Cephalexin – Helping you ‘Breathe Easy’ & cure Respiratory Tract Infections

Respiratory tract infections (RTI) are classified as infectious diseases of the upper or lower respiratory tract. The common RTI’s include the common cold, laryngitis, tonsillitis, rhinosinusitis and acute otitis media. Cephalexin, a first-generation semisynthetic cephalosporin antibiotic with a wide range of antibacterial activity and clinical applications, is most commonly used to treat such infections.

Cephalexin – from clandestine to ordinary

Cephalexin made it to the World Health Organisation’s List of Essential Medicines after being developed in 1967 and marketed consecutively in the years 1969 and 1970. The Food and Drug Administration (FDA, US) approved the medication on 4th February 1971 (1).

Usually purchased under the brand name drugs Keflex, Cepol and Ceporex, it is sold in the market as a capsule, tablet, and suspension to be consumed orally. Doctors generally prescribe it to be consumed with or without food at intervals between 6 to 12 hours for a duration of 7-14 days, based on the condition that is being treated (2).

The modus operandi of the chemical formula

It works by interfering with the bacterial cell walls. Harmful Bacteria are destroyed to provide relief to the patient. However, it must be borne in mind that this drug only works in the case of bacterial infections and not for viral ailments like the common cold (2).

Common side effects of taking Cephalexin to cure Respiratory Tract Infections

Although this drug’s efficacy is very high, patients might experience some common side-effects. These include diarrhoea, nausea, indigestion, headache, joint pain, extreme fatigue and more (3).

Precautions before consumption

It is advised to avoid consumption of this medicine in the case of the following conditions:

  • If you are known to be allergic to Cephalexin or this family of drugs
  • If you are pregnant or breast-feeding
  • If you are suffering from kidney-related ailments,
  • For children under the age of one.

Wide usage globally

Despite these side effects, the continued popularity and worldwide usage of this drug are based on its proven track record of “broad spectrum” antibacterial activity and excellent safety during approximately 30 years of cumulative clinical experience.

Cephalexin is considered to be the safest medication to treat Respiratory Tract Infection in children and adults. In 2017, 7 million prescriptions in the US made it the ‘102nd’ most common medication administered globally. It was the 5th most common antibiotic used in Canada in 2013. Currently, it has made it to the list of the top 15 commonly prescribed medications in Australia (4).
