Can a pregnant woman take Azinet 500mg?
A person may take Azinet 500mg while breastfeeding but should discuss it with a healthcare professional first. Azithromycin may be safe to use during pregnancy and while breastfeeding. Studies of animals who received very large doses of azithromycin did not find an increased risk of miscarriage or birth defects.
However, there have been no high-quality studies in pregnant humans, so the drug label currently states that “azithromycin should be used during pregnancy only if clearly needed.”
Azinet 500mg can transfer into breast milk and may remain present for 48 hours following a person’s last dose. Although it is generally safe to use when breastfeeding, azithromycin may cause diarrhea, vomiting, or a rash in some babies.
A person should tell a doctor if they are pregnant, might be pregnant, or are breastfeeding before taking azithromycin. If a nursing infant develops side effects while the parent is taking azithromycin, call a doctor for advice.
