US pharmaceutical company Allergan has announced a major expansion of its botox facility in Westport in Co Mayo, with the creation of 200 new jobs.

Speaking at the plant this morning, Taoiseach Enda Kenny said this development would provide a major boost for the region, bringing further high quality jobs to the west of Ireland.

Allergan currently employs over 800 people in Westport where it manufactures and develops a range of medical devices and pharmaceutical products, the best known of which is botox.

The US multinational is now investing $350m in a new botox facility at its Westport site. The managing director of Allergan, Pat O'Donnell, said that with the help of the IDA, the company had acquired the technology park adjacent to the plant to meet the growing demand for the product.

In addition to cosmetic treatments, the use of botox to treat medical conditions is on the increase. The Irish Medicines Board has recently approved the use of botox in treating urinary problems and chronic migraine symptoms.

The 200 new jobs at Allergan will come on stream over the next four years. A further 250 jobs are expected to be created locally when construction work on the new facility begins later in the year.

And new 100 technology jobs have been announced by the multinational management consultants Accenture.

The positions are targeted for both graduates and those with industry experience and will be based around the country.

These jobs are on top of an earlier four-year programme to recruit 100 staff announced in November at a research and innovation centre it was establishing. Accenture already employs more than 1,300 people in Ireland.

Accenture, a company to which other business look to for management and technology services and outsourcing, has a global workforce of more than 240,000.

Its international client list includes a majority of Fortune 500 companies, and in Ireland they work with Microsoft, Kerry Group and the Revenue Commissioners amongst others. Recently, Accenture moved its corporate headquarters to Ireland from Bermuda.
