Sulfite-containing Canadian pharmaceutical products available in 1991.

OBJECTIVE

To compile an inclusive list of Canadian pharmaceutical products available in 1991 that contained sulfites.

DATA SOURCES

Written and oral responses from 94 pharmaceutical companies selected from the 1989 Compendium of Pharmaceuticals and Specialties.

RESULTS

A list of sulfite-containing pharmaceutical products was compiled from data supplied by the 90 responding companies. Companies whose products contained no sulfites were separately identified.

CONCLUSIONS

Sulfites are present in many pharmaceutical products and are one of many excipients and additives that have been reported to cause severe adverse reactions. The provided list should be a useful aid for health care practitioners when prescribing pharmaceutical products for sulfite-sensitive patients.
