One of heparin's primary manufacturers, Baxter International, had begun monitoring reports of adverse reactions in December, and stopped producing multiple-dose heparin vials on Feb. 11 after four deaths were reported. To date, over 800 cases of adverse effects have been reported, including 21 deaths. A large-scale recall of the product was not ordered, as the FDA feared problems associated with a sudden shortage. Baxter supplies approximately half of the heparin used in the U.S.

The nose is lined with blood vessels that warm and increase the level of moisture in the air that we breathe in. These blood vessels lie close to the surface which makes them easily susceptible to being injured and broken. Inhalation of dry air in hot indoor / outdoor climate can make the moist lining (mucous membrane) inside your nose dry and thinner. As a result, the blood vessels in the lining become more prone to bleeding. Picking nose, injury or blowing the nose too hard to clear the passages during cold, are common reasons of bleeding nose in kids and adults. All these conditions usually cause sporadic instances of nosebleeds.
