Is It Safe To Use Cough Drops During Pregnancy?


A sore throat is one of the many symptoms you experience as your pregnancy progresses. Regardless of what’s causing the soreness and how it feels, you might want to take a cough drop or two for some relief. But how safe are cough drops during pregnancy? Will they affect your or the baby’s health?

Read this MomJunction post to know if you can take cough drops during pregnancy, when to take them and how many you can take to stay safe.


What Are Cough Drops?

Cough drops are medicated candies that dissolve slowly on oral consumption. They offer relief from cough and sore throat caused by common cold and allergies. The medicine lubricates and soothes the throat tissues that are irritated due to cough and cold. They are also referred to as throat lozenges and available as over-the-counter medications (1).

Are Cough Drops Safe During Pregnancy?

Cough drops are usually considered safe when used temporarily, for short-term ailments such as a short-lived cold or sinus inflammation called sinusitis. But, you should avoid overindulgence of these drops and exercise caution to prevent long-term usage. Also, not all medications work the same way for everyone.  Therefore, it is best to consult your doctor before you take them (2).

How Do Cough Drops Work?

The composition of cough drops varies significantly from one brand to another. They contain both active and inactive ingredients that we list next.

Inactive ingredients

Apart from the primary active ingredients mentioned above, cough drops may also contain certain inactive ingredients, which include natural herbs such as:

  • Sage
  • Thyme
  • Wild thyme
  • Horehound
  • Hyssop
  • Mallow
  • Elder
  • Lemon balm
  • Linden flowers

Since there are no specific warnings about the usage of these herbs during pregnancy, their effect on the mom or the baby is not known.

Which Ingredients Are Safe To Use During Pregnancy?

Cough drops containing guaifenesin and dextromethorphan are widely considered safe during pregnancy (10). Menthol drops are also regarded as safe, but there aren’t enough studies to prove they are safe or not during pregnancy (11).

Take cough drops that only help in relieving cough and sore throat. Those containing simple ingredients work better.

The list of popular cough drops that are considered safe for pregnant women are (12) (13):

  • Halls menthol cough suppressant/Oral anesthetic drops
  • Vicks menthol cough suppressant/Oral anesthetic drops
  • Cepacol sore throat and cough drops
  • Chloraseptic sore throat and cough drops

No matter what brand of cough drops you consider taking, it is advisable to check with your doctor before you do.

Which Ingredients Are Unsafe For Pregnant Women?

You should be aware of taking cough drops containing herbal ingredients as most of them are not tested for safety. Also, some include alcohol and should be avoided.

Are There Any Side Effects Of Taking Cough Drops During Pregnancy?

It is natural to reach out for that couch drop or lozenge when you have a cold or a sore throat during pregnancy, but it is important to consider the possible risks of taking it.

  • Suppress mucus production: Mucus is essential for the body to get rid of the germs (14). Cough drops could suppress the formation of mucus (15), trapping the germs within and increasing the chance of infection later.
  • Aggravate sugar levels: If you have gestational diabetes, cough drops will hike the blood sugar levels as many of them have high sugar content (16). Ingredients such as corn syrup and other sweeteners lead to a sudden increase in the sugar levels.
  • Uncertain ingredients: Some herbal ingredients are not safe for consumption, and therefore always check the composition and consult the doctor before you take medicine.

Read on to know more about the precautions you should take before taking cough drops during pregnancy.

Precautions To Consider While Using Cough Drops

Some of the dos and don’ts while taking cough medications are as follows:

  • Read the composition to check if you are allergic to any ingredient.
  • Check the expiry date as the medicine either loses its efficacy or taste or might be outright dangerous for you or baby when expired.
  • Get sugar-free cough drops when you have the risk of gestational diabetes.
  • In the case of severe mucus formation, consider medical advice before choosing any cough drops.

When cough drops are not ideal for you, try the alternatives for relief.

Alternatives To Cough Drops

Sometimes, before trying cough drops, certain alternatives might help. It is better to choose natural remedies over medications to treat cough and sore throat (17).

  • Gargle with salt water (mix 1tsp salt in 8oz of water). It loosens mucus, relieves sore throat, and also kills the bacteria. Do not swallow the salt water because excess salt in drinks or diet may lead to medical conditions like high blood pressure or pre-eclampsia in pregnancy.
  • Drink teas – chamomile tea with honey, ginger tea made of fresh ginger root, lemon and honey tea, and clove tea with honey
  • Homemade chicken soup
  • Suck on a piece of garlic; it helps ease the sore throat and pain
  • Get enough sleep
  • Drink lots of fluids to clear a nasty cold
  • Use a humidifier in your room

When To Call A Doctor?

Refrain from using cough drops, skip home remedies and see a doctor if you are experiencing any of the following conditions:

  • Cough and sore throat that lasts for two or more days
  • The cough does not get better in a week
  • Having a temperature of 101°C or more
  • Having skin rash, nausea, vomiting, headache or swelling

Cough drops may not seem like a big deal or as harmful as other medications taken during pregnancy. But it is best to be careful in keeping yourself and the baby safe. So exercise caution before taking any medication during pregnancy. Talk to your doctor and also be mindful about which cough drops you can take because just anything won’t do.
