What is Miglustat used for?
Miglustat is used in rare lysosomal storage disorders that involve glycosphingolipid accumulation.
- Gaucher disease type 1: reduces glucosylceramide buildup, helping to improve hematologic parameters and organ size. - Niemann‑Pick disease type C: decreases glycosphingolipid synthesis, supporting neurological function and slowing disease progression.
What are the side effects of Miglustat?
Adverse reactions may vary in frequency and severity.
Common Side Effects: - Diarrhea: loose stools occurring during treatment. - Nausea: feeling of sickness or urge to vomit. - Weight loss: gradual reduction in body weight. - Abdominal pain: discomfort in the stomach area. - Flatulence: increased gas production. - Headache: mild to moderate head pain.

What precautions apply to Miglustat?
Before initiating therapy, clinicians should consider several safety measures.
- Liver monitoring: assess hepatic function periodically. - Blood glucose: monitor for hypoglycemia, especially in diabetic patients. - Gastrointestinal tolerance: evaluate for persistent diarrhea or nausea. - Psychiatric assessment: watch for signs of depression or mood disorders. - Hypersensitivity: discontinue if severe allergic reactions develop. - Store at below 25°C: keep in the original pack, protect from moisture.
What does Miglustat interact with?
Miglustat may interact with other medicines that affect its metabolism or exacerbate side effects.
Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole): may increase miglustat exposure. - Strong CYP3A4 inducers (e.g., rifampicin): may reduce miglustat efficacy.
