Not feeling the love, ladies? The FDA’s just approved Addyi, aka flibanserin or “female viagra,” to help treat women’s lack of sexual desire. Having rejected it twice before, federal authorities did an about-face yesterday following a June advisory panel vote in favor of the pill produced by Sprout Pharmaceuticals. The drug targets neurotransmitters believed to impact arousal. Some say the benefits aren’t worth the side effects, including nausea and sleepiness, and complain that the medicine — due to hit shelves on Oct. 17 — must be taken every day.
