Your doctor will check your platelet count every week and change your dose of PROMACTA as needed until he/she decides that your dose of PROMACTA can stay the same. Once your doctor decides your dose can stay the same, you will need to have your platelet count checked once a month.
After stopping PROMACTA, your platelet count needs to be monitored weekly for at least 4 weeks to check if your platelet count drops too low.
Before starting PROMACTA, your liver function will be checked through blood tests. During dose adjustments, it will be tested every 2 weeks, transitioning to monthly tests once your dose can stay the same. In some cases, treatment with PROMACTA may need to be stopped due to changes in your liver function tests.
