Prednisolone vs. Prednisone: What's the Difference?
If you or a loved one have been diagnosed with an inflammatory condition or an autoimmune disorder, your doctor may prescribe a corticosteroid medication for treatment.
Among the most commonly prescribed corticosteroids are Prednisolone and Prednisone. Although they have many similarities, they aren't the same medications.

What are corticosteroids?
Corticosteroids, or steroids, are synthetic versions of the cortisol hormone, which is usually produced by the adrenal glands in the body.
Typically prescribed to reduce inflammation and suppress the immune system, Corticosteroids are used to treat both short-term and chronic conditions such as:
Allergies (hay fever)
Asthma
Hives
Eczema
Gout
Inflammatory bowel diseases (IBD), like Crohn's disease and ulcerative colitis
Chronic obstructive pulmonary disease (COPD)
Autoimmune diseases, like Addison's disease or hypothyroidism
Multiple sclerosis (MS)
What are the main differences between Prednisolone and Prednisone?
While Prednisolone(Millipred) and Prednisone are both used to treat inflammatory and autoimmune conditions, chemically, they are different.
Prednisone is a prodrug, an inactive medication that activates after the drug enters the body. Once the liver metabolizes Prednisone, it's turned into its active form, Prednisolone, to cross the cell membrane.
On the other hand, Prednisolone is the active form of the drug and can immediately infiltrate the cell membrane to suppress inflammatory and immune response markers.
In addition, both corticosteroids are available in different dosages and administration types.
Prednisolone- Available in ophthalmic drops, injectable solutions, and oral formulations. Solutions come in 5 mg/ml, 10 mg/ml, and 15 mg/ml concentrations, whereas oral formulations are available in 5 mg tablets and 10 mg, 15 mg, and 30 mg disintegrating tablets.
Prednisone- Available in oral (2.5 mg, 5 mg, 10 mg, 20 mg, and 50 mg tablets) and oral solutions.
What are the side effects of Prednisolone and Prednisone?
Prednisolone and Prednisone have very similar side effects, including:
Acne
Insomnia
Weight gain
Fluid retention and swelling
High blood pressure
High blood sugar
Mood changes
Muscle weakness
Stomach pain
When taken for an extended period or at a higher dose, more severe side effects may occur, such as:
Eye problems (like glaucoma or cataracts)
Bone loss
Osteoporosis
Muscle weakness
Thinning of the skin
Impaired wound healing
Pancreatitis
Behavior changes
Stomach ulcers
Heart issues, such as congestive heart failure (CHF)
Growth suppression in children
If you experience any of these, you should immediately seek medical attention.
Do either Prednisolone or Prednisone have adverse drug interactions?
Both drugs have adverse drug interactions, so always discuss your medical history and current medication list with your healthcare provider before starting either.
Prednisolone and Prednisone can cause drug interactions when they are taken in combination with::
NSAIDs, such as Advil, Ibuprofen, and Meloxicam
Medications containing ritonavir, such as Paxlovid and some HIV medications
Immune suppressants, such as Prolia
Diuretics (water pills), such as Torsemide
Azole antifungals, such as Ketoconzale
Certain diabetic (Type 2) medications, such as Metformin
Blood thinners (anticoagulants), such as Warfarin
Live vaccines, such as the MMR (measles, mumps, and rubella) and rotavirus vaccines
Please note: this is not an inclusive list. Some supplements, vitamins, food, and beverages are known to have negative reactions when taken with Prednisolone and Prednisone.
Can Prednisolone and Prednisone be taken together?
Since Prednisolone and Prednisone are in the same class of medications, they shouldn't be taken together. By taking them simultaneously, you will increase the risk of severe side effects without providing additional benefits.
How much do Prednisolone and Prednisone cost?
Prednisolone and Prednisone have generic options, meaning most health insurance plans usually cover them. It's always best to compare your insurance plan's out-of-pocket prescription costs with a pharmacy savings card like CareCard.
Which drug is more effective: Prednisolone or Prednisone?
These two drugs share similarities and effectiveness in treating various short-term and long-term health conditions. The most significant difference between Prednisolone and Prednisone is how they're taken. Reviewing options and costs with your physician can help you decide which is right.
