About 10%-20% of people with multiple sclerosis (MS) receive baclofen to control their spasticity, but up to half of patients stop the medication in the first six months, a large Swedish population-based study shows. The high rates of discontinuation suggest baclofen has “a low success rate of…

My hips have hurt for several years. Right now, it’s just a dull ache. But there have been times when it has been a shooting pain. Hip pain isn’t necessarily connected to your multiple sclerosis (MS), but it could be. It might be caused by alterations in your…

More than four years of treatment with Gilenya (fingolimod) did not cause significant swelling of the macula — a part of the retina, found in the back of the eye, and important for visual clarity — in people with relapsing-remitting multiple sclerosis (RRMS), a small study showed. While…

Differences in the composition of the gut microbiome are associated with an altered risk of low immune cell counts as a side effect of treatment with the multiple sclerosis (MS) therapy Tecfidera (dimethyl fumarate). The findings provide further insights on how the gut microbiome — the billions of…

Consuming alcohol around dosing time could limit the effectiveness of Tecfidera (dimethyl fumarate) for multiple sclerosis patients, a recent study suggests. Results from the study, which involved lab and mouse experiments, showed alcohol inhibits an enzyme in the liver that’s necessary to break down Tecfidera’s main ingredient, dimethyl…

Almost two-thirds of a group of 108 secondary progressive multiple sclerosis (SPMS) patients being treated with Mayzent (siponimod) remained stable for at least one year, and about 1 in 5 of them showed improvements, a real-world study from Germany found. Nearly one-third of the total 227 SPMS patients evaluated…

The call from my urologist’s office came far later than I was expecting, in regards to my long-term chronic urinary tract infection (UTI). The call came in on my home phone, but luckily, someone else was around to answer it. I long ago gave up trying to answer that…

Treatment with Ocrevus (ocrelizumab) before or during pregnancy does not seem to increase the risk of major pregnancy or infant complications, with 79% of the pregnancies leading to live births, according to data from more than 2,000 women with multiple sclerosis (MS). The results were shared at the 38th…

This headline is a bit of a cheat. OK, it’s a big cheat. When you’ve been writing a column for five years, there’s immense satisfaction when you’ve finished it each week. There’s even more when it’s passed through the editing process. Sometimes this can get somewhat tricky. The trouble is…

The U.S. Food and Drug Administration (FDA) has placed a partial clinical hold on Phase 3 trials testing the investigational therapy tolebrutinib in people with multiple sclerosis (MS) and myasthenia gravis based on reports of medication-induced liver injury. Under the clinical hold, new enrollment at U.S. sites…

A short course of high-dose methylprednisolone was associated with signs of mild liver injury in nearly 3% of multiple sclerosis patients given this treatment, according to a study in Iran. Notably, a history of alcohol abuse and hyperlipidemia — higher-than-normal blood levels of fatty molecules such as cholesterol — were…

Treatment with the approved multiple sclerosis (MS) therapy dimethyl fumarate (DMF) did not affect the function of the thyroid gland, an organ that secretes hormones to regulate metabolism, a medical records study concluded. Screening for thyroid problems is not needed for people with MS considered for DMF therapy, the…

Persistent use of a single disease-modifying therapy (DMT) over a three-year period was low among people with relapsing forms of multiple sclerosis (MS), a U.S. study found. DMT discontinuations or switches were initiated in some cases by prescribers, specialty pharmacists, or patients for reasons that included treatment side…

Reports of psoriasis — an autoimmune skin disease that shares some biological processes with multiple sclerosis (MS) — are disproportionally high among MS patients on therapies that deplete B-cells, according to a U.S. study based on patient adverse event data. Conversely, patients on Tysabri (natalizumab), glatiramer acetate (sold…

Plegridy (peginterferon beta-1a), an approved treatment for relapsing multiple sclerosis (MS), is detected at minimal concentrations in the breast milk of patients using the therapy postpartum, a small study showed. This is in line with label updates on Plegridy and other interferon beta therapies in Europe and…

