KRYSTEXXA is a biologic treatment, which means it's made from a living source. Biologics are at the forefront of medical advances and can treat the causes of diseases rather than the symptoms. Some biologics are delivered directly into the bloodstream via an intravenous (IV) infusion that you can receive in a variety of settings.
Your doctor may be able to give you KRYSTEXXA right in his or her office.
As more IV treatments become available, so do more choices of standalone IV treatment centers.
Hospitals with outpatient IV treatment centers may be a convenient option.
Wherever you get KRYSTEXXA, a trained healthcare professional will administer your treatment and monitor you through the duration—usually about 2 hours—for signs of an infusion reaction or other side effects that they can treat on the spot. To help manage uncontrolled gout, it’s important to receive KRYSTEXXA every 2 weeks for 6 to 12 months* or for as long as your doctor recommends.
*Best results were seen after 6 to 12 months of treatment. Optimal treatment duration has not been established.

If your doctor decides that KRYSTEXXA is right for you, a Patient Access Liaison (PAL) can tell you more about each site of care, check your insurance coverage, and help you identify options for IV treatment centers near you.
Your doctor may prescribe KRYSTEXXA with a medication called methotrexate to reduce the symptoms of uncontrolled gout. You will also be given folic acid to help prevent some of the side effects of methotrexate. Your doctor will explain the dosing schedule.
At Month 6 of a clinical study
71% of people on KRYSTEXXA
along with methotrexate kept their
uric acid levels below 6 mg/dL
39% of people on KRYSTEXXA alone
kept their uric acid
levels below 6 mg/dL
Methotrexate can help KRYSTEXXA work better than it did before.
Improvement is typically seen in 6 to 12 months.† If you and your doctor decide methotrexate is not right for you, KRYSTEXXA is effective when taken alone.
†Optimal treatment duration has not been established.

What should I tell my doctor before receiving treatment with KRYSTEXXA?
Before you receive KRYSTEXXA, tell your doctor about all of your medical conditions, including if you:
Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Do not take any other uric acid lowering drug, such as allopurinol, febuxostat (Uloric), or probenecid, while receiving KRYSTEXXA.
KRYSTEXXA is recommended to be given with another prescription medicine called methotrexate. KRYSTEXXA may also be used alone. You and your doctor will decide the treatment that is right for you.
Prior to your treatment with KRYSTEXXA, your doctor may give you medicine to help reduce your risk of getting gout flares or an allergic reaction. Take these medicines as directed by your doctor or nurse. Your doctor will also test your uric acid levels prior to each treatment to monitor your response to KRYSTEXXA.
Your gout flares may increase in the first 3 months when you start receiving KRYSTEXXA. It’s important to understand that this is happening because KRYSTEXXA is breaking down uric acid in your body. Do not stop receiving KRYSTEXXA even if you have a flare, as the amount of flares will decrease after 3 months of treatment. Your doctor may give you other medicines to help reduce your gout flares for the first few months after starting KRYSTEXXA.
