Cephalosporins are a group of antibiotics used to treat and manage certain types of bacterial infections. They belong to a class of medication called beta-lactams. All cephalosporins act directly on bacteria, killing them off. They are classified into 5 generations based on the time they were developed. Each category is effective against certain kinds of bacteria. Those of the first generation are used to treat mild bacterial infections while the fifth generations are very effective against severe bacterial infections. Cephalosporin is the generic name for this group of medication and is available in various brands. Some common brand names include Cephalexin, Cefdinir, Cefaclor, Cefazolin, etc. Cephalosporins may come in liquid, tablet or capsule forms. Injectable ones are also available, to be administered by health care professionals which is a health priority.

Cephalosporins Uses

Cephalosporins are used to treat a wide range of bacterial infections including infections of the bone, ear, skin, kidney and throat, meningitis, urinary tract infections, sexually transmitted diseases among others. They work by fighting the bacteria in the body directly, by interfering with the build up of bacterial cell wall. They are not used to treat viral infection or flu. The five generations of cephalosporins act specifically on certain types of bacteria. Though these antibiotics were invented several years ago, improved ones are constantly being produced. The first generation cephalosporins are the simplest ones, acting only on the least resistant bacterial pathogens. With constant improvement through scientific research, second then third, fourth and fifth generations of these antibiotics were made. The ones belonging to the fifth generation are very effective against serious bacterial pathogens.

Consult your doctor before using any form of cephalosporin. Make sure you undergo a test to accurately determine the type of infection you have before using any type of this medication. Your doctor will recommend any brand that is best for you. Tell your doctor about any health issue you have or any major sickness you have previously experienced. Do not use cephalosporin if you have any of the following medical conditions:

  • Kidney problems
  • Stomach pains
  • Liver problems
  • Intestinal problems
  • Severe allergic reactions to penicillin

Once you commence treatment with cephalosporin, make sure to complete your medication. You may feel better after some doses but continue taking your drug until your medication is complete. If you stop before time, you may suffer the infection all over again. This time the symptoms may reoccur more vigorously and may be very difficult to treat. Bacterial infections are very adaptive to antibiotics. A relapse may not be effectively treated with the previous cephalosporin you were using. You may have to switch to a higher generation antibiotics as they are generally more effective against. Make sure to check any type of cephalosporin you are about to use. Check for any form of discoloration or particles. If present, do not use the drug.
