ترجمة - هولندي-يونانيّ - voor vaginale toediening

AspieBrain is this refering to a medicine?

Yes, I assume it is for a medicine, douche or instyructions for condome use, or something in that general direction. There is no additional information to specify.

So if it is about a medicine i think it's better to translate it "για κολπική χρήση"

ΟΚ I do agree that it sounds better "για κολπική χρήση" but it assumes that whatever the product is will be used by the person self...

Will it sound just as correct if it is for an object (like a condom) or instrument (like a vibrator) etc that someone else might be using?

If you agree that it sounds better and covers both possibilities then by all means let's change it to "για κολπική χρήση"

Sorry if I seem to overkill the issue here. Thanks!

yes "για κολπική χρήση" can be used in both situations and it sounds more scientific... well it's an important instruction wherever it refers so you are right to get to the bottom of it
Thanks for helping me with that

awww! blushing :-)
