Levamisole 10 instructions for use in veterinary medicine. Levamisole: instructions for use against worms. Dosage for different types of animals

"Levamisole" refers to anthelmintic and immunomodulatory drugs. The active ingredient is levamisole hydrochloride, which is an odorless white or light pink powder that easily dissolves in water.

Release form

The medicine is available in the form of tablets of 0.15 (adult dose) or 0.05 g (for children), packaged in blisters of one or two pieces, since the treatment course is usually a single dose of the drug.

Pharmacology

The drug paralyzes the muscle tissue of round helminths: hookworms, toxoplasma, roundworms and others. Immobilized helminths are eliminated from the intestines naturally a day after taking the medicine.

In addition, the drug stimulates the formation of antibodies, which increases the body's immune defense. It is absorbed from the intestine in a short time, reaching its highest concentration in the blood two hours after administration. When passing through the liver, it forms inactive metabolites. Partial elimination from the body occurs after three hours, metabolites - after approximately 16 hours.

Indications for use

Prescribed for the following diseases:

  • Enterobiasis
  • Trichostrongyloidosis
  • Necatoriasis
  • Ascariasis
  • Toxoplasmosis
  • Trichocephalosis
  • Strongyloidiasis
  • Hookworm

The average price is from 20 to 60 rubles.

As an immunomodulator "Levamisole" is used to treat:

  1. Autoimmune diseases:
    • Aphthous stomatitis
    • Lupus erythematosus
    • Reiter's syndrome
    • Crohn's disease
    • Rheumatoid arthritis
  2. Malignant tumors during remission:
    • Lymphogranulomatosis
    • Colon cancer
    • Leukemia
    • Breast tumors
    • Bronchial cancer
  3. Long-lasting infections, and with their frequent relapse:
    • Bronchitis
    • Chronic hepatitis B
    • Warts
    • Herpes
    • Pyoderma
    • Sinusitis
    • Viral hepatitis B
    • Shingles.

Contraindications

Rigorous studies have not been conducted on the effect of the drug during pregnancy and lactation. As a result, it is not recommended to take it during this period. The drug is contraindicated in children under seven years of age, as well as in the presence of:

  • Intolerance to the components of the drug
  • Agranulocytosis.

Also, its use should be limited to patients with:

  • Cerebrovascular insufficiency
  • Kidney or liver failure
  • Acute phase of leukemia
  • Depressed bone marrow hematopoiesis.

Before prescribing the drug, blood tests are performed. They are also required during treatment - at least once every three weeks.

Side effects

The most common are abdominal pain, nausea, vomiting and diarrhea. If you take the drug for a long time, urticaria, skin rash, runny nose, headache, fever, nervous disorder and agranulocytosis may occur.

Interaction with other substances

During treatment, you should not drink alcohol - this leads to the development of Antabuse-like syndrome. That is, increased alcohol intolerance occurs, which is usually a consequence of taking Antabuse, a medicine used to cure alcohol dependence.

And also, the drug cannot be used simultaneously with Ethanol, Warfarin, Phenytoin.

Method of administration

The medicine should be taken with food, washed down with water, according to the indicated dosage.

For helminthiasis, the tablet is taken 1 time before bedtime for one day. Dose for children under 6 years of age: 25-50 mg. From 7 to 14 years - 50-125 mg. For children over 14 years of age and adults 150 mg.

If necessary, the course should be repeated after one or two weeks.

For toxoplasmosis, 150 mg of the medicine is taken for 3 days - 1 time per day. Then a break is taken for one week and the course is repeated 2-3 times.

To enhance immunity, the dose is 150 mg (1 dose over 3 days). The course lasts 6-8 months. It is necessary to take a break of 1-2 weeks.

For cancer, the required dose is 50 mg 3 times a day for 3 days. Break - 2 weeks. The course is 1 year.

Overdose

An overdose is manifested by exacerbation of side effects: disruption of the heart, convulsions. In such cases, you need to stop taking the medication, do a gastric lavage (if the drug was taken recently), and drink activated charcoal. Symptomatic treatment is also prescribed. There have been cases of death, so the correct dosage must be observed.

Storage

Store in a dark place, out of reach of children, at a temperature of 15–30°C for no more than five years.

