Aztreonam Injection Dosage
The dosing guidelines for those using aztreonam injection will be based on a number of factors, such as age, the type of bacterial infection, and kidney function, just to name a few. These injections are given into either a vein or a muscle, and are usually administered every 6 to 12 hours for at least 48 hours.
The dose of aztreonam injection (Azactam®) your healthcare provider recommends will vary, depending on several factors, including:
- Your age
- Your weight (in children)
- The location and severity of the infection being treated
- The bacteria causing the infection
- How well your kidneys are functioning.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Aztreonam injection doses can vary from person to person. Your healthcare provider will choose a dosage for you, based on your individual situation.
The usual recommended dosage of aztreonam injection for treating urinary tract infections is 500 mg or 1000 mg (1 gram) every 8 or 12 hours. For other moderately severe infections, the usual recommended dosage is 1000 mg or 2000 mg (2 grams) every 8 or 12 hours. Doses of 2000 mg every 6 or 8 hours are normally recommended for severe or life-threatening infections.
Aztreonam injections can be given either intravenously (an IV injection) or by injection into a muscle (an IM injection). It is generally recommended that more serious infections and doses greater than 1 gram be given by IV.
Treatment will normally continue for at least 48 hours after the infection has cleared. In some cases, you may need to continue treatment for several weeks, especially if your infection is difficult to completely clear.
Because this medicine may be cleared more slowly from the body in people with kidney disease, your healthcare provider may recommend a lower aztreonam injection dosage if your kidneys are not functioning well. In most cases, people with kidney disease will still receive a regular initial dosage of 500 mg, 1000 mg, or 2000 mg, followed by doses that are about one-fourth to one-half the usual recommended dosage.
