As of 2015, several websites have drug interaction checkers for the public to use, including Drugs.com, WebMD.com, RxList.com, Healthline.com and AARP.org, according to each of these resources. Drug interaction checkers help patients determine if medications, supplements and foods may interfere with someone's course of treatment as prescribed by a doctor.
For example, patients may type in a generic or brand-name drug into the search box on Drugs.com. As the drug name appears in a list below the search box, people may click on a selection to view that particular drug, explains Drugs.com. Consumers may then continue to add as many drugs as needed to the list. Patients view all possible interactions by clicking the button labeled Check for Interactions. Users may create a free account with this website to save lists and add to them later.
Another choice involves typing in at least the first three letters of a drug or herbal supplement into the search box, according to WebMD. A list appears below the box that allows consumers to scroll through a list of possible drug names. After users add a second drug to the list, the website shows if any interactions occur at the bottom of the list. Patients may sign in to save lists, receive alerts and save items to a mobile app to view drug interactions later. This service also lets consumers add drugs at a later date.
