What is Rocklatan?

Rocklatan is a prescription ophthalmic solution specifically developed to lower intraocular pressure (IOP) in adults. It was approved by the U.S. Food and Drug Administration (FDA) to address two major eye conditions where eye pressure is a concern:

• Open-angle glaucoma – A chronic condition in which the eye’s drainage canals become less efficient, causing a gradual buildup of pressure. Left untreated, this can damage the optic nerve and lead to irreversible vision loss.
• Ocular hypertension – A situation where eye pressure is consistently higher than normal, even without signs of optic nerve damage or vision loss. Without careful monitoring, this condition can progress to glaucoma.

What makes Rocklatan different from many single-ingredient eye drops is its dual-action formula. Each bottle contains two active ingredients:

1. Netarsudil – Belongs to a class called rho kinase inhibitors. It works by improving fluid drainage from the eye and reducing fluid production.
2. Latanoprost – A prostaglandin analog that also increases the outflow of fluid from the eye but through a different pathway.

By targeting multiple mechanisms at once, Rocklatan can often reduce eye pressure more effectively than using either ingredient alone.

Currently, there is no generic version of Rocklatan available, which means patients must use the brand-name medication as prescribed.

Forms and Strengths of Rocklatan

Rocklatan comes in a sterile eye drop solution, designed for direct application to the affected eye or eyes. The formulation is standardized so every drop delivers the same therapeutic amount of medication.

• Available strength: 0.02% / 0.005%
  • This means each milliliter of solution contains:
    • 0.2 mg of netarsudil
    • 0.05 mg of latanoprost

The concentration is carefully balanced to ensure optimal results with minimal dosing frequency. Since the dose is standardized, your doctor’s main adjustment will usually be whether you use it in one eye or both, not the strength of the medication itself.

Because Rocklatan is a prescription medication, your pharmacy will supply it in a small, light-protected bottle with a dropper tip. This packaging helps maintain sterility and protect the active ingredients from breakdown.

Rocklatan Dosage Instructions

For most adults with open-angle glaucoma or ocular hypertension, the recommended Rocklatan dosage is:

• One drop in the affected eye(s) once daily in the evening.

The evening dosing is important—latanoprost (one of Rocklatan’s components) works best overnight, and nighttime application can help reduce side effects like blurred vision during the day.

Step-by-Step Application Instructions

1. Wash your hands thoroughly – Use soap and water before touching the bottle or your eye area to prevent contamination.
2. Get into position – Tilt your head back slightly and gently pull your lower eyelid down to create a small pocket.
3. Hold the bottle correctly – Position the dropper tip directly above the pocket without touching your eye, lashes, or skin.
4. Apply the medication – Squeeze one single drop into the lower eyelid pocket.
5. Close and press – Close your eye gently and press a finger against the inner corner (near your nose) for 1–2 minutes. This helps keep the drop in your eye rather than draining into your tear duct.
6. Avoid contamination – Never let the dropper tip touch your eye or any surface.
7. Contact lens users – Remove soft lenses before application and wait at least 15 minutes before putting them back in.

Important Guidelines

• Use Rocklatan at the same time every evening for consistent pressure control.
• If you miss a dose, skip it and resume your normal schedule the next day—do not double up.
• Wait at least 5 minutes before applying any other eye medications to avoid washing out the drug.
• Use only the dose your doctor prescribed—more is not better and can increase side effects.

Rocklatan is generally intended as a long-term treatment. Most patients will need to use it daily to keep their eye pressure under control, with periodic check-ups to monitor effectiveness.

Potential Side Effects of Rocklatan

Like all medications, Rocklatan can cause side effects—although many people tolerate it well. Knowing what to expect helps you distinguish between normal temporary reactions and symptoms that require medical attention.

Common Side Effects

These often improve over time as your eyes adjust:

• Redness or mild irritation in the eyes
• Eye discomfort or mild burning sensation
• Blurred vision shortly after applying drops
• Increased tearing
• Changes in eyelash length, thickness, or number
• Darkening of the iris (colored part of the eye)
• Darkening of the skin around the eyelids

When to Contact Your Doctor Immediately

• Severe or persistent eye pain
• Noticeable vision changes that don’t improve quickly
• Signs of infection (swelling, pus-like discharge, intense redness)
• Signs of allergic reaction (swelling of face or throat, difficulty breathing, rash)

Note: Some side effects, such as iris color darkening, may be permanent. Others, like eyelash changes, typically reverse after stopping treatment.

