Allergies plague many of us every year. In fact, one in five adults suffers from allergies. Allergens are often called hay fever, or seasonal allergic rhinitis, and the most common symptoms are sneezing, stuffiness, a runny nose and itchiness in the mouth, throat, eyes or ears. Allergies often do not stop when women become pregnant the question of whether the use of decongestants are safe during pregnancy is often an unclear answer to many women suffering from allergies.

Most decongestants do not contain enough medication to cause problems with baby, especially if used for short periods. Nasal spray decongestants are even safer since the medication is almost entirely absorbed within the nose and does not travel through the body. As a general rule, physicians advise patients if they can buy it without visiting the pharmacy counter, short-term use will not harm the baby during pregnancy.

Many health care providers recommend using medication that is considered a Category B drug, such as a decongestant or an antihistamine when allergies strike. Category B drugs have been shown through animal testing to not harm an unborn baby when the mother takes the medication during pregnancy.

What If I Take Claritin Before Realizing Im Pregnant


Claritin is a very common over-the-counter medication for allergies, so its quite possible you took it before realizing you were pregnant. Because Claritin doesnt pose a risk for pregnant people, its OK that you did.

If you took Claritin before realizing you were pregnant and experienced the common side effects, you may want to let your OBGYN know this. While Claritin is generally considered safe, every pregnancy is different and every body is different, and those side effects that you couldnt pinpoint before could pose more of a risk later on. Always let your primary healthcare provider know of any medications youre taking, whether over-the-counter or prescription.

Not only have experts said that Claritin is safe while pregnant, but further studies have also confirmed this. A study from 2010 took a closer look at the safety and efficacy of antihistamines during pregnancy and found no issues.

Claritin, which this study refers to as a second-generation antihistamine because it doesnt cause drowsiness, was shown to be safe. The research did acknowledge, though, that at the time there was less data backing this particular drug class as opposed to first-generation antihistamines .

Watch The Pollen Count

Primarily, pollens in the air cause spring allergies. Pollens come primarily from trees and grasses. When pollen grains get into the nose, the immune system mistakenly labels them as foreign and releases antibodies to attack these allergens.

That leads to the release of chemicals called histamines into the blood. Histamines trigger runny noses, itchy eyes and other symptoms.

Avoiding triggers is the first and best option, although it is admittedly difficult. Pollens circulate more on windy days. The higher the pollen count, the more miserable one will be. Many cities publicize daily pollen counts. When counts are high or when it is windy, keep windows and doors closed. If possible, stay inside.

Common Questions About Loratadine

Loratadine is a type of medicine called an antihistamine.

When you come into contact with something you have an allergy to, such as pollen, animal hair or fur, house dust or insect bites, your body produces a chemical called histamine.

Usually, histamine is a useful substance but in an allergic reaction it causes unpleasant symptoms including itchy, watery eyes, running or blocked nose, sneezing and skin rashes.

Loratadine blocks the effects of histamine and so reduces these symptoms.

Loratadine is a non-drowsy antihistamine, so it does not make you feel as sleepy as other medicines like it.

You should start to feel better within an hour.

It depends on why you’re taking it.

You may only need to take loratadine for a short time or as a one-off dose. If you have a reaction to an insect bite, you may only need to take loratadine for a day or two.

You may need to take it for longer if you’re taking it to prevent hay fever symptoms when the pollen count is high.

Talk to your doctor or pharmacist if you’re not sure how long you need to take loratadine for.

Loratadine is unlikely to do you any harm if you take it for a long time. However, it’s best to take it only for as long as you need to.
