When it comes to treating eye inflammation, Fluorometholone is a synthetic corticosteroid eye drop marketed as FML Forte, designed to reduce swelling and redness with relatively low intra‑ocular pressure side effects. It’s often prescribed after cataract surgery or for allergic conjunctivitis where a moderate‑strength steroid is needed.
Key Takeaways
- Fluorometholone offers medium potency with a good safety profile for most post‑surgical eye inflammation.
- Stronger steroids like dexamethasone work faster but raise the risk of pressure spikes.
- Non‑steroidal drops such as ketorolac can control pain without steroid‑related side effects.
- Cost, prescription requirements and duration of therapy differ markedly across options.
- Choosing the right drop depends on inflammation severity, patient eye pressure history, and how long treatment is needed.
What Is Fluorometholone (FML Forte)?
Fluorometholone belongs to the class of corticosteroids that suppress immune activity in the eye. The typical concentration in FML Forte is 0.1% (1mg/mL), packaged in single‑use vials. Its molecular weight is 438.5g/mol, and it has a half‑life of about 4hours on the ocular surface, allowing 4‑6 times daily dosing for most patients.
Because it exerts a milder pressure‑elevating effect than other steroids, ophthalmologists often prefer it for patients with a history of glaucoma or ocular hypertension.
How Steroid Eye Drops Work
All steroid eye drops bind to glucocorticoid receptors in ocular tissues, reducing the production of inflammatory cytokines. This leads to less swelling, fewer leukocytes, and quicker recovery. However, the same pathway can also impair trabecular meshwork function, raising intra‑ocular pressure (IOP) in susceptible individuals.
Criteria for Comparing Eye Drops
When you line up Fluorometholone against alternatives, focus on these six factors:
- Potency - how quickly it calms inflammation.
- Side‑effect profile - especially IOP rise, cataract formation, and allergic reactions.
- Duration of therapy - typical course length and tapering needs.
- Prescription status - NHS‑prescribed, over‑the‑counter (OTC), or specialist‑only.
- Cost - average price in the UK market.
- Typical indications - post‑surgical inflammation, allergic conjunctivitis, uveitis, etc.
Alternative Steroid and Non‑Steroid Options
Below are the most common drops that patients compare with Fluorometholone:
- Prednisolone acetate - a high‑potency steroid (1% concentration) often used for severe uveitis.
- Dexamethasone - a very strong steroid (0.1% or 0.05% formulations) with rapid action but higher IOP risk.
- Loteprednol etabonate - a “soft” steroid designed to break down quickly, reducing pressure spikes.
- Difluprednate - an ultra‑potent steroid (0.05%) used for aggressive post‑operative inflammation.
- Hydrocortisone - low‑potency steroid (0.5%) mainly for mild irritation.
- Ketorolac - a non‑steroidal anti‑inflammatory drug (NSAID) eye drop (0.5%) that controls pain without steroid‑related pressure issues.

When Fluorometholone Is the Right Choice
If you need a steroid that balances efficacy with a lower risk of triggering glaucoma, Fluorometholone is often the go‑to. It works well for:
- Patients with mild‑to‑moderate post‑cataract surgery inflammation.
- Individuals with a known tendency for IOP spikes when using stronger steroids.
- Those who require a short‑term course (usually 1‑2 weeks) without a complicated taper.
Because the drug is less likely to cause cataract formation compared with high‑potency agents, it’s also a safe option for patients who have already undergone lens replacement.
Scenarios Where Another Drop Might Beat Fluorometholone
Stronger inflammation or underlying conditions sometimes demand a more aggressive approach. Here’s when you’d reach for an alternative:
- Dexamethasone - when rapid control is essential, such as in corneal graft rejection.
- Loteprednol etabonate - for patients who need medium‑potency but have a very sensitive pressure response.
- Difluprednate - for refractory uveitis where lower‑potency steroids have failed.
- Ketorolac - when pain relief is the primary goal and steroid side effects are undesirable.
Practical Tips for Using Steroid Eye Drops
Regardless of the product, follow these habits to maximise benefit and minimise risk:
- Wash hands thoroughly before each drop.
- Pull down the lower eyelid and place the drop without touching the tip to the eye.
- Close the eye gently for 1-2 minutes; apply gentle pressure on the inner corner to limit systemic absorption.
- Schedule IOP checks if you’re on steroids for more than two weeks, especially if you have glaucoma risk factors.
- Never share eye drops; contamination can cause serious infection.
