What does it treat?
Cephalexin treats certain bacterial infections. It is a cephalosporin antibiotic and does not treat viral colds or flu.
Does it need food?
It can be taken with or without food. Follow the interval on your prescription label.
How should I store mixed liquid?
Keep it refrigerated and discard it after 14 days. Check the discard date written by your pharmacy.
Sources: MedlinePlus cephalexin; cephalexin suspension label.
What if I have a penicillin allergy?
Tell the prescriber and pharmacist exactly what happened and which drug caused it before taking cephalexin. The type and severity of reaction matter. Do not decide it is safe simply because cephalexin has a different name. Previous serious antibiotic reactions need particular attention. Cephalexin label, hypersensitivity
How do I use liquid or handle a missed dose?
Shake the bottle before measuring. Use the pharmacy's marked measuring device. Take a missed dose when remembered unless the next is almost due; then skip it. Do not double. Follow the full prescribed course unless your clinician changes it. MedlinePlus
What side effects need attention?
Severe or bloody diarrhea needs prompt medical advice, even if it starts after the antibiotic course. Face or throat swelling, breathing trouble or a severe skin reaction needs emergency care. Tell your clinician if symptoms worsen or fail to improve. Cephalexin label, warnings and patient counseling
What else should my pharmacist check?
Mention kidney disease and your full medicine list, especially metformin and probenecid. Kidney function can change the dose or schedule that is appropriate. Do not share antibiotics or use someone else's course. Cephalexin label, renal impairment and interactions
