With any treatment that you take, there is a possibility you will experience side effects. These are secondary and unfavorable reactions that occur in response to a treatment. To help support your understanding of side effects that can occur while taking a DMT, we have grouped together some of the most common side effects related to different MS treatment types. Looking at the different MS treatments you can see that some side effects are common among all DMTs, whilst others are more specific to the type of DMT or are associated with the method of administration.
Risk of infection
Due to their influence on the immune system, all DMTs can increase your vulnerability to infection and reduce your ability to fight them off. As such, it’s important to monitor for signs of infection as a side effect following treatment with a DMT. Some of the main signs of infection to look out for include a fever, chills and swollen glands. Speak to your doctor or MS nurse immediately if you are experiencing any of these side effects.
Possible side effects associated with DMT method of administration
Side effects can also be directly related to how a treatment is administered. Some DMTs are taken orally in tablet form once or twice daily or are self-administered by injection. Others are administered by infusion, whereby the drug is given directly into a vein. This type of DMT is given in the clinical setting by a trained healthcare professional. Each method is associated with their own selection of side effects.
For example, DMTs given by injection are often self-administered on a regular basis and may result in a response at the DMT delivery site. Such side effects are called injection-site reactions and are usually mild. These include:
For DMTs administered by infusion, most of the side effects occur during and/or up to 24 hours after an infusion and are collectively known as infusion-associated reactions. Whilst they may differ between treatments, some common infusion-associated reactions include:
