  1. loratadine – this is generally the first choice for pregnant women because of the quantity of safety data available for it

While some information suggests that it's significant to avoid every medication while pregnant, Martha Rac, MD, says this is not the case.

"Certain medications, if used properly, can not only make the pregnancy more tolerable but also improve outcomes," says Rac, an assistant professor of obstetrics and gynecology at the Baylor College of Medicine.

One of those medications is Benadryl. "Benadryl is safe during pregnancy and breastfeeding," Rac says.

  1. wear wraparound sunglasses to stop pollen getting into your eyes

"[Benadryl] is a category B medication, which means no evidence of risk in human pregnancies is known," says Rac.

"B" is one of the five categories created by the US Food and Drug istration to classify medications according to the risk they pose to a developing fetus.

While drugs in categories A and B are safe, those in D and X should be avoided.

But most medications drop into the gray area of category C — neither clearly safe nor harmful. In these cases, the benefits may outweigh the risks.

It’s understandable that a lot of women don’t love to take unnecessary medicines when they’re pregnant. No mother-to-be would ever desire to put her baby at an increased risk of a birth defect caused by medication.

However, allergies can make some lady so miserable that medications may be needed just so that allergy symptoms are not taking over their lives.

According to the Food and Drug istration (FDA), no medicines are considered completely safe in pregnancy. This is because no pregnant lady would desire to sign up for a medication safety study while she is pregnant.

Therefore, the FDA has assigned risk categories to medications based on use in pregnancy:

  1. Category A medications are medications in which there are excellent studies in pregnant women showing the safety of the medication to the baby in the first trimester.

    Few medications are in this category and no asthma medications are rated category A.

  2. Category C medications may result in adverse effects on the fetus when studied in pregnant animals, but the benefits of these drugs may outweigh the potential risks in humans.
  3. Category B medications own been studied in pregnant animals, which show that they are relatively safe, but no human studies are available.
  4. Category D medications show clear risk to the fetus, but there may be instances in which the benefits outweigh the risks in humans.
  5. Category X medications show clear evidence of birth defects in animals and/or human studies and should not be used in pregnancy.

Which Medications Are Safe in Pregnancy?


Benadryl can treat more than just allergies

The generic name for Benadryl is diphenhydramine, which is sold under a number of brand names.

You don't need a prescription to get Benadryl or other diphenhydramine-containing medicine as they are over the counter.

Your obstetrician may propose Benadryl if you are pregnant and suffering from: 

  1. allergies
  2. nausea and vomiting
  3. hay fever
  4. sleeping difficulties

Just make certain to follow the instructions and don't exceed the maximum daily dose, Rac adds.

When you're pregnant you can take the same dose of Benadryl as before pregnancy.

For standard Benadryl, that means no more than 1 to 2 tablets every 4 to 6 hours for an adult.

Benadryl is a type of antihistamine, meaning it works by blocking the molecular signal known as histamine. Your body releases histamine when it's suffering from an allergic reaction, which is why Benadryl is often used to treat allergic conditions.


Benadryl does not cause birth defects

Some little older studies suggested that taking Benadryl the first trimester of pregnancy could lead to a slightly higher risk of birth defects.

But larger and more thorough studies own since found no connection between antihistamines and birth defects, Rac says.

For one 2013 study, published in Allergy and Clinical Immunology, researchers examined 20,000 infants — 13,213 with malformations at birth and 6,982 without. They then looked at which mothers used antihistamines in their first trimester and found no significant correlation between that and malformations in newborns.
