Infusion Therapy Treatment for Giant Cell Arteritis

Infusion Therapy Treatment for Giant Cell Arteritis

What is giant cell arteritis (GCA)?

Giant cell arteritis (GCA) is an inflammatory condition that affects the blood vessels. It is the most prevalent vascular disorder among people over 50 years old, with an average onset age of 72. It can cause pain in the head, joints, face, and arms, and can even lead to vision impairment and blindness. Inflammation due to GCA constricts and blocks blood vessels, interrupting blood flow. GCA is often associated with and can overlap with polymyalgia rheumatica (PMR). Left untreated, GCA can cause blindness, stroke, and aneurysms.

The good news, however, is that GCA is a treatable condition, and most patients experience relief after only a few days of treatment. Traditional treatment options include receiving steroids such as prednisone and other corticosteroids. However, more recently infusion therapy has been used to treat GCA effectively, especially in patients who cannot take oral medications or for whom oral medication has proven ineffective.

How Infusion Therapy Works for Giant Cell Arteritis

Infusion therapy for GCA works by administering medications either intravenously (IV) or subcutaneously (under the skin). This allows for quick and efficient absorption of the medication into the bloodstream.

Talk to your healthcare provider to determine which kind of infusion therapy option is best for you.

What to Expect

Infusion therapy at Infusion Associates is meant to make you feel at home during your treatments. Far from the cold, sterile nature of a hospital, our rooms are equipped with blankets, free Wi-Fi, big-screen TVs, and more. You can even listen to music or read a book from a comfortable armchair while receiving your infusion treatments.

The duration of the infusion therapy will depend on what medications are being administered and your specific needs, but in general these take anywhere from 30 minutes to a few hours. A doctor or nurse practitioner will be monitoring the infusion throughout the duration of your treatment.

Medications Used to Treat Giant Cell Arteritis

The most common infusion medication used to treat GCA is ACTEMRA® (tocilizumab). ACTEMRA® has been specifically indicated by the FDA for the treatment of GCA. Whereas traditional prescriptions for GCA consist primarily of steroidal treatments (prednisone), recent studies have shown that a greater number of patients experienced sustained remission than patients taking only prednisone. At present, only subcutaneous (under-the-skin) infusions of ACTEMRA® have been approved by the FDA for GCA treatment. Intravenous (IV) administration of ACTEMRA® has been approved for rheumatoid arthritis but not yet for GCA. To learn more about ACTEMRA®, visit the manufacturer’s website.
