This medicine may need to be given for several weeks, depending on how severe your infection is.
Read and carefully follow any Instructions for Use provided with your medicine. Do not use aztreonam if you don't understand all instructions for proper use. Ask your doctor or pharmacist if you have questions.
Prepare your injection only when you are ready to give it. Do not use if the medicine has changed colors, or has particles in it. Call your pharmacist for new medicine.
Aztreonam must be mixed with a liquid (diluent) before using it. When using injections by yourself, be sure you understand how to properly mix and store the medicine. Use only the diluent that your doctor or pharmacist tells you to use.
