How should cephalexin be used?

Cephalexin is available in the following forms:

  • Oral tablet or capsule
  • Oral suspension (liquid)

The recommended dosage of cephalexin may vary depending on the individual's condition and response to treatment. Your healthcare provider will determine the appropriate dosage and administration instructions. Take the medication exactly as prescribed, and inform your doctor if you begin to experience any side effects while taking the medication.

Cephalexin can be taken with or without food.

Cephalexin should be taken with a glass of water at the same time every day. Do not crush or chew cephalexin capsules or tablets.

If you are taking liquid cephalexin, use a dosing spoon or measuring cup to measure the medicine. Do not use a household spoon to estimate the amount of medication to use.

What should I do if I miss a dose?

If you miss a dose, take it as soon as you remember it. If it's almost time for another dose of cephalexin, skip the missed dose and take your next dose as scheduled. Do not take or apply a double dose of cephalexin.

What do I do if I'm feeling better?

Do not discontinue or alter your cephalexin dosage without consulting with your healthcare provider. Follow your healthcare provider's instructions regarding dosing and other recommendations for taking cephalexin.

How should I store cephalexin?

Store cephalexin as directed by your healthcare provider or pharmacist. Proper storage is essential to maintain the medication's effectiveness. Cephalexin should be stored at room temperature, away from excessive heat, light, and moisture.

Keep the medication out of the reach of children and ensure that the container is tightly closed.