Precautions Before and During Rocklatan Use

Before starting Rocklatan, inform your eye care provider about your full medical history. This includes:

• Any current or past eye conditions (such as inflammation, infection, or surgery)
• Kidney or liver disease
• Known allergies to medications or preservatives in eye drops
• Pregnancy or breastfeeding status
• Use of contact lenses

Special Considerations

• Pregnancy & Breastfeeding: Research on Rocklatan use during pregnancy is limited. Your doctor will weigh potential benefits against any possible risks.
• Other Eye Medications: If you use multiple drops, your provider will give instructions on timing to avoid interaction.
• Surgery Plans: Tell your surgeon if you are using Rocklatan before any eye surgery, as certain drugs can affect healing.

Drug Interactions with Rocklatan

Rocklatan may interact with other medications, which could either reduce its effectiveness or increase the likelihood of side effects. That’s why it’s essential to keep your healthcare provider informed about everything you’re taking—including prescriptions, over-the-counter drugs, vitamins, and herbal supplements.

Medications That May Interact with Rocklatan

• Other eye pressure medications – Using multiple glaucoma drops may require careful timing to prevent one from washing out the other.
• Blood pressure medicines – Some systemic blood pressure drugs can interact with ocular medications, potentially affecting fluid dynamics in the eye.
• Anti-inflammatory drugs – Both steroidal (like prednisone) and nonsteroidal (NSAIDs like ibuprofen) eye treatments can sometimes counteract the effects of prostaglandin analogs.
• Prostaglandin analogs – Taking additional drugs from the same class as latanoprost can increase the risk of side effects without extra benefit.

Timing Tips to Avoid Interactions

• If you’re prescribed more than one type of eye drop, wait at least 5 minutes between each medication.
• Apply Rocklatan exactly at the scheduled time your doctor recommends—usually at night.
• Never change the timing or frequency of your drops without professional advice.

Providing your full medication list to both your ophthalmologist and pharmacist ensures they can spot potential issues before they become problems.

Proper Storage of Rocklatan

Correct storage of Rocklatan is essential to maintain its potency and prevent contamination. Both temperature control and handling matter.

Before Opening the Bottle

• Store unopened bottles in the refrigerator at a temperature of 36°F to 46°F (2°C to 8°C).
• Keep the medication in its original box to protect it from light.

After Opening the Bottle

• Once opened, Rocklatan can be kept at room temperature—generally between 68°F to 77°F (20°C to 25°C)—for up to 6 weeks (or as directed by your pharmacist).
• Always replace the cap tightly after use to prevent contamination.
• Avoid touching the dropper tip with your hands, eyelids, or any other surface.

General Storage Tips

• Do not freeze Rocklatan—freezing can damage the active ingredients.
• Keep out of reach of children and pets.
• Check the expiration date before each use.
• Discard the bottle when your pharmacist advises, even if there’s leftover solution.

Proper storage is not just about following instructions—it’s about ensuring you’re getting the full therapeutic benefit from each drop.

Long-Term Use and Monitoring

Rocklatan is not a quick-fix medication—it’s part of a long-term strategy for controlling eye pressure. Stopping suddenly can cause pressure to rise again, which increases the risk of optic nerve damage.

Why Ongoing Use is Important

• Glaucoma and ocular hypertension are chronic conditions.
• Even when symptoms are not noticeable, eye pressure can still be damaging your vision silently.
• Consistent nightly use helps maintain stable pressure and prevent vision loss.

Monitoring Requirements

Your ophthalmologist will schedule regular follow-up appointments to:

• Measure intraocular pressure (IOP)
• Examine the optic nerve for changes
• Check for side effects or complications from the medication
• Determine whether your treatment plan needs adjustments

These visits are usually every 3–6 months, though your schedule may vary depending on your condition and how well your pressure is controlled.

Practical Tips for Success with Rocklatan

Using Rocklatan correctly every day can seem simple in theory, but life’s distractions can lead to missed doses. Here are some practical, real-world tips to stay on track:

1. Set a nightly reminder – Use your phone alarm or a dedicated medication reminder app.
2. Link it to a habit – Apply your drops right before brushing your teeth at night so it becomes automatic.
3. Keep a backup bottle – If possible, have a spare prescription on hand in case you lose or damage your current one.
4. Travel smart – If traveling, store your medication in a small insulated bag to protect it from extreme temperatures.
5. Track your symptoms – Keep a small journal of any eye changes so you can discuss them with your doctor.

Small changes in routine can make a big difference in ensuring your treatment works as intended.

Taking Control of Your Eye Health

Rocklatan is more than just another prescription—it’s a key tool in protecting your vision. Its dual-action formula offers a strong defense against high eye pressure, and with proper use, it can help preserve sight for years to come.

