Can Nuvan Prostrips be re-used ?
Nuvan Prostrips are only effective for up to 4 months. Once that time period has passed, they will no longer be as effective as they were when they were first opened. We recommend changing them out every 4 months to make sure you are getting maximum performance out of the product. Please read the product label for further information.
