How to Store and Use Autologous Serum Eye Drops Correctly

Autologous serum eye drops are a unique medication that requires different storage and handling than most eye drops. Because they are made from biological material — your own blood serum — they must be kept frozen to preserve their biological activity. Proper handling is essential both for safety and effectiveness.

Kearney Park Pharmacy provides complete storage and usage instructions with every order. This article covers the key points to help patients understand and follow the requirements.

Frozen Storage: The Primary Requirement

All bottles of autologous serum eye drops that you are not currently using must be kept frozen in the freezer — ideally at or below 0°F (-18°C), which is standard household freezer temperature. Freezing preserves the biological components and prevents microbial growth, extending the usable life of your drops significantly. Per USP guidelines and your specific beyond-use date, frozen autologous serum drops are generally stable for 3-6 months.

Store your frozen bottles in a clean, sealed bag or container in the freezer, away from the door where temperature fluctuations are greatest. Keep them organized with the preparation date visible so you use the oldest bottles first.

Thawing a Bottle for Current Use

When you are ready to start a new bottle, remove it from the freezer and allow it to thaw at room temperature or in the refrigerator. Do not microwave or heat the bottle to speed thawing — this can damage the biological components. Once thawed, store the current-use bottle in the refrigerator. The thawed bottle should be used within 7-14 days, per the instructions on your label.

Before each use, gently roll the bottle between your palms to mix if any separation has occurred. Inspect the drops — they should be clear and colorless or very faintly yellow. If you notice any cloudiness, floating particles, or unusual color, do not use that bottle. Call Kearney Park Pharmacy at 972-329-1168.

How to Apply Autologous Serum Drops

Your prescribing provider will give you specific dosing instructions — typically a certain number of drops per eye at specific intervals. Wash your hands thoroughly before handling the bottle. Tilt your head back, look up, and gently pull the lower eyelid down to create a small pocket. Apply the prescribed number of drops without touching the bottle tip to the eye or any surface. Gently close the eye and apply light pressure to the inner corner of the eye for 1-2 minutes to reduce drainage.

Wait at least 5 minutes between applying different eye medications, and follow your provider's specific instructions about the order of application if you use multiple drops. Do not rinse the eye after applying serum drops unless specifically directed.

When to Call the Pharmacy or Your Provider

Call Kearney Park Pharmacy if you have concerns about your drops' appearance, if you experience unexpected irritation or changes in vision after starting serum therapy, if a bottle was left out or thawed and you are uncertain about its safety, or if you are running low and need to coordinate the next blood draw and preparation cycle.

Call your eye care provider if your symptoms are not improving, if you develop redness, pain, or increased discharge, or if you have any concerns about your ocular health. Your provider manages the clinical side; we manage the pharmacy side. Together, we support the best possible outcome for you.

Frequently Asked Questions

What happens if I accidentally leave a frozen bottle out overnight?

If a frozen bottle thaws unintentionally at room temperature overnight, it may still be usable depending on conditions. Contact Kearney Park Pharmacy at 972-329-1168 to discuss. Do not refreeze a bottle that has fully thawed — refreeze/thaw cycles can degrade the biological components. Treat it as a thawed bottle and use it within 7-14 days or discard if there is any uncertainty.

Can I travel with autologous serum tears?

Yes, with planning. Use a small insulated travel cooler with ice packs for short trips. For longer travel, bring enough frozen bottles in a portable cooler. For air travel, the frozen bottles can go in your checked luggage with dry ice or in your carry-on with a small ice pack (check TSA liquid rules for carry-on). Your prescription label should be kept with the bottles. Call 972-329-1168 for travel-specific advice.

How do I order my next batch of autologous serum drops?

Contact Kearney Park Pharmacy at 972-329-1168 at least 2-3 weeks before your current supply runs out. We will coordinate with your provider's office to schedule the next blood draw and begin the preparation process. Planning ahead is important because the preparation takes time. Do not wait until you run out.

