Individuals with Congenital Sucrase-Isomaltase Deficiency (CSID) must be aware of the starch and sucrose content in medications. Many common medications contain sucrose and starch, especially liquid medications. One particular medication is liquid amoxicillin, a frequently prescribed antibiotic for children. There are safe alternatives and the need for sucrose-free and starch-free medications should be discussed with your physician and pharmacist. You should always check ingredient lists carefully. Some compounding pharmacies have the capability to make medications that are sucrose-free and starch-free, but it is important to request this special composition.
