It stops bacterial growth without disrupting normal human cellular processes.<\/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>Ilotycin, Romycin<\/td>\n      <\/tr>\n\n      <tr>\n         <td><strong>Drug Class<\/strong><\/td>\n        <td>Ophthalmic macrolide antibiotic<\/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>For the treatment of active eye infections, providers typically recommend applying a 1-centimeter ribbon of erythromycin ophthalmic ointment to the affected eye(s) up to 6 times a day, depending on the severity of the infection. Your doctor will provide instructions about how often to use the ointment.<\/p>\n\n\n\n<p>When applying the medication, it is generally advised to tilt the head forward or slightly back, pull down the lower eyelid to form a small pouch, and squeeze the ointment into this space.<\/p>\n\n\n\n<p><em><strong>Note:<\/strong> Dosing information below is educational only. Your prescribing physician will determine your specific dose based on your individual health needs.\u00a0Always follow your healthcare provider\u2019s instructions for exact dosing.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-uses\">Uses<\/h2>\n\n\n\n<p><strong>FDA-Approved Uses<\/strong><\/p>\n\n\n\n<p>Erythromycin ophthalmic ointment is FDA-approved to treat bacterial infections that affect the surface of the eye. These conditions include conjunctivitis (pink eye) and blepharitis, which are caused by bacteria that are affected by erythromycin.<\/p>\n\n\n\n<p><strong>Off-Label Uses<\/strong><\/p>\n\n\n\n<p>You may see erythromycin ophthalmic ointment prescribed for uses that are not &#8220;FDA-approved.&#8221; This is a common and legal practice called &#8220;off-label&#8221; prescribing, where a doctor uses their clinical judgment to prescribe a drug for a different (but well-researched) purpose.<\/p>\n\n\n\n<p>Erythromycin ophthalmic ointment may be prescribed off-label to treat styes that do not improve with non-medical treatments, such as warm compresses and eyelid scrubs.<\/p>\n\n\n<div class=\"telyrx-email-cta telyrx-email-cta--banner alignfull wp-block-telyrx-email-signup\">\n\t\t<h2 class=\"telyrx-email-cta__heading\" data-toc-hidden=\"true\">Get Savings Updates<\/h2>\n\t<p class=\"telyrx-email-cta__description\">Join our mailing list for exclusive deals and more.<\/p>\n\t\t\t<form\n\t\t\tid=\"telyrx-email-form-1\"\n\t\t\tclass=\"telyrx-email-cta__form\"\n\t\t\tdata-portal-id=\"46401311\"\n\t\t\tdata-form-id=\"14e1d7d5-6b17-4228-b42e-c06d1a6c240b\"\n\t\t\tdata-i18n=\"{&quot;subscribe&quot;:&quot;Subscribe&quot;,&quot;success&quot;:&quot;Thanks!

Seek immediate medical care if you experience signs of an allergic reaction to this ointment.<\/li>\n\n\n\n<li><strong>Secondary eye infections<\/strong>: Using this medication over a long period can sometimes contribute to an infection with other types of germs, such as fungi. This can cause symptoms such as worsening blurry vision, pinkness, or eye discharge.<\/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-wash-your-hands-frequently\">Wash Your Hands Frequently<\/h3>\n\n\n\n<p>Wash your hands with soap and water before and after applying the ointment.
