ZAVESCA can provide benefits to people with type 1 Gaucher disease. Still, keep in mind that ZAVESCA may take some time to work in ways you can notice.

To make the most of ZAVESCA therapy, you and your doctor may want to consider making some changes to your diet.

In people with type 1 Gaucher disease, the body has an excess of fatty substances called glycosphingolipids (gli-coh-sfing-goh-lip-ids).1 These fatty substances are harmful when they build up in cells.1 ZAVESCA® (miglustat) works by limiting the body's production of these fatty substances.2
Just as it limits overproduction of these fatty substances, ZAVESCA may also limit how the body digests carbohydrates.2,3 Carbohydrates are found in grains, bread, rice, and flour. Simple sugars, found in things like soda, cookies, or desserts, are also carbohydrates. ZAVESCA may affect how long carbohydrates stay in the intestines, so carbohydrates may be digested more slowly than normal and can cause diarrhea and gas.2,4
Diarrhea is common with ZAVESCA and sometimes can be serious. Diarrhea appears to be the result of the effect of ZAVESCA on the body's digestion of carbohydrates.
While many people who take ZAVESCA may get gas, loose stools, or diarrhea, diarrhea decreased over time with continued ZAVESCA treatment, and may respond to individualized diet modification (e.g., reduction of sucrose, lactose, and other carbohydrate intake), to taking ZAVESCA between meals, and/or to anti-diarrheal medications, most commonly loperamide. Patients may be instructed to avoid high-carbohydrate foods during treatment with ZAVESCA if they present with diarrhea.2
Taking the simple step of reducing carbohydrates in the diet may help manage these side effects.
Talk to your doctor or a dietitian to see what may work best. Make certain to follow the doctor's directions about how to take ZAVESCA.
Other considerations
- Eating small healthy snacks between meals, especially if weight loss is a concern.
- Taking ZAVESCA® (miglustat) at the same time each day—for instance, if your prescription is for ZAVESCA 3 times a day, then take it when you first wake up, in the early afternoon, and before going to bed (or as close to 8-hour intervals as possible).
- Taking ZAVESCA with or without food. Some people experience fewer side effects when taking ZAVESCA without food, while others see the opposite effect. Discuss with your doctor what works best for you.
- It's important to remember that different people react to ZAVESCA in different ways. After being on ZAVESCA for a month, you may be able to slowly bring certain foods back into your diet as your body adjusts to therapy with ZAVESCA. Work with your doctor to talk about when the time might be right for you.
Talk to your doctor about your diet or about taking an anti-diarrheal medication if diarrhea is a problem for you.2
