Some of the factors affecting your dosage of Fortaz include how much you weigh and how well your kidneys are functioning. The "standard" amount varies widely -- it ranges from 500 mg to 2 grams (2000 mg) every 8 to 12 hours. You will probably continue to receive Fortaz for a few days after your infection has cleared up, or even longer in more serious cases.
An Introduction to Dosing With FortazThe dosage of Fortaz® (ceftazidime) your healthcare provider recommends will vary, depending on factors such as:
- Your age
- Your weight
- How well your kidneys are functioning
- Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically tells you to do so.
The standard recommended dose for Fortaz varies widely depending on several factors, but usual dosages for adults typically range from 500 mg to 2 grams (2000 mg) every 8 or 12 hours. In general, the more serious the infection, the higher and more frequent the dose. Although Fortaz can be injected into a muscle (intramuscularly) or given intravenously (by IV), the IV route is usually best when treating serious infections.
For children, the dosage is calculated based on the child's weight. Fortaz is approved for use in young children, even newborns. It should be given by IV, not intramuscularly, for children age 12 years and younger. Typical doses in children range from 30 to 50 mg per kg (about 13 to 23 mg per pound) every 8 or 12 hours.
If your kidneys are not functioning well, your healthcare provider may recommend a lower or less frequent Fortaz dose.
