Medical Science LiaisonJob Description, Salary, Career Path, and Trends

A Medical Science Liaison (MSL) is a healthcare professional who acts as an advocate and educator for a pharmaceutical company. They work with healthcare professionals, such as doctors and pharmacists, to create a better understanding of the products that the pharmaceutical company produces. MSLs also provide support to patients and their families when it comes to using medications.

In addition to being familiar with the diseases and conditions that a company’s drugs treat, MSLs must have extensive knowledge of the products themselves. They must be able to understand how medications work, what side effects might occur, how they should be used (including dosage), and know when they should not be used. MSLs need to have a firm grasp on the safety requirements and legal issues surrounding medication use.

Typical work environment

Most MSLs work in healthcare settings, such as hospitals or doctor’s offices. They may also travel to educational events that doctors attend in order to improve their understanding of a company’s products. The time that an MSL spends at these events will vary depending on the company and the product.

Medical Science Liaisons typically spend their days interacting with various internal departments, including sales representatives, marketing teams, and reimbursement specialists. They may also deal with external third parties, such as healthcare professionals, researchers, patients, and patient advocacy groups. In this role, it is essential to have a comprehensive understanding of the drug development process and be able to communicate complex scientific information in a way that is easy to understand.

Typical hours

In this profession, the number of hours worked varies from employer to employer. However, those who find employment at research institutions typically work a standard 40-hour week. MSLs who work for pharmaceutical companies may be required to travel, which can add on additional hours.

Available certifications

There are no official certifications available for the Medical Science Liaison position, however, having a degree or Ph.D. that directly relates to medicine and/or pharmaceuticals is often preferred.

Medical Science Liaisons need to keep up with the rapidly changing landscape of medicine and science, which requires a great deal of self-education. Many MSLs are required to attend training and meetings throughout the year in order to stay up-to-date on the company’s products.

Career path

Medical Science Liaisons often start their career in related fields, such as medical writing or drug development. Those who have gained experience in the medical device or pharmaceutical industries typically have an easier time transitioning into this role. MSLs often have the opportunity to move up in their career and take on varying responsibilities, such as becoming a key opinion leader or management.

US, Bureau of Labor Statistics’ job outlook

SOC Code: 19-1042

2020 Employment133,900
Projected Employment in 2030156,600
Projected 2020-2030 Percentage Shift 17% Increase
Projected 2020-2030 Numeric Shift22,700 Increase

The employment of Medical Science Liaison is projected to grow 17 percent from 2020 to 2030; much faster than average for all occupations. Advances in technology will continue to improve health care services, allowing medical and health service managers to focus less on operational details and more on strategic decisions.

MSLs are also in a unique position to understand how patients and doctors use medications, which can help companies develop products that better meet the needs of patients. They can also provide valuable feedback to companies about how products are being used in the real world.

The job outlook for Medical Science Liaisons is positive. The increasing number of people with health insurance and the aging population will lead to more jobs in hospitals, nursing homes, and other healthcare facilities.

Companies are attracted to MSLs because they have extensive pharmaceutical knowledge and are influential with healthcare professionals. They can explain complex information about new or existing drugs in a way that makes sense to doctors and pharmacists, who often don’t have the time or the inclination to become as familiar with products as they should be.