Application in veterinary medicine

For deworming of cows, goats, sheep, pigs and dogs, Levamisole 75 is used, which has the form of a clear solution. It is bottled in glass bottles of 20, 50 and 100 ml, sealed with rubber caps held in place by aluminum fasteners (Nita-Pharm CJSC, Russia). Its analogue is Levamisole 10, which is bottled in 50 and 100 ml bottles made of dark glass (Askont+ LLC, Russia). Levamisole Plus differs from these two drugs in that it is also used to treat birds (Product, Ukraine).

Action diagram

The drugs paralyze the nervous and muscular systems of nematodes, causing their death. Levamisole 75 reaches its maximum concentration within 40 minutes and remains in the blood for approximately 7–8 hours after the injection. It is excreted from the body after 3–7 days, including through breast milk. The same applies to Levamisole 10, which is used to treat poultry, and Levamisole Plus.

Indications for use

Levamisole 75 and other veterinary drugs are used to treat diseases of cows, goats, sheep, pigs, dogs and birds:

  • Cooperiosis
  • Ostertagiosis
  • Esophagostomosis
  • Hemonchoza
  • Strongyloidiasis
  • Habertiosis
  • Nematodirosis
  • Bunostomosis
  • Dictyocaulosis
  • Chiostronigylosis
  • Ascariasis
  • Metastrongylosis
  • Trichuriasis
  • Uncinarium
  • Toxocariasis and toxascariasis
  • Hookworm.

Contraindications

The toxic effect of the drug on the embryos of rats and rabbits and its excretion into the milk of cows has been proven. Therefore, Levamisole 75 and its derivatives are not administered to cows in the final trimester of pregnancy, and to sheep, goats, pigs and dogs in the second half of this period. Also, their use is contraindicated for animals weighing less than 10 kg, with severe malnutrition, infectious diseases and intolerance to the components of the drug.

Levamisole is the international nonproprietary name of a chemical substance with anthelmintic properties. Its action is characterized by a narrow focus. The drug of the same name is active only against certain types of roundworms. Instructions for use of Levamisole contain information about its pharmacological properties, describe the method of use, indicate the presence of side effects and contraindications. To achieve the desired result, it is important to strictly follow the recommendations for use.

The drug is primarily used to treat ascariasis. It shows less effectiveness against necatoriasis and hookworm disease.

How does Levamisole work?

Some sources say that drugs based on Levamisole have immunomodulatory properties. There is no such information in the official instructions. Sometimes doctors prescribe Levamisole as a drug that enhances the body's protective functions. The indications in this case are:

  • Hepatitis B;
  • the presence of herpes virus types 1 and 2;
  • rheumatoid arthritis;
  • Crohn's disease;
  • Reiter's disease;
  • recovery period after chemotherapy and radiation therapy in the treatment of cancer.

Levamisole is 95% absorbed in the intestine and quickly enters the bloodstream. Its maximum plasma concentration is detected within the first 1.5-2 hours after oral administration. Half-life is the time during which the drug loses its pharmacological activity by half. For Levamisole it is 3-6 hours.

The substance is neutralized by the liver. Here it decomposes into non-toxic compounds. Only 5% of the drug is excreted unchanged. Most of it is excreted in urine, the rest in feces.

Instructions for use

Dosage form - tablets. Available in 1 piece, sealed in a blister. Packaging - cardboard box. One tablet contains 150 mg of levamisole hydrochloride.

The drug is prescribed to adults and children over 14 years of age. The instructions do not allow the use of Levamisole in persons under the specified age.

The course of treatment is prescribed for the treatment of ascariasis. For rare tropical helminthic infestations - necatoriasis and hookworm disease, the treatment regimen is prescribed individually by the doctor.

For adults

During anthelmintic therapy, the drug is used once in the evening after meals or during meals. Take the tablet with a small amount of water. For adults, a single dose is 150 mg. A repeat course is carried out after 1-2 weeks.

You do not need to adhere to a special diet before treatment. After using Levamisole, there is no need to take laxatives. During anthelmintic therapy, as well as over the next 24 hours, you should abstain from alcohol.

As an immunomodulator, Levamisole is taken in an amount of 150 mg at a time. Or divide the dose into 50 mg and drink it for three days, once a day every two weeks. The number of courses is determined by the doctor.

For children

Levamisole is approved for children over 14 years of age. Treatment is carried out in the same way as in adults, the dose is taken at a time. Children are prescribed 2.5 mg per 1 kg of weight. But usually a single dose is 1 whole tablet.