Cost Considerations in the UK
Most NHS prescriptions for Fluorometholone carry a standard £8.60 prescription charge (or free with exemption). Private purchase can range from £12‑£15 per 5‑ml bottle. By contrast, premium drops like Loteprednol etabonate or Difluprednate can exceed £25‑£35, often requiring a specialist’s prescription.
How to Decide Which Drop Fits Your Needs
Use the decision tree below to narrow down the optimal choice:
- Is the inflammation mild‑to‑moderate?
Yes → Consider Fluorometholone or Loteprednol.
No → Move to step2. - Do you have a history of glaucoma or elevated IOP?
Yes → Prefer Fluorometholone or Loteprednol; avoid Dexamethasone and Difluprednate.
No → Stronger steroids become viable. - Is rapid anti‑inflammatory action critical (e.g., graft rejection)?
Yes → Dexamethasone or Difluprednate. - Is pain the main complaint rather than redness/swelling?
Yes → Ketorolac (NSAID) may be sufficient.
Always discuss the plan with your ophthalmologist; they can tailor the regimen to your specific eye health profile.
Frequently Asked Questions
Can I use Fluorometholone without a prescription?
In the UK, Fluorometholone is prescription‑only. You’ll need a valid NHS or private prescription from an eye‑care professional.
How quickly does Fluorometholone start working?
Patients typically notice reduced redness and swelling within 24‑48hours, though full effect may take up to a week of regular dosing.
What are the main side effects to watch for?
The most common concerns are a slight rise in intra‑ocular pressure, delayed wound healing, and rare allergic reactions on the ocular surface.
Can I switch from Fluorometholone to a stronger steroid if needed?
Yes, but the switch should be guided by your doctor. They’ll monitor IOP closely during the transition.
Is it safe to use Fluorometholone after cataract surgery?
It’s one of the most commonly prescribed drops for post‑cataract inflammation because it balances potency with a low risk of pressure spikes.
Bottom Line
Fluorometholone (FMLForte) sits comfortably in the middle of the steroid eye‑drop spectrum: strong enough to calm most post‑operative inflammation, yet gentle enough for patients prone to pressure spikes. If you need faster action or are dealing with severe uveitis, look to higher‑potency options like dexamethasone or difluprednate, keeping in mind the higher side‑effect burden. For pain‑only scenarios, an NSAID such as ketorolac may spare you from steroids altogether. Always let an eye‑care professional weigh these factors against your personal eye history and budget.

October 9, 2025 AT 14:44The pharmacokinetic profile of Fluorometholone is quite intriguing, especially when you consider its 0.1% concentration and the resultant ocular surface half‑life of roughly four hours. Its mechanism of action hinges on glucocorticoid receptor agonism, which down‑regulates NF‑κB mediated cytokine cascades and thereby attenuates leukocyte infiltration. In terms of intra‑ocular pressure dynamics, it presents a low‑to‑moderate risk, a characteristic that makes it a compelling option for patients with a predisposition to glaucoma. Moreover, the molecular weight of 438.5 g/mol facilitates decent corneal penetration without excessive systemic absorption, a balance that is often missed by higher potency agents. The cost‑effectiveness ratio, roughly £12‑£15 per pack in the UK, further bolsters its utility in resource‑constrained settings. Clinical guidelines suggest a dosing frequency of four to six times daily for post‑operative inflammation, which aligns well with patient adherence patterns observed in most ophthalmology practices. While the drug is prescription‑only, its safety profile permits a relatively short tapering schedule, typically spanning one to two weeks, thereby reducing the burden of long‑term steroid exposure. From a formulary standpoint, the single‑use vials mitigate contamination risk, an important consideration given the delicate ocular environment. Comparative data indicate that its IOP elevation potential is less than that of prednisolone acetate, yet it remains more potent than hydrocortisone, positioning it neatly in the middle of the potency spectrum. The anti‑inflammatory efficacy, measured by reduction in conjunctival hyperemia and aqueous flare, usually becomes apparent within 24‑48 hours, offering patients quick symptomatic relief. It is also worth noting that the drug’s metabolite profile does not favor cataractogenesis, an added advantage for post‑cataract surgery patients. In summary, Fluorometholone strikes a pragmatic balance between efficacy, safety, and affordability, making it a versatile tool in the ophthalmologist’s armamentarium.
However, clinicians must remain vigilant for subtle IOP rises, especially in steroid responders, and schedule follow‑up tonometry accordingly.
Lastly, patient education on proper instillation technique cannot be overstated, as improper application can lead to suboptimal outcomes.
