Let's take a minute to talk about your medication. 

This is Vonvendi. It helps manage von Willebrand disease. Vonvendi contains a blood clotting factor called 'von Willebrand factor', or 'vWF' for short. It raises low levels of vWF to healthy levels. This can help prevent and control bleeding episodes. 

You should use it exactly as your doctor tells you to. Also, make sure you understand the dose instructions.

This medicine is given into a vein. This is known as an 'intravenous' or 'IV' infusion. You may receive your doses in a clinic, at the doctor's office, or at home. Your doctor may check your blood pressure during the dose. 

Before using this medicine at home, you must receive training from your healthcare provider. You must also read the "Instructions for Use". 

Some side effects can include mild itching, hot flashes, muscle twitches, and an unusual taste in the mouth. You should call your doctor if these effects or others do not go away, or if they get worse instead of better. Also, you should ask about possible infections or reactions at the injection site, and when to report symptoms.  

As with any medicine, more serious side effects can occur. With Vonvendi, this includes an allergic reaction. You should read the 'Patient Information Sheet' for more information. Also, call your doctor right away if you get a rash or hives, itching, problems with breathing, or a tight feeling in the throat or chest. Also, call right away if you have nausea, lightheadedness, dizziness or fainting. 

Your body may form inhibitors to this medicine. Inhibitors can prevent Vonvendi from working. So, call your doctor right away if your bleeding does not stop after taking it. 

For best results with Vonvendi, ask about patient support services that are available.
