Adults typically take 250 mg to 500 mg twice daily for 3 to 14 days, depending on infection severity. For uncomplicated UTIs, a shorter course is common, while complicated infections may require longer treatment.
Doses usually range from 500 mg to 750 mg twice daily for 7 to 14 days. This includes infections like bronchitis and pneumonia caused by susceptible bacteria.
For skin infections, the dose is often 500 mg twice daily for 7 to 14 days. Duration and dose may vary based on infection depth and patient response.
In cases of inhalational anthrax exposure, adults may be prescribed 500 mg twice daily for 60 days as a preventive measure.
Adults generally take Cipro tablets orally twice a day. The dose typically ranges from 250 mg to 750 mg, depending on the infection being treated. For serious infections, higher doses and longer treatment durations are common.
It’s important to follow the prescribing doctor’s instructions carefully. Stopping treatment early or missing doses can lead to antibiotic resistance or incomplete clearance of the infection.
Ciprofloxacin is used in children only when necessary and under strict medical supervision. The dose is calculated based on body weight, usually 10 to 20 mg per kilogram per dose, given twice daily.
Because of potential side effects and concerns about cartilage development, pediatric use is limited to cases of serious infections in which the benefits outweigh the risks.
If a dose is missed, take it as soon as you remember. If it’s near the time for the next dose, skip the missed one and continue as scheduled. Do not double the dose to catch up. Consistency in dosing helps maintain effective drug levels in the body.
Patients with reduced kidney function may require dose adjustments to avoid drug accumulation and toxicity. Doctors often reduce the frequency or dose based on kidney test results.
While ciprofloxacin is primarily excreted by the kidneys, severe liver disease may affect metabolism. Dose changes are less common but should be monitored by a healthcare professional.
Taking too much ciprofloxacin can cause serious side effects, including seizures, dizziness, and heart rhythm problems. If an overdose is suspected, seek emergency medical help immediately.
Warnings include potential tendon rupture, nerve damage, and sensitivity to sunlight. Avoid strenuous exercise and prolonged sun exposure during treatment.
Take ciprofloxacin at least 2 hours before or 6 hours after consuming dairy products or calcium-fortified juices to improve absorption.
Drink plenty of fluids to prevent crystalluria and kidney issues.
Complete the full course even if symptoms improve early.
Inform your doctor about all medications and supplements to avoid interactions.
