Steroid Selection Advisor
FML Forte (Fluorometholone) is a synthetic corticosteroid ophthalmic solution formulated at 0.1% concentration. It works by suppressing inflammatory cytokines in the eye, providing rapid relief from postoperative inflammation, allergic conjunctivitis, and uveitis.
TL;DR
- Fluorometholone offers medium‑strength anti‑inflammatory action with a lower risk of intraocular pressure spikes than dexamethasone.
- Loteprednol etabonate is the safest for long‑term use, but it may be less potent for acute post‑surgical swelling.
- Prednisolone acetate is the strongest option, reserved for severe cases where rapid control outweighs IOP risk.
- Choose based on potency, duration, and patient‑specific IOP susceptibility.
Understanding the Core Players
Before diving into the head‑to‑head numbers, it helps to know the key players you’ll encounter when prescribing or buying eye steroids.
Prednisolone acetate is a high‑potency corticosteroid eye drop typically used at 1% concentration. It penetrates the cornea efficiently, making it a first‑line choice for severe uveitis or aggressive post‑operative inflammation.
Dexamethasone ophthalmic is a potent synthetic steroid available in 0.1% or 0.5% formulations. It offers rapid symptom control but carries a moderate risk of raising intraocular pressure (IOP).
Loteprednol etabonate is a soft‑steroid designed to break down quickly in ocular tissue, reducing the chance of steroid‑induced glaucoma. It is usually supplied at 0.5% concentration.
Ocular inflammation refers to the swelling, redness, and pain that occur after eye surgery, trauma, or allergic exposure. Managing it promptly prevents scarring and vision loss.
Intraocular pressure (IOP) elevation is a common side effect of topical steroids, potentially leading to steroid‑induced glaucoma if left unchecked.
Steroid‑induced glaucoma develops when chronic steroid use raises IOP beyond safe limits, damaging the optic nerve over time.
How Fluorometholone Stacks Up
Fluorometholone sits in the middle of the potency curve. Its anti‑inflammatory strength is roughly comparable to dexamethasone, yet it has a more favorable safety profile for patients with borderline IOP.
Key attributes:
- Potency: Medium‑high (≈80% of dexamethasone)
- Onset: 30-45minutes for noticeable symptom relief
- Duration: 12hours per dose; typically dosed 4times daily
- IOP risk: Low‑to‑moderate; studies show ≈10% of users develop ≥5mmHg rise after 2weeks
- Preferred use: Post‑operative inflammation, mild‑to‑moderate allergic conjunctivitis, short‑term uveitis control
Quick‑Reference Comparison Table
| Drug | Relative Potency* | Typical Concentration | Duration of Action | IOP Elevation Risk | Best‑Fit Indications |
|---|---|---|---|---|---|
| Fluorometholone (FML Forte) | 0.8 | 0.1% | ~12h | Low‑to‑moderate | Post‑op, mild‑moderate allergy, short‑term uveitis |
| Prednisolone acetate | 1.0 (reference) | 1% | ~8h | High | Severe uveitis, aggressive post‑op swelling |
| Dexamethasone ophthalmic | 0.9 | 0.1% / 0.5% | ~10h | Moderate | Acute inflammation, corneal graft rejection prophylaxis |
| Loteprednol etabonate | 0.6 | 0.5% | ~12h | Very low | Long‑term therapy, steroid‑responsive allergic conjunctivitis |

When to Choose Fluorometholone Over the Rest
Consider these three real‑world scenarios:
- Routine cataract extraction: Patients usually need a short burst of anti‑inflammation. Fluorometholone’s 12‑hour coverage and modest IOP impact make it a safe default.
- Allergic conjunctivitis in a glaucoma suspect: Loteprednol would be ideal for chronic use, but for a flare‑up lasting a week, fluorometholone offers stronger relief without the same IOP vigilance required for dexamethasone.
- Severe anterior uveitis with rapid vision loss: Here, prednisolone acetate’s higher potency outweighs its IOP risk; you’d start with prednisolone, then taper to fluorometholone once inflammation subsides.
Safety Checklist for Clinicians
Regardless of the choice, keep this quick safety checklist handy:
- Baseline IOP measurement before the first steroid drop.
- Re‑measure IOP after 1week for medium‑potency agents (fluorometholone, dexamethasone).
- Consider a steroid‑sparing regimen (e.g., NSAID eye drops) for patients with a history of steroid response.
- Educate patients to report new eye pain, halos, or blurred vision-possible signs of rising IOP.
Cost and Accessibility Overview
Cost can influence adherence. Generally, generic fluorometholone drops are priced between $15-$25 for a 5‑ml bottle in the U.S., comparable to generic prednisolone acetate but cheaper than brand‑name dexamethasone (often $30-$45). Loteprednol etabonate, being a newer soft‑steroid, commands a premium of $35-$50.
Related Concepts Worth Exploring
To deepen your understanding, you might also read about:
- Non‑steroidal anti‑inflammatory eye drops (NSAIDs) such as ketorolac, which can be combined with low‑potency steroids for synergistic effect.
- Topical antibiotic prophylaxis post‑surgery, especially when steroids suppress local immunity.
- Eye‑drop preservative toxicity-preservative‑free formulations reduce risk of corneal epitheliopathy.
Choosing the Right Steroid: A Decision Tree
Use this quick flowchart to land on the most appropriate eye steroid:
- Is the inflammation severe (e.g., >2+ cells in anterior chamber)?
- Yes → Prednisolone acetate.
- No → Go to step 2.
- Is the patient a known steroid responder or has glaucoma?
- Yes → Loteprednol etabonate.
- No → Go to step 3.
- Do you need a balance of potency and safety for short‑term use?
- Yes → Fluorometholone (FML Forte).
- No → Dexamethasone for rapid, high‑potency control.
Bottom Line
If you need a middle‑ground steroid that offers solid anti‑inflammatory action without a steep IOP climb, Fluorometholone is a sensible pick. Reserve stronger agents for aggressive disease and softer agents for chronic, low‑grade inflammation or patients at high glaucoma risk.
Frequently Asked Questions
What is the typical dosage schedule for FML Forte?
Most ophthalmologists prescribe one drop in the affected eye(s) four times daily for the first 3‑5days, then taper to twice daily over the next week, depending on clinical response.
How quickly does Fluorometholone lower intra‑ocular pressure?
Fluorometholone itself rarely lowers IOP; instead, it can cause a modest rise. In steroid‑responsive patients, pressure may increase within 1‑2weeks of regular use. Monitoring should start after the first week.
Can I use Fluorometholone with other eye drops?
Yes. It can be administered alongside preservative‑free artificial tears, topical antibiotics, or NSAID drops. Wait at least 5minutes between applications to avoid dilution.
Is Fluorometholone safe for children?
Pediatric use is allowed but at a reduced frequency-typically twice daily. Children are more prone to steroid‑induced IOP spikes, so regular pressure checks are essential.
How does Loteprednol compare cost‑wise to Fluorometholone?
Loteprednol etabonate usually costs $35‑$50 per 5‑ml bottle, whereas generic Fluorometholone ranges $15‑$25. The price gap reflects the newer soft‑steroid chemistry and brand‑name positioning.
What are signs of steroid‑induced glaucoma I should watch for?
Patients may report blurred vision, peripheral vision loss, or halos around lights. An IOP reading above 22mmHg or a sudden rise of ≥5mmHg from baseline warrants immediate discontinuation and ophthalmology referral.
