The shortage of hormone replacement therapy (HRT) in Northern Ireland is distressing for women and challenging for pharmacies trying to access it, according to a community pharmacist.

Let you study it first, what sort of sorts it is to get ทางเข้าเกม a lot of money. Sort of like this, earning a little money, it depends on when we play, whether there's any luck on our side. 

Loretto McManus advised women to leave plenty of time for ordering their prescriptions.

The Health and Social Care Board said there were "some treatments which are currently experiencing supply issues".

HRT helps many women control their often difficult menopausal symptoms.

There is a national shortage of HRT with officials citing several reasons including manufacturing delays, an increase in demand and possibly Brexit.

Ms McManus said certain products were out of stock in pharmacies across Northern Ireland and that this was "distressing" for women who have become used to particular treatments.

"As a community pharmacist the utmost care of our patients is premium to us," she said.

"Trying to source the prescribed product in a timely manner for the patient can be challenging.

"Sometimes that product won't be available and unfortunately this is not in the control of the community pharmacy. It can be a manufacturing problem, so we have to keep our communication channels open with a GP and liaise with them."

Several women have told BBC News NI that they were being offered substitutes or had to source the medication themselves.
