Antibiotics are generally used to kill or inhibit the growth of bacteria, so they are used to fight bacterial infections such as pneumonia (pneumonia), urinary tract infections and many others. Each antibiotic group has a particularly good effect on certain bacteria and a less good effect on others. Ceftriaxone is one of the broad spectrum or broad spectrum antibiotics, so it has a good effect against numerous germs. Ceftriaxone can only be used parenterally, i.e. bypassing the gastrointestinal tract, i.e. it cannot be used as a tablet, but only as an infusion via the vein (intravenous = i.v.) or as an injection into the muscle (intramuscular = in the.) are applied.

Side effects

All cephalosporins, including ceftriaxone, can allergic reaction trigger. First and foremost, they show up on the skin through various types of rash (Rash). Also an anaphylactic reaction to the point of anaphylactic shock is possible, this is life threatening. This is a strong overreaction of the Immune systemwhich is divided into several levels. In the beginning you may experience skin reactions such as a rash and Wheal formation show that in the course there is a feeling of heat, swallowing and breathing difficulties (Bronchospasm), nausea, Vomit and diarrhea, in the actual shock there is a significant drop in blood pressure (Hypotension) with a sharp increase in Heart rate (Tachycardia) by widening the vessels up to unconsciousness.

In contrast to allergies, the anaphylactic reaction usually occurs within a few minutes after the drug has been applied. The allergy, on the other hand, can only show itself days to weeks after the first ingestion and develops rather slowly. Furthermore, when using ceftriaxone, reversible changes in the blood count and an increase in liver values ​​can occur, but these usually do not cause any further symptoms and are only noticeable in the laboratory values. Since ceftriaxone can only be administered intravenously, it shows less gastrointestinal side effects (nausea, vomiting, abdominal pain, diarrhea) than other active substances from its group.

With intravenous administration, inflammation of the vein (Thrombophlebitis) occur. At higher doses it can lead to Kidney damage come. In 5-10% of the cases there is a so-called cross allergy to the Penicillins. This means that if a patient cannot tolerate an antibiotic from the group of penicilins and one has to switch to another drug, this allergy can also occur with the administration of ceftriaxone, with a probability of 5-10%. Other possible side effects of Rocephin® are chills, a headache and Fungal infections in the mouth and Pubic area by killing the protective bacterial flora.

Antibiotics from the group of cephalosporins can also trigger a so-called pseudomembranous enterocolitis, inflammation of the bowel. It arises from the fact that the antibiotics inhibit or kill the resident (i.e. normally present) bacterial flora of the intestine and thus leave room for the population with the bacterium Clostridium difficile give. This disease shows up among other things by stomach pain, Diarrhea and fever. If such colitis is diagnosed, the antibiotic must be discontinued and replaced with another one that is effective against the said germs (Metronidazole or Vancomycin). Cephalosporins can rarely cause anemia (anemia) cause.
