Use in pregnancy

  • Aztreonam should be used in pregnant patients only if the benefits outweigh the potential risks. There have been no adequate, well-controlled studies of aztreonam in pregnant women, and data on aztreonam use during pregnancy are insufficient to inform a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes

It is generally well tolerated, but like all medications, it can cause adverse reactions and should be used with caution in certain populations, such as pregnant women and those with a history of bronchospasm.
