I was prescribed Hyoscyamine for bladder spams this morning. I have host of medical issues such as: Glaumona, Hiatus Hernia, acid reflux, COPD, Asthma,Moderate to severe lung problems, thyroid issues, a list of reactions to a long, long list of medications. I have not taken a one of these pills yet and I am reluctant to start!!! I am also allergic to Sulfa medications. What do I do? The doctor I seen this morning I ve only seen 4 times in all. Ruth Ann
