Celestone Soluspan is the brand name for betamethasone sodium phosphate and betamethasone acetate injectable suspension, a combination corticosteroid medication used to reduce inflammation and suppress the immune response across a wide range of medical conditions. It contains two forms of betamethasone: a rapidly absorbed soluble salt (sodium phosphate) for fast onset of action, and a slowly absorbed depot salt (acetate) for sustained, long-lasting relief.
Available as a 6 mg/mL sterile aqueous suspension in a 5 mL multi-dose vial, Celestone Soluspan is manufactured by Organon and has been used in clinical practice since 1963. It is a prescription-only medication administered by a healthcare professional — it is not designed for patient self-injection.
FDA-approved indications include severe allergic conditions, skin diseases, endocrine disorders, inflammatory joint and soft tissue conditions (intra-articular use), dermatologic lesions (intralesional use), rheumatic disorders, gastrointestinal conditions, nervous system conditions including MS exacerbations, hematologic disorders, and palliative management of certain cancers.

Celestone Soluspan works through its active ingredient betamethasone, a synthetic glucocorticoid. Once absorbed, betamethasone crosses cell membranes and binds to intracellular glucocorticoid receptors (GRs) found in virtually every cell type in the body. The drug-receptor complex travels to the cell nucleus, where it modulates gene expression — activating anti-inflammatory genes and suppressing pro-inflammatory ones.
Key mechanisms of action include: suppression of inflammatory mediator synthesis (prostaglandins, leukotrienes, cytokines); reduction of capillary permeability (reducing swelling and redness); inhibition of immune cell migration to inflammatory sites; stabilization of lysosomal membranes; and control of protein synthesis rates. These multi-level actions produce broad, potent anti-inflammatory and immunosuppressive effects.
What makes Celestone Soluspan uniquely effective is its biphasic pharmacokinetic profile. Betamethasone sodium phosphate (soluble) is absorbed rapidly, providing fast onset within hours. Betamethasone acetate (depot) dissolves slowly from the injection site over days to weeks, extending anti-inflammatory activity. This dual-component design is found in no other FDA-approved corticosteroid injection.

Celestone Soluspan has a findability score of 45 out of 100, reflecting intermittent supply disruptions that affect availability across pharmacies and medical distributors. While the medication is actively manufactured by Organon and an FDA-approved generic is available from American Regent, supply is geographically uneven. Drug Shortage Alert Warnings have been active for this product in 2026, and medical distributors including AmerisourceBergen, McKesson, and Cardinal Health have experienced periodic stock shortfalls.
Supply challenges are structural: a complex dual-salt formulation limits the number of manufacturers capable of producing it; thin profit margins on generic injectables reduce investment in redundant capacity; and demand spikes occur when other corticosteroids like methylprednisolone (Depo-Medrol) face their own shortages. The result is an environment where some pharmacies maintain steady stock while others frequently run out.
If you're having difficulty finding Celestone Soluspan at your pharmacy, medfinder calls pharmacies in your area to identify which ones have it in stock and can fill your prescription, then texts you the results. This eliminates hours of manual calling.
Celestone Soluspan is not a DEA-controlled substance, so no special DEA scheduling registration is required to prescribe it. Any licensed healthcare provider with prescriptive authority can write a prescription. However, the injection itself must be administered by a qualified healthcare professional using appropriate sterile technique.
Providers who commonly prescribe and administer Celestone Soluspan include:
Telehealth providers can issue a prescription for Celestone Soluspan, but the injection must be administered in person. Telehealth consultation may be useful for initial assessment and referral to an in-person provider for the procedure.
No. Celestone Soluspan is not a DEA-controlled substance and is not assigned a Schedule I through V designation. It is a prescription-only medication (requiring a valid prescription from a licensed prescriber), but it does not carry the special prescribing restrictions, refill limitations, or recordkeeping requirements that apply to scheduled controlled substances like opioids, benzodiazepines, or stimulants.
Any licensed healthcare provider with prescriptive authority can prescribe Celestone Soluspan without DEA registration (beyond standard state licensure). Prescriptions can be refilled according to standard medical practice and state pharmacy laws. However, because Celestone Soluspan is typically administered by a healthcare professional in a clinical setting (not a self-administered take-home medication), the prescription and dispensing workflow may differ from typical oral medications.
The most commonly reported side effects of Celestone Soluspan include:
Know what you need? Skip the search.
Triamcinolone Acetonide (Kenalog)
Most widely used substitute for intra-articular and soft tissue injections. Provides sustained depot anti-inflammatory effect. Lacks Celestone Soluspan's rapid-onset component.
Methylprednisolone Acetate (Depo-Medrol)
Common alternative for intra-articular, intrabursal, and IM use. Also faces periodic supply disruptions. Available in multiple concentrations (20, 40, 80 mg/mL).
Dexamethasone Sodium Phosphate (Decadron)
Fast-acting, non-particulate corticosteroid. Provides rapid effect without sustained depot. Good substitute for IM systemic use; not ideal for joint injections requiring depot effect.
Prednisone (oral)
Oral corticosteroid option for systemic indications when parenteral therapy is unavailable. Dose conversion: betamethasone 0.6 mg ≈ prednisone 5 mg. Cannot substitute for intra-articular injections.

Warfarin (Coumadin)
majorCorticosteroids can alter anticoagulant effect; monitor INR closely after injection.
Live Vaccines (MMR, varicella, nasal flu, rotavirus)
majorImmune suppression may reduce vaccine effectiveness or cause vaccine-strain infection. Avoid live vaccines during active corticosteroid therapy.
Amphotericin B
majorCombined use associated with cardiac enlargement and congestive heart failure.
NSAIDs (ibuprofen, naproxen, aspirin, celecoxib)
moderateAdditive risk of GI ulceration and bleeding when combined with corticosteroids.
Macrolide Antibiotics (erythromycin, clarithromycin)
moderateCYP3A4 inhibition increases betamethasone blood levels; may amplify effects and side effects.
Oral Contraceptives (estrogen-containing)
moderateEstrogen may increase corticosteroid levels by inhibiting metabolism and increasing protein binding.
Potassium-Depleting Diuretics (furosemide, HCTZ)
moderateAdditive potassium depletion; monitor electrolytes for hypokalemia.
CYP3A4 Inducers (rifampin, phenytoin, carbamazepine)
moderateAccelerate betamethasone metabolism, potentially reducing efficacy. Dose adjustment may be needed.
Diabetes Medications (insulin, metformin, sulfonylureas)
moderateBetamethasone raises blood glucose; diabetes medication doses may need temporary adjustment.
Celestone Soluspan has been a trusted anti-inflammatory injectable for over 60 years — and for good reason. Its unique dual-component formulation provides both rapid onset and sustained anti-inflammatory action that no other FDA-approved corticosteroid injection replicates. It remains a first-choice option for intra-articular injections, bursitis treatment, intralesional procedures, and parenteral corticosteroid therapy when oral steroids are not feasible.
Supply disruptions are a real and ongoing challenge for this medication in 2026. Patients and providers alike need to be proactive — sourcing both brand and generic from multiple distributors, having substitution protocols in place, and ensuring patients have tools to find their prescription when availability is limited in their area.
If you or your patient needs help locating Celestone Soluspan at a pharmacy, medfinder calls pharmacies in your area to find which ones have it in stock and texts you the results. It covers all medications — not just shortage drugs.
