However, some adverse effects appear only after they are used in the general population.  Serious adverse effects regarding 13 drugs have been reported to the FDA between July and September 2010.  The FDA is currently keeping a careful watch to see if these drugs actually result in the reported side effects, and whether further regulatory changes like restricting their use may be needed.   These drugs are mentioned below:
