Navigating your child’s health can be tough, especially when they’re sick. If your pediatrician, Anita Sabeti, has prescribed cephalexin, an antibiotic, it’s essential that you understand the correct dosage and how to administer the medication safely.
This guide provides a comprehensive overview for parents, but always remember to follow your doctor’s specific instructions.
What Is Cephalexin?
Cephalexin is a powerful antibiotic belonging to a class of drugs called cephalosporins. It works by killing bacteria or preventing their growth, effectively treating common infections such as:
- Ear infections (Otitis Media)
- Strep throat (Pharyngitis)
- Skin and soft tissue infections
- Urinary tract infections
It’s important to remember that cephalexin is not effective against viral infections like the common cold or the flu. For this reason, a doctor will only prescribe it for bacterial infections.
Understanding Pediatric Dosage
A doctor carefully calculates cephalexin dosage for children based on their body weight. This ensures they receive an effective amount of medication without the risk of an overdose.
General Dosage Guidelines
For mild to moderate infections, the typical dosage is 25 to 50 mg per kilogram (kg) of body weight per day. Doctors usually give this in equally divided doses, either every 6 or every 12 hours. However, in more serious cases, your doctor may increase the dosage to 50 to 100 mg/kg per day, also divided into multiple doses.
Example
For instance, a 20 kg child with a mild infection might receive a daily dose of 500 mg (25 mg/kg x 20 kg). You could then split this into a 250 mg oral dose every 12 hours.
Pediatric Dosage Reference Chart
The following chart provides general dosage guidelines based on the type of infection. Therefore, your doctor will provide the exact dosage for your child.
