Giardiasis is a parasitic disease affecting the gastrointestinal tract of animals and humans, transmitted through contaminated food and water or through direct contact with an infected person (fecal-oral). In addition, there is the possibility of transmission during anal or oral sex.

    • 2.2 Tinidazole
    • 2.3 Ornidazole
    • 2.4 Vermox
  • 3 Prevention

The causative agents of the disease are unicellular intestinal flagellates Giardia intestinalis, which arise in a vegetative (trophozoite) and cystous (cyst) form.

The treatment of giardiasis today is not as complicated as it used to be, and there are various drugs and tablets for lamblia in adults on the market. Consider what to guide you when choosing a treatment.

Clinical signs

G. intestinalis is the originator of an alimentary diarrheal disease known as giardiasis. Despite the massive conclusions of the analyzes, it does not necessarily come to pathological changes. Most infections are either asymptomatic or subclinical. Only 10% of those infected have clinical manifestations

The acute stage of giardiasis has a short course (3-4 days) and often mimics acute viral enteritis, bacterial dysentery or other bacterial food poisoning, acute intestinal amebiasis or diarrhea caused by toxigenic strains of E. coli.

The incubation period for the acute phase is 12-20 days. Manifested by sudden diarrhea, loss of appetite, nausea, vomiting, and increased flatulence. The stool is light, watery, with a strong odor, containing a large amount of fat (greasy appearance) and mucus, without blood, cellular elements and remnants of worms.


The subacute and chronic phase is manifested by pressing pain in the epigastrium and hypochondria, especially after eating. Diarrhea alternates with constipation, and children have secondary anemia and slow weight gain.

After a few weeks, spontaneous healing can be achieved. Sometimes the disease persists for several months or even years, turning into an asymptomatic form associated with the carriage of cysts.

In addition to the intestinal form of giardiasis, a hepatobiliary form can be demonstrated (in 50% of cases). It manifests itself in the form of acute or chronic cholecystitis. With severe damage to the intrahepatic bile ducts and liver parenchyma, jaundice and hepatomegaly may develop.


In the treatment of lamblia tablets, a popular medicine is Metronidazole (Flagil), which is taken in adults in a dose of one tablet (250 mg) 3 times a day. The therapeutic course is 10 days. The recommended dosage for children is 5 mg / kg three times a day. Duration - 5-10 days.

An alternative treatment is Ornidazole (Avrazor), which is taken twice a day, 500 mg. The therapeutic course is 5-10 days.

If the treatment with the above drugs does not show efficacy, Tinidazole (Fazizin) 2 g can be used once (children - 50-75 mg / kg once).

The mechanism of action of these drugs for giardiasis is the effect on the enzyme process of the parasite, which causes its destruction. The effectiveness of therapy is monitored by microscopic examination 2 weeks after its completion.

Women can use the drug to treat deep pelvic inflammation and gynecological infections (both bacterial in nature and those caused by protozoa).
