Here are some of the most common pharmacy technician mistakes that may occur when working as a pharmacy technician.

  • Dispensing of wrong medication.
  • Mixing up abbreviations and drug names.
  • Incorrect/similar drugs (Look-alike or Sound-alike drugs).
  • Misplaced decimals or zeros.
  • Delivering wrong prescription orders to patients.
  • I.V. mixing errors.
  • Dispensing wrong dosage or medication due to unclear prescription.
  • The wrong dosage of high-alert medications.
  • Failed accurate instruction by the patient.

Let’s now discuss these pharmacy technician mistakes in detail. 


One of the most common pharmacy technician mistakes is dispensing the wrong medication. This type of pharmacy technician mistake occurs when the doctor’s prescription is filled with the wrong medications. Pharmacy technicians dispense the wrong medications when they fail to read the prescription carefully.


The second most common pharmacy technician mistake is confusing or mixing up abbreviations and drug names mentioned on the patient’s prescription. Using abbreviations most likely leads to confusion when filling the patient’s prescription. This will mostly increase the risk of errors when handling those drugs.

For example, for ‘cubic centimeters’ the abbreviation is ‘cc’ which can be mistaken for ‘U’ for ‘units’.


One of the other common mistakes a pharmacy technician can possibly make is confusing look-alike or sound-alike drugs and drug names. When a new drug is introduced, you may not be familiar with the new terminology or drug name. In such situations, there are high chances of choosing similar look-alike or sound-alike drugs.


As a pharmacy technician, you will be required to work in a fast-paced environment and also multitask at the same time. So, most of the time, the pharmacy technician tends to read and fill prescriptions in a hurry, which may cause misplacing a decimal point, a zero, or a unit.

A misplaced decimal point, a unit, or a zero leads to dispensing the medicine in a much higher or lower dose than was prescribed. This often leads to life-threatening consequences risking the patient’s safety.


One of the most common pharmacy technician mistakes is delivering the wrong prescription order to the wrong patient. This often tends to happen as pharmacy technicians are expected to complete their tasks within a short span of time and also handle multiple patients or tasks at the same time.

This is also a mistake that may put the patient’s safety at risk if the patient ends up consuming the wrong medication.


Generally, I.V. Mixing errors occur when a pharmacy technician draws up a drug and injects it into a larger quantity, injects the wrong quantity and pulls back the plunger to the correct quantity, or injects the right quantity but pulls back the plunger to the wrong quantity. Any of these mistakes end up being an I.V. mixing error.


This pharmacy technician mistake occurs when the drug and dosage are mismatched. Often, the handwritten prescriptions by doctors may have poor legibility that leading to dispensing the wrong dosage of medication.


When a pharmacy technician takes the wrong dosage of high-alert medications, it puts the patient’s life at risk. Some high-alert medications are insulin, blood thinners, chemotherapy drugs, IV nutrition, injectable electrolytes, opioids, methotrexate, sedative agents, oral hypoglycemic, and opium tincture. The above-mentioned medications may cause serious harm to the patients when taken in the wrong dosage. 


As a pharmacy technician, it is your responsibility to give accurate and clear instructions to the patient when delivering the prescription order. Certain medications may have specific instructions to be followed that the patient who consumes them should be aware of.

Specific instructions, such as to refrigerate certain medications, some to be consumed with food, and for certain medications to be consumed hours after food. Not giving clear and accurate instructions may result in ineffective medication or unwanted side effects.

How to Avoid Pharmacy Technician Mistakes

Let’s now discuss some of the ways to avoid committing pharmacy technician mistakes.

  • Read the prescription correctly and patiently before you start preparing the prescription order. This may help avoid dispensing errors.
  • Communicate with the patient clearly by giving them all the required instructions while delivering the prescription order.
  • Familiarize yourself with new terminologies and drug names regularly.
  • Label drug names and properly maintain a dedicated space for each drug to avoid confusion between the look-alike and sound-alike drugs.
  • Double-check before dispensing the medication and before handing over the prescription to the patient.
  • In case of an unclear prescription, seek the help of a coworker or the pharmacist before proceeding to dispense the medication.
  • Read and double-check the units, decimals, and zeros before entering the data.
