All the posts about trouble getting hyoscyamine worried me so I went to my pharmacy to see what was going on. My pharmacist told me that some generic hyoscyamine was recalled not too long ago. He told me they had plenty but he hadn't had to order any in a while. When I asked him to refill my prescription, he discovered that the hyo I had at home, from April, was from the recall. He then quickly explained that it wasn't a patient recall so someone had determined it was safe. He had no idea why it would be recalled from pharmacies but not from patients. Apparently this happens occasionally but we never hear about it.
My refill today was from a different manufacturer. It's a generic sublingual.