Shipping Autologous Serum Eye Drops Across Texas: How We Keep Them Safe

By Park • June 5, 2026

Shipping Autologous Serum Eye Drops Across Texas: How We Keep Them Safe One of the most common concerns patients and providers have about autologous serum tears is whether they can be shipped safely without losing their biological effectiveness. The answer is yes — with appropriate frozen shipping methods, autologous serum tears can be shipped anywhere in Texas while maintaining the cold chain required to preserve their biological activity. Kearney Park Pharmacy has the shipping expertise to ensure your autologous serum drops arrive frozen and intact. Here is how we do it. Why Frozen Shipping Is Required The growth factors, vitamins, and proteins that make autologous serum tears therapeutically effective are biological molecules. Like all proteins, they are susceptible to degradation — both from microbial activity and from the temperature-sensitive conformational changes that can occur at warmer temperatures over time. Freezing essentially 'pauses' biological activity, preserving the components in their active state until the drops are thawed for use. Shipping at refrigerated (not frozen) temperatures alone is insufficient for the extended stability required across transit times. Frozen shipping maintains the drops in the same state they were in when they left our pharmacy — safe, sterile, and biologically potent. Our Shipping Method: Dry Ice and Insulated Containers Kearney Park Pharmacy ships autologous serum tears in insulated containers with dry ice to maintain a frozen state throughout transit. Dry ice maintains temperatures well below freezing, ensuring the drops remain frozen even if transit takes 24-48 hours. We carefully calculate the amount of dry ice needed based on the transit time to your location in Texas. Each shipment is packaged to minimize the risk of the insulated container being compromised during handling. We use appropriate outer packaging to contain the dry ice safely and label shipments clearly with handling instructions. We track every shipment and can provide updates on delivery status. What to Do When Your Shipment Arrives When your autologous serum drops arrive, handle the dry ice carefully — do not touch it directly with bare hands (use gloves or a cloth). Remove the bottles from the dry ice packaging and transfer them promptly to your freezer. Do not leave them at room temperature — even if they are still frozen when they arrive, unnecessary warming shortens their remaining shelf life. Inspect the packages for any damage. Each bottle should be sealed with no signs of leaking. If any bottle appears damaged or shows signs of having thawed and refrozen (ice crystals on the outside, unusual appearance of the liquid inside), contact Kearney Park Pharmacy immediately at 972-329-1168 before using that bottle. Coordinating Delivery for Your Schedule We work with you to schedule shipping on days that ensure prompt delivery and that you will be available to receive and refrigerate the package. We typically do not ship late in the week to avoid packages sitting in carrier facilities over a weekend. For patients who know they will be away, we coordinate shipping for when they return. If you have specific delivery concerns — a location that is difficult for carriers to access, a need for a specific delivery day, or questions about shipping to a remote Texas location — call us at 972-329-1168 before your next order. We will work out the best plan for your situation. Frequently Asked Questions What if I'm not home when the shipment arrives? For frozen shipments with dry ice, a several-hour window of maintained temperature is typical even after delivery. However, prompt retrieval is important. If you know you won't be home, consider having a neighbor receive the package, asking the carrier to leave it in a shaded location, or scheduling delivery for a day when someone will be present. Call 972-329-1168 if you have specific concerns. Can you ship autologous serum tears to rural parts of Texas? Yes. We ship throughout Texas including rural areas. Shipping times to rural locations may be slightly longer, which we account for in our dry ice quantity. We have shipped to communities in all regions of Texas. Call 972-329-1168 to confirm shipping to your specific location and discuss the expected transit time. How much does shipping cost for autologous serum tears? Shipping costs for frozen products with dry ice are higher than standard shipping due to the special packaging required. Contact Kearney Park Pharmacy at 972-329-1168 for current shipping fee information specific to your location and order size. We are transparent about all costs before your order ships.

