Is the word remédios the same in Brazilian and European Portuguese?

Yes

The spelling, grammar, and meaning of "remédios" are identical in both Brazilian and Continental Portuguese. The only difference is in pronunciation. In Brazilian Portuguese, vowels are generally more open and clearly articulated. In Continental Portuguese, the language features "vowel reduction," meaning unstressed vowels (like the 'e' in remédios) are much more closed, muffled, or even nearly silent depending on the regional accent.

Brazilian Portuguese Examples

3. Não tem remédio para essa tristeza. (There is no remedy for this sadness.)
