Ticarcillin and Clavulanate is a prescription used for the treatment of certain bacterial infections such as:

  • Bacterial infections of the lower respiratory tract,
  • Bones or joints, 
  • Inside the abdomen,
  • Skin and soft tissue,
  • Kidney, 
  • Or after surgery 

Bacterial infections are common and their effects vary. Several different bacteria can cause illness. Bacteria are small organisms that can invade the body that causes illness. These infections usually trigger a protective immune response. Children and adults of any age can develop a bacterial infection. It can infect any area of the body. A bacterial infection can spread throughout the blood as well. Bacterial infections are caused by the transmission of bacteria. You can be exposed to bacteria from other people, through the environment, or from eating contaminated food or drinking contaminated water. Some general symptoms of a bacterial infection include:

  • Fever
  • Swollen lymph nodes in the neck, armpits, or groin
  • Feeling tired or fatigued
  • Headache
  • Vomiting
  • Nausea 

Bacteria are relatively complex, single-celled creatures, many with a rigid wall, and a thin, rubbery membrane surrounding the fluid inside the cell. They can reproduce on their own. Most bacteria are harmless and some help by digesting food, fighting cancer cells, destroying disease-causing microbes, and providing essential nutrients. Bacterial infections can be highly contagious and so you need to take special care to avoid spreading infections by washing hands, covering up when coughing and sneezing or not sharing cups and drink bottles.

Ticarcillin is a penicillin-type antibiotic and Clavulanate is a medicine that prevents bacteria from inactivating the Ticarcillin. The Food and Drug Administration (FDA) has already approved this prescription. 

How does Ticarcillin/Clavulanate work?

Ticarcillin works by interfering with the ability of bacteria to form cell walls. The cell walls of bacteria are vital for their survival. They keep unwanted substances from entering their cells and stop the contents of their cells from leaking out. Ticarcillin impairs the bonds that hold the bacterial cell wall together. This allows holes to appear in the cell walls and kills the bacteria.

Clavulanate inhibits the action of the beta-lactamases produced by certain bacteria. It prevents these bacteria from inactivating the Ticarcillin and leaves the bacteria susceptible to attack. Clavulanate, therefore, increases the range of bacteria that Ticarcillin can kill.

Certain bacteria are resistant to penicillin-type antibiotics. It is because they have developed the ability to produce defensive chemicals called beta-lactamases. These interfere with the structure of penicillin-type antibiotics and stop them from working.

Do not self-inject this if you don’t understand how to give the injection properly dispose of used needles, IV tubing, and other items used to inject this medication.
