Actavis to use Allergan name after $66bn takeover

Actavis, which began as a small New Jersey-based generic pill-maker called Watson Pharma, will take the name Allergan after agreeing to buy its new namesake in the drug industry’s largest deal of last year.

The newly-named company will still be based in Dublin, with operational headquarters in Parsippany, New Jersey.

It will sell brand products under Allergan’s name, while using Actavis in some markets.
