For uncomplicated UTIs, adults typically take 250 mg twice daily for 3 days. Complicated infections may require 500 mg twice daily for 7 to 14 days. Children receive weight-based doses, usually around 15 mg/kg twice daily.
Adults with respiratory infections often take 500 mg twice daily for 7 to 14 days. The dose may be higher for severe infections. Pediatric use depends on the infection severity and patient weight.
Doses range from 500 mg to 750 mg twice daily for adults, typically for 7 to 14 days. Children’s doses are calculated by weight and infection severity.
Adults usually receive Ciprofloxacin doses between 250 mg and 750 mg twice daily, depending on the infection type and severity. For mild infections, lower doses and shorter courses are common. More severe or resistant infections require higher doses and longer treatment periods. Oral tablets are the most common form, but intravenous administration is used in hospital settings or when oral intake is not feasible.
Ciprofloxacin is less commonly prescribed for children but is used when necessary, such as for complicated infections or when other antibiotics are unsuitable. Pediatric doses are weight-based, generally around 15 mg per kilogram twice daily. Treatment duration varies by infection type, but safety and careful monitoring are critical due to potential side effects.
If a dose is missed, take it as soon as you remember unless it is almost time for the next dose. Do not double up to make up for a missed pill. Maintaining a consistent schedule ensures the antibiotic works effectively and reduces the risk of resistance. If unsure, consult your healthcare provider or use telehealth services such as Doctronic.ai for quick advice.
Since Ciprofloxacin is partly eliminated by the kidneys, patients with reduced kidney function may require dose adjustments. Lower doses or extended intervals between doses help prevent drug accumulation and toxicity. Your doctor will determine the best regimen based on kidney function tests.
Although Ciprofloxacin is less dependent on liver metabolism, severe liver impairment may still necessitate caution. Monitoring for side effects and dose adjustments may be advised.
An overdose of Ciprofloxacin can cause symptoms such as nausea, vomiting, dizziness, confusion, and seizures. Immediate medical attention is necessary if an overdose is suspected.
