Receiving your prescription
Once you’ve been prescribed AYVAKIT, your doctor sends your prescription to an eligible pharmacy or to YourBlueprint®. The pharmacy will verify your insurance coverage and work directly with your healthcare provider to obtain prior authorization if needed. Then, when coverage is approved, your pharmacy will contact you to communicate your out-of-pocket costs and arrange for delivery or pickup of your medication.
How do I take AYVAKIT?
One 25 mg tablet
Taken once a day or as directed
On an empty stomach, at least 1 hour before or at least 2 hours after a meal
The recommended dose of AYVAKIT is 25 mg orally once daily in adults with indolent systemic mastocytosis (ISM).
If you miss a dose of AYVAKIT, take it as soon as you remember, unless your next scheduled dose is due within 8 hours. Then, take the next dose at your regular time. If you vomit after taking a dose of AYVAKIT, do not take an extra dose. Take your next dose at your next scheduled time.
Talk to your doctor if you have questions about your treatment. Take AYVAKIT exactly as prescribed by your doctor. Do not stop taking AYVAKIT unless your doctor tells you to.
Before taking AYVAKIT, tell your doctor:
- All your medical conditions, including if you have a history of bulging or weakening of a blood vessel wall (aneurysm) or bleeding in your brain, history of stroke within the last year, have low platelet counts
- All the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Especially tell your healthcare provider if you take medicines that prevent blood clots.
- If you have or have had liver problems
- If you are pregnant or plan to become pregnant
- If you are breastfeeding or plan to breastfeed
How often will my doctor monitor my blood counts?
Your doctor will discuss with you when it is necessary to monitor your blood counts.
Monitoring how you are feeling
While taking AYVAKIT, it’s important to track your symptoms and any side effects you experience. Keep your scheduled follow-up visits with your doctor so they can monitor your condition while taking AYVAKIT.
How does AYVAKIT work?
About 95% of patients with ISM have a gene mutation called KIT D816V. This gene mutation can lead to the uncontrolled growth and buildup of mast cells, which can lead to symptoms of ISM. AYVAKIT works by selectively targeting the KIT D816V gene mutation to help slow the growth of mast cells.
You do not need to have the KIT D816V gene mutation to be prescribed AYVAKIT.
