Some medical treatment medications and prescription medications may contain prescription code numbers that have a different meaning for different countries.
The codes can help patients understand the dosage and how to take the medicine.
For example, a code of “12” could mean a 12-mg pill, whereas a code “21” means a 21-mg tablet.
If the drug is in a generic form, a generic code may not mean a generic version of the drug.
If a prescription is for an older drug, it may also contain a generic or brand code.
If you have questions about how to identify the correct medication codes, call your pharmacist.
