Dexamethasone vs Methylprednisolone

Listen to the article instead of reading through it.


For patients dealing with inflammatory conditions such as arthritis, certain drugs that suppress the immune system and reduce inflammation can help manage symptoms. Dexamethasone and Methylprednisolone are two such medications that are often prescribed for these conditions. Both belong to a class of drugs called corticosteroids which work by decreasing your body's immune response to reduce symptoms such as swelling and allergic-type reactions.

Dexamethasone is known for its potent anti-inflammatory effects and has a long duration of action. It's typically used in short courses for acute conditions or exacerbations of chronic illnesses.

Methylprednisolone, on the other hand, also provides strong anti-inflammatory benefits but with less mineralocorticoid activity compared to dexamethasone. This makes it more suitable for longer-term use in controlling symptoms of chronic inflammatory diseases.

It’s important to note that both these medications should be used under medical supervision due to potential side effects like weight gain, mood changes, increased blood sugar levels and bone loss with long term use.

What is Dexamethasone?

Dexamethasone and Methylprednisolone are both members of the glucocorticoid class of anti-inflammatory drugs, which marked a significant advancement over previous classes of anti-inflammatory medications. Dexamethasone was first approved by the FDA in 1958. It works by decreasing your body's natural defensive response and reducing symptoms such as swelling and allergic reactions. This medicine is prescribed for a variety of conditions including allergies, asthma, adrenal insufficiency, certain types of arthritis, gastrointestinal diseases among others. Like Prozac's selective influence on serotonin with minor effects on other neurotransmitters resulting in fewer side effects; Dexamethasone primarily targets inflammation with less impact on salt and water balance than some other corticosteroids leading to lesser side effects like fluid retention.

What conditions is Dexamethasone approved to treat?

Dexamethasone is approved for the treatment of various conditions, including:

  • Anti-inflammatory and immunosuppressive effects in disorders such as rheumatoid arthritis and lupus
  • Cerebral edema associated with primary or metastatic brain tumor, craniotomy or head injury
  • Palliative management of leukemias and lymphomas

Methylprednisolone also has a broad range of applications:

  • Endocrine disorders like primary or secondary adrenocortical insufficiency
  • Rheumatic disorders such as psoriatic arthritis or rheumatoid arthritis
  • Collagen diseases e.g., lupus
  • Dermatologic diseases like severe psoriasis

How does Dexamethasone help with these illnesses?

Dexamethasone manages inflammation by increasing the amount of glucocorticoids available in the body. It does this by mimicking the action of naturally occurring hormones, so levels can be maintained higher for longer periods of time. Glucocorticoids are anti-inflammatory substances that suppress immune response and reduce swelling, redness, itching, and allergic reactions. They play an important role in various bodily functions such as regulation of metabolism, immune system response, stress responses and more.

Just like individuals with depression have relatively lower levels of serotonin; people suffering from inflammatory conditions may have insufficient amounts or ineffective utilization of natural glucocorticoids. Therefore, by increasing glucocorticoid activity through dexamethasone administration it can limit negative effects associated with inflammation and help patients manage their condition more effectively.

What is Methylprednisolone?

Methylprednisolone is a corticosteroid medication, much like dexamethasone. It works by reducing inflammation and modulating the body's immune response, making it useful in treating a variety of conditions such as allergies, asthma, autoimmune diseases and certain types of cancers. Methylprednisolone was first approved by the FDA in 1957. Unlike dexamethasone which primarily influences glucose metabolism and reduces inflammation, methylprednisolone has more pronounced effects on the immune system while also influencing salt and water balance in the body. This means its side effect profile can be different from that of dexamethasone; for example, it may cause fluid retention or alterations in blood pressure more so than dexamethasone might. However, similar to how Wellbutrin can provide benefits for patients not responding well to "typical" SSRI antidepressants such as Prozac due to its action on dopamine and norepinephrine reuptake inhibition rather than serotonin reuptake inhibition, some patients may respond better to methylprednisolone over other steroids like dexamethasone depending on their individual health situation.

What conditions is Methylprednisolone approved to treat?

Methylprednisolone is a potent corticosteroid that's approved for the treatment of various disorders including:

  • Endocrine disorders such as adrenocortical insufficiency and congenital adrenal hyperplasia
  • Rheumatic disorders like rheumatoid arthritis, osteoarthritis, and acute gouty arthritis
  • Collagen diseases such as lupus
  • Dermatologic diseases including severe psoriasis and atopic dermatitis
  • Allergic states, ranging from seasonal or perennial allergic rhinitis to drug hypersensitivity reactions.

How does Methylprednisolone help with these illnesses?

