Pred Forte is a prescription eye drop containing 1% prednisolone acetate, a steroid that reduces inflammation inside and around the eye. It comes as a milky-white suspension and is one of the most commonly prescribed ophthalmic steroids, used after eye surgery, during flare-ups of eye inflammation, and for certain allergic eye conditions.
How Pred Forte Works
Prednisolone acetate belongs to a class of drugs called glucocorticoids. When applied to the eye, it blocks the release of a fatty acid called arachidonic acid from cell membranes. That acid is the raw material your body uses to produce prostaglandins and leukotrienes, two chemical signals that drive inflammation. By cutting off the supply, Pred Forte reduces swelling, redness, pain, and the migration of immune cells into damaged tissue.
This broad suppression of the inflammatory response is what makes it effective, but it also means the drops can slow healing. That tradeoff is why Pred Forte is used under close supervision, typically with scheduled follow-up appointments so your eye doctor can monitor how the eye is responding.
What It’s Prescribed For
Pred Forte is approved to treat steroid-responsive inflammation of the eye. In practice, the most common reasons you’ll be given a bottle include:
- Uveitis: inflammation of the middle layer of the eye, which can cause pain, light sensitivity, and blurred vision
- Post-surgical inflammation: routine use after cataract surgery, corneal procedures, or other eye operations to keep swelling in check
- Keratitis: inflammation of the cornea from injury or immune reactions
- Allergic conjunctivitis: severe allergic inflammation that hasn’t responded to non-steroidal treatments
It is not an antibiotic and does not treat infections. In fact, using it during certain infections can make things significantly worse.
When It Should Not Be Used
Pred Forte is contraindicated in several types of eye infections. These include most viral diseases of the cornea and conjunctiva, particularly herpes simplex keratitis (the branching “dendritic” ulcer pattern), chickenpox-related eye disease, and vaccinia. It’s also off-limits for fungal infections of the eye and mycobacterial infections like ocular tuberculosis. Using a steroid drop in any of these situations suppresses the immune response the eye needs to fight off the infection, potentially leading to rapid, sight-threatening damage.
Acute bacterial infections with visible pus (purulent infections) that haven’t been treated with antibiotics are also a contraindication. If you have an active eye infection and aren’t sure of the cause, your doctor will typically identify or rule out these conditions before starting steroid drops.
How to Use It
Because Pred Forte is a suspension rather than a solution, the active ingredient settles to the bottom of the bottle. Shaking it well before each use is essential. If you skip this step, the first drops out of the bottle may contain very little medication, while the last drops contain a concentrated dose. Neither scenario gives you the therapeutic effect your doctor intended.
Dosing frequency varies depending on what’s being treated and how severe the inflammation is. For acute conditions, your doctor may start you on drops every one to two hours, then gradually space them out as symptoms improve. For milder or chronic inflammation, you might use them two to four times daily. The key point is to follow the schedule you’re given closely, because both overuse and underuse carry real risks.
Why You Taper Instead of Stopping
One of the most important things to understand about Pred Forte is that you should not stop it abruptly. Your doctor will typically prescribe a tapering schedule, reducing the number of daily drops over days or weeks. There are two reasons for this.
First, suddenly removing the anti-inflammatory effect can cause the original inflammation to rebound, sometimes worse than it was initially. Second, even with eye drops, some steroid is absorbed systemically. If you’ve been using the drops frequently for more than a couple of weeks, a gradual reduction gives your body time to readjust. The length of a taper depends on how long you’ve been on the drops and how your eye is healing, ranging from about a week to several weeks.
Risks of Prolonged Use
Steroid eye drops are powerful tools, but they come with well-documented side effects when used for extended periods. The two most significant are elevated eye pressure and cataract formation.
Prolonged use of Pred Forte can raise intraocular pressure, the fluid pressure inside the eye. In some people, this happens within just a few weeks. If the pressure stays elevated, it can damage the optic nerve, a condition called steroid-induced glaucoma. This is why your eye doctor will check your pressure at follow-up visits during treatment. Some people are genetically more susceptible to pressure spikes from steroids, and there’s no reliable way to predict who will respond this way before starting the medication.
Long-term steroid use in the eye can also accelerate the formation of cataracts, specifically a type called posterior subcapsular cataracts. These tend to develop gradually and affect central vision more than other cataract types. The risk increases with both the duration and frequency of steroid use, which is another reason doctors aim to use the lowest effective dose for the shortest necessary time.
Other possible side effects include a stinging or burning sensation on application, temporary blurry vision after instilling the drops, and in rare cases, thinning of the cornea or sclera with very prolonged use.
Brand vs. Generic Availability
For years, Pred Forte was available only as the brand-name product, which made it relatively expensive. The FDA has now approved generic versions of prednisolone acetate 1% ophthalmic suspension, with manufacturers including Lupin (approved August 2024) and Amneal (approved June 2025). Generic versions typically start around $25 for a 5 mL bottle, though prices vary by pharmacy and insurance coverage.
If your prescription is written for the brand name, ask your pharmacist whether a generic substitution is available and appropriate. The active ingredient and concentration are the same, though inactive ingredients in the suspension may differ slightly between manufacturers.
