Azithromycin During Pregnancy: Uses, Benefits, and Concerns

Azithromycin is a widely used antibiotic prescribed for treating bacterial infections in the chest, ear, nose, throat, and other parts of the body. In addition to these common uses, it is sometimes recommended during pregnancy for specific medical conditions. However, its use during pregnancy raises questions about safety, effectiveness, and potential risks.

Why Is Azithromycin Used During Pregnancy?

Azithromycin has excellent oral bioavailability, meaning it is easily absorbed into the bloodstream when taken orally. Additionally, it can cross the placenta, making it useful for treating infections in pregnant women.

Doctors prescribe azithromycin during pregnancy to treat:

• Bacterial infections that could pose risks to both the mother and baby

• Sexually transmitted infections (STIs) such as chlamydia and gonorrhea

• Malaria and toxoplasmosis, which can be dangerous if left untreated

However, despite its benefits, doctors carefully evaluate whether azithromycin is the best option for each patient. Pregnant women should always consult their healthcare provider before taking this medication to ensure it is necessary and safe for their condition.

Role of Azithromycin During Pregnancy and Breastfeeding

As mentioned earlier, azithromycin is often prescribed during pregnancy for infections. However, several antibiotics can treat infections, so it is essential to discuss with your doctor whether azithromycin is the best choice for you. If no safer alternatives are available, and the benefits outweigh the risks, azithromycin may be prescribed.

For breastfeeding mothers, azithromycin can be taken orally if prescribed by a doctor. However, if the baby shows signs of an upset stomach or poor health, the mother should consult her doctor immediately.

Scientific Studies on Azithromycin in Pregnancy

Reducing Maternal Sepsis

Research has shown that a single dose of azithromycin can significantly reduce the risk of maternal sepsis (infection-related complications during and after childbirth). Maternal sepsis is a leading cause of maternal mortality worldwide, contributing to approximately 16% of newborn deaths.

A large-scale study examined the effects of azithromycin on preventing infections during vaginal delivery. In this study:

• 30,000 pregnant women were divided into two groups.

• One group received a single 2-gram dose of azithromycin, while the other group received a placebo.

• The rate of maternal sepsis in the azithromycin group was 1.6%, compared to 2.4% in the placebo group.

• Women who received azithromycin had lower rates of infections such as endometriosis and urinary tract infections (UTIs).

These findings highlight the effectiveness of azithromycin in reducing maternal infections. However, the study also concluded that azithromycin does not significantly reduce the risk of newborn deaths.

Cesarean Deliveries and Azithromycin

For women undergoing cesarean deliveries, studies indicate that azithromycin reduces the risk of postoperative infections. Women who received a dose of azithromycin before surgery had fewer complications and required fewer follow-up medical visits within 42 days of delivery.

Concerns and Controversies

Despite its benefits, azithromycin use during pregnancy is not without controversy. Some researchers suggest that macrolide antibiotics, including azithromycin, may increase the risk of congenital abnormalities and miscarriage. However, there is limited scientific evidence to confirm this claim. More research is needed to determine whether azithromycin poses significant risks to fetal development.

Uncertainty Regarding Birth Defects

There is no clear consensus on whether azithromycin increases the risk of birth defects. Some studies suggest a possible link between macrolide antibiotics and congenital abnormalities, particularly in the gastrointestinal, musculoskeletal, and cardiac systems. However, other studies found no significant correlation between azithromycin use in the first trimester and birth defects.

Compared to erythromycin, another macrolide antibiotic, azithromycin is better tolerated by patients. Many erythromycin users discontinue the medication due to side effects, while azithromycin users report fewer issues.

Possible Side Effects of Azithromycin

Although azithromycin is generally well-tolerated, high doses or prolonged use may cause side effects, including:

• Nausea and vomiting

• Headaches

• Skin rashes

• Dizziness

• Hearing issues (in rare cases)

The Need for Cost-Effective Alternatives

Azithromycin has proven to be effective in reducing maternal infections, especially in vaginal deliveries. However, researchers emphasize the need for cost-effective medications that can prevent both maternal and newborn infections globally.

While azithromycin is widely prescribed, more research is required to determine its long-term safety and effectiveness in pregnancy. Future studies should focus on developing affordable and accessible treatments that reduce the risk of infections in both mothers and newborns.

Azithromycin is a valuable antibiotic with multiple applications in pregnancy, particularly for treating infections and preventing maternal sepsis. While it has been shown to reduce infection-related complications, concerns remain regarding its potential impact on fetal development. Pregnant women should always consult their healthcare provider before taking azithromycin to ensure it is the best and safest option for their condition.
