What Is Merck?

Merck is an American pharmaceutical company and one of the largest in the world.

Outside the U.S. and Canada, Merck is known as Merck Sharp & Dohme.

Merck History

Merck & Co. began in 1668 in Darmstadt, Germany.

Friedrich Jacob Merck opened the pharmaceutical company under the name Angel Pharmacy (Engel-Apotheke). He sold morphine, cocaine and codeine.

The company became a manufacturer in 1827. Heinrich Emanuel Merck changed the course of the business under its new name E. Merck.

U.S. Beginnings

A U.S. sales office opened in 1887. And in 1891, the company’s U.S. branch Merck & Co. opened. George Merck, Heinrich’s grandson, headed its operation.

The U.S. branch of Merck grew. The company established a manufacturing facility in Rahway, New Jersey in 1902.

Merck & Co. corporate office
Merck & Co. has offices in 278 locations.

In 1917, after World War I, the government confiscated Merck & Co. and set it up as an independent company.

The original German Merck is now known as Merck KGaA. It has no affiliation with Merck & Co.

Major Pharmaceutical Successes

Merck & Co. sold the first commercially used smallpox vaccine in the U.S. in 1898.

The next year, it published a guide for physicians and pharmacists known as The Merck Manual.

The manual is available in 17 languages today. It’s one of the most used texts in the world.

Growing Empire

Merck agreed to merge with Philadelphia pharmacy Sharp & Dohme in 1953.

Together, the companies became the largest U.S. manufacturer of prescription drugs at the time.

Merck has more than 50 pharmaceutical products to its name.

The company specializes in products for cardiovascular, respiratory and infectious diseases. It also focuses on cancer, nervous-system disorders, immunology and women’s health.

Clinical studies link some of Merck’s pharmaceutical products to dangerous side effects. The U.S. Food and Drug Administration strengthened warnings for some of the drugs.

Merck Lawsuits and Settlements

Patients injured by Merck’s drugs have filed thousands of lawsuits against the Big Pharma company. The drug maker has paid out billions of dollars in damages to patients and their families as a result.


Fosamax Pills

Merck paid millions in settlements and jury verdicts to thousands of people who say Fosamax caused their injuries. Multidistrict litigation (MDL) in New York over Dead Jaw Syndrome has mostly resolved. A second MDL in New Jersey for bone fractures involved more than 560 lawsuits as of May 2018. More Fosamax lawsuits are pending in multicounty litigation (MCL) and state courts.


Januvia pills

Studies link Januvia to pancreatitis, pancreatic cancer and severe joint pain. According to lawsuits, some former Januvia users died after using the drug. A judge dismissed Januvia lawsuits in 2015. But as of 2018, an appeals court reinstated hundreds of pancreatic cancer lawsuits.


NuvaRing silver small

Organon, a subsidiary of Merck, manufactures NuvaRing, a birth control ring associated with life-threatening blood clots. Because of the possible side effects, the FDA released a drug safety communication in October 2011. People filed more than a thousand federal NuvaRing lawsuits. The company settled almost all of them for $100 million in 2014.


Propecia pills

Merck changed Propecia’s label in 2011 to warn of the possibility of cancer and sexual side effects. It warned side effects may continue even after stopping treatment. As of May 2018, about 900 Propecia lawsuits remained pending in federal court in New York.

Merck Recalls

Vioxx Pills

Vioxx is one of Merck’s most well-known drug recalls.

Vioxx is a COX-2 inhibitor (pain reliever). It was linked to an increased risk of cardiovascular problems like heart attack and stroke.

The painkiller was on the market for five years before Merck pulled the plug. The FDA approved Vioxx in 1999. An estimated 25 million Americans used the drug.

Merck denied reports of dangerous cardiac side effects for years. But in September 2004, it pulled the drug from the market. It based its decision on findings from a clinical trial called APPROVe.

Vioxx was blamed for more than 3,400 deaths.

Merck paid nearly $7 billion to settle tens of thousands of Vioxx lawsuits and to cover civil and criminal fines.

Did You Know?
Merck's Vioxx settlement ended personal injury lawsuits brought by 47,000 people and about 265 potential class-action cases.
