Ivizia eye drops are generally well tolerated, with only mild, temporary side effects reported by users. However, there’s an important regulatory wrinkle: in July 2025, the FDA issued a warning letter to the manufacturer, Thea Pharma, stating that Ivizia is technically an unapproved new drug. That doesn’t necessarily mean the drops are dangerous, but it does mean the product’s regulatory standing is unsettled.
What’s in Ivizia Eye Drops
Ivizia is marketed as a lubricant eye drop for dry eyes. Its labeled active ingredient is povidone at 0.5%, a standard lubricating compound found in many over-the-counter eye drops. The formula also contains hyaluronic acid and trehalose, two ingredients the manufacturer highlights for their moisturizing and protective properties on the eye’s surface.
One of Ivizia’s main selling points is its preservative-free design. The bottle uses a proprietary filtration system called ABAK, which filters the solution as it’s dispensed so that no chemical preservatives need to be added to the formula. Preservatives like benzalkonium chloride, found in many conventional eye drops, can irritate the eye over time, especially with frequent use. The preservative-free design makes Ivizia a reasonable option for people who use drops multiple times a day or have sensitive eyes.
The FDA Warning Letter
In July 2025, the FDA sent a warning letter to Thea Pharma stating that Ivizia sterile lubricant eye drops are being sold as an unapproved new drug. The issue isn’t that the drops were found to be harmful. Rather, the problem is a regulatory technicality with real consequences: hyaluronic acid and trehalose are not listed as permitted active ingredients for over-the-counter lubricant eye drops under the FDA’s official monograph for ophthalmic products.
For an OTC eye drop to be sold legally without individual FDA approval, it needs to follow the established monograph, which specifies exactly which active ingredients are considered “generally recognized as safe and effective” (GRASE). Because hyaluronic acid and trehalose fall outside that list, the FDA considers Ivizia a new drug that would need its own approval process. The agency also flagged the product as misbranded.
This doesn’t mean the ingredients are proven unsafe. Hyaluronic acid is widely used in eye drops sold internationally, and trehalose has been studied for its ability to protect cells on the surface of the eye from drying out. But without formal FDA approval, the product lacks the level of regulatory review that approved drugs go through. If this matters to you, it’s worth knowing that many other OTC artificial tears on the market do conform to the FDA monograph and don’t carry this issue.
Reported Side Effects
The side effect profile for Ivizia is mild. According to the product’s labeling, you might experience a burning or stinging sensation, a feeling like something is in your eye, or temporary blurred vision shortly after applying the drops. These effects are brief and consistent with what most lubricant eye drops can cause. Mild eye irritation and redness are listed as rare possibilities.
There are no reports of serious adverse effects tied specifically to the formula. If you’ve used other artificial tears without problems, Ivizia is unlikely to cause anything unexpected. People with known sensitivity to any of the listed ingredients should avoid the product, as with any eye drop.
Use With Contact Lenses
Ivizia is labeled as safe for contact lens wearers, which is a direct benefit of the preservative-free formula. To minimize any temporary blurriness, the manufacturer recommends removing your contacts first, applying the drops, and then reinserting your lenses. If you experience irritation or redness while wearing contacts after using the drops, remove the lenses.
Who Should Be Cautious
The product labeling does not include specific age restrictions or warnings for children, pregnant individuals, or nursing parents. That said, the absence of guidance isn’t the same as a green light. For children or anyone with a pre-existing eye condition, it’s reasonable to check with an eye care provider before starting any new drop.
Anyone who has had allergic reactions to povidone, hyaluronic acid, or trehalose should avoid Ivizia. Signs of an allergic reaction would include worsening redness, swelling, or itching that doesn’t resolve after you stop using the drops.
How Ivizia Compares to Standard Artificial Tears
In terms of day-to-day safety, Ivizia behaves like most preservative-free artificial tears. The side effects are similar, the application is the same, and the risk of serious harm is very low. Where it differs is in its regulatory status. Traditional OTC artificial tears that use ingredients like carboxymethylcellulose or polyethylene glycol fit neatly within the FDA’s approved monograph. Ivizia’s inclusion of hyaluronic acid and trehalose puts it in a gray area where it’s widely available but technically non-compliant with U.S. drug regulations.
If you’ve been using Ivizia without problems, the drops aren’t likely to suddenly cause harm. But if you’re choosing a new dry eye product and want the most straightforward regulatory backing, conventional preservative-free artificial tears that stick to monograph-approved ingredients are a simpler bet.
