Can one who has a throat problem use a liquid spray while fasting to relieve the situation?

Question:

Can one who has a throat problem (dryness of the throat) use a liquid spray while fasting to relieve the situation?

Answer:

If the liquid goes down to the digestive system, then it invalidates the fast. If the situation would otherwise be haraj (harmful) or Zarar (considerably awkward), they can use it but their fast is invalid.
