A drug calendar and reminder system is provided which allows for a user to be reminded when and how to take regularly scheduled drugs. The drug calendar and reminder system allows a user to input one or more drugs including their dosage instructions and schedule, and creates interactive reminders to facilitate the regular taking of these drugs. The drug calendar and reminder system can be further configured to receive content from content providers, such as drug interaction services, drug databases, doctors, and pharmacies such that a user can readily access information from these providers as needed. The drug calendar and reminder system can also be configured to compile the user's drug information, and can be configured to allow content providers access to this information.
