Washington/New York

The first drug to treat low sexual desire in women won approval from U.S. health regulators on Tuesday, but with a warning about potentially dangerous low blood pressure and fainting side effects, especially when taken with alcohol.

The U.S. Food and Drug Administration said the pink pill, to be sold under the brand name Addyi and made by privately held Sprout Pharmaceuticals, will only be available through certified and specially trained health care professionals and pharmacies due to its safety issues.
