Tablets for round and tapeworms

After taking the drug it is possible side effects in the form of dysfunction of the digestive organs, nervous system and genitourinary organs.

This is one of the most modern anthelmintic drugs, effective against round and tapeworms, as well as Giardia. 1-2 tablets are enough to cure. During therapy, blood counts need to be monitored. The medicine can be taken by adults and children over 2 years of age. Nemozol is contraindicated during pregnancy.

Treatment methods for trematodes

A drug such as Biltricid fights flukes. Good effect provided by Azinox. They contain praziquantel, which causes paralysis of the body of helminths and leads to their death.

Sometimes antibiotics are prescribed. Vitamins and mineral supplements are used to strengthen the immune system. Not everyone knows how to deal with intestinal flukes. After the main course of therapy it is required recovery stage. Its goal is to normalize the intestinal microflora. Eubiotics are prescribed (Linex).

Means for the treatment of protozoa

It is possible to use the medicine to treat young children. During therapy you should not drink alcohol. Long-term use of metronidazole may lead to changes in the blood. When Giardia is detected in a person’s body, drugs of the nitrofuran group are often prescribed. In case of defeat biliary tract Prokinetics and cholekinetics can be used.

The most effective drugs are tinidazole and metronidazole. It is preferable to use medications in gel form. Alcohol and ether talkers have a good effect. It is recommended to combine drug therapy With cosmetic procedures for skin cleansing. Electrophoresis with moisturizers is often used.

Non-hardware facial cleansing can be performed. During the remission phase, microdermabrasion is performed. To prevent recurrence of demodicosis, peeling is performed. After the main course of treatment, laser coagulation is recommended. To get rid of mites on your face, you need to give up decorative cosmetics during therapy.

Some people develop demodicosis of the eye. Drops are prescribed. An important aspect of therapy is proper care for the skin. The face should be wiped with disposable wipes, clothes should be washed frequently and changed every day. bed dress. It is recommended to sleep on synthetic padding rather than feather pillows.

Anti-pediculosis drugs are used in the form of creams and shampoos. If body lice are detected, all clothing must be treated. When a person develops dermatitis, anti-inflammatory and healing ointments are used. It is imperative to take proper care of your hair. Lice can be combed out using a fine comb.

Sanitary and hygienic measures

They have great importance in the treatment of enterobiasis. Pinworms are easily transmitted from a sick person to a healthy person, and the carrier himself poses a danger to others.

In parallel with taking medications, the following measures must be observed:

  • cut your nails short;
  • exclude contact with patients;
  • wear swimming trunks;
  • take a shower every day;
  • change linen frequently;
  • wash your hands before eating and after using the toilet.

  • sagebrush;
  • propolis;
  • tansy flowers;
  • ginger root;
  • coriander;
  • a collection based on oak bark, buckthorn bark and wormwood;

In the treatment of demodicosis folk remedies you can use a decoction based on wormwood, oak bark, Castor oil, celandine and aloe juice. In the treatment of pediculosis in children they are used herbal remedies, rich essential oils. These include basil, geranium, anise and rosemary.

When Giardia is detected, a tincture based on horseradish, a mixture based on plantain and honey, as well as a decoction of flax seeds and cloves are effective.

Surgical methods of treatment

Small abscesses are punctured and the fluid is removed. Severe intestinal damage by amoebas may require resection or colostomy. Echinococci pose a danger to humans.

The last option of the operation is dangerous due to the possible spread of echinococcus larvae. Abdomen process antiseptic solutions. Surgery for helminthiasis is also required when there is a massive invasion of the body.
