what antibiotics can you take while pregnant | Important Points

Antibiotics are essential in treating bacterial infections, but when you’re pregnant, it can be challenging to determine which ones are safe for you and your growing baby. Some antibiotics can harm a developing fetus, while others are generally safe. If you’re pregnant and need antibiotics, your doctor will prescribe medication that is safe during pregnancy, and you should follow the treatment plan carefully.

Understanding Antibiotics

Antibiotics are drugs that are used to treat bacterial infections. They work by killing and preventing the growth of bacteria, which helps your body fight off the infection. Common infections that require antibiotics include urinary tract infections, respiratory infections, strep throat, and sexually transmitted infections.

Types of Antibiotics

There are several classes of antibiotics, and they each work in different ways to kill bacteria. Penicillins, cephalosporins, macrolides, fluoroquinolones, and tetracyclines are the most commonly used antibiotics. Penicillins are the most widely used antibiotic and are considered safe during pregnancy.

Macrolides, such as azithromycin, clarithromycin, and erythromycin, are often prescribed for respiratory and soft-tissue infections. They are generally safe in pregnancy, but erythromycin may cause some gastrointestinal side effects.

Cephalosporins, such as cephalexin and cefuroxime, are used to treat urinary tract and skin infections. They are safe to use during pregnancy and are often prescribed as a first-line treatment.

Fluoroquinolones like ciprofloxacin and levofloxacin are usually avoided in pregnancy as they have been associated with adverse effects on the developing fetus.

Tetracyclines, such as doxycycline and minocycline, can cause discoloration of the teeth and bones in the fetus. It is therefore avoided in pregnancy.

Antibiotics that are Safe to Take while Pregnant

Penicillins are considered safe during pregnancy and are the most widely used antibiotic. They have been used for over 70 years and have a long-standing safety record. They are the first-line treatment for strep throat, ear infections, and skin infections.

Cephalosporins are also considered safe during pregnancy. They are often prescribed for urinary tract infections and skin infections. Cefixime, cefuroxime, ceftriaxone, and cephalexin are some of the cephalosporins that can be used safely in pregnancy.

Macrolides are also safe during pregnancy. They are often used to treat respiratory infections and soft-tissue infections. However, some macrolides can cause gastrointestinal side effects.

Antibiotics that should be Avoided during Pregnancy

Fluoroquinolones should be avoided during pregnancy. These antibiotics have been associated with adverse effects on the developing fetus. They have been associated with cartilage damage in animal studies, which has led to the avoidance of their use in humans during pregnancy.

Tetracyclines are also avoided during pregnancy. They can cause discoloration of the teeth and bones in the fetus. They have also been associated with inhibition of fetal bone growth, which can lead to skeletal abnormalities.

Sulfonamides like Bactrim should also be avoided, especially in the last trimester of pregnancy. They have been associated with an increased risk of jaundice in newborns.

Potential Side Effects of Antibiotics during Pregnancy

All medications, including antibiotics, have potential side effects. However, the majority of antibiotics are safe when used appropriately during pregnancy. The most common side effects are gastrointestinal, such as nausea, vomiting, and diarrhea.

Some antibiotics can also lead to allergic reactions, which can range from mild to life-threatening. Symptoms of an allergic reaction include hives, itching, swelling, and difficulty breathing.

Many antibiotics may also increase the risk of yeast infections, especially in pregnant women. Yeast infections can cause a thick, white discharge and can be uncomfortable.

Antibiotics and Breastfeeding

Most antibiotics are safe to use while breastfeeding. The majority of antibiotics do not enter breastmilk in significant amounts and do not harm the baby. However, some antibiotics, such as tetracyclines, fluoroquinolones, and sulfonamides, should be avoided while breastfeeding. Your doctor will prescribe antibiotics that are safe to use while breastfeeding.


Antibiotics are essential for treating bacterial infections during pregnancy. However, not all antibiotics are safe for you and your growing baby. It is important to talk to your doctor if you suspect you have an infection while pregnant. Your doctor can prescribe antibiotics that are safe for both you and your baby. Remember to follow the treatment plan and take the medications as prescribed. If you have any concerns regarding the safety of any medications, including antibiotics, don’t hesitate to discuss them with your doctor.
