You can cut a lower dose patch into smaller pieces to achieve your specific dose (eg, if your usual dose is a 25mcg patch, the pharmacist can give you a 50mcg patch to cut in half, or a 100mcg patch to cut into quarters). Although it can be fiddly, this is ok to do. All of the patches used in NZ are matrix type patches, which means the drug is evenly distributed throughout the patch so it is ok to cut them to achieve a smaller dose. It's best to store the remaining portion of the patch in a small zip-lock bag to make sure it doesn't lose its effects, before you are ready to apply it. One study* showed that cut estradiol patches remain stable for up to 1 month if they are stored in an airtight plastic bag at room temperature. *REF: Ankarberg-Lindgren C, et al. 2019;8(4):360
