Alphagan® Ophthalmic Solution for Glaucoma and Ocular Hypertension

What Alphagan® Is and How It Works

Alphagan Ophthalmic Solution contains brimonidine tartrate, an alpha-2 adrenergic agonist used to lower elevated intraocular pressure in open-angle glaucoma or ocular hypertension. It is an eye drop solution used in the affected eye or eyes, often as add-on therapy. Many patients look for Alphagan Ophthalmic Solution without insurance to manage ongoing treatment costs.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba; licensed pharmacists review each prescription before dispensing, and we offer brand and generic medicines at Canadian prices along with OTC health products.

Brimonidine reduces aqueous humor production and increases uveoscleral outflow. The combined effect lowers intraocular pressure, which helps protect the optic nerve over time. Alphagan is typically used three times daily, about eight hours apart. It may be used alone or with other glaucoma drops such as beta blockers or prostaglandin analogs.

We work with licensed, vetted international partner pharmacies to supply authentic brand medicines and a broad selection at affordable pricing.

Dosage and Usage

This Alphagan usage guide summarizes common directions. Follow your prescriber’s instructions and the product insert.

• Wash and dry your hands before use.
• If you wear soft contact lenses, remove them. Wait at least 15 minutes before reinserting.
• Tilt your head back and pull down the lower eyelid to make a small pocket.
• Hold the bottle above the eye. Do not touch the tip to your eye or skin.
• Instill 1 drop in the affected eye(s) three times daily, about 8 hours apart.
• After the drop, gently press the inner corner of your eye (punctal occlusion) for 1 minute to limit systemic absorption.
• If using other eye medications, wait 5–10 minutes between products.
• Missed dose: use it when remembered unless it is near the next dose. Do not double up.
• Do not drive until vision clears if you experience temporary blur after dosing.

Alphagan drops dosage may be adjusted by your prescriber if you are using multiple glaucoma agents.

• Store at 15–25 °C (59–77 °F). Do not freeze. Protect from light.
• Keep the cap tightly closed. Avoid contaminating the dropper tip.
• Discard the bottle 28 days after first opening, or sooner if advised.
• When traveling, keep the bottle in your carry-on to avoid temperature extremes.
• Do not leave the bottle in a hot car or direct sunlight.

Benefits and Savings

Alphagan lowers intraocular pressure by two pathways, which helps slow optic nerve damage in glaucoma. Many people use Alphagan when beta blockers are not suitable or as add-on to reach target pressure. The drop is quick to use and fits into daily routines.

You can buy Alphagan eye drops online at Canadian pricing and often see 60–80% savings versus typical US prices. This can be helpful for ongoing therapy, especially if you pay Alphagan solution out of pocket or manage costs without insurance. Multi-month supplies and bulk promotions can further reduce the per-month expense.

Side Effects and Safety

• Common: eye redness, burning or stinging, itching, dry eyes, blurred vision.
• Systemic: dry mouth, fatigue, drowsiness, headache, dizziness.
• Other ocular: foreign body sensation, eyelid redness or swelling, allergic conjunctivitis.

Serious but less common reactions include marked eye allergy, significant eye swelling, severe redness, low blood pressure, or slow heartbeat. Stop use and seek care if you notice severe symptoms. Do not use in infants under 2 years due to risk of apnea and CNS depression. Use caution in children 2–6 years. Avoid use with monoamine oxidase (MAO) inhibitors; tricyclic antidepressants may reduce effect. Sedation may increase with alcohol or other CNS depressants. Contact lens wearers should remove lenses before dosing due to benzalkonium chloride preservative.

Onset Time

Intraocular pressure reduction can begin within 1–4 hours of instillation, with peak effect near 2 hours and sustained benefit between doses. As your dosing schedule stabilizes, your clinician will assess pressure responses over days to weeks. Longer-term control is evaluated over several follow-up visits.

Compare With Alternatives

Prostaglandin analogs are often first-line for glaucoma due to once-daily dosing and strong efficacy. If you prefer once-nightly dosing, your prescriber may consider Xalatan® Ophthalmic Solution (latanoprost). These agents can cause eyelash growth or iris color change in some users.

Lumigan® Rc (bimatoprost) is another prostaglandin analog option used once nightly. It is effective for many patients but shares similar class effects on lashes and periocular skin.

Within the brimonidine family, Alphagan P is a related product preserved with Purite and usually available at 0.1% or 0.15% strengths. Some patients who experience ocular allergy with benzalkonium chloride prefer that formulation. Discuss Alphagan vs generic alternatives with your prescriber to align efficacy, comfort, and dosing needs.

Combination Therapy

• With prostaglandin analogs: space drops by 5–10 minutes to prevent washout.
• With beta blockers (e.g., timolol): monitor for additive blood pressure or pulse effects.
• With carbonic anhydrase inhibitors (e.g., dorzolamide): follow the prescribed sequence and spacing between drops.
• General: use punctal occlusion for 1 minute after each drop to reduce systemic exposure.

Patient Suitability and Cost-Saving Tips

Alphagan is used for adults with open-angle glaucoma or ocular hypertension who need additional pressure lowering or who cannot use other classes. It is not for acute angle-closure situations. Tell your prescriber about heart disease, low blood pressure, depression, Raynaud phenomenon, or liver/kidney problems. Avoid in infants; use caution in young children. If pregnant or breastfeeding, discuss risks and alternatives with your clinician.

Contact lens wearers should remove lenses before dosing and wait 15 minutes before reinsertion. If you experience ongoing redness or irritation, speak with your eye-care professional.

Set simple reorder reminders so you do not miss doses. Ordering a multi-month supply can lower the Alphagan Ophthalmic Solution price per month, and occasional Alphagan promotional offers may help. Some patients look for Alphagan cash purchase options when budgeting for long-term therapy.
