They are also used to treat dental infections.

How to take Cefalexin capsule

The doctor will decide on the most appropriate dose for you, based on the nature and severity of your infection. The label will tell you how many capsules you need to take as well as how often to take them.

Swallow the capsule whole with water.

Adults: The usual dose is 500mg every 8 hours, although your doctor may tell you to take 1g to 4g a day, split up into smaller doses.

Elderly: You should take the normal adult dose, unless you have severe kidney problems, when the maximum daily dose will be 500mg.

Children over 5 years: Your doctor will calculate the correct dose, depending on the child’s weight. The usual daily dose is 25mg to 50mg for each kilogram of their weight and is usually split up into smaller amounts taken every 8 or 12 hours. If your child is taking Cefalexin capsules for ear infections, he or she may have to take 75mg to 100mg for each kilogram of their weight, split up into smaller doses throughout the day.


This medicine is not recommended for use in children under 5 years of age.
