Monitoring Your Jantoven Dosage
Monitoring during treatment with
Jantoven is essential. Even people who have been on a steady dose of Jantoven for years require frequent monitoring. This is done using a blood test known as a prothrombin time (also known as a "protime" PT) or international normalized ratio (INR). The INR is actually just a standardization of the PT test that accounts for laboratory variations. This monitoring will be done daily when you first start Jantoven, until you reach a stable and appropriate INR. Thereafter, INR monitoring is done periodically, usually every one to four weeks (and more often when necessary).
Although your physician may choose to monitor your Jantoven dosing, he or she will often suggest having a "Jantoven clinic" manage your monitoring and dosage. These are clinics run by specially trained pharmacists (or sometimes nurse practitioners) who specialize in monitoring and dosing with this drug.
