How do you pronounce 医歯薬?

[watermen]

How do you pronounce 医歯薬? I know the individual kanji pronunciation, but when these 3 individual come together, how do you pronounce it.

This is actually the name for this dictionary.

That would be いしやく, and it's the name of a publishing company. I've been on the lookout for a medical dictionary and now I finally have access to one. Yay.
