ETHEX Corporation announced that it voluntarily recalled generic /non-branded products that it markets. These lots have been recalled as a precaution, due to the possibility that they may contain oversized tablets. Oversized tablets may contain more than the intended levels of the active drug ingredient, which could result in patients receiving as much as about twice the expected dosage of these drugs. Overdoses of Propafenone HCl, Isosorbide Mononitrate, Morphine sulfate and Dextroamphetamine Sulfate can have serious or life-threatening consequences. In the case of Propafenone HCl, these consequences can include arrhythmias (irregular heartbeat) and low blood pressure. In the case of Isosorbide Mononitrate, these consequences can include fainting and low blood pressure. In the case of Morphine Sulfate, these consequences can include respiratory depression (difficulty or lack of breathing) and low blood pressure. In the case of Dextroamphetamine Sulfate, these consequences can include rapid heart rate and high blood pressure.
