Sigma-Aldrich, an international chemical, life science and biotechnology company, offers a publicly accessible antibiotic selector tool on its website. The tool allows users to select from alphabetical groupings that lead to lists of antibiotics in ascending alphabetical order.
Wikipedia also has a page that lists antibiotics in ascending alphabetical order, grouped in charts by class. Once a user has identified a specific antibiotic, that person can research the drug on sites such as Drugs.com or WebMD. Drugs.com provides a drug index that allows users to enter a drug name and find information such as side effects, drug interactions, dosage, support group questions and answers, and user reviews. WebMD offers a Find a Drug search tool that conveys similar content, including uses, side effects, precautions, drug interactions and images. User reviews and overdose information are also available.
