What Are They and Why Do Eye Doctors Prescribe Them?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When an eye doctor diagnoses a fungal infection of the cornea, <strong>natamycin eye drops<\/strong> are often among the first treatments considered. Natamycin is a long-established antifungal, yet it remains one of the most important tools in ophthalmology against fungal infection. This educational guide explains what natamycin is, how it works, when it is used and why it should never be used without a prescription.<\/p>\n<figure style=\"margin: 0 0 18px;\"><img fetchpriority=\"high\" decoding=\"async\" style=\"max-width: 100%; height: auto; border-radius: 10px;\" src=\"https:\/\/nostylelike.net\/wp-content\/uploads\/2026\/10\/nat-article-guide-en.jpg\" alt=\"natamycin eye drops \u2013 Natamycin Eye Drops\" width=\"1200\" height=\"675\" \/><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"What_Is_Natamycin\"><\/span>What Is Natamycin?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Natamycin, also known as pimaricin, is an antifungal substance produced naturally by Streptomyces bacteria. It belongs to the polyene family, the same group as nystatin and amphotericin B.<\/p>\n<p>In eye care, natamycin eye drops come as a sterile 5% ophthalmic suspension. One example on the market is <a href=\"https:\/\/nostylelike.net\/en\/product\/natamet-eye-drops-5-5ml\/\">Natamet 5% eye drops<\/a>. \u201cSuspension\u201d means the drug particles are spread through the liquid rather than dissolved, which is why the bottle must be shaken before every use.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Do_Natamycin_Eye_Drops_Work\"><\/span>How Do Natamycin Eye Drops Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Natamycin binds to ergosterol in the fungal cell membrane. This changes the membrane\u2019s permeability, and the cell loses essential components. Its main action is fungicidal \u2013 it kills the fungus rather than only slowing its growth.<\/p>\n<p>Because human cells contain cholesterol instead of ergosterol, the effect is focused on fungi. When applied to the eye, very little natamycin is absorbed into the bloodstream.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"When_Do_Eye_Doctors_Use_Natamycin_Eye_Drops\"><\/span>When Do Eye Doctors Use Natamycin Eye Drops?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Fungal keratitis, especially infections caused by filamentous fungi such as Fusarium and Aspergillus.<\/li>\n<li>Fungal conjunctivitis.<\/li>\n<li>Fungal blepharitis (eyelid infection).<\/li>\n<\/ul>\n<p>You can read more about the most important of these conditions in our article on <a href=\"https:\/\/nostylelike.net\/en\/fungal-keratitis\/\">fungal keratitis<\/a>, its symptoms and causes.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_Are_Natamycin_Eye_Drops_Prescription_Only\"><\/span>Why Are Natamycin Eye Drops Prescription Only?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Fungal eye infections look very similar to bacterial and viral infections, and even to allergies. Using an antifungal for a bacterial infection will not help and can delay the right treatment until the cornea is damaged. That is why the doctor relies on a slit-lamp examination and, often, a corneal scraping for culture before starting treatment.<\/p>\n<p>The treatment schedule also varies greatly between cases, and patients need close follow-up to assess response. The decision therefore always belongs to the doctor.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Practical_Points_Your_Doctor_Will_Usually_Explain\"><\/span>Practical Points Your Doctor Will Usually Explain<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Shake the bottle well before every use.<\/li>\n<li>Do not let the dropper tip touch the eye or fingers.<\/li>\n<li>Wait 5 minutes between different eye drops.<\/li>\n<li>Do not wear contact lenses during treatment.<\/li>\n<li>Discard the bottle one month after opening.<\/li>\n<li>Do not stop early even if the pain improves.<\/li>\n<\/ul>\n<p>Following these points helps natamycin eye drops work as intended and lowers the risk of contamination or relapse.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Do_Natamycin_Eye_Drops_Have_Side_Effects\"><\/span>Do Natamycin Eye Drops Have Side Effects?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Most are local and mild, such as stinging, redness and brief blurred vision, but some symptoms need a doctor\u2019s review.

Natamycin is a prescription medicine used only under the supervision of a specialist eye doctor, not for self-use, and this article does not replace a medical examination.<\/p>\n<p style=\"font-size: 0.95em; color: #555;\">Stop and see your doctor immediately if pain increases or vision worsens.
