Flagyl quickly penetrates fetal bloodstream. Experiments on rats have shown that large doses of it (up to five times higher than those usually given to people) don’t harm the fetus. Only in one study after intraperitoneal administration to pregnant laboratory mice in several animals the fetus died, but it’s not entirely clear how this is associated with the use of the drug. However, since the extensive and well-controlled studies of this substance in pregnant women were not conducted, and the results of experiments on animals do not always give a clear picture of how the pills will affect a person, it’s prescribed to pregnant women only in case of urgent need. For example, it’s used to treat trichomoniasis during pregnancy in cases where other drugs have been ineffective.

In breast milk of a woman taking this remedy it’s contained in almost the same concentration as in blood plasma. Therefore, the breastfeeding woman and her doctor will have to make a choice: refuse breastfeeding, or choose another drug.

The exact dose depends on the patient’s diagnosis, general health, and a number of other factors. It’s better to drink a whole glass of water or milk; it can also be taken with meals – plenty of fluids and food can help prevent indigestion. Antibiotics act most effectively if the level of active substances in the body is constant, so it’s very important to take the remedy at regular intervals.

Take the medicine for as long as the doctor said, even if the symptoms of the infection disappear after a couple of days. If you stop taking it too soon, the bacteria can begin to multiply again, which can cause relapse, as well as the development of antibiotic resistance.
Tell your doctor if you don’t notice any improvement a few days after the start of treatment, or if the symptoms of the infection worsen.

How to take?

Since it’s gradually excreted from the body by the kidneys and liver, the patient must take a certain dose every day during the entire treatment period in order to maintain the level of the active substance.

Why you can’t give up the course half way:

The patient feels the first improvement, disturbed symptoms fade away. Thinking that a complete cure has come, the patient believes that the pills can no longer be taken.

Fuel to the fire is poured by the advice of others that it’s not necessary to stuff yourself with any chemistry, since everything is already in order. A huge list of side effects doesn’t add the desire to use antibiotics anymore. But the problem is that not all pathogenic bacteria have been destroyed. Some remained in the form of cysts and other protected forms, as soon as the antibiotic is eliminated from the body, they will again begin to multiply. And this time they will be resistant to the antibiotic they already know.

It seems that the medicine, which should only improve your health, can’t be harmful, but in practice everything is completely different. More and more people suffer from exceeding the permissible dosage of a particular substance, as a result of which the disease not only doesn’t enter the cure stage, but is also complemented by new unpleasant symptoms.

The antibiotic is available in several forms at once, but drug poisoning is associated with exceeding the dosage of tablets when administered orally. Suppositories and other forms of the medicine aren’t able to deliver such a strong blow to the body as tablets, because it’s important to use them with caution.

Due to the fact that the substance quickly spreads to absolutely all body systems, poisoning is a danger to humans. It takes approximately eight hours to remove the decay products of the drug, and during this period the effect may be the most terrible.

  • increased nausea, vomiting and diarrhea;
  • feeling of heaviness;
  • changes in the perception of taste;
  • inflammation of the tongue and gums;
  • regular burp with an unpleasant taste;
  • the appearance of a characteristic plaque in the tongue;
  • significant loss of appetite;
  • with the exacerbation of the disease may develop diseases such as pancreatitis, hepatitis and jaundice.

An overdose of the antibiotic is accompanied by a slight increase in heart rate, which is often difficult to detect on your own. Only a doctor can diagnose this symptom using specialized equipment. At the same time, the patient feels discomfort in the muscles throughout the body and in the extremities.

In order to significantly reduce the effects of poisoning, even if the amount of the substance is exceeded, it’s necessary to give first aid as soon as possible. It’s important to call a team of specialists, since only they can determine the severity of the sickness and prescribe the subsequent medical maintenance of the patient.

You have to wash the stomach with plenty of warm water. In this case, it’s necessary to flush the stomach until its contents are completely out, and the source of infection doesn’t leave the human body.

Next, the patient must take sorbents that block the effect of the toxin on the body and help remove it. For this purpose you can use activated carbon or Smekta, which must be used in full accordance with the prescriptions.

The final stage of patient care is to replenish the water balance in the body.
