Answer

PT should be measured on a regular basis; the goal is an INR of 2-3.

The length of treatment depends on the presence of risk factors. If no underlying risk factors are present, therapy can be stopped within 1-2 months. If risk factors are present, especially anticardiolipin antibodies, therapy should continue for at least 4-6 months.
