What Medicines To Avoid When Pregnant

Last Updated on



Pregnancy is a complicated time: the impending joy of having a child is marred by several complications. Pregnant women are especially susceptible to heachaches, stomach problems, back pain, and so on. However, care must be taken that you do not blindly consume over the counter (OTC) medication based on the word of the pharmacist. While most OTC drugs are perfectly safe, there are some which are known to increase the risks to your foetus. It is important to note that this article is meant to tell you that exercising caution for these nine months is of utmost importance. Please do not follow our recommendations before checking with your physician.





List of Drugs Better Avoided in Pregnancy

There are few medications to avoid during pregnancy as they might impact the health of your foetus. Some of them are:

1. Antifungal Drugs

Vaginal yeast infections are common occurrence during pregnancy. However, please do not medicate yourself with the usual Fluconazole tablets that are prescribed for oral thrush and other fungal infections. This is because the preparation of these drugs includes certain ingredients that could seep into the umbilical cord blood through the placenta, negatively impacting the development of your foetus. Contact your gynaecologist to handle the situation.




2. Antihistamines

Antihistamines are basically allergy medications which are given to control symptoms such as rash, breathing impairment and uncontrollable sneezing. Certain types of antihistamines contain active ingredients that could result in extreme reactions, especially in the third trimester. Additionally, antihistamines cause dryness, fainting and fatigue in pregnant women. If you suffer from hayfever or other allergies, consider alternatives such as ensuring clean and hygienic surroundings, breathing exercises and even salt water nasal sprays.

3. Herbal Remedies

Herbs offer a plethora of medicinal benefits, even for pregnant women. Although, some herbs are not recommended as they can have serious effects, leading to miscarriage, stillbirth or developmental defects in the foetus. A few of these herbs include liquorice, rosemary, ginseng, wormwood, cinnamon, ephedra, yarrow, cohosh and so on. Do your research before employing herbal remedies.





4. Antibiotics

Antibiotics are indispensable against infections, but pregnant women should avoid certain kinds during the second and third trimesters. Several studies have shown that taking tetracycline and streptomycin could stain and discolour your baby’s milk teeth and even severely impact their bone growth.

5. Substance Abuse

Consuming illegal drugs is an all-round bad idea to do when you are pregnant. Methamphetamines and marijuana are believed to cause heart problems in your growing foetus, as well as result in premature labour or miscarriage. This could also apply to prescription medications that have the potential for addiction, such as codeine, ritalin, and xanax.

6. Aspirin

Probably the most commonly used drug for headaches, aspirin can cause very dangerous health defects in pregnant women, leading to conditions such as miscarriage, placental tearing and stillbirth, especially in the first trimester. Consider ibuprofen in this same category, and avoid both these meds until your child is born.

7. Morning Sickness Medications

If you are suffering from morning sickness, and you certainly will, consulting your doctor is a far better option than taking OTC drugs like pyridoxine or ginger pills. These substances are believed to cause miscarriages if consumed in high doses.





8. Nasal Decongestants

These meds are very helpful in dealing with stuffy noses and itchy, watery eyes, symptoms which you will experience considerably more during pregnancy. These treatments are not recommended, however, as they tend to cause other symptoms such as nausea, migraines and sleeplessness, which will put further stress on your body. Instead, employ steam inhalation methods to obtain relief from your blocked respiratory tract.

9. Travel Immunisations

Vaccinations are compulsorily offered to travellers going to areas with high incidences of malaria and yellow fever, but some doctors consider them dangerous to foetal health. However, in most instances you will receive the vaccine as the risks associated with these diseases outweigh the risks to your pregnancy.




10. Tranquilisers

Chlordiazepoxide and diazepam are commonly used to treat mood disorders that cause anxiety, panic attacks and insomnia, providing a calming effect on the patient. But they can be very addictive, and might even cause withdrawal symptoms in your unborn child.

11. Anticonvulsant Drugs

These drugs, such as Clonazepam, are similar to tranquilisers. They are usually prescribed to control involuntary body movements in conditions such as seizures. However, there has been sufficient research linking them with premature birth and miscarriage, so avoiding them is a safe bet.





12. Psychiatric Medications

If you suffer from psychiatric conditions such as bipolar disorder, ADHD, PTSD and so on there is all the more reason for you to avoid OTC medications, as a few contain compounds such as paroxetine which lead to developmental impairments in the foetus, especially during early pregnancy.

13. MAO Inhibitors

These are active ingredients in many antidepressant drugs, such as Isocarboxazid and Phenelzine. They might cause irritability and withdrawal symptoms in your new born. Pregnant women have an increased risk of experiencing the symptoms of depression, but you should let your therapist decide how to handle the situation.




14. Acne Drugs

Acne can occur at any time, but more so when hormones are running amok in your body. While most acne treatments are fine, such as benzoyl peroxide and clindamycin, there are several that can cause serious defects in the unborn foetus. For example, vitamin A derivative drugs like Isotretinoin and Retino-AC are teratogenic, that is they result in heart, brain and skeletal abnormalities in the baby. Try natural methods of clearing acne such as turmeric paste, curds, and aloe vera. Staying hydrated will help keep your skin glowing.

Important Points to Remember

Here are some tips for you to deal with the various symptoms and discomforts that occur during pregnancy without resorting to pharmaceuticals.





Talk To Your Doctor

1. Talk to your Doctor

This should be the first thing you do if you require medications during your pregnancy. Your gynaecologist will know exactly what drugs are dangerous for pregnant women, as well as what alternatives are available. Never consume OTC medicines without the clear permission from your doctor.

2. Know your Medications

Several common medications, such as Vicks Vaporub, whose active ingredients are perfectly safe might contain substances like caffeine, aspirin and alcohol, which are dangerous to foetal health. Always read the label before using them.




3. Don’t Cocktail your Drugs

Pregnancy is not the time you should be attempting treatments which fix multiple ailments. For example, medicines that fix the symptoms of cold, flu and allergies usually contain substances that are strictly off bounds for pregnant women. For example, acetaminophen works fine as an analgesic, but some variants of the drug come with decongestants like phenylephrine, which is harmful.

4. Skip OTC Medications Entirely

There are many ways to deal with our physical and mental issues that don’t involve pumping our bodies full of synthetic chemicals. You can attempt stress relieving exercises, massage, yoga, reflexology, meditation, and gentle cardiovascular exercise. Don’t forget to incorporate a balanced diet consisting of veggies, fruits, whole grains, nuts and seeds. Especially remember to stay hydrated with about 3-4 litres of water per day.


As someone concerned about the well-being of their baby, you certainly don’t want to add things to your body that might cause harm. Stopping the OTC medicines you’ve been using for years might not be entirely easy, but it is strictly recommended you avoid them for at least the first trimester of pregnancy, as this is when the baby’s organs develop. Over the next two trimesters, you can start incorporating a few of them back into your regimen, but always under your doctor’s guidance.
