For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 24208-0715-10. Same drug, same package — only the format differs.

📖 What it is MedlinePlus · NLM

Ophthalmic prednisolone reduces the irritation, redness, burning, and swelling of eye inflammation caused by chemicals, heat, radiation, infection, allergy, or foreign bodies in the eye. It sometimes is used after eye surgery. Prednisolone is in a class of medications called steroids. It prevents swelling and redness by changing the way the immune system works.

Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

🎯 Indications and Usage 126 words ▾

INDICATIONS AND USAGE Prednisolone sodium phosphate ophthalmic solution, 1% or 1/8% is for the treatment of steroid responsive inflammatory conditions of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe, such as allergic conjunctivitis, acne rosacea, superficial punctate keratitis, herpes zoster keratitis, iritis, cyclitis, selected infective conjunctivitis when the inherent hazard of steroid use is accepted to obtain an advisable diminution in edema and inflammation, corneal injury from chemical, radiation, or thermal burns, or penetration of foreign bodies.

Prednisolone sodium phosphate ophthalmic solution, 1%, is recommended for moderate to severe inflammations, particularly when unusually rapid control is desired. In stubborn cases of anterior segment eye disease, systemic adrenocortical hormone therapy may be required. When deeper ocular structures are involved, systemic therapy is necessary.

⏱️ Dosage and Administration 111 words ▾

DOSAGE AND ADMINISTRATION Depending on the severity of inflammation, instill one or two drops of solution into the conjunctival sac up to every hour during the day and every two hours during the night as necessary as initial therapy. When a favorable response is observed, reduce dosage to one drop every four hours. Later, further reduction in dosage to one drop three to four times daily may suffice to control symptoms.

The duration of treatment will vary with the type of lesion and may extend from a few days to several weeks, according to therapeutic response. Relapses, more common in chronic active lesions than in self-limited conditions, usually respond to retreatment.

⛔ Contraindications 71 words ▾

CONTRAINDICATIONS The use of this preparation is contraindicated in the presence of: 1. Acute superficial herpes simplex keratitis. 2.

Fungal diseases of ocular structures. 3. Acute infectious stages of vaccinia, varicella and most other viral diseases of the cornea and conjunctiva.

4. Tuberculosis of the eye. 5.

Hypersensitivity to a component of this medication. The use of this preparation is always contraindicated after uncomplicated removal of a superficial corneal foreign body.

⚠️ Warnings 161 words ▾

WARNINGS NOT FOR INJECTION INTO EYE - FOR TOPICAL USE ONLY Employment of steroid medication in the treatment of herpes simplex keratitis involving the stroma requires great caution; frequent slit-lamp microscopy is mandatory. Prolonged use may result in elevated intraocular pressure and/or glaucoma, damage to the optic nerve, defects in visual acuity and fields of vision, posterior subcapsular cataract formation, or may aid in the establishment of secondary ocular infections from pathogens liberated from ocular tissues.

In those diseases causing thinning of the cornea or sclera, perforation has been known to occur with the use of topical steroids. Acute purulent untreated infection of the eye may be masked or activity enhanced by presence of steroid medication. Viral, bacterial, and fungal infections of the cornea may be exacerbated by the application of steroids.

This drug is not effective in mustard gas keratitis and Sjögren’s keratoconjuncitivitis. If irritation persists or develops, the patient should be advised to discontinue use and consult prescribing physician.

🤒 Adverse Reactions 70 words ▾

ADVERSE REACTIONS Glaucoma with optic nerve damage, visual acuity and field defects, posterior subcapsular cataract formation, secondary ocular infections from pathogens including herpes simplex and fungi, and perforation of the globe. Rarely, filtering blebs have been reported when topical steroids have been used following cataract surgery. Rarely, stinging, or burning may occur.

To report SUSPECTED ADVERSE REACTIONS, contact Bausch & Lomb Incorporated at 1-800-553-5340 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

💬 Information for Patients 17 words ▾

Information for Patients Do not touch dropper tip to any surface as this may contaminate the solution.

⚠️ Precautions 180 words ▾

PRECAUTIONS General As fungal infections of the cornea are particularly prone to develop coincidentally with long-term steroid applications, fungus invasion must be suspected in any persistent corneal ulceration where a steroid has been used or is in use. Intraocular pressure should be checked frequently. Information for Patients Do not touch dropper tip to any surface as this may contaminate the solution.

Usage in Pregnancy Animal reproductive studies have not been conducted with prednisolone sodium phosphate. It is also not known whether prednisolone sodium phosphate can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Prednisolone sodium phosphate should be given to a pregnant woman only if clearly needed.

The effect of prednisolone sodium phosphate on the later growth, development and functional maturation of the child is unknown. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when prednisolone sodium phosphate is administered to a nursing woman.

Pediatric Use Safety and effectiveness in pediatric patients have not been established.

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.
