Providing comprehensive prescription medication information you can trust, MedLibrary.org formats and delivers product label and package insert information directly from the FDA’s repository of Structured Product Labels.

About Our Medication Information

Our medication database comes directly from the FDA’s central repository of drug labels and package inserts under the Structured Product Labeling standard. This HL7 data standard has been adopted by the FDA as its primary mechanism for the exchange of formatted health product information.

Our health information, sourced directly from the FDA repository, is transformed from machine-portable XML into a human readable web page, rendered with improved formatting and paginated for readability — but it is not otherwise modified with regard to medical content.

Every medication information entry includes an effective/last revision date, together with full details of the company providing that information to the FDA.


The quality of information provided on this site depends directly on the quality of what was originally provided in XML form to the FDA by the manufacturer. Unfortunately, many submissions by drug manufacturers suffer from incompleteness, incorrect formatting, formally invalid XML, or all three, and this may result in anomalies in the final human readable web page which range from poor visual presentation (e.g., inappropriate line breaks) to something approaching gibberish (e.g., incorrectly repeated or out of order sentences). While the industry continues to work to improve the quality of information supplied to the FDA, users of SPL data should be vigilant for these problems and should take appropriate steps to corroborate the information. This site operates several automated filters in an attempt to exclude entirely the most badly broken XML records and the gibberish which can result, but unfortunately we are not always successful; if you should encounter faulty records on this site, please direct any questions or requests for corrections to the drug manufacturer rather than to us, as it is not possible for us to correct problems in the manufacturers’ FDA submissions ourselves.

In addition, as per the FDA guidelines on use and interpretation of SPL resources, please take note of the following standard disclaimer:

The drug labels and other drug-specific information on this Web site represent the most recent drug listing information companies have submitted to the Food and Drug Administration (FDA). (See 21 CFR part 207.) The drug labeling and other information has been reformatted to make it easier to read but its content has neither been altered nor verified by FDA. The drug labeling on this Web site may not be the labeling on currently distributed products or identical to the labeling that is approved. Most OTC drugs are not reviewed and approved by FDA, however they may be marketed if they comply with applicable regulations and policies described in monographs. Drugs marked “OTC monograph final” or “OTC monograph not final” are not checked for conformance to the monograph. Drugs marked “unapproved medical gas”, “unapproved homeopathic” or “unapproved drug other” on this Web site have not been evaluated by FDA for safety and efficacy and their labeling has not been approved. In addition, FDA is not aware of scientific evidence to support homeopathy as effective.

Regarding homeopathy, please note that this site does not knowingly carry any FDA-supplied information on homeopathic products. However, occasionally such products have been incorrectly categorized in the source files provided to us by the FDA. Normally, the FDA identifies such errors and removes or recategorizes these entries at a later date, in which case these changes will then be reflected in the information we provide.

Who Backs Us and Why We Exist

This site is provided by Mulhauser Consulting, Ltd., a consulting firm, and the editorial process is overseen by Dr. Greg Mulhauser, its Managing Director. Dr Mulhauser is not a physician, and our medical information itself has not been edited or altered in any way except as described above. (The ‘Dr’ indicates a PhD, not an MD.) The site receives no funding or other support except for Dr Mulhauser’s time and advertisements placed by third parties — for example, Google AdSense, as described below.

The site came into existence because of Dr Mulhauser’s recognition, in the course of his work as a professional counselor and consultant, that clients frequently value clear and comprehensible information, geared for consumers, on medications which have been prescribed for them — not just in the context of mental health, but more generally. This site exists to offer access to one of the medical community’s leading sources of that information in an easy-to-use form.

Our Advertising Policy

At this time, we employ context-driven advertisement banners supplied by external agencies. These advertisements are supplied directly by companies such as Google, based upon proprietary indexing technology and algorithms which aim to match advertisements displayed with the content of a page. Because we do not know in advance what advertisements Google may select for display in connection with any specific content, we cannot be influenced by the interests of any particular advertiser. In addition, we cannot offer any comment (endorsement or otherwise) about any specific advertisement supplied via Google or any other third party.

All advertising is clearly separated from medication information. In the case of ads by Google, text ads include the phrase “Ads by Google”, while image ads include the distinctive Google encircled ‘i’, which when moused over reveals the text “Ads by Google”. Medication information supplied by this site never carries a label such as “Ads by Google”.

You can help support this site by visiting the sites of any sponsors displayed by our third-party advertising systems which you may find relevant.

Our Editorial Policy

As indicated above, all medical information is represented here exactly as received from the database supplier, without modification.
