Importing Metformin to Japan

These include having a valid prescription and carrying no more than a 30-day supply of the medication.
For longer stays or if you need more than a 30-day supply, you may need to apply for a Yakkan Shoumei (Drug Import Certificate) from the PMDA.

However, the process can be time-consuming, so it's advisable to plan ahead and consult with your healthcare provider before traveling.

It's important to discuss these options with your healthcare provider in Japan to determine the best course of treatment for your specific needs. They can help you understand the benefits and risks of each medication and guide you in making an informed decision.
