Over the last few months demand for Oestrogel and Sandrena has increased significantly across the UK leading to occasional shortages.
HRT manufacturers are increasing production so they can satisfy orders for all of their patients across the UK.
Unfortunately availability is not predictable and it often depends on what the pharmacy / dispensary is able to access from one day to the next.
There are other HRT medicines which can be prescribed if your usual one is temporarily unavailable. Please contact the surgery about these options if you are close to running out.
