According to a study done by Seattle-based Fred Hutchinson Cancer Research Center, long-term use of painkiller acetaminophen puts users at risk of developing blood cancers. The survey based on a six-year study of 65,000 people above 50 years found that several of chronic acetaminophen users developed blood cancer after taking the drug over a long period of time. Those who took acetaminophen four times or more in a week for four years became twice prone to developing blood malignancies than those who did not use the Tylenol drug.
Acetaminophen, popularly known as Tylenol, is the most commonly used pain killer and anti-inflammatory over-the-counter and prescription drug. It is a component of more than 100 medicines. An overdose of the drug is linked to several health concerns, including liver failure. In recent years, the FDA has issued warnings to drug manufacturers in the United States to use the lowest possible doses of acetaminophen in their products. The federal regulator is concerned over the incidence of its use for variety of medications.
