PillPack wants to solve medication problems with its new online pharmacy service. The startup has launched its service in 31 states in the US to help patients manage their medications and avoid errors, according to VentureBeat.

The Massachusetts-based startup has raised $4 million in venture funding in July 2013 from Founder Collective and Atlas Venture. The company has opted to delay the announcement of this funding until its commercial launch today, the report detailed.

For a monthly fee of $20, the pharmacy service will sort, manage, and organize the mediations and vitamins of a patient who has signed up online. Each customer will be given a two-week roll of individually packed meds which are sorted according to time and date. PillPack will coordinate with a customer's doctor and insurance provider and will manage the refills. Clients are given a comprehensive billing charge every two weeks. The firm even has pharmacists available round the clock to answer queries, the report explained.

Atlas Venture partner Fred Destin said of the startup: "PillPack is a breath of fresh air for anyone who has spent endless hours counting pills, coordinating medications and navigating a complex system that causes frequent and often serious errors."
