Infections that are regarded as minor in nature, and affecting the skin, the genital area and the ear continue to be treated by cephalosporins. Over the ages, various generations this category of antibiotics have been developed; however, the first generation of the antibiotics continues to be used for treating various infections including minor infections.  Cephalexin, the medical name for cephalosporins, remains the bactericidal of choice for treating various conditions as listed in subsequent sections below. Let’s learn more about the possible side effects of Keflex belonging to this category of antibiotics; and reduce undesirable outcomes through the right preventive actions.

Cephalosporins and effectiveness in treating various conditions

Cephalosporin is a prescription only medication, and is available as capsules, tablets, and oral powder suspension. This class of antibiotics is typically recommended for treating specific conditions in children above the age of one year and adults. Keflex, the brand name of this category of medications, is commonly prescribed for treating infections on superficial wounds, that may trigger bacterial infections. Other conditions that can be effectively treated include:

  • Skin infections
  • Ear infections
  • Genital area infections
  • Urinary tract infections
  • Infections in the bone
  • Used as part of combination treatment for Pneumonia
  • Respiratory tract infections

Mechanism of action of Keflex

Keflex works through inhibition of cell wall synthesis, and this delivers the bactericidal effect, that halts the spread of the infection. It is important to note that the bactericidal action is effective only against gram positive bacteria and will not be effective in treating infections attributed to gram negative bacteria. It is also necessary to be aware that bactericidal antibiotics are not to be used for managing viral infections, as the medications will only work to treat or halt bacterial infections. Conditions such as common cold or flu are viral infections and individuals will not experience any relief from this class of medications despite the apparent similarity of the infections.

Impact of dosage on possible side effects of Keflex  

One of the most common reasons for undesirable outcomes in medications is incorrect dosage. Users are likely to attempt heavier dosages in an effort to speed up the healing process, which is a wrong assumption. Patients and caregivers are advised to diligently stick to prescribed dosages, to avoid possible side effects.

Recommended dosages outlined below are intended to help patients with reference information and this is not be regarded as the ideal or actual dosage. Despite the fact that conditions may appear to be similar, actual dosage may differ, and will depend on various conditions – such as the condition being treated, the strength of the medication, the frequency of intake, the duration of the treatment, the use of other medications and other comorbidities or health conditions in the patients.

An average dose anywhere between 1000 to 4000 milligrams is typically recommended for adults and children above the age of 15.

The recommended dosage for children aged above 1 is calculated on the basis of body weight. For every kilogram of body weight, the recommended dosage is between 25 milligrams to 100 milligrams.

  • Blood thinners or other anticoagulants such as warfarin may also end up causing interactions.
  • Probenecid has a mechanism of action that is similar to Keflex and this may cause drug interactions.
  • Cholestyramine when taken along with Keflex may cause drug interactions, including the possibility of increased side effects.

Effects that are relatively harmless and can be ignored
