Porter Novelli

Montville, NJ, June 21, 2001 -- Berlex Laboratories, Inc., a U.S. affiliate of Schering AG, Germany (NYSE:SHR), announced today that YASMIN (R)(drospirenone and ethinyl estradiol), a new, low-dose, monophasic oral contraceptive containing the novel progestin drospirenone is now available to U.S. women in pharmacies nationwide.

"Because YASMIN is the first oral contraceptive in over 40 years to contain a new class of progestin, we believe there is significant market potential for this product," said Reinhard Franzen, Vice President and General Manager, Female Healthcare, Berlex Laboratories, Inc. "More than 18 million women in the U.S. currently use oral contraceptives, but nearly half of them discontinue use or switch brands. The major reason for such a high dissatisfaction rate is side effects. Yasmin offers these women a needed, new option in oral contraceptives."

The uptake of YASMIN by wholesale and retail pharmacy customers has been tremendous. "Many of our trade customers are utilizing specialized programs to get Yasmin to the pharmacy as fast as possible. These programs are typically reserved for products with $100 million market potentials. We are very optimistic that this response is indicative of potential sales growth for the product this year," added Franzen.

"Many of my patients have been dissatisfied with currently available birth control pills and a majority discontinue use due to side effects," said Michael Thomas, MD, Director of the Center for Reproductive Health, University of Cincinnati College of Medicine. "The unique mechanism of action in YASMIN places it in a class of its own, and I am pleased to offer my patients this new and exciting contraceptive option." Dr. Thomas added that YASMIN is ideal for patients who desire an oral contraceptive that is well tolerated. In clinical studies, only six percent of women discontinued use due to side effects.

The launch of YASMIN continues in the tradition of Schering AG, Germany, the Berlex parent company, which introduced oral contraceptives in the European market 40 years ago. YASMIN has been available in several European countries, including Germany, since November of 2000. Over 500,000 women in Europe are currently using YASMIN.

Large-scale clinical trials in the U.S. and Europe involving 2,629 women and over 33,160 cycles of use established the contraceptive effectiveness, safety and menstrual cycle control of YASMIN. Trials found that YASMIN offers excellent cycle control with a low rate of spotting and breakthrough bleeding. YASMIN proved more than 99 percent effective in preventing pregnancy.

YASMIN contains 3 mg of the progestin drospirenone that influences the regulation of water levels and electrolyte balance in the body. This activity may increase potassium levels in some patients. Therefore, women with kidney, liver or adrenal disease should not take YASMIN, because this activity could cause serious heart and health problems. Patients taking drugs that could increase potassium should consult their health care professional before taking YASMIN.

Drugs that may increase serum potassium when used on a daily long-term basis to treat chronic conditions or diseases include ACE inhibitors, angiotensin-II receptor antagonists, potassium-sparing diuretics, heparin, aldosterone antagonists and NSAIDs (i.e., daily use for arthritis).