Your Role in Successful Treatment

• Follow instructions exactly – Consistency is the single most important factor in controlling IOP.
• Stay informed – Understand your medication, how it works, and why timing matters.
• Be proactive – Report unusual side effects promptly.
• Commit to regular check-ups – Skipping visits can allow silent damage to progress.

With cooperation between you and your eye care team, Rocklatan can be a safe, effective, and manageable part of your long-term vision care plan.

Understanding Glaucoma and Ocular Hypertension

To fully appreciate how Rocklatan works and why consistent use matters, it helps to understand the conditions it treats.

Glaucoma

Glaucoma is often called the “silent thief of sight” because it typically causes no pain and minimal early symptoms. By the time vision changes become noticeable, irreversible damage to the optic nerve may have already occurred.

• Open-angle glaucoma, the most common type, happens when the drainage angle of the eye remains open but becomes less efficient at letting aqueous fluid out.
• This leads to a gradual buildup of pressure that can eventually compress and damage the optic nerve.

Ocular Hypertension

Ocular hypertension is when eye pressure is above normal limits but without optic nerve damage or vision loss yet.

• It’s a warning sign, and treatment aims to prevent the development of glaucoma.
• Not everyone with ocular hypertension will develop glaucoma, but risk factors such as family history, age, or thin corneas increase the likelihood.

Both conditions share a common goal in treatment: lowering intraocular pressure to protect the optic nerve—and that’s where Rocklatan comes in.

How Rocklatan Works in the Eye

Rocklatan’s effectiveness lies in its two-pronged approach to lowering IOP.

Netarsudil (0.02%)

• Belongs to a class called rho kinase inhibitors.
• Works mainly by increasing the outflow of aqueous humor through the trabecular meshwork—the eye’s primary drainage channel.
• Also reduces the production of aqueous humor, so less fluid enters the eye in the first place.

Latanoprost (0.005%)

• Part of the prostaglandin analog family.
• Enhances uveoscleral outflow, an alternative drainage route in the eye.
• Works over several hours, which is why evening application helps maintain lower pressure overnight.

By combining these two mechanisms, Rocklatan attacks high eye pressure from multiple angles, offering a greater chance of keeping it under control compared to single-agent therapy.

Who Should and Should Not Use Rocklatan

While Rocklatan is effective for many patients, it isn’t for everyone.

Ideal Candidates

• Adults diagnosed with open-angle glaucoma or ocular hypertension.
• Those who have not achieved target IOP with a single medication.
• Patients who prefer once-daily dosing for convenience and adherence.

Who Should Avoid or Use with Caution

• Individuals allergic to netarsudil, latanoprost, or any ingredients in the solution.
• Patients with a history of severe eye inflammation.
• Those who have had recent eye surgery without clearance from their doctor.
• Pregnant or breastfeeding women, unless benefits outweigh risks.

Your ophthalmologist will decide if Rocklatan is the best choice based on your medical history, current eye health, and other medications you may be taking.

---

Possible Long-Term Effects

Like many glaucoma medications, Rocklatan can cause gradual changes in your eyes or surrounding skin with prolonged use.

Iris Color Changes

• Latanoprost can cause darkening of the iris, especially in people with mixed-color eyes (green-brown, blue-brown, hazel).
• The change happens slowly and may be permanent, even if the medication is stopped.

Eyelash Growth

• Eyelashes may grow longer, thicker, or darker over time.
• Some patients see this as a cosmetic bonus, but it’s technically a side effect.

Skin Darkening

• The skin on the eyelids may darken due to pigment changes.
• This usually fades slowly after discontinuing treatment but may persist in some cases.

While these changes are generally harmless, any unexpected or bothersome effects should be discussed with your eye care provider.

Lifestyle Considerations for Better Eye Health

Medication is only part of the strategy for managing high eye pressure. Lifestyle habits can also support your treatment and protect your vision.

Helpful Habits

• Maintain a healthy diet – Focus on leafy greens, citrus fruits, and foods rich in antioxidants.
• Exercise regularly – Activities like walking or swimming can help overall circulation, but avoid inverted yoga poses or heavy lifting that might increase eye pressure.
• Manage stress – Chronic stress can affect your overall health, including your eyes.
• Stay hydrated – Drink water steadily throughout the day rather than in large amounts at once, which may temporarily raise eye pressure.

Avoid These Risks

• Smoking – Linked to worsening eye health and increased glaucoma risk.
• Excessive caffeine – May cause short-term eye pressure spikes.
• Skipping follow-up visits – Glaucoma can progress silently without regular monitoring.
