Does lactulose cause dry mouth or throat

[Poobah]

Do you mean the lactose in dry powder inhalers? It's important to rinse thoroughly after DPI use. Lactose is a sugar (from milk) and is used to coat particles of medicine. Sugars can cause thrush as the fungal infection will feed off the sugars - it looks like a white coating on the tongue and can cause spots in the mouth and throat. So oral hygiene is very important. I always brush my teeth and gargle with Listerine after DPI use, but salt water may do the trick. Some medicines do dry the mouth too, so it's important to keep well hydrated. The accompanying patient leaflet to the medicine will give advice.

Do you mean lactulose (which is a medication used to help relieve constipation) or lactose which is, as Poobah has explained, a sugar used in dry powder inhalers?

As it happens I’ve used both. I can tell you that I’ve never known lactulose to give me a dry mouth and throat. Dry powder inhalers, on the other hand, have done. As Poobah also said, it is very important to gargle and rinse out (I also clean my teeth) after using any preventer inhaler, but particularly so with the dry powder versions.