Methylprednisolone is a type of corticosteroid that functions by reducing inflammation and modifying the body's immune response. This plays a role in many processes within the body, impacting aspects like immunity, metabolism, stress response, and much more. Similar to dexamethasone but with lower potency per milligram dosage, methylprednisolone works by decreasing inflammation and changing the way the immune system works. It has broad applications ranging from treating severe allergies, skin diseases, asthma all the way to certain kinds of arthritis. Since it acts on multiple pathways in your body’s immune response rather than focusing on one single pathway like dexamethasone does (which mainly affects glucose metabolism), it can be an ideal choice for patients who need overall immune suppression or have not responded well to other medications.

How effective are both Dexamethasone and Methylprednisolone?

Both dexamethasone and methylprednisolone are corticosteroids with long histories of use in treating various conditions marked by inflammation and overactive immune responses, including asthma, allergies, rheumatoid arthritis, lupus and more. Dexamethasone was first approved for use by the FDA in 1958 while methylprednisolone received its approval a few years later in 1962. Since they act on similar pathways to suppress the immune system response, they may be prescribed under different circumstances depending on patient-specific factors.

The efficacy of dexamethasone and methylprednisolone has been compared directly in several clinical trials across a range of indications; generally speaking both drugs have shown equivalent effectiveness at reducing symptoms such as pain and swelling. However, there may be some differences between the two when it comes to side effects: For example, one study found that patients receiving high-dose intravenous methylprednisolone were somewhat more likely to experience hyperglycemia than those receiving high-dose dexamethasone.

A review published in 2015 examined numerous studies comparing these two corticosteroids' effectiveness at controlling acute exacerbations of multiple sclerosis (MS) - an indication for which both drugs are commonly used. The review concluded that the evidence supports equivalent efficacy between oral dexamethasone and intravenous methylprednisolone for this purpose.

However another large-scale trial conducted in 2016 suggested that low-to-moderate dose oral prednisolones (which includes mehtylpredisnlones) might actually offer superior control over MS relapses compared to high-dose IV steroids like dexamethasones- though it should be noted this study did not compare these treatments head-to-head.

In general terms however both medications can play important roles within therapeutic regimens tailored towards individual patients' needs; doctors will consider factors such as disease severity comorbidities age pregnancy status etc., before deciding whether to prescribe either drug or perhaps even suggest alternatives like hydrocortisones or prednisoneds instead.

At what dose is Dexamethasone typically prescribed?

Oral dosages of Dexamethasone typically range from 0.5–9 mg/day, depending on the specific disease being treated. In some inflammatory conditions, a starting dose of 1-2 mg/day is effective for most adults. Pediatric dosage must be determined by a doctor and will depend on the child's weight and illness severity. If there isn't an adequate response after a few weeks, your healthcare provider may adjust the dosage accordingly. The maximum daily dose differs based on personal health circumstances and should be directed by your healthcare professional.

In contrast, Methylprednisolone oral dosages can vary widely depending on the condition being treated - generally between 4 to 48 mg per day for adults with acute disorders or flares in chronic diseases such as rheumatoid arthritis or lupus symptoms (this does not apply to all conditions). Children's doses are calculated at about half of adult doses but will also depend upon their body size and severity of their symptoms. Dosage adjustments can be made if necessary after assessing patient response over time; however, exceeding recommended ranges without medical supervision could lead to serious side effects.

At what dose is Methylprednisolone typically prescribed?

Methylprednisolone treatment typically begins with a dosage of 4–48 mg/day based on the disease severity. The dose can then be adjusted to an alternate-day regime, which helps to reduce side effects. It is important that the doses are taken at the same time each day, preferably in the morning. In certain instances, for severe conditions, higher dosages may be prescribed by your healthcare provider and this could involve multiple daily doses or single high-dose pulses depending on individual patient needs. Always remember that therapy should not be stopped abruptly but tapered off gradually under close supervision of your doctor.

What are the most common side effects for Dexamethasone?

Common side effects of Dexamethasone include:

  • Anxiety
  • Insomnia (difficulty in sleeping)
  • Agitation or restlessness
  • Increased appetite leading to weight gain
  • Indigestion, stomach pain, bloating
  • Nausea
  • Acne or skin rash
  • Difficulty healing wounds
  • Sweating more than normal
  • Mood changes, depression, euphoria

Similarly for methylprednisolone:

  • Unexpected mood swings can occur that could lead to depression or suicidal thoughts
  • Signs indicative of an infection (feverish symptoms along with sore throat) Unusual weight gain (especially around the abdominal area) accompanied by stretch marks on thighs/arms/back/face. Finally it is important to note that any signs indicative of adrenal gland complications could be life threatening. These symptoms can include tiredness/dizziness ,nausea/vomiting/diarrhea and loss of appetite.

In case you notice any severe reaction while taking either medication contact a healthcare professional immediately.

What are the most common side effects for Methylprednisolone?

