What is Keflex?

Keflex is a first-generation cephalosproin that’s prescribed to treat infections including respiratory tract infections, sinusitis, otitis media, skin and soft tissue infections, an genitourinary infections, to name a few.

Keflex Dosage and Treatment

Make sure to follow the dosage instructions your doctor provides to guarantee the efficacy of Keflex. Strictly abiding by the dosage amount and schedule will help limit the risk of side effects and adverse reactions. Abstain from altering the schedule or from adjusting the dosage yourself. Also make sure to discuss your medical history and background with your doctor to help them accurately assess the ideal dosage for your case.

Keflex dosages vary from person to person, and your doctor may prescribe you a different schedule and amount depending on your unique situation.

The common dosage for Keflex when administered to adults is 250 mg every 6 hours. In some cases, your doctor may opt to let you take 500 mg every 12 hours. The entire treatment period may span from 7 to 14 days.

If your doctor suspects that you have a more severe infection, it’s possible that they might prescribe the medication in larger doses. Typically, severe infections may call for up to 4 grams of Keflex daily, administered in 4 equally divided doses.

For pediatric patients, the dosage of Keflex depends on their body weight. This may vary from 25 to 50 mg per kilogram of body weight, depending on the extent of the infection. For more severe pediatric infections, doctors may prescribe up to 100 mg per kilogram of body weight. Treatment period will also typically span from 7 to 14 days.

For the treatment of β-hemolytic streptococcal infection in pediatric patients, the treatment will usually span 10 days. For the treatment of otitis media in children, doctors will likely prescribe between 75 to 100 mg per body weight.
