Novartis pharmaceuticals
Novartis UK confirms that we will go out of stock on ESTRADOT TTS-50, ESTRADOT TTS-100, and ESTRADOT TTS-25. Based on our current information, we expect that these presentations of Estradot will start to go out of stock from January 10, with supplies returning to normal levels within four weeks. Supplies of ESTRADOT TTS-37.5 are unaffected.
Novartis has responded to the significant and sustained growth in demand for Estradot by increasing production three-fold from 2019 to the present day. Despite expanding supply, we have capacity constraints within the manufacturing plant, which we are working hard to resolve. In addition, other HRT suppliers are having supply difficulties, which has increased the demand for Estradot.
We understand shortages such as these can cause great uncertainty for patients, and we are working hard to resolve this matter as quickly as possible. We have notified the Department of Health who are working with us to look at alternative solutions in the interim.
We encourage any patient affected by this shortage to speak with their doctor or pharmacist for information on available alternative options during this period.
