Alphagan P® Ophthalmic Solution for Ocular Hypertension and Open-Angle Glaucoma

This prescription eye drop helps lower high eye pressure. It is used for open-angle glaucoma and ocular hypertension. You can order with US shipping from Canada, and we list options for brimonidine eye drops without insurance.

What Alphagan P Is and How It Works

Alphagan P® contains brimonidine tartrate, an alpha-2 adrenergic agonist. It lowers intraocular pressure by reducing aqueous humor production and may increase uveoscleral outflow. These actions help protect the optic nerve over time when used as directed.

Alphagan P eye drops are typically used alone or with other pressure-lowering treatments. The active ingredient targets receptors in the ciliary body to reduce fluid formation. It can be part of a broader plan for managing chronic eye pressure conditions.

People diagnosed with Ocular Hypertension or Open Angle Glaucoma may be prescribed this medicine. Your prescriber will decide if it fits your situation.

Who It’s For

This medicine is indicated to reduce intraocular pressure in adults with open-angle glaucoma or ocular hypertension. It may be recommended when additional lowering is needed beyond first-line therapies, or when other options are not suitable. People with a history of hypersensitivity to brimonidine or any component should avoid it.

Use caution if you have severe cardiovascular disease, depression, orthostatic hypotension, liver or kidney impairment, or if you take medications affecting norepinephrine pathways. The brimonidine tartrate ophthalmic solution class is not recommended in infants; children are more sensitive to systemic effects. Always follow your prescriber’s guidance.

Dosage and Usage

Follow the directions on your prescription label. Typically, one drop is instilled in the affected eye or eyes three times daily at evenly spaced intervals. If you use more than one topical eye medicine, separate products by at least five minutes to limit washout.

Wash your hands before use. Tilt your head back, look up, and gently pull down the lower eyelid to create a small pocket. Instill a single drop without touching the tip to your eye or skin. Close the eye gently. For added absorption control, you may press a finger at the inner corner of the eye for one to two minutes after dosing.

Remove soft contact lenses before instillation. Wait at least 15 minutes before reinserting lenses unless your clinician advises otherwise. Do not change your schedule without consulting a healthcare professional; use exactly as prescribed.

Strengths and Forms

This treatment is supplied as a sterile ophthalmic solution in multi-dose bottles, commonly in 5 mL. Published strengths include 0.1% and 0.15%. Availability can vary by manufacturer and region. Your prescription will specify the strength and bottle size approved for you.

Some patients may receive brimonidine 0.15% ophthalmic solution when a particular concentration is preferred. Check your label to confirm the strength dispensed. If you have questions about substitutions or preservative systems, ask your pharmacist.

Missed Dose and Timing

If you miss a dose, use it as soon as you remember. If it is close to the next scheduled dose, skip the missed dose and return to your regular timing. Do not double up to make up for a missed dose. Keep doses evenly spaced during waking hours to maintain consistent eye pressure control.

Storage and Travel Basics

Store the bottle at room temperature and keep it tightly closed when not in use. Protect from contamination by avoiding contact between the dropper tip and any surface. Keep out of reach of children and pets. Discard the bottle on the date your pharmacist provides or as labeled.

When traveling, pack your drops in your carry-on with a copy of your prescription. Keep the medicine in its original packaging. Avoid excessive heat or freezing conditions. If your bottle appears damaged or discolored, consult a pharmacist before use.

Benefits

This therapy helps lower intraocular pressure, which may reduce the risk of optic nerve damage when used consistently. It can be used alongside other classes, allowing combination regimens tailored to your needs. The drop format is portable and easy to use with brief technique practice.

Side Effects and Safety

• Eye redness or irritation
• Burning or stinging after instillation
• Dry mouth or throat
• Headache or fatigue
• Blurred vision shortly after dosing
• Allergic eye reactions, including itching

Serious but less common effects may include marked drowsiness, low blood pressure, slow heart rate, or severe allergic reactions. Children are more prone to central nervous system effects. Stop the medicine and seek urgent care for symptoms like trouble breathing, swelling of the face or eyelids, or rash with eye swelling. Contact your prescriber if side effects persist or worsen.

Drug Interactions and Cautions

Tell your prescriber about all medicines you take. Interactions may occur with monoamine oxidase inhibitors, tricyclic antidepressants, central nervous system depressants, antihypertensives, and cardiac glycosides. Using multiple topical eye products may increase irritation; separate instillations by several minutes. Remove contact lenses before each dose and wait before reinsertion.

Do not use if you are allergic to any component. Use caution if you have depression, severe cardiovascular disease, reduced blood pressure, or impaired kidney or liver function. If you are pregnant or breastfeeding, discuss risks and benefits with your clinician.

What to Expect Over Time

With regular use, eye pressure may decrease as directed by your prescriber. Many people use this therapy long term as part of a broader plan that can include other drops or procedures. Keep scheduled eye exams to track pressure and optic nerve health. Adherence, correct drop technique, and spacing with other eye medicines support steady results.

Compare With Alternatives

Some people start with a prostaglandin analog, then add or switch based on response or tolerance. Options include latanoprost, often chosen for once-daily dosing, and combination therapies that pair classes for added effect.

Two options we carry include Combigan and Xalatan Ophthalmic Solution. Your prescriber will decide which class or combination suits your goals and medical history.

Patient Suitability and Cost-Saving Tips

This medicine may suit adults requiring additional pressure reduction or who prefer a non-prostaglandin option.
