In addition to taking Anagrelide itself, you also need to pay attention to following the scheduled follow-up checks, informing your doctor of all medications you are currently taking, and strictly following medical advice.

1. Before Treatment

All patients must undergo a cardiovascular evaluation, including an electrocardiogram (ECG); at the same time, evaluate underlying cardiopulmonary diseases and check liver function and electrolytes.

The reason this must be done beforehand is that the prescribing information clearly states—patients with known risk factors for QT interval prolongation should not use Anagrelide, including congenital long QT syndrome, a history of acquired QTc prolongation, current use of medications that may prolong QTc, and hypokalemia.

2. The First Week of Treatment

Platelet counts should be checked every 2 days. This is to prevent platelets from dropping too quickly or too low, which in turn brings a risk of bleeding.

After the first week and until the maintenance dose is reached: Platelet counts should be checked at least once a week. The pace of dose escalation is determined by these values.

3. After Reaching the Maintenance Dose

Platelet count monitoring should be changed to once a month, or as required by the doctor.

Throughout the entire course: Complete blood count, liver function, kidney function, and electrolytes; among them, liver function must be evaluated both before and during treatment.

Electrocardiogram (ECG) re-examination as needed: For patients with heart failure, bradyarrhythmias, or electrolyte abnormalities, the prescribing information requires considering regular ECG monitoring.

4. Moderate or Greater Hepatic Impairment

Risk-benefit evaluation is required before treatment; during medication use, close monitoring for QTc prolongation and other cardiovascular adverse reactions is necessary.

Why such a dense frequency: Platelet counts typically begin to respond within 7–14 days at the correct dosage, and a complete response takes 4–12 weeks. The follow-up schedule is designed precisely according to this time pattern; do not skip it.

5. Things You Should Tell Your Doctor

Before undergoing any surgery, tooth extraction, gastroscopy/colonoscopy biopsy, or other invasive procedures, proactively inform the surgeon, anesthesiologist, and procedural physician that you are taking Anagrelide—because it affects both platelet counts and bleeding risks; they will decide whether any adjustments are needed.

6. Mood and Sleep

Reported adverse reactions include depression, confusion, nervousness, somnolence, insomnia, and amnesia.

If significant low mood, lack of concentration, or sleep disturbances occur during treatment, do not simply attribute them to "feeling bad due to illness"—you should inform your doctor, as these fall under the category of adverse reactions listed in the prescribing information and require evaluation.

7. What Happens If You Take Too Much (Overdose)

When exceeding the recommended dose, Anagrelide has been shown to cause hypotension. Because the platelet-lowering effect is dose-dependent, thrombocytopenia is expected in the event of an overdose, which may consequently lead to bleeding.

Management principles: Discontinue the medication, monitor platelet counts, and observe for complications such as bleeding; once the platelet count returns to the normal range, resumption of treatment may be considered—this step is decided by the doctor.

If an accidental overdose occurs, please bring the medication box and seek medical attention immediately.
