Cephalexin
About Cephalexin
Cephalexin belongs to the group of antibiotics called cephalosporin used to treat various bacterial infections of the nose, lungs, ear, bones, joints, skin, urinary tract, prostate gland, and reproductive system. Besides this, Cephalexin is also used to treat dental infections. Bacterial infections are caused due to the multiplication of harmful bacteria inside or on the body. Infectious or harmful bacteria can make you sick and reproduce quickly in your body. These harmful bacteria produce chemicals known as toxins, which can damage tissue and make you sick. Cephalexin does not work against infections caused by the virus, including cold and flu.
Cephalexin is bactericidal in nature. Cephalexin works by blocking enzymes responsible for making peptidoglycan, an important component of the bacterial cell wall. Thus, it kills the bacteria and helps in treating and preventing the spread of infections.
The dose and duration of Cephalexin can vary depending on your condition and the severity of the infection. Also, it is recommended to complete the course of medicine even if you feel better as it is an antibiotic. Leaving it in between may lead to even severe infection that will, in fact, stop responding to the antibiotic (antibiotic resistance). In some cases, you may experience certain common side effects, such as diarrhoea, nausea, vomiting, indigestion, stomach pain, and skin rashes. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Before starting Cephalexin, please inform your doctor if you have any allergy (against any antibiotic), kidney or liver problems. Do not take Cephalexin on your own, as self-medication may lead to antibiotic resistance in which antibiotics fail to act against specific bacterial infections. Avoid taking Cephalexin if you are pregnant or breastfeeding unless prescribed by a doctor. Cephalexin should not be given to children below 5 years. Cephalexin may affect certain laboratory test results, such as blood tests for liver function, glucose tests, and Coombs tests. Inform the person doing the tests that you are taking Cephalexin.
