The supply of Eugenol (levothyroxine sodium tablets) in China has recently become tight, mainly due to problems in the supply channel as a result of the long inspection time for imported drugs. The production and sales of this product are crucial to thyroid patients worldwide. Therefore, the manufacturer is currently striving to ensure the supply to tertiary hospitals in all regions and will continue to mobilize all parties to communicate with customs to make the drug testing and release process smoother in order to meet the needs of all patients. At present, all provincial, city and state level hospital pharmacies are guaranteed to supply, and according to the manufacturer, it is expected that the drug will be gradually released and put back on sale in pharmacies at all levels after the Spring Festival in 2016. Therefore, please do not worry, and do not rush to buy or more open stock. Because the drugs have an expiration date, usually about 2 years, so be sure to store and use as needed.
