Jantoven is a blood thinner used to treat blood clots and prevent the development of new clots in your body.
How does this medication work?
Jantoven blocks the formation of substances in your body that help form blood clots, thereby lowering the chance of blood clots developing.
What are the beneficial effects of this medication and when should I begin to have results?
What: By lowering the chance of blood clots forming in your body, Jantoven reduces your risk of having a stroke, heart attack, or other serious conditions.
When: Everyone responds differently to treatment, so try to be patient and follow your healthcare provider's directions. It is important that you take Jantoven exactly as your healthcare provider has prescribed.
How do I know it is working?
Your healthcare provider will order a blood test to check how well your medication is working. This blood test is called an INR test. The INR test checks to see how fast your blood clots. Your healthcare provider will decide what INR numbers are best for you. Your dose of Jantoven will be adjusted to keep your INR in the target range determined by your healthcare provider.
Eat a normal, balanced diet while you are taking Jantoven, as this will also affect the results of your INR test.
