Why Sylvant
Starting SYLVANT
What you need to know about receiving SYLVANT
For the first 12 months of SYLVANT therapy, your doctor will order blood tests before each infusion to make sure your body is ready for treatment. After that, you will need blood work every 3 dosing cycles.
Before each visit, it may be helpful to write down how you have been feeling and any thoughts or questions you may have.
Where you go for your SYLVANT infusions is up to you and your doctor. You may decide to go to a specialized academic center, a local community hospital, or an infusion center. For some patients, home infusion may be an option.*
Select a location that is most convenient to you.
- *Insurance coverage of home infusion treatments varies by patients’ provider and plan. SYLVANT treatment must be initiated in an office or clinic setting before transitioning to home infusion.
The SYLVANT infusion: 1 hour every 3 weeks
While the actual infusion only takes 1 hour, you should expect to be at the infusion center longer for other things such as blood work, preparation of the infusion, and meetings with your doctors.
When I received my idiopathic multicentric Castleman disease (iMCD) diagnosis, I was relieved because I knew I was going to receive the proper treatment…and that made me hopeful for the future.
Infusion day
When it comes to your SYLVANT infusion days, it’s important to be good to yourself. Give yourself plenty of time to get to the appointment and have enough time to talk with your doctor, infusion nurse, or healthcare practitioner.
Here are some tips that may help you plan for infusion day:
Wear loose-fitting clothing and layers in case you get too warm or too cold.
Get a good night’s sleep before the day of your SYLVANT infusion.
Have a good breakfast—it’s important to keep your strength up.
Plan to take it easy for the rest of the day after an infusion.
