A member asked:

How long does it take to find out if your allergic to digestive enzyme supplements?

A doctor has provided 1 answer

The time frame for the development of an allergic reaction to any substance is highly variable and can be within days,weeks,months or years of taking the substance. I have seen allergic reactions the first day a person has taken a new medication presumably from a cross reaction to another medication taken in the past.Last one was after taking the first dose of the antiCovid medication, Paxlovid
