- a pharmacist mixes a medication incorrectly either by using the wrong ingredients or incorrect drug solutions;
- a pharmacy incorrectly mixes a prescription and makes it stronger than intended;
- measuring units are substituted incorrectly by a pharmacist;
- pharmacy uses inadequate monitoring and measuring techniques.

The goal of every pharmacy should be to follow strict quality control systems in order to prevent medication errors. Unfortunately, the reality is that mistakes happen in these systems and pharmacies administering medication are not shielded in any way by errors.Computers miss 72% of dangerous drug-drug interactions!
