Jantoven Dosage

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.

General Information on Dosing With Jantoven

Considerations for people taking Jantoven include the following:
  • This medication comes in tablet form. It is usually taken by mouth once a day.
  • Although it does not matter what time of day you take this medication, be sure to take your dosage at the same time each day.
  • You can take Jantoven with food or on an empty stomach.
  • If necessary, the tablets can be broken in half. However, it is best to avoid this, since even tiny variations in the dose can cause problems.
  • For the medication to work properly, it must be taken as directed.
  • If you are unsure about anything related to your Jantoven dosage, please talk with your healthcare provider, nurse, or pharmacist.
