Promethazine brands?

The most well-known brand is Phenergan (promethazine HCl). There is also a combination product commonly seen as Phenergan with Codeine (promethazine plus codeine).

Brand availability varies by country, and many markets sell promethazine mainly as a generic under local brand names. If you tell me your country (and whether you want single-ingredient promethazine or the codeine-containing combo), I can list the current brand names used there.
