Glaucoma
Glaucoma
Glaucoma is a group of eye conditions that harm the optic nerve, usually when intraocular pressure — the pressure inside the eye — stays too high; this category introduces prescription therapies, support items, and plain-language guides for people reducing vision risk. You can compare brands, dosage forms, and strengths across pressure-lowering medicines and combinations, then review handling steps and storage basics; availability can vary by strength or brand, and inventory may change without notice, with US shipping from Canada offered on many listed items. Use this page to understand how drug classes differ, when each is used, and how they fit into a clinician’s plan for treatment and follow-up.
What’s in This Category – Glaucoma
This category highlights pressure-lowering ophthalmic therapies and related information. It covers prostaglandin analogs, beta-blockers, alpha agonists, carbonic anhydrase inhibitors, Rho kinase inhibitors, and nitric oxide–donating agents. You will also see fixed-dose combinations that pair complementary mechanisms in one bottle. Formats include multi-dose solutions, sterile single-use vials, and, less often, suspensions that need gentle shaking before use.
Typical users include adults diagnosed after routine screenings, older adults with multiple medicines, and some adolescents under specialist care. Many regimens begin with a once-daily prostaglandin analog, then add another class if targets are not met. Combination bottles can reduce bottle burden and simplify timing. This section also points to education on spacing drops, minimizing systemic absorption, and coordinating refills with clinic follow-up.
How to Choose
Selection starts with the diagnosis, target pressure, and tolerance history. Many adults prefer glaucoma eye drops for local action and dosing flexibility. Your prescriber may prioritize once-daily options to improve adherence, then consider combinations if two mechanisms are needed. Discuss contact lens wear, preservatives, and bottle dexterity to avoid avoidable irritation or missed doses.
Storage and handling also influence the best fit. Some bottles require discarding after a set number of days once opened. Keep caps closed, avoid dropper tip contact, and use punctal occlusion to limit taste or dizziness. If you take systemic beta-blockers or have airway disease, your clinician may avoid certain classes.
- Common mistake: layering doses too closely and washing one drop out with the next.
- Common mistake: touching the dropper tip to the eye or lashes and contaminating the bottle.
- Common mistake: skipping follow-up pressure checks after changing a regimen.
Popular Options
The examples below illustrate how different classes are used. This glaucoma medication choice always depends on your diagnosis, target pressure, and tolerability. Use these examples to compare dosing schedules, bottle types, and common add-on strategies.
Vyzulta delivers latanoprostene bunod, a prostaglandin analog with a nitric oxide–releasing component that helps fluid outflow through two pathways. It is generally dosed once nightly and is often a first-line option. See product details for storage notes and bottle format on Vyzulta Ophthalmic Solution.
Trusopt contains dorzolamide, a topical carbonic anhydrase inhibitor often used as an add-on when a single agent is not enough. Many patients dose it two to three times daily, depending on the plan. Review strength, preservatives, and compatible combinations on Trusopt (dorzolamide).

Frequently Asked Questions
What can I compare on this page before I order?
You can compare prescription eye drop classes, bottle formats, and strengths. Review typical dosing frequency, storage notes after opening, and preservative content. You can also scan example products to see which options are once daily versus multiple times per day. Final choices should follow your clinician’s plan and local prescribing rules.
Do I need a prescription to purchase pressure-lowering eye drops?
Most pressure-lowering eye drops require a prescription under US and Canadian regulations. Some lubricants or support items may be available without one, but they do not lower pressure. Confirm your eligibility and provide a valid prescription when required. Your clinician should set treatment goals and follow-up timing before you place any order.
How do I know which strength or bottle size to choose?
Your eye care professional sets the strength and dosing schedule. You can review available strengths and bottle sizes on each product page to match your prescription. Consider refill timing, preservative content, and discard-after-opened guidance. If dexterity or contact lens wear affects use, ask your clinician about devices, single-use vials, or preservative-free options.
Can I switch between brands or generics in this category?
Switching between brands or generics should be supervised by your prescriber. Even small changes in bottles, preservatives, or dosing can affect tolerability and adherence. If a specific product is unavailable, your clinician can recommend an equivalent option. Document changes and schedule a pressure check after any substitution to confirm that targets remain on track.
What if my order contains items with different storage instructions?
Follow the storage directions on each product label and the enclosed guide. Many multi-dose bottles store at room temperature, but some single-use vials may have different rules. Track the “discard after opening” window to avoid contamination. Separate items by schedule and keep caps closed tightly to protect sterility and potency.
