed at retail pharmacies. CHOLBAM® can only be distributed from Travere’s Specialty Pharmacy partner, Eversana, via the CHOLBAM® Total Care HUB. The HUB is a comprehensive support program for patients who have been prescribed CHOLBAM® and their caregivers. When you enroll in the program, a dedicated HUB Counselor will be assigned to you.


Is CHOLBAM® safe?

As with any medication, there is a possibility of side effects. In clinical studies, the most common side effect in about 2% of patients taking CHOLBAM® was diarrhea. All other side effects were less than or equal to 1% of patients.

Call your doctor right away if there is:

  • Yellowing of the skin or whites of the eyes.
  • Dark or brown (tea-colored) urine.
  • Pain on the right side of the stomach.
  • Bleeding or bruising that occurs more easily than normal.
  • Increased tiredness.

Discuss any side effects that concern you with your doctor.

Why is it important to take CHOLBAM® every day?

It’s important to take CHOLBAM® every day to help keep the normal balance of bile acids in the liver. Avoid missing doses and do not stop therapy without talking with your doctor.

How often should people taking CHOLBAM® see their doctor?

People taking CHOLBAM® should see their doctor regularly to be sure CHOLBAM® is working properly. Your child’s or loved one’s doctor will monitor liver function with appropriate tests every month for the first 3 months, every 3 months for the next 9 months, every 6 months for the next 3 years, and annually thereafter. The doctor may discontinue CHOLBAM® therapy if liver function does not improve within 3 months of starting treatment, if complete biliary obstruction develops, or if signs or symptoms of worsening liver function or cholestasis appear.

Why does the dosage change?

The amount of medication may change as weight changes. Be sure to monitor this carefully and have your child’s or loved one’s doctor adjust as needed, particularly during periods of rapid growth.
