How long do antibiotics stay in your system?

Dose frequency and therapy regimen depend on how long antibiotics stay in your system. For example, there are drugs that the patient should take every 4 hours and there are those that you can take only once in a few days. The drug in the process of medication intake is concentrated in certain organs. For example, Lincomycin is best accumulated in the bones, so it is more often used in the treatment of inflammatory processes in bone tissues.

Some types of antibiotics act differently. They attach to hematophages (cells of the human immune system). During the inflammatory process immune cells are concentrated in the area of the disease, and these antibiotics are concentrated there together with immune cells.
The doctor determines the compatibility of certain medications first. Medicines that are incompatible with antimicrobial drugs can be prescribed only after antibiotics have been completely eliminated from the body.

Families planning children should take into account the time of complete removal of antibacterial drugs from the body. It is important to understand and remember that a number of antibacterial drugs can adversely affect both the conception process and the health of the child. For example, the antibiotic from tetracyclines group can adversely affect conception 2 months after its administration.

On average, the body needs 6-12 hours to completely remove the antibiotic. However, it should be noted that there are drugs that are withdrawn longer (about 14 days). Washout period depends not only on chemical composition of antibiotic, but also on a number of factors listed below:

  1. Medication form. Injection medicines quickly reach the therapeutic concentration and are removed from the body for 12 hours. Tablets in comparison with injections are removed rather slowly. The elimination period is up to 3 days.
  2. Patient's age. A number of studies have been conducted to determine the time of withdrawal of antibiotics from the body of men and women of different ages. Studies have shown that antibiotics are removed longer in aged people.
  3. Presence or absence of chronic forms of diseases. For example, if a patient has a chronic kidney disease toxins from the body, as well as medicines, will be removed more slowly than a person not suffering from such a disease.
  4. Mode of life, which people adhere to. Doctors and pharmacists agree that after treatment the antibiotic is removed much faster in people who take exercise and have an active lifestyle. Diet is also very important. The use of high-quality and healthy foods has a positive effect on the state of the body and the speed of its purification.

It is impossible to give an unambiguous answer to the questions of how quickly and how many days the body requires for complete purification from medications. Too many factors influence this process. However, if you took the medicine in right dosage and no longer than it was necessary you should not worry because your body will quickly clear itself of the medications taken.
