JERUSALEM, Jan 29 (Reuters) - Teva Pharmaceutical

Industries is not overly concerned about U.S.

President Donald Trump potentially imposing tariffs on drugs

since many medicines are already made in the United States, its

chief executive said on Wednesday.

Tariffs "may take time to come to this sector because if you

stop pharmaceuticals from abroad, you have to have them made in

the U.S. to make a substitution," Teva CEO Richard Francis told

Reuters after the Israeli drugmaker issued fourth-quarter

results.
