Nitrofurantoin macrocrystals (commonly known as nitrofurantoin-macro) typically have a shelf life of about 2 to 3 years when stored properly in a cool, dry place. It's important to check the expiration date on the packaging, as the effectiveness of the medication can diminish after this date. Always consult a healthcare professional if you have questions about using medications beyond their expiration date.