What Texas Eye Doctors Need to Know About Prescribing Autologous Serum Tears

By Park • June 5, 2026

What Texas Eye Doctors Need to Know About Prescribing Autologous Serum Tears For ophthalmologists and optometrists in Texas who want to incorporate autologous serum tears into their treatment protocols for severe OSD patients, having a reliable compounding pharmacy partner that manages the process smoothly is essential. The preparation is more complex than a standard compounding order, and the logistics require clear communication between provider, patient, and pharmacy. Kearney Park Pharmacy in Mesquite, Texas, handles the autologous serum tear preparation process end-to-end and ships to patients statewide. Here is what providers need to know. Writing the Prescription: What to Include A complete autologous serum tear prescription should include: patient name and DOB, 'autologous serum ophthalmic solution,' concentration (20% or 50%), quantity (number of bottles and volume per bottle — typically 5mL bottles), dosing instructions (drops per eye and frequency), number of refills, and your complete prescriber information. Note any special instructions about packaging (e.g., single-dose units if preferred). Contact Kearney Park Pharmacy before the first prescription to coordinate the blood draw logistics. We will provide your office with instructions for blood collection, appropriate tube types, and shipping requirements for the sample. This pre-prescription coordination ensures the process goes smoothly. Blood Collection and Shipping to Our Pharmacy The blood draw can be performed in your office, at a phlebotomy lab, or at another collection site, depending on your practice setup. We provide collection instructions specifying the tube type, volume needed, and how to handle and ship the sample. Generally, the whole blood is shipped overnight to us on ice (not frozen). We process it upon arrival. If you prefer to have a lab process the serum before shipping, we can work with that arrangement as well. The key requirement is that the serum arrives at our pharmacy under conditions that preserve its quality. Our team is experienced in coordinating these logistics and will guide your staff through the process. Patient Selection and Setting Expectations Autologous serum tears work best for patients with clear biological rationale — Sjogren's, GVHD, neurotrophic keratitis, persistent epithelial defects, SJS. For patients with less severe or more typical dry eye, the benefit-to-complexity ratio may not favor serum tears, and conventional treatments should be optimized first. Setting appropriate patient expectations is also important. Not all patients see immediate dramatic improvement. The biological support provided by serum tears promotes healing over time, and patients should be counseled to continue therapy consistently and monitor outcomes at follow-up. Insurance prior authorization may be required and should be initiated early in the process. Ongoing Management and Refill Coordination For patients on ongoing autologous serum therapy, repeat blood draws are needed periodically. We recommend planning refill cycles in advance so patients don't run out of their supply. Kearney Park Pharmacy proactively contacts established patients about their supply levels and helps coordinate timing. For providers with multiple OSD patients on serum therapy, we can manage the coordination for all of them. We appreciate and value our provider relationships. Our goal is to handle the pharmacy logistics so thoroughly that your involvement after the initial prescription is minimal — just the ongoing clinical monitoring that belongs with your expertise. Frequently Asked Questions Does Kearney Park Pharmacy accept autologous serum prescriptions from outside the DFW area? Absolutely. We serve eye care providers and patients throughout Texas. The blood draw can be coordinated locally for the patient (at a lab near them) and shipped to us. We then ship the finished drops back to the patient anywhere in Texas. Geography is not a barrier. What documentation do you provide for provider records? We can provide information about the preparation process, beyond-use dating approach, and storage requirements upon request. Providers who want documentation of our compounding standards for quality assurance purposes can contact us at 972-329-1168. Can you help with prior authorization documentation for autologous serum tears? Yes, to the extent possible. We can provide pharmacy-related documentation (preparation details, product information) that may support a prior authorization request. The clinical documentation (diagnosis, prior treatment failure, clinical necessity) should come from your office. Call 972-329-1168 to discuss what we can provide. READY TO ORDER?

