7 Surprising Facts About Multiple Sclerosis
What Is Infusion Therapy?
Infusion therapy is a treatment in which medication is sent directly into the bloodstream intravenously (IV, through a vein) using a central venous catheter (central line).
A central line is much longer than a typical IV. It is placed in a major vein near the heart or just inside the heart. Central lines can be used if a person needs multiple IV treatments.
Infusions are given in place of certain oral medications since traveling through the digestive system can make the drugs less effective. The lines are also used when medication needs to be administered at a specific pace.
Before, During, and After Treatment
IV infusion therapy is usually done in your doctor’s office or in the hospital. Before starting your infusion, you will be prepped for the IV insertion. You will also receive medication such as anantihistamine, corticosteroid, and a fever reducer to prevent infusion-related side effects.
Once the treatment is over, the IV will be removed and you will be monitored for up to one hour for infusion reactions.If none occurs, you will be able to go home and return to your usual activities.
Infusion-Related ReactionsIf you experience signs or symptoms of an infusion-related reaction, such as hives, a rash, coughing or wheezing, unordinary tiredness, headache, nausea, redness in the face, or shortness of breath, in the first 24 hours after your infusion, call your doctor immediately. While some reactions are not medical emergencies, others could be.

While some reactions are not medical emergencies, others could be.
Timing of IV Appointments
The timing of IV appointments will vary greatly depending on the medication that you are taking. For example, one medication may take up to four hours while another might only take one to two hours.
The length of your infusion will be based on the medication that you are taking. Other factors related to the specifics of your MS will also be taken into account when determining the duration of your infusion treatments.

Possible Side Effects
As with most medical treatments, infusions for MS do come with a risk for side effects. Each DMT that is used for MS has its own possible adverse effects. Common infusion side effects include:
Tysabri, Tyruko (Natalizumab)
The common side effects of natalizumab are:
Serious Side Effects of NatalizumabThere are also some serious side effects that can occur with Tysabri and Tyruko, including:Progressive multifocal leukoencephalopathy(a potentially deadly brain infection)Liver damage or disease

There are also some serious side effects that can occur with Tysabri and Tyruko, including:Progressive multifocal leukoencephalopathy(a potentially deadly brain infection)Liver damage or disease
There are also some serious side effects that can occur with Tysabri and Tyruko, including:
Lemtrada (Alemtuzumab)
Side effects of Lemtrada can be mild or severe. Common symptoms of Lemtrada include:
More serious side effects can also occur with people taking Lemtrada, including:

Novantrone (Mitoxantrone)
Most side effects of Novantrone are mild and include:
In some cases, Novantrone can cause serious side effects that require medical attention, such as:
Ocrevus (Ocrelizumab)
Ocrevus can have common and more serious side effects. Common side effects can include:

Frequently Asked QuestionsInfusions for MS are generally considered safe but there is always a risk that you may experience an infusion reaction or side effects. Talk to your healthcare provider about your concerns. A doctor will help you make an informed decision about your care.Getting a needle inserted for a central line before you start the infusion might be uncomfortable or painful, however, the infusion itself is not painful. Once the medication is being administered, it’s unlikely that you will experience any discomfort or pain.Your care team will likely encourage you to eat before an infusion. Foods that are high in nutrients will be good for your body while you undergo infusion therapy. No specific precautions, dietary or otherwise, need to be taken before an MS infusion treatment session.It can be hard to determine how you will feel following an infusion. You may feel light-headed or fatigued, but since everyone reacts differently to medications, it’s important that you bring someone with you to your first infusion. They can provide support and give you a ride home when your treatment is done.
