I used to work at a pharmacy, and the meds were pulled by one person, filled by another, then checked by a pharmacist before being sent out. Even with all those people checking, we still got things wrong once in a while. I'm not saying it should happen, ever, but when you've got hundreds of orders that you're pressured to have out quickly, mistakes can and do happen.

Cedars-Sinai Medical Center Tuesday revealed just went wrong on Nov. 18 when three patients, including Dennis Quaid's infant twins, were given a near-fatal overdose of the anti-clotting drug Heparin.
"The medical center’s investigation found that preventable errors made by pharmacy and nursing staff caused the wrong concentration of heparin to be used," the hospital said in a statement.
"A pharmacy technician failed to follow hospital policy of having another pharmacy technician verify the medication and concentration prior to removing it from main pharmacy inventory. As a result, the technician mistakenly retrieved a higher concentration of heparin (10,000 units per milliliter) instead of the lower-concentration heparin (10 units per milliliter) used for flushing IV catheters.
"The higher concentration heparin was delivered to the satellite pharmacy that serves the pediatrics unit. A second pharmacy technician, working in the satellite pharmacy, did not verify the concentration of the delivery from the main pharmacy, as required by hospital policy."
The hospital's press release comes on the same day that Quaid filed a lawsuit against Chicago-based Baxter Healthcare Corp., maker of Heparin.
Quaid, who has not sued Cedars-Sinai, is suing the drug company because he wants to prevent it from happening to any other children. Quaid's attorney said three children died in Indiana from a similar mix-up with the drug.
Without naming Quaid's babies, Zoe Grace and Thomas Boone (who are now back home), the hospital said that "two patients were given protamine sulfate, a drug that reverses the effects of heparin and helps restore blood clotting function to normal. Additional medical tests and clinical evaluation conducted on the two patients found no adverse effects from the heparin or from the temporary abnormal clotting function."
“Although this was a rare event, and attributable to human error, it is also an important opportunity for the entire institution to explore any and all ways we can further improve medication safety,” said Michael L. Langberg, M.D., chief medical officer at Cedars-Sinai Medical Center.
“On behalf of the medical center, I extend my deepest apologies to the families who were affected by this situation, and we will continue to work with them on any concerns or questions they may have. This was a preventable error, involving a failure to follow our standard policies and procedures, and there is no excuse for that to occur at Cedars-Sinai,” Langberg said.
The hospital said that all employees involved in the accidental overdoses have been "relieved of duty pending investigation, and appropriate disciplinary actions are being taken."