Ocular Surface Disease and the Role of Autologous Serum Tears

By Park • June 4, 2026

Ocular Surface Disease and the Role of Autologous Serum Tears Ocular surface disease (OSD) is an umbrella term encompassing a range of conditions that affect the health and function of the eye's surface — the cornea, conjunctiva, and tear film. It is one of the most common reasons patients see an eye doctor and one of the most impactful in terms of quality of life. Severe OSD can cause constant discomfort, reduced vision, and significant functional limitations. For patients with severe or refractory OSD, autologous serum tears represent one of the most biologically meaningful therapeutic options available. Here is how they fit into the management of OSD. What Is Ocular Surface Disease? The ocular surface includes the corneal and conjunctival epithelium, the tear film, the meibomian glands (which produce the lipid layer of tears), the lacrimal glands (which produce the aqueous layer), and the goblet cells (which produce mucins). Disease affecting any of these components can cause the constellation of symptoms that patients describe as dry eye, burning, gritty sensation, light sensitivity, and blurred vision. OSD can range from mild evaporative dry eye (very common, often managed with over-the-counter artificial tears and warm compresses) to severe aqueous-deficient dry eye (as seen in Sjogren's syndrome) or severe inflammatory and destructive surface disease (as in GVHD, SJS, or neurotrophic keratitis). The more severe end of this spectrum is where autologous serum tears are most clinically relevant. How Autologous Serum Addresses the Biological Deficit In severe OSD, the tear film is not just insufficient in volume — it lacks the biological components needed to sustain healthy surface cells. The surface epithelium, deprived of growth factors, vitamins, and structural proteins, becomes unstable, inflamed, and prone to breakdown. This is not a problem that more lubricant can fix. Autologous serum tears introduce the biological components that the compromised tear film cannot provide. EGF and other growth factors stimulate epithelial cell proliferation and migration — essential for healing the surface. Fibronectin supports cell attachment. Vitamin A normalizes epithelial differentiation. The result, in patients who respond to therapy, is a surface that heals and stabilizes rather than one that continues to break down. Integration with Other OSD Treatments Autologous serum tears are not used in isolation — they are part of a comprehensive OSD management plan. Patients typically continue other appropriate treatments alongside serum drops: anti-inflammatory drops (cyclosporine, lifitegrast), meibomian gland treatments if applicable, punctal plugs if appropriate, and other supportive measures. Serum tears provide the biological support component that other treatments do not. Your ophthalmologist will design a treatment plan that addresses all components of your OSD. Autologous serum tears fit into that plan as one element, typically prescribed when the surface disease is severe enough to require their biological support in addition to standard therapies. Getting Access to Autologous Serum Tears in Texas For Texas patients with severe OSD, access to autologous serum tears requires a prescription from an eye care provider and a compounding pharmacy capable of preparing them properly. Kearney Park Pharmacy is a licensed sterile compounding pharmacy in Mesquite, Texas, that coordinates the full process — from blood draw logistics to sterile preparation to statewide shipping. We work with ophthalmologists, optometrists, and cornea specialists across Texas to serve their patients with severe OSD. If your provider has prescribed autologous serum tears or is considering doing so, call us at 972-329-1168 or ask them to contact us directly. Frequently Asked Questions How often do I apply autologous serum drops for OSD? Dosing varies by condition and severity. Common regimens range from 4 to 8 times daily, and some protocols use them hourly in acute situations. Your prescribing provider will specify the exact dosing on your prescription. Always follow your provider's instructions. What if my OSD has not improved after several months of serum tears? Report this to your eye care provider. They will reassess your condition, evaluate whether your diagnosis is accurate, consider adjusting the concentration or frequency, or explore additional or alternative treatments. Autologous serum tears are highly effective for many patients but not a universal solution for all forms of OSD. Does Kearney Park Pharmacy work with cornea specialists? Yes. We work with cornea specialists and general ophthalmologists across Texas who prescribe autologous serum tears. If you are a cornea specialist and want to establish a referral relationship with us, call 972-329-1168.
