Alternatives to Millipred If You Can't Fill Your Prescription

Millipred (prednisolone) shortages are a real and recurring problem. If your pharmacy is out of stock and you need your medication, the good news is that prednisolone isn't the only corticosteroid that can treat your condition. Several alternatives are available — but it's critical to understand how they differ before switching. Never change corticosteroids on your own. Always work with your prescriber.

Why Prednisolone Specifically? What Makes It Unique

Prednisolone is already in its active form when you take it. Unlike prednisone, which your liver must convert into prednisolone before it works, prednisolone gets to work immediately. This makes it especially useful for patients with liver disease, and for situations where predictable absorption is important.

Additionally, prednisolone oral liquid is one of the few corticosteroid formulations available in a palatable, pediatric-friendly liquid form — making it particularly important for children who can't swallow tablets.

Alternative #1: Prednisone — The Closest Substitute

Prednisone is the most commonly prescribed oral corticosteroid in the United States and the closest substitute for prednisolone. It's a prodrug — your liver converts it into prednisolone after you swallow it. For most patients with normal liver function, the two drugs are essentially equivalent in effect.

Dose equivalency: 5 mg prednisone ≈ 5 mg prednisolone (1:1 ratio)

Forms available: Tablets (1 mg, 2.5 mg, 5 mg, 10 mg, 20 mg, 50 mg), oral solution, and Intensol concentrated solution

Availability: Generally widely available; rarely in shortage

Caution: Not ideal for patients with significant liver disease. Oral liquid form may be limited for pediatric use.

Alternative #2: Dexamethasone — For Children and Short Courses

Dexamethasone is a long-acting, high-potency corticosteroid — roughly 6 to 7 times more potent than prednisolone, milligram for milligram. Its longer duration of action (36–72 hours) means fewer doses may be needed, which has made it a popular alternative for conditions like croup and pediatric asthma flares.

Dose equivalency: 0.75 mg dexamethasone ≈ 5 mg prednisolone (approximately 6–7x more potent)

Forms available: Tablets, oral solution (0.5 mg/5 mL, 1 mg/mL), injection, elixir

Best for: Children who need liquid, croup, short-course asthma treatment, conditions where minimal doses are preferred

Caution: Long half-life makes it less suitable for alternate-day tapering regimens. Requires careful dose conversion.

Alternative #3: Methylprednisolone — Similar Potency, More Forms

Methylprednisolone is slightly more potent than prednisolone and has less mineralocorticoid activity (meaning less sodium retention and fluid retention). It's available in tablet form (including the familiar Medrol Dosepak) and injectable forms, though injectable methylprednisolone has also experienced its own shortage issues in recent years.

Dose equivalency: 4 mg methylprednisolone ≈ 5 mg prednisolone

Forms available: Tablets (2 mg, 4 mg, 8 mg, 16 mg, 32 mg), injection (Solu-Medrol, Depo-Medrol)

Caution: Injectable forms have had their own supply disruptions. No widely available oral liquid form.

Alternative #4: Hydrocortisone — For Adrenal Replacement

Hydrocortisone is the synthetic form of the body's natural cortisol. It's less potent than prednisolone — roughly one-quarter the strength — meaning you'd need much higher doses to match prednisolone's anti-inflammatory effect. It's primarily used for adrenal insufficiency replacement therapy rather than as a strong anti-inflammatory agent.

Dose equivalency: 20 mg hydrocortisone ≈ 5 mg prednisolone

Best for: Adrenal insufficiency replacement therapy, Addison's disease

A Quick Comparison Chart

Here's a simplified potency reference based on anti-inflammatory equivalency:

Prednisolone 5 mg = Prednisone 5 mg = Methylprednisolone 4 mg = Dexamethasone 0.75 mg = Hydrocortisone 20 mg

These equivalencies reflect anti-inflammatory potency. They do not account for differences in mineralocorticoid effects, duration of action, or clinical context. Always use your doctor's guidance for any dose conversion.

Questions to Ask Your Doctor About Switching

Why was prednisolone specifically chosen for my condition?

Do I have any liver disease that makes a direct-acting steroid preferable?

Can my child swallow tablets, or do I need a liquid formulation?

Is dexamethasone oral solution available and appropriate for my condition?

What dose adjustment would be needed if switching to a different steroid?
