Aztreonam Dosage

How should I take Aztreonam?

Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

Aztreonam is injected into a muscle or a vein. Aztreonam is usually given in a clinic or hospital setting. The medicine may need to be given for several hours or several weeks, depending on how severe your infection is.

You may be shown how to use injections at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine.

Aztreonam is usually given as long as needed until your infection has cleared or you have been symptom-free for at least 48 hours.

Use aztreonam for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Aztreonam will not treat a viral infection such as the common cold or flu.

Do not give this medication to another person, even if they have the same symptoms you have.

Aztreonam is supplied as a frozen solution in a plastic container. If you use this medicine at home, store the frozen medicine in a freezer. If possible, keep the freezer set at 4 degrees below 0 Fahrenheit or colder.

If you have thawed the medicine at room temperature, you must use it within 48 hours.

Once aztreonam has been thawed, it should be clear and appear colorless or slightly yellow. Do not use the medicine if it has changed color or has particles in it, or if the medicine container leaks. Call your doctor or pharmacist for a new prescription.
