Cephalexin and Keftab are cephalosporin antibiotics. They are prescribed for bacterial infections of:
- The bones;
- The middle ear;
- The reproductive and urinary systems;
- The respiratory tract;
- The skin;
Because they are effective for only certain types of bacterial infections, before beginning treatment your doctor may
perform tests to identify the organisms causing the infection.
Cephalexin is available in capsules and an oral suspension form for use in children. Keftab, available only in tablet
form, is prescribed exclusively for adults.
If you are allergic to either penicillin or cephalosporin antibiotics in any form, consult your doctor before taking
Cephalexin. There is a possibility that you are allergic to both types of medication and if a reaction occurs, it could be
extremely severe. If you take the drug and feel signs of a reaction, seek medical attention immediately.
Cephalexin belongs to a class of antibiotics called cephalosporins. They are similar to penicillin in action and side
effects. They stop or slow the growth of bacterial cells by preventing bacteria from forming the cell wall that surrounds
each cell. The cell wall protects bacteria from the external environment and keeps the contents of the cell together. Without
a cell wall bacteria are not able to survive. Bacteria that are susceptible to cephalexin include:
- E coli;
- Haemophilus influenzae;
- Staphylococcus aureus;
- Streptococcus pneumoniae;
