What is lactulose made of (its ingredients)?
Lactulose is a synthetic sugar (a non-digestible disaccharide) made of two simple sugar units: galactose and fructose. In other words, its active ingredient is lactulose itself.
What “inactive ingredients” can be in lactulose syrups or solutions?
In lactulose products (like oral syrups), the label commonly includes the lactulose active ingredient plus added materials used to make the medicine stable and easier to take (for example, sweeteners, flavorings, and/or preservatives). Exact inactive ingredients vary by manufacturer and product strength, so you need the specific product’s “Inactive ingredients” section on the package or prescribing information.
Is lactulose an ingredient in other products?
Yes. Lactulose can also appear as an ingredient in combination medicines, but the key point is that lactulose’s own composition is the galactose–fructose sugar called lactulose.
What should you check if you have dietary restrictions or allergies?
Because lactulose products can include additional excipients beyond lactulose, the most important ingredient-related check is the full ingredient list on the specific brand you have—especially if you avoid certain sweeteners, sugars, preservatives, or if you have allergy concerns.
Where to confirm the ingredient list for your exact brand
If you share the brand name (and strength, such as mg/mL or % w/v) or a photo of the ingredient panel, I can help interpret it. You can also verify product-specific ingredient listings in the official prescribing information or the package insert.