Is it possible for pregnant and nursing mothers?

There are no data confirming the safety of using Levamisole during pregnancy. It was revealed that in animals the drug in high doses has a toxic effect on the embryo. No adequate studies have been conducted in humans. Therefore, the prescription of Levamisole is advisable only after carefully balancing the benefits for the mother and the risk to the fetus.

There are no studies on the safety of Levamisole during lactation. It is not known whether the active substance is excreted in mother's milk. There is evidence that cows receiving Levamisole have a chemical compound found in their milk. Based on these data, women during lactation may be advised to stop breastfeeding for the period of treatment or ask the doctor to prescribe a safer remedy.

Use of Levamisole in veterinary medicine

Veterinary drugs based on Levamisole are used to treat animals:

  • "Levamisole 75";
  • "Levamisole 8";
  • "Levamisole 10".

"Levamisole 75"

Injection. Transparent colorless liquid with an active substance concentration of 7.5%. Available in dark glass bottles of 20, 50, 100 ml.

The drug is administered parenterally (bypassing the gastrointestinal tract). The maximum concentration in the blood is detected after 30-50 minutes. Levamisole is almost completely excreted unchanged from the body, mainly in the urine and partly in the feces. Excreted in the milk of lactating animals.

The drug is administered once intramuscularly or subcutaneously. For 10 kg of weight, take 1 ml of solution.

Maximum single dose:

  • for cattle - 20 ml;
  • for pigs - 10 ml;
  • for sheep, goats, calves - 5 ml;
  • for dogs - 2.5 ml.

Before treatment, the animal does not need to be kept on a starvation diet. The use of laxatives is also not required. If the dosage is followed, side effects are extremely rare. Individual allergic reactions are possible.

"Levamisole 75" is not used in animals in the second half of pregnancy. Meat can be used no earlier than 7 days after treatment, milk - after three days.

"Levamisole 8"

Water-soluble white powder, packaged in containers or sealed bags. 1 gram of the drug contains 80 mg of active substance.

Used for deworming cattle, sheep, goats, pigs, poultry, dogs. Feed with water or food. Animals are given once in the amount of 1 gram per 10 kg of weight. For poultry - 3-4 grams per 10 kg of weight, fed at a time, or divided into several doses, one per day for 3-4 days. Absorbed in the intestines. Metabolized to non-toxic residues by the liver. Not used in females in the last third of pregnancy.

After deworming, the waiting period for meat is 7 days, for milk and eggs - 3 days.

"Levamisole 10"

1 ml of solution contains 100 mg of medicinal component. Liquid for injection is packaged in bottles of 50 and 100 ml. The nature of action and method of application are the same as Levamisole 75 and are derived in the same way.

Used for the treatment and prevention of helminthiasis in cattle, sheep, goats, and pigs. The dose for cows is 7.5 ml per 100 kg of body weight (but not more than 30 ml), for small animals - 0.75 ml per 10 kg. More than 15 ml of the drug is not injected at the same time; the dose is distributed over 2-3 places. The animal is sent for slaughter no earlier than after 7 days.

All forms of veterinary Levamisole are not allowed to be used in animals that are exhausted or weakened by infections.

Side effects

Levamisole is a drug of moderate toxicity. The instructions indicate the likelihood of adverse reactions occurring in 1% of cases of use.

From the digestive organs the following are observed:

  • abdominal pain;
  • nausea;
  • vomit;
  • diarrhea;
  • obsessive smell of chlorine and metallic taste in the mouth.

From the nervous system:

  • insomnia;
  • nightmares;
  • headache;
  • convulsions;
  • organic brain damage.

There is no sufficient evidence to believe that Levamisole depresses the nervous system. However, given that it may cause slight dizziness, extreme caution should be taken when driving.

Undesirable reactions from the cardiovascular system - palpitations.

On the part of the blood system - a redistribution of indicators towards a decrease in leukocytes or platelets.

Allergic reactions:

  • skin rashes;
  • Quincke's edema.

With a single dose, undesirable effects are not clearly expressed and disappear on their own in a short period. The connection between treatment with Levamisole and encephalopathy (brain damage) is unclear. With early treatment with hormonal drugs, it is possible to completely restore brain function.

Contraindications

First of all, the drug is contraindicated during pregnancy and lactation. Levamisole is not prescribed to patients with known hematopoietic disorders and to children under 14 years of age.

