For individuals living with multiple sclerosis (MS), flare-ups—also referred to as relapses, exacerbations, or attacks—are challenging periods marked by the re-emergence or worsening of symptoms. In these instances, healthcare professionals often prescribe corticosteroids to expedite recovery and alleviate symptom severity. While not every flare-up requires steroid treatment, these medications are critical for more serious episodes that significantly disrupt daily functioning.

Understanding Corticosteroid Treatment

The steroids commonly used for MS are classified as glucocorticoids, which are part of the larger corticosteroid family. Their function mirrors that of natural glucocorticoid hormones, assisting in the closure of the blood-brain barrier to prevent inflammatory cells from entering the central nervous system. This mechanism helps in controlling inflammation and mitigating MS symptoms.

Typically, high-dose steroids are administered through intravenous (IV) routes once daily over a span of 3 to 5 days, often in a clinical setting. In certain situations, hospitalization may be necessary for individuals with multiple health concerns. Following IV treatment, a tailored oral corticosteroid regimen may continue for an additional 1 to 2 weeks, tapering off gradually.

Types of Steroids for Multiple Sclerosis

Methylprednisolone

• Available as an oral medication (Medrol)
• Administered via intramuscular, intraarticular, or subcutaneous injection (Depo-Medrol, Solu-Medrol)
• Given through intravenous infusion (Solu-Medrol)

Solu-Medrol is typically used for acute flare-ups due to its potent effects. The standard dosage varies from 500 mg to 1,000 mg daily, with patients receiving treatment for about an hour per day over 3 to 7 days. Side effects may include a temporary metallic taste in the mouth.

Prednisone

Prednisone, an oral glucocorticoid available under various brand names, is often utilized in place of IV steroids or to taper off after IV administration. A common tapering approach includes reducing the dosage by 2.5 to 5 mg every 3 to 7 days until reaching maintenance levels.

Prednisolone

Prednisolone is offered in both oral tablet and syrup forms. Recent studies indicate that tapering prednisolone post-IV treatment may have minimal impact on recovery, but may increase side effects like appetite enhancement and weight gain.

Dexamethasone

Administered orally or via injection, dexamethasone has demonstrated efficacy when prescribed at 30 mg daily over a week, followed by a reduced dosage for up to a month, tailored by medical professionals.

Betamethasone

Available as an injectable medication, betamethasone is similarly initiated at 30 mg daily, tapering to 12 mg every other day post one week.

Efficacy of Steroid Treatments

Corticosteroids are not a long-term solution nor do they alter the trajectory of MS. However, they are proven to enhance recovery speed during flare-ups. Since MS manifestations differ widely among individuals, the responsiveness to steroid treatment may vary. Recent studies indicate that oral corticosteroids can serve as viable substitutes to IV formulations, particularly where access to infusions is problematic.

Potential Side Effects

Immediate Side Effects

While many respond well to high-dose steroids, side effects can occur, some of which may offer immediate sensations like increased energy and mood alterations:

• Acne
• Facial flushing
• Depression
• Fluid retention leading to swelling
• Insomnia
• Increased appetite
• Metallic taste

Long-Term Side Effects

Long-standing corticosteroid usage may lead to complications such as:

• Osteoporosis
• Cataracts
• Increased diabetes risk
• Weight gain

Considerations During Pregnancy

Research highlights that corticosteroid use during the first trimester elevates miscarriage risks. Treatment should only be considered for severe flare-ups affecting daily life, with certain steroids like dexamethasone and betamethasone contraindicated for pregnant patients.

Weaning Off Steroids Safely

As corticosteroids can hinder natural cortisol production, abrupt cessation or rapid tapering can induce withdrawal symptoms. Patients are advised to closely follow medical guidance during this process to mitigate symptoms including:

• Fatigue
• Muscle aches
• Confusion
• Nausea

Conclusion

While corticosteroids are an invaluable tool for addressing acute MS flare-ups, they do not provide a cure for the disease. It is essential to collaborate with your healthcare provider regarding the role of steroids in your treatment plan. Considerations include the impact of flare-ups on your daily life, steroid administration methods, potential side effects, and any interactions with current medications. Discuss these factors thoroughly on your next visit to a neurologist, ensuring preparedness for effective management of future flare-ups.
