Cidofovir Injection Dosage
Cidofovir injection comes as a solution (liquid) to be injected intravenously (into a vein) by a doctor or nurse in a medical facility. It is usually given once every 2 weeks. The length of treatment depends on your body’s response to the medication.
You must take probenecid tablets by mouth with each dose of cidofovir. Take a dose of probenecid 3 hours before receiving cidofovir injection and again 2 and 8 hours after your infusion is completed. Take probenecid with food to reduce nausea and stomach upset. Ask your doctor or pharmacist if you have any questions about how these medications should be taken together.
