Bar Coding Chemicals
Bar coding of chemicals is another important step in ensuring quality compounding. Before bar coding was implemented, a compounder would pull all of the chemicals required to prepare a compound and a pharmacist would double check to make sure the correct chemicals had been pulled. The only problem with this system is there was no way to ensure the correct chemical was weighed at the proper amount. With bar coding technology, the pharmacist checks the chemical when it arrives at the pharmacy and assigns it a bar code that corresponds to the chemical name, lot number, expiration date and purity. When compounding, the compounder then scans the bar code and the computer will inform the compounder if the correct chemical is being used.
