Is it really true that using Tylenol regularly increases the chances of adults developing Asthma in women by about 50%? I am worried as I am already allergic to a hell of a lot of skin and ecological allergies and also a past account of incessant intake of Tylenol in those years long before it was connected to liver damage and loss of hearing. I had been of Tylenol for more than a decade and started taking it again only when I had the pain of endometriosis last November. And now to top it off I have contracted Asthma also! Is it very common for middle aged women to develop asthma? And do you think that there is a connection between Tylenol and asthma?? Any clues anyone??