People suffering from lactase deficiency or glucose-galactose malabsorption syndrome (inability to absorb substances) should note that Levamisole tablets contain lactose.

Taking the drug together with alcohol leads to toxic damage to the body. As a result of the reaction, toxic substances are released and histamine production increases. Signs of severe poisoning appear: nausea, vomiting, palpitations, suffocation, redness of the face, panic. The pressure rises. The condition can lead to death.

Levamisole is used with caution with phenytoin and coumarin anticoagulants. It is able to enhance the effects of the listed funds.

You should be careful not to take the medicine with drugs containing:

  • carbon tetrachloride;
  • terachlorethylene;
  • Chenopodium oil;
  • chloroform;
  • ether.

With simultaneous action, the toxic effect on the body may increase.

"Levamisole" is prescribed with caution to patients with impaired renal and liver function. The development of negative reactions is possible due to individual intolerance to the components of the drug.

Analogues of Levamisole

The only analogue of Levamisole containing the same active ingredient is the drug "Dekaris". It is available in two dosages - 50 and 150 mg. 50 mg tablets are intended for children over 3 years of age. They add dye and apricot flavoring.

The drug has the same pharmacological effect as Levamisole. "Dekaris" 50 mg is prescribed to children 3-6 years old for a single dose of half or a whole tablet, depending on the child's weight. From 6 to 10 years old, 1-1.5 tablets are prescribed. At 10-14 years old, a single dose is 75-100 mg (1.5-2 tablets). If indicated, the course is repeated after 7-14 days.

"Dekaris" 150 mg is not prescribed for children under 14 years of age. Adults take 1 tablet once in the evening after meals with a small amount of water. The course is repeated in the same way after 1-2 weeks.

There is no need to go on a fasting diet before taking the drug or take laxatives.

When describing contraindications and side effects, Dekaris indicates the same properties as Levamisole.

Levamisole is better known by its trade name "".

From 1999 to 2003, human treatment with levamisole was suspended in the United States due to the large number of side effects and the availability of alternative less toxic and more effective drugs. However, it is still applicable for treating animals.

Compound

Hydrochloride- this is the active substance of levamisole, is a biologically active derivative of tetramisole - a pale pink or white powder, odorless, highly soluble in water and stable in oxidized solutions. In neutral or alkaline solutions it does not remain unchanged, but begins to decompose. (S)-2,3,5,6-Tetrahydro-5-phenylimidazothiazole hydrochloride is the chemical name of levamisole, the general formula is considered to be C11H12N2S.

Levamisole is available in the form of tablets of 0.05 g or 0.15 g, in the form of a 10% solution for injection - transparent, colorless and odorless, and also in powder form.

Mechanism of action

Since the drug has immunomodulatory properties, the human body increases the production of antibodies to antigens, increases the T-cell response, and the functions of macrophages, monocytes and neutrophils. By killing, levamisole increases immunity.

Pharmacokinetics

Levamisole is quickly absorbed from the digestive organs and further metabolized in the liver. A high level of concentration in the blood is observed 1.5–2 hours after taking the drug. About 70% is excreted through the kidneys within 3-4 days, and half-life is observed after 3-4 hours. Only 5% of the drug leaves the body unchanged.

Medical use

The drug is used to treat diseases caused by both adult individuals and nematodes at an early stage of development.

Used to treat:

  • trichostrongyloidosis;

Levamisole, as having immunomodulatory properties, is used in the treatment of viral hepatitis, Reiter's and Crohn's diseases, rheumatoid arthritis and malignant neoplasms.

Illegal use

In addition to treating humans and animals, Levamisole has found use for narcotic purposes. It is often cut into cocaine and then sold around the world, particularly in the United States. In 2008 and 2009, the US Drug Enforcement Administration found levamisole in 69% of cocaine samples. And in 2011, this figure increased and amounted to 82% of all cocaine samples seized.

This is because the added Levamisole increases the volume and weight of the main drug in powder form, and the powder itself appears purer.

At the same time, after the study, the American newspaper “The Stranger” wrote that levamisole has a stimulating property and allows you to easily pass a street cleanliness test.

The active ingredient levamisole can suppress the production of leukocytes, which will definitely lead to neutropenia and agranulocytosis. A sharp increase in complications associated with the use of cocaine and levomisole simultaneously has been reported. The drug together with the drug increases the risk of the occurrence and development of vasculitis. Two cases of skin necrosis have been reported in patients using cocaine diluted with levamisole. And also two high-profile deaths: the death of Adam Goldstein in 2009 and Andrew Koppel (son of the famous American journalist Ted Koppel) in 2010.

