Before you start taking CAMZYOS, your healthcare team will need to work out your starting dose. They will use a type of test called a CYP2C19 test to do this. It is important to speak to your healthcare team if you have any questions about CYP2C19 testing or CAMZYOS.
The CYP2C19 test is a pharmacogenetic test that looks at specific genes to see how fast one of your enzymes (CYP2C19) breaks down (metabolises) CAMZYOS and other medicines.
For the CYP2C19 test, your healthcare team will take a sample of your blood to send to a testing facility
The CYP2C19 test is different from genetic tests, which look at many different genes to see what is causing a disease.
The CYP2C19 test allows your doctor to see how active your CYP2C19 enzyme is. This activity is known as your ‘metaboliser status’, which can range from ‘slow metaboliser’ to ‘ultra-rapid metaboliser’ (see the diagram below). These results will help your doctor decide on the most appropriate CAMZYOS dose for you.
Slow metaboliser
This means that you break down certain medicines slowly. This may affect the dose of CAMZYOS you are given and what other medicines you can take at the same time.
Intermediate, normal, rapid, or ultra-rapid metaboliser
This means that you break down certain medicines quickly or at a normal pace. Your doctor may be able to increase your dose of CAMZYOS depending on how well you are doing on your current dose.
Your doctor will explain your results and what this means for your CAMZYOS treatment
