Quoting Use of erythromycin in pregnancy

Safety Profile: Erythromycin is classified as a pregnancy category B medication by the U.S. Food and Drug Administration (FDA). This classification indicates that animal studies have not shown any harmful effects on the fetus, and there are no well-controlled studies in pregnant women to establish absolute safety. However, extensive clinical experience with erythromycin use in pregnant women has not demonstrated any significant adverse effects.

Treatment of Bacterial Infections: Erythromycin may be prescribed during pregnancy to treat bacterial infections, such as respiratory tract infections, skin and soft tissue infections, urinary tract infections, and sexually transmitted infections caused by susceptible bacteria. Treating these infections is important to prevent complications that can affect both the mother and the developing fetus.

Alternative to Other Antibiotics: Erythromycin 500 can be an alternative option for pregnant women who have allergies or sensitivities to other antibiotics, such as penicillin. It provides an effective treatment choice when other antibiotics may not be suitable or safe during pregnancy.
