Niclosamide is a salicylanilide-class anthelmintic with a niche but irreplaceable role: it is the cleanest, most reliable single-dose treatment for <strong>intestinal cestodes<\/strong> (tapeworms). It is on the WHO Model List of Essential Medicines and has been used continuously since the 1960s.<\/p>\n<h2 class=\"wp-block-heading\">Werkingsmechanisme<\/h2>\n<p>Niclosamide <strong>uncouples oxidative phosphorylation<\/strong> in the tapeworm scolex (head). This depletes parasite ATP, paralyses the scolex, and disrupts its grip on the gut wall. The worm is then partially digested by host enzymes &mdash; you may see fragmented proglottids in stool rather than an intact worm. Niclosamide is essentially not absorbed from the gut (&lt; 5%), which is therapeutically perfect: high luminal concentration, near-zero systemic exposure.<\/p>\n<h2 class=\"wp-block-heading\">Niclosig indications and dose<\/h2>\n<table style=\"width:100%;border-collapse:collapse;margin:14px 0;font-size:14px;\">\n<thead>\n<tr style=\"background:#2c7cb0;color:#fff;\">\n<th style=\"padding:8px;text-align:left;border:1px solid #ddd;\">Indicatie<\/th>\n<th style=\"padding:8px;text-align:left;border:1px solid #ddd;\">Dosering<\/th>\n<th style=\"padding:8px;text-align:left;border:1px solid #ddd;\">Schema<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding:8px;border:1px solid #ddd;\">Beef tapeworm (Taenia saginata)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">2&nbsp;g (4 tablets)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Single dose, chewed on empty stomach<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Pork tapeworm intestinal form (Taenia solium)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">2&nbsp;g (4 tablets)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Single dose; consider laxative 2&nbsp;h post-dose to reduce theoretical cysticercosis risk<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:8px;border:1px solid #ddd;\">Fish tapeworm (Diphyllobothrium latum)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">2&nbsp;g (4 tablets)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Eenmalige dosis<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Dwarf tapeworm (Hymenolepis nana)<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">2&nbsp;g day 1, then 1&nbsp;g daily &times; 6 days<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">7-day course<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>Chew the tablets thoroughly<\/strong>, then swallow with a small amount of water.

Visible passage of fragmented proglottids in stool over the days following the dose is normal. The scolex (head) may not be visible &mdash; that&rsquo;s expected because it&rsquo;s the part the drug works on first.<\/p>\n<h3 class=\"wp-block-heading\">Why chew the tablets?<\/h3>\n<p>Chewing maximises dispersion in the gut lumen where tapeworms live. Swallowing whole reduces local concentration and lowers cure rates.<\/p>\n<h3 class=\"wp-block-heading\">Should I take a laxative after?<\/h3>\n<p>Routine laxative is unnecessary for Taenia saginata or Diphyllobothrium. For Taenia solium specifically, some clinicians give a saline laxative 2&nbsp;h post-dose &mdash; this is to expel proglottids quickly and theoretically reduce the chance of egg release and resulting cysticercosis. Discuss with your clinician.<\/p>\n<h3 class=\"wp-block-heading\">Can niclosamide treat roundworm?<\/h3>\n<p>No. Niclosamide is tapeworm-specific. For roundworm, hookworm, pinworm, or whipworm use albendazole or mebendazole.<\/p>\n<h3 class=\"wp-block-heading\">Why is niclosamide preferred over praziquantel for intestinal tapeworm?<\/h3>\n<p>Both work for intestinal tapeworm. Niclosamide has near-zero systemic absorption, fewer side effects, and is cheaper. Praziquantel is the agent of choice for tissue-stage cestodes (neurocysticercosis), schistosomiasis, and most fluke infections &mdash; broader but more expensive.<\/p>\n<h3 class=\"wp-block-heading\">Is Niclosig safe in pregnancy?<\/h3>\n<p>Limited data; the lack of systemic absorption is reassuring. The first trimester is typically avoided where possible. Discuss with a clinician.<\/p>\n<h3 class=\"wp-block-heading\">Can children take Niclosig?<\/h3>\n<p>Yes from age 2 with weight-band dosing: 11&ndash;34&nbsp;kg = 1&nbsp;g (2 tablets); &gt; 34&nbsp;kg = adult dose. Below age 2, consult a paediatrician.<\/p>\n<h3 class=\"wp-block-heading\">Should I retreat?<\/h3>\n<p>Routine retreat is not standard. Confirm cure with stool testing at 1 and 3 months. If proglottids reappear or stool shows persistent infection, repeat the single dose.<\/p>\n<h3 class=\"wp-block-heading\">What about alcohol after taking Niclosig?<\/h3>\n<p>Avoid alcohol on the day of treatment &mdash; it can theoretically increase niclosamide absorption and is associated with rare reports of nausea and flushing.<\/p>\n<h3 class=\"wp-block-heading\">Can I take other medicines with Niclosig?<\/h3>\n<p>Yes. Because niclosamide is essentially unabsorbed, clinically significant drug interactions are very rare. Standard chronic medications can continue uninterrupted.<\/p>\n<p class=\"medsbase-link-boost-2026-05-10\" data-marker=\"mb-link-boost-iverheal\">When a patient treated with <a href=\"https:\/\/medsbase.com\/nl\/niclosig\/\">Niclosig (niclosamide 500 mg)<\/a> for intestinal tapeworms also presents with scabies or strongyloidiasis, practitioners typically add a separate ivermectin course such as <a href=\"https:\/\/medsbase.com\/nl\/iverheal\/\">Iverheal (ivermectin 3 \/ 6 \/ 12 mg)<\/a> to address the ectoparasitic component.<\/p>\n<p><!-- medsbase-related-alts-v1 --><\/p>\n<h3 class=\"wp-block-heading\">Andere antiparasitaire medicijnen<\/h3>\n<ul>\n<li><a href=\"https:\/\/medsbase.com\/nl\/niclosig\/\">Niclosig (niclosamide 500 mg)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/nl\/prazinec\/\">Prazinec (praziquantel 600 mg)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/nl\/abd-400-albendazole\/\">ABD 400 (albendazole 400 mg)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/nl\/mebex\/\">Mebex (mebendazole)<\/a><\/li>\n<li><a href=\"https:\/\/medsbase.com\/nl\/tinvista\/\">Tinvista (tinidazole)<\/a><\/li>\n<\/ul>\n<div style=\"background:#fff3f3;border-left:4px solid #d9534f;padding:14px 18px;margin:22px 0;border-radius:4px;font-size:14px;color:#444;\"><strong>Medisch disclaimer.<\/strong> Deze pagina is alleen voor educatieve doeleinden en vervangt geen professioneel medisch advies.
