Prefixes are additional letters or numbers at the front of a word that change it’s meaning. Examples of common prefixes include: inter, intra, anti, milli, hyper etc. Most common prefixes are not hyphenated (check with a dictionary, or a technical writer).
Prefixes that are hyphenated include chemical terms with an italicized prefix: cis-dimethylethylene, or ß-lactose.
Use a hyphen when the second part of a word starts with the same vowel that the first part of the word ends with; For example, pre-eminent, re-educate, co-opt, semi-invalid, or if the word would be difficult to read without a hyphen; For example, co-author, de-icing.
