This helps relieve the eye pressure associated with conditions like glaucoma or ocular hypertension.<\/p>\n\n\n\n<div class=\"quick-facts-card\">\n  <table class=\"quick-facts-table\">\n    <colgroup>\n      <col\/>\n      <col\/>\n    <\/colgroup>\n\n    <thead>\n      <tr>\n        <th colspan=\"2\">Quick Facts<\/th>\n      <\/tr>\n    <\/thead>\n\n    <tbody>\n      <tr>\n        <td><strong>Common Brands<\/strong><\/td>\n        <td>Xalatan, Iyuzeh, Xelpros<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Drug Class<\/strong><\/td>\n        <td>Prostaglandin analog<\/td>\n      <\/tr>\n\n      <tr>\n        <td><strong>Generic Status<\/strong><\/td>\n        <td>Generic is available.<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Availability<\/strong><\/td>\n        <td>Prescription only<\/td>\n    <\/tbody>\n  <\/table>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-dosing\">Dosing<\/h2>\n\n\n\n<p>The typical recommended dose for latanoprost is one drop administered into the affected eye(s) once daily, usually in the evening. The prescription label will have specific instructions for how to apply latanoprost, but here are the general guidelines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wash and clean your hands.<\/li>\n\n\n\n<li>If wearing contact lenses, remove them. You may put them back in after 15 minutes.<\/li>\n\n\n\n<li>Tilt your head back and pull the lower eyelid down with a finger.<\/li>\n\n\n\n<li>Without touching the dropper to your eye, squeeze one drop into the eye.<\/li>\n\n\n\n<li>Close your eye and gently press the inside corner of the eye to help spread the medication.<\/li>\n<\/ul>\n\n\n\n<p><em><strong>Note:<\/strong> Dosing information below is educational only.

Stop using latanoprost and call your doctor immediately if you experience:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Severe allergic reactions:<\/strong> Symptoms include swelling of the face, lips, tongue, or throat; difficulty breathing or swallowing; racing heart; severe rash or itching; and\/or fever.\u00a0<\/li>\n\n\n\n<li><strong>Macular edema:<\/strong> This swelling of the retina can lead to vision changes, including wavy or blurry vision or colors appearing dull.<\/li>\n\n\n\n<li><strong>Severe eye inflammation:<\/strong> Latanoprost may cause or worsen eye inflammation, including increased redness, swelling, or pain.<\/li>\n\n\n\n<li><strong>Herpes eye infection:<\/strong> In people with a history of herpes keratitis, latanoprost may increase the risk of the infection returning.<\/li>\n\n\n\n<li><strong>Bacterial eye infection:<\/strong> Serious eye infections affecting the cornea can occur if the latanoprost bottle gets contaminated. Symptoms include eye swelling and pain.\u00a0<\/li>\n\n\n\n<li><strong>Darker eyes, eyelashes, or eyelids:<\/strong> Latanoprost can cause your iris, eyelashes, or skin around the eyes to get darker. These changes may not appear until months or years later. Changes in eye color may be permanent, but changes in eyelash or skin color typically go away after you stop using the medication.<\/li>\n<\/ul>\n\n<\/div>\n\n\n\n<p class=\"has-muted-color has-text-color\" style=\"font-size:0.875rem\"><em>Call your doctor immediately if you experience any concerning or prolonged symptoms.<\/em><\/p>\n\n\t<\/div>\n<\/section>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pharmacist-tips\">Pharmacist Tips<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-store-latanoprost-properly\">Store Latanoprost Properly<\/h3>\n\n\n\n<p>Unopened bottles of latanoprost should be stored in the refrigerator. Once the bottle is opened, it can be stored at room temperature (up to 77\u00baF) for up to 6 weeks (42 days). Keep the bottle away from light.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-remove-contacts-before-applying\">Remove Contacts Before Applying<\/h3>\n\n\n\n<p>Latanoprost contains a preservative called benzalkonium chloride, which can be absorbed by soft contact lenses. Remove contact lenses before applying the drops and wait at least 15 minutes before putting them back in.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-avoid-contaminating-the-eye-dropper-or-bottle\">Avoid Contaminating the Eye Dropper or Bottle<\/h3>\n\n\n\n<p>To prevent serious infections, never touch the dropper tip to your eye, fingers, or any other surface. Wash and clean your hands before and after using latanoprost.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-apply-other-eye-drops-5-minutes-apart\">Apply Other Eye Drops 5 Minutes Apart<\/h3>\n\n\n\n<p>If you use other eye drops, wait at least 5 minutes between applying latanoprost to allow each medication to be absorbed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-be-careful-with-blurry-vision\">Be Careful With Blurry Vision<\/h3>\n\n\n\n<p>Your vision may be temporarily blurry after applying latanoprost. Avoid driving or operating machinery until your sight clears.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-do-not-double-up-on-doses\">Do Not Double Up on Doses<\/h3>\n\n\n\n<p>If you miss a dose of latanoprost, use it as soon as you remember, unless it is time for your next dose. In that case, skip the missed dose and apply your next dose as usual.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-drug-interactions\">Drug Interactions<\/h2>\n\n\n\n<p>Certain medications and substances can interact with latanoprost, potentially altering how it works or increasing the risk of side effects. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Other prostaglandin analogs:<\/strong> Using latanoprost concurrently with other prostaglandin eye drops (such as bimatoprost or travoprost) is generally not recommended unless directed by a healthcare provider. Doing so may negatively affect the medication\u2019s ability to lower eye pressure.<\/li>\n\n\n\n<li><strong>Thimerosal-containing drops:<\/strong> If latanoprost is used at the same time as eye drops containing the preservative thimerosal, cloudiness may occur. These medications should be administered at least 5 minutes apart.<\/li>\n<\/ul>\n\n\n\n<p>Always give your doctor and pharmacist a complete list of all your medications, vitamins, and supplements to check for potential interactions.<\/p>\n\n\n\n<section class=\"telyrx-faq-section\" data-toc-title=\"FAQs\">\n\t<h2 class=\"telyrx-faq-heading\">FAQs<\/h2>\n\t\t<div class=\"telyrx-faq-items\">\n\t\t\n\n<details class=\"telyrx-faq-item\">\n\t<summary class=\"telyrx-faq-question\">\n\t\t<span class=\"telyrx-faq-question-text\">Can latanoprost permanently change my eye color to brown?<\/span>\n\t\t<svg class=\"telyrx-faq-chevron\" width=\"20\" height=\"20\" viewBox=\"0 0 20 20\" fill=\"none\" aria-hidden=\"true\">\n\t\t\t<path d=\"M5 7.5L10 12.5L15 7.5\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\/>\n\t\t<\/svg>\n\t<\/summary>\n\t<div class=\"telyrx-faq-answer\">\n\t\t\n\n<p>Yes, this is a known side effect.
