Terms of use

By using this site you agree to these plain-language terms. They describe current practice and may change; when it does, the “updated” date above will move.

General information only

Content is for general information. It is not medical advice, and it may be out of date. Check the date on each page and the retailer’s or maker’s current listing before you buy. See the medical and legal disclaimer.

Accuracy

We work from cited sources and aim to be accurate, but we cannot promise that every page is complete or current. If you find an error, tell us through the contact page; see the corrections policy.
