The story
Founded by Günther Friedländer on Feb 13, 1944, in Israel.1
Salomon, Levin, and Elstein
Teva's earliest predecessor was SLE, Ltd., a wholesale drug business founded in 1901 in Ottoman Empire's Mutasarrifate of Jerusalem. SLE Ltd. took its name from the initials of its three cofounders: Chaim Salomon, Moshe Levin and Yitschak Elstein, and used camels to make deliveries. During the 1930s, new immigrants from Europe founded several pharmaceutical companies including Teva and Zori. In the 1930s, Salomon, Levin, and Elstein Ltd. also founded Assia, a pharmaceutical company.
1935–1949
Teva Pharmaceutical Industries took its present form through the efforts of Günther Friedländer and his aunt Else Kober on May 1, 1935. The original registration was under the name Teva Middle East Pharmaceutical & Chemical Works Co. Ltd. in Jerusalem, then part of Mandatory Palestine. Friedländer was a German pharmacist, botanist and pharmacognosist, who immigrated to Mandatory Palestine in 1934.
The company was built with an investment of £4,900, which came from the family's own capital and partly from loans from other German immigrants. Capital shortage led to the joining of the banker Alfred Feuchtwanger as a partner in Teva, who received 33% of the shares in return for his investment.
Friedländer's business philosophy opined that the pharmaceutical industry has a reliable basis in difficult economic times, since "A Jewish mother will always buy medicine for her children". In the Second World War, the company provided medicine to the allied forces and in particular to the British army present in the Middle East. After the war, Sir Alan Gordon Cunningham, the last of the High Commissioners for Palestine and Transjordan, visited Teva on behalf of the Secretary of State for the Colonies. His visit promoted Teva's reputation in the pharmaceutical market and created a momentum for Teva's development.
During Mandatory Palestine, Teva exported its medical products to Arab countries. In 1941, Friedländer presented Teva products in an exhibition held in Cairo, Egypt. The exhibition was sponsored by the General Agent and Sole Distribution of medicine in Egypt and Sudan, Syria and Lebanon. Later on, Teva exported its products to the US, Soviet Union (USSR), health institutes in Denmark, Czechoslovakia, Persia and Burma.
1950–1999
In 1951, Feuchtwanger initiated an initial public offering to raise capital through the newly founded Tel-Aviv Stock Exchange and Teva became a public company. In 1954, Teva received a Certificate Excellence in Training award from the Israeli President, Yitzhak Ben Zvi. In 1964, Teva partnered with Sintex, a company from Mexico, and Schering Plough.
In 1964, Assia and Zori merged and in 1968 acquired a controlling stake in Teva. In 1976, the three companies merged into the modern-day Teva Pharmaceutical Industries Ltd. In 1980, Teva acquired Ikapharm, then Israel's second largest drug manufacturer.
In 1980, Teva acquired Plantex.

In May 2011, Teva bought Cephalon for US$6.8 billion.

In April, Teva offered to acquire Mylan for $40 billion, only a fortnight after Mylan offered to buy Perrigo for $29 billion.

Following considerable lobbying by the Israeli Government, from whom Teva received considerable tax breaks, and from Israel's labor federation, the Histadrut, Teva agreed to delay some of the layoffs in Israel.

After completing the $39 billion acquisition of Actavis Generics, Teva announced another, smaller, deal with Allergan, agreeing to acquire its generic distribution business Anda for $500 million.
Divestments
On October 21, 2011, Par Pharmaceutical has sealed the deal to three products from Teva Pharmaceutical Industries, which the Israeli firm was required by the US Federal Trade Commission to divest before it could acquire US biotech Cephalon for $6.8 billion.

2020s
In August 2025, Teva released the first generic version of a GLP-1 semaglutide product, named Saxenda. Saxenda is not a generic version of semaglutide (Ozempic) which is within patent protection. Saxenda is a generic of an older medication, liraglutide, that has been found to cause thyroid cancer in rats but with no evidence this risk extends to humans.