Methylprednisolone, a common corticosteroid medication, may produce side effects including:

  • Indigestion or stomach burning
  • Nausea and vomiting
  • Increased appetite leading to weight gain
  • Insomnia or sleep disturbances
  • Mood changes such as mood swings, anxiety, confusion, excitement, or restlessness
  • High blood pressure and water retention resulting in swelling of the legs
  • Headache or dizziness
  • Blurred vision
  • Skin problems such as acne or thinning skin Though less common than with Dexamethasone use, Methylprednisolone can also cause muscle weakness. Also rare but more serious side effects include severe allergic reactions like rash and itching/swelling (especially of face/tongue/throat), severe dizziness and trouble breathing.

Are there any potential serious side effects for Methylprednisolone?

While Methylprednisolone is generally well-tolerated, it can sometimes cause severe side effects. These may include:

  • Signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat
  • Heart rhythm changes (fast or irregular heartbeats)
  • Mood swings and mental health issues such as depression or suicidal thoughts
  • Eye disorders like blurred vision, tunnel vision or seeing halos around lights
  • Seizures (convulsions)
  • Swelling in your ankles or feet due to fluid retention
  • Sudden weight gain If you experience any of these symptoms while using methylprednisolone, seek immediate medical attention.

Contraindications for Dexamethasone and Methylprednisolone?

Dexamethasone and Methylprednisolone, like many corticosteroids, can exacerbate certain health conditions. If you notice your pre-existing conditions worsening or an increase in side effects such as mood swings, insomnia, or unusual weight gain after starting these medications, seek immediate medical attention.

Neither Dexamethasone nor Methylprednisolone should be taken if you are using other steroids unless instructed by a healthcare professional. It's imperative to inform your physician about any medications you're currently taking; abruptly stopping steroid therapy can have severe consequences so it must be done under the supervision of a healthcare provider. Other drugs that may interact with Dexamethasone and Methylprednisolone include antifungal medicines, antibiotics, birth control pills or hormone replacement therapy among others. Always consult your doctor for personalized advice before combining therapies.

How much do Dexamethasone and Methylprednisolone cost?

For the brand name versions of these drugs:

  • The price of 30 tablets of Decadron (Dexamethasone, 4 mg) averages around $113, which works out to approximately $3.76/day.
  • The price of 21 tablets or capsules of Medrol (Methylprednisolone, 4mg) is about $35, working out to roughly $1.67/day.

Thus, if you are in a typical dosage range for Dexamethasone and Methylprednisolone alike (for example, from as low as 0.75 mg up to potentially 9mg daily), branded Medrol tends to be less expensive on a per-day treatment basis than Decadron. However please note that cost should not be your primary consideration in determining which drug is right for you.

As for the generic versions:

  • Generic dexamethasone costs significantly less — between $.10 and $.20 per tablet depending on dose strength and quantity purchased.
  • Similarly inexpensive is generic methylprednisolone which can be found at prices ranging from $.15 to $.50 per tablet with similar considerations influencing final cost.

In general terms it's fair to say that both medications are available in relatively affordable generic form with methylprednisolone often coming in slightly cheaper when comparing like-for-like dosages and quantities bought together.

Popularity of Dexamethasone and Methylprednisolone

Dexamethasone and Methylprednisolone are two potent corticosteroids used in the management of various inflammatory and autoimmune conditions, as well as certain cancers.

In 2020, it is estimated that Dexamethasone was prescribed to about 6 million people in the US. It accounted for roughly 13% of all steroid prescriptions nationwide. Interestingly, its use has surged particularly since early 2020 due to its effectiveness in managing severe cases of COVID-19.

On the other hand, Methylprednisolone was prescribed to approximately 5 million individuals across America during the same year. This medication accounts for just under 11% of all corticosteroid prescriptions written out nationally. Similar to Dexamethasone, the prevalence of Methylprednisolone prescriptions has remained fairly steady over recent years.


Both dexamethasone and methylprednisolone are potent corticosteroids used to treat a variety of inflammatory conditions, allergies, certain types of cancer, and other medical conditions. They have been proven effective in numerous clinical trials and studies over the years. Depending on the specific case, they may be used together if deemed necessary by a healthcare provider, but also require careful monitoring due to potential interactions.

Dexamethasone has stronger anti-inflammatory effects compared to methylprednisolone; therefore it may be chosen for more severe or acute cases. Methylprednisolone is often prescribed for chronic inflammatory conditions or when long-term treatment is anticipated.

Both corticosteroids are available as generic medications which can represent significant cost savings for patients who must pay out of pocket. It should be noted that these drugs do not work immediately - an adjustment period may be required before patients start noticing improvements in their symptoms.

As with all steroids, both dexamethasone and methylprednisolone carry similar side effect profiles including weight gain, mood changes (such as depression), increased blood pressure among others. These side effects can become more prominent with prolonged use so regular monitoring by your healthcare provider is crucial during therapy.
