What allergy medicines are safe while pregnant

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 study, published in Allergy and Clinical Immunology, researchers examined 20, infants &#x; 13, with malformations at birth and 6, without. They then looked at which mothers used antihistamines in their first trimester and found no significant correlation between that and malformations in newborns.

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. hay fever
  3. nausea and vomiting
  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.

Avoid certain allergy medicine while pregnant

There are a number of medications that are not safe to take during pregnancy. First among them are oral decongestants.

Oral decongestants are best avoided altogether during the first trimester because of an uncertain risk of several rare birth defects,” says Ciara Staunton, a family nurse practitioner and owner of Staunton Primary Care in Cincinnati.

“However, Sudafed (pseudoephedrine), which is locked up behind the pharmacy counter, can be used in the second and third trimesters in women without hypertension.”

But Staunton warns that Sudafed-PE (phenylephrine), the over-the-counter option, should never be taken during pregnancy. It is less effective than pseudoephedrine. But more importantly, its safety for pregnant women is questionable.

Ms. Staunton also recommends against using any herbal therapies during pregnancy.

“In the United States and most other countries, herbal medicines are minimally regulated and not monitored for adverse events.”

How to tell shich medications are safe during pregnancy

"[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 &#x; neither clearly safe nor harmful.

In these cases, the benefits may outweigh the risks. "This should be a conversation between you and your obstetrician," she says.

Antihistamine tablets (oral antihistamines)

Antihistamine tablets can assist relieve itchy eyes, a runny nose and sneezing, but not every types are suitable to take during pregnancy, so always check with a GP beforehand.

Pharmacists are unlikely to sell antihistamines without a prescription for use in pregnancy because of manufacturers’ restrictions.

If you cannot use nasal sprays or eyedrops or they do not work for you, a GP may recommend an antihistamine tablet that does not cause drowsiness, such as:

  1. loratadine – this is generally the first choice for pregnant women because of the quantity of safety data available for it
  2. cetirizine – if loratadine is not suitable or does not work for you, a GP may recommend cetirizine, another antihistamine tablet that does not cause drowsiness

Chlorphenamine is also considered one of the safer antihistamines to take during pregnancy, but because it can cause drowsiness, loratadine and cetirizine are generally the preferred options.

More than 50 million Americans suffer from allergies each year, according to the Centers for Disease Control and Prevention (CDC).

In fact, allergies are the sixth leading cause of chronic illness in the U.S.

What’s more, pregnancy can sometimes make allergy symptoms worse. Every woman’s body is diverse, and every pregnancy is diverse, so it’s impossible to predict exactly how allergies will affect an individual pregnant woman.

But in general, pregnant women may experience some of the following symptoms differently from other allergy sufferers:

  1. Pregnancy hormones might cause the inner lining of your nose to swell. This causes nasal congestion and a runny nose.
  2. This enhanced congestion makes seasonal allergy symptoms worse.
  3. Severe congestion could lead to poor stress and poor sleep quality.

If you’re expecting and suffering from symptoms love these, here’s what you need to know about taking allergy medicine while pregnant.
