Can Certain Medications Affect my Cervical Mucus?

What is cervical mucus?

Cervical Mucus plays a very important part in conception, although many people do not recognize just how important it is. Cervical Mucus is a fluid like substance produced by a woman’s body during her monthly cycle. During a woman’s ovulation period, cervical mucus is at it’s prime.  Claim Your 20 Free Pregnancy Tests – Click Here

This is because cervical mucus plays an important role in helping the sperm get to the egg quickly and easily. Cervical mucus gives the sperm something to grab onto during its journey to the egg.

However, certain medications can affect a woman’s cervical mucus, making it harder for her to get pregnant. Today we are going to go over a few of the medications that can affect cervical mucus.


Guaifenesin is the active ingredient found in many cough syrups such as Robitussin. It is one of the few medications that can actually improve the quality of a woman’s cervical mucus. It can be helpful in creating egg white cervical mucus, which is the optimal cervical mucus for conception.

Many women swear by taking Robitussin or other cough syrups with Guaifenesin as the active ingredient so that they can improve the quality of their cervical mucus. However, check with your doctor before using this method just to make sure it is okay with him or her.


Clomid is known to boost ovulation and make it easier for women to get pregnant. However, most women don’t realize that Clomid can also have a negative effect on cervical mucus. Clomid can really do a number on cervical mucus, and can even help to create hostile cervical mucus.

Hostile cervical mucus can make it hard for a woman to get pregnant. Sometimes, Clomid can even prevent you from producing cervical mucus at all, which is a bad thing if you are trying to get pregnant.

Allergy medicines

Allergy medications that contain antihistamines can also have a negative effect on cervical mucus. Keep in mind that anything that is made to dry up mucus, will also dry up cervical fluid.

Studies have shown that many antihistamines can thicken and decrease the amount of cervical mucus that a woman’s body produces. Ask your doctor before taking any allergy medications if you are trying to conceive.

Other medicines

There are also other medications like antidepressants, antispasmodics, as well as estrogen and progesterone can affect your cervical fluid. The best course of action is to just simply ask your doctor if the medication you are taking will have any affect on your cervical fluid. Your doctor will be able to tell you for sure and can help you choose an alternate medication if you need to.
