Do Cough Drops Break a Fast? It Depends

Reviewed by the FastTrack team · Updated June 2026
Short answer: It depends

It depends on the drop. Regular cough drops carry about 10 to 17 calories each, mostly sugar, so a few of them end a strict fast. Sugar-free drops such as Halls Sugar Free have about 5 calories from isomalt and are fine for most fasts.

Why regular drops count

A regular Halls has roughly 2 to 3 g of sugar or glucose syrup, and a Ricola original about 3 to 4 g. One drop is minor, yet people with a sore throat often take one every hour, which can add 100 calories of sugar over a day.

Sugar-free drops and sugar alcohols

Sugar-free drops use isomalt, sorbitol or sucralose. Isomalt is only partly absorbed, so the calories are low and the effect on blood sugar is small. Several sugar-free drops a day can upset the stomach, a common effect of sugar alcohols.

How much is safe

When you are sick, choose sugar-free drops and use them as the label says. If you feel unwell enough to need many drops, it is also a good day to eat normally.

Can I fast when I have a cold?
You can, but there is no benefit in pushing through. Eating and drinking well often helps you recover, and the fast can wait.