Maternal or paternal exposure prior to conception to the multiple sclerosis (MS) therapy Aubagio (teriflunomide) does not seem to increase the risk of adverse pregnancy events, including miscarriage, preterm birth, small newborn size, or malformations, according to the results of a recent Danish study. About…

“I close my eyes/ Only for a moment then the moment’s gone/ All my dreams pass before my eyes, a curiosity.” — Kansas, “Dust in the Wind”  The dark cloud of fatigue first swept through my mind toward the end of 2018. I was no stranger to physical fatigue,…

Multiple sclerosis (MS) treatments belonging to the class of sphingosine 1-phosphate (S1P) receptor modulators — such as Mayzent (siponimod) and Gilenya (fingolimod) — may be associated with a greater likelihood of skin cancer, results from a real-world study suggest. The association was the greatest for a form of…

“Hey, man, I’m alive. I’m taking each day and night at a time/ I’m feeling like a Monday but someday I’ll be Saturday night.” — Bon Jovi Multiple sclerosis (MS) medications can generally be separated into two categories: disease-modifying therapies (DMTs) and those that help to manage symptoms. While…

A little over a year ago, I wrote about whether people with multiple sclerosis (MS) should get a COVID-19 vaccine. I was anxious to be vaccinated as soon as I could, but I was also concerned about how the vaccines would affect someone with MS. Would the side effects…

It was five years ago, Dec. 5, 2016, that I scootered into the office of Dr. Heidi Crayton, my neurologist, and plopped into a soft, brown leather recliner. Day 1 of Round 1 of my Lemtrada (alemtuzumab) infusions was about to begin. I’d prepped for this day: two days…

Side effects upon receiving the COVID-19 vaccine in people with multiple sclerosis (MS) are similar to those reported in the general population, and patients on certain disease-modifying therapies are less likely to have vaccine reactions, a survey-based study found. The findings provide “a reassuring picture” for those who feel hesitant about…

I’m hurtin’ a little today. I have mild muscle aches, a bit more fatigue than usual, and dragging legs. It could just be a bad MS day, or it could be the result of my COVID-19 booster shot a couple days ago.  I received a third shot of the Moderna…

One year of Ocrevus (ocrelizumab) treatment does not increase the risk for a rare brain infection — called progressive multifocal leukoencephalopathy (PML) — in people with multiple sclerosis (MS), a study suggests. The study, “Risk Assessment of Progressive Multifocal Leukoencephalopathy in Multiple Sclerosis Patients during…

I am having an MS relapse, my first in three years. In the first two years after I was diagnosed with relapsing-remitting MS in early 2017, I relapsed every two or three months. It got to the point that I couldn’t tell where one relapse began and another ended.

Anti-CD20 antibody therapies that target B-cells are highly effective for reducing the risk of relapses in people with relapsing-remitting multiple sclerosis (RRMS), a new analysis confirms. The analysis did not find any significant differences in efficacy or safety among the anti-CD20 therapies currently approved to treat RRMS, though…

Lemtrada (alemtuzumab) does not have a substantial effect on blood pressure or platelet counts, and does not lead to bleeding in the brain of multiple sclerosis (MS) patients, according to a small Belgian study. The findings contrast with previous studies showing an increase in blood pressure, stroke, and…

Skin Reactions ‘Frequent’ With Mavenclad, Real-world Study Finds I regularly see people posting on social media about having a rash or itchy skin, or losing hair while taking Mavenclad. Researchers in this study say these side effects aren’t mentioned in the risk management plans for this disease-modifying therapy. Therefore,…

Skin reactions are common among relapsing-remitting multiple sclerosis (RRMS) patients being treated with oral Mavenclad (cladribine), affecting about one-third of the people evaluated in a real-world study in Germany. These findings suggest the need for careful clinical surveillance to rapidly diagnose and possibly treat skin problems stemming from Mavenclad’s use,…

The U.S. Food and Drug Administration (FDA) has rejected an application requesting the expansion of Aubagio (teriflunomide) for the treatment of children and adolescents, ages 10 to 17, with relapsing forms of multiple sclerosis (MS). “The FDA deemed the data submitted were not sufficient to obtain approval of…