In order to combat the dangerous mixture, special tests began to be distributed that made it possible to most likely identify the impurity of levamisole. Of course, these tests were used by both consumers and dealers themselves.

Levamisole instructions for use for humans

According to the instructions, levamisole is used only internally (orally) with meals. For treating people, the medicine is available in tablet form.

For the treatment of toxoplasmosis, 150 mg of the drug per day is prescribed. Recommended course of treatment: three doses, each with an interval of 1 week.

Levamisole is used once in a dosage of 150 mg for adults, for children - 2.5 mg per 1 kg of weight. If necessary, the dose can be repeated after a week.

It is important to remember that for children there are tablets with a reduced content of the active substance (50 mg), for adults a single dose is 150 mg

For children under 6 years of age, no more than 50 mg of the drug is recommended; from 6 to 14 years of age, 50-100 mg of the drug is acceptable.

Instructions for use for animals

For the treatment of animals, a solution of levamisole 10 is used for intramuscular injection in the following dosages:

  • cattle – 7.5 ml/100 kg (single dosage can be 23 ml);
  • small cattle – 0.75 ml/10 kg (maximum dosage is 4.5 ml);
  • pigs - 0.75 ml/10 kg, if the pig is over 150 kg, then for every extra 50 kg add 3.5 ml of the drug. In case of dosage above 15 ml, intramuscular injection is given in 2-3 different places.

Levamisole 8 solution is used for:

  • ruminants – 7.5 mg per 1 kg of body weight;
  • poultry - 20-35 mg per 1 kg of weight.

The powder is usually mixed with food or water. In case of severe infection, the course is carried out for 3 days, while reducing the single dosage by 2 times.

Levamisole 7.5 in the form of an injection solution is indicated for use in a dosage of 1 ml per 10 kg of animal weight. For cattle, 30 ml is acceptable, for pigs - 20 ml, for goats and large dogs - 4.5 ml.

You should not administer the drug en masse; it is better to test it on several, so that if side effects occur, all animals are not affected.

Side effects

Like every serious drug, levamisole has its own side effects such as:

  • nausea;
  • digestive disorders;
  • abdominal pain;
  • vomiting;
  • ulcers in the mouth.

In addition, cases of pancreatitis have been reported. With long courses of treatment, the following may occur:

  • Convulsions;
  • headache;
  • increased fatigue;
  • ataxia;
  • increased body temperature;
  • the appearance of a rash on the skin;
  • changes in blood tests.

Women may experience uterine bleeding when taking the drug. It is not recommended to use the medicine during pregnancy, since there is no clear information about the effect on the woman’s body and the child herself.

However, there are known cases of negative effects of the drug in pregnant animals.

One of the serious negative effects of taking levamisole is the destruction of leukocytes (white blood cells). According to test results, this occurs in 0.08-5% of patients.

It is known that among the side effects, skin necrosis has been reported in some patients, in which papules can appear on any part of the body.

Animals may also exhibit vomiting, increased agitation, frequency of defecation and urination, and ataxia (impaired coordination of movements).

Contraindications for the use of levamisole

Levamisole is prohibited for the treatment of people with individual intolerance to the components of the drug. Alcohol is strictly contraindicated while taking levamisole, as Antabuse-like syndrome may occur.

Contraindications are renal and liver failure, circulatory disorders in the brain, low levels of hematopoiesis in the bone marrow, and acute leukemia.

Use during pregnancy

No studies have been conducted on the effect of the drug on pregnant women. But tests were conducted on pregnant rabbits and rats, which showed abnormalities in the development of the fetus, so we can conclude that there is no need for lavamisole therapy during pregnancy.

If it is necessary to take the drug, treatment should be carried out under the strict supervision of the attending physician. At the same time, it is necessary to take tests every three weeks.

Interaction with other drugs

Do not take the drug together with medications that reduce white blood cells

In addition, Levamisole has an enhancing anticoagulant effect. Taking it with amphotericin B can cause kidney damage. Together with busulfan, the risk of developing veno-occlusive diseases increases. When paired with any side effects resulting from an overdose are possible. Taking levamisole with warfarin may cause bleeding.
