In fact with rules about pregnancy medications constantly changing, it can feel overwhelming to know what to do when you are feeling sick.

It usually trickles down to weighing the importants for a mother with a health condition — even one as simple as a headache — against potential risks to her developing baby.

As a matter of truth Scientists can’t ethically perform drug testing on a pregnant woman.

It is not accurate to say a medication is 100 percent safe for a pregnant woman (simply because it is never been studied or tested).

In the olden days, medications were assigned to five letter categories based on their level of risk.

Category A was the safest category of drugs to take.

Drugs in Category X were never to be used during pregnancy.

Listed below is a sampling of a few of the drugs that we know pregnant women should avoid.


Antibiotics are often linked to adverse reactions in pregnant women.

1. Chloramphenicol

Chloramphenicol is an antibiotic that is usually given as an injection.

For your information this drug can cause serious blood disorders and gray baby syndrome.

2. Ciprofloxacin (Cipro) and levofloxacin

Ciprofloxacin (Cipro) and levofloxacin are also types of antibiotics.

These drugs could cause problems with the baby’s muscle and skeletal growth as well as joint pain and potential nerve damage in the mother.

3 Ciprofloxacin and levofloxacin are both fluoroquinolone antibiotics.

Fluoroquinolones can increase the risk of aortic tears or ruptures.

This can result in life-threatening bleeding.

Persons with a history of aneurysms or certain heart diseases may be at an increased risk of side effects.

4. Fluoroquinolones may also increase the chances of having a miscarriage, according to a 2017 study.

5. Primaquine

Primaquine is a drug that is used to treat malaria.

There is not a lot of data on humans who have taken this drug during pregnancy, but animal studies suggest it is harmful to developing fetuses. It can damage blood cells in a fetus.

6. Sulfonamides

Sulfonamides are a group of antibiotic medications. They’re also known as sulfa drugs.

The majority of these types of drugs are used to kill germs and treat bacterial infections. They can cause jaundice in newborns.

Sulfonamides may also increase the chances of having a miscarriage.

7.Trimethoprim (Primsol)

Trimethoprim (Primsol) is a type of antibiotic. When taken during pregnancy, this drug can cause great neural tube defects.

These defects affect brain development in a developing baby.

8. Codeine

Codeine is a prescription drug used to relieve pain. In some states, codeine can be purchased without a prescription as a cough medicine.

The drug has the potential to become habit-forming. It can lead to withdrawal symptoms in newborns.

9. Ibuprofen (Advil, Motrin)

High doses of this OTC pain reliever can cause many serious problems, including:

delayed onset of labor
premature closing of the fetal ductus arteriosus, an important artery
hemorrhaging for both mother and baby
necrotizing enterocolitis, or damage to the lining of the intestines
oligohydramnios, or low levels of amniotic fluid
fetal kernicterus, a type of brain damage
abnormal vitamin K levels

Many experts agree that ibuprofen is probably safe to use in small to moderate doses in early pregnancy.

It is especially important to avoid ibuprofen during the third trimester of pregnancy, however.

During this period of pregnancy, ibuprofen is more likely to cause heart defects in a developing baby.

10. Warfarin (Coumadin)

Warfarin (Coumadin) is a blood thinner that’s used to treat blood clots as well as prevent them. It can cause birth defects.

It should be avoided during pregnancy unless the risk of a blood clot is more dangerous than the risk of harm to the baby.

Thank you so much for your time.
