I'm gathering information regarding ISMP Best Practice 6: Our facility uses glacial acetic acid to conduct stability testing within the pharmacy and I'm told that there is no alternative product that can be used. Do any other facilities conduct stability testing within the pharmacy as well? If so, do you use glacial acetic acid to do so, or some other product-what is that product? If you do use glacial acetic acid, what safeguards do you have in place to prevent errors?
