Not all over-the-counter (OTC) medicines are always safe during pregnancy. In fact, some of these medications can harm the developing fetus. It is essential to consult your healthcare provider before taking any medication, including OTC drugs, herbal supplements, or vitamins, to assess the potential risks and benefits for you and your fetus [\[1\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S1>).

## Why should you consult a doctor before taking OTC medicines?

Although OTC medications are easily available, this does not mean they are free of risks during pregnancy. Some of these medicines may contain ingredients that could negatively affect fetal development at different stages of pregnancy [\[2\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S2>). For example, some common pain relief or allergy medications may not be suitable for use during pregnancy [\[1\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S1>). Furthermore, a pregnant woman's body undergoes physiological changes, such as increased heart and kidney function, which can affect how the body processes medications [\[2\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S2>).

## What are the potential risks?

Some medications may increase the risk of health problems for the fetus, such as certain birth defects, premature birth, or even pregnancy loss [\[3\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S3>). It is important to note that information about the safety of many drugs during pregnancy is limited, as pregnant women are often not included in initial clinical studies for new drugs [\[3\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S3>). This makes it difficult to accurately determine the safety of some medications without specialized medical consultation.

## Practical tips for choosing medications during pregnancy

- **Talk to your healthcare provider:** Before trying to conceive or as soon as you know you are pregnant, talk to your doctor about all the medications you are currently taking, including prescription drugs, OTC medicines, herbal supplements, and vitamins [\[2\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S2>).

- **Read labels carefully:** Check medicine labels and any other information provided with the medication to learn about potential risks during pregnancy [\[2\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S2>).

- **Avoid speculation:** Do not trust information you find online, in chat rooms, or on social media without verifying it with your doctor. Some products claiming to be "natural" may not be safe [\[2\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S2>).

- **Prenatal vitamins:** Talk to your doctor about taking prenatal vitamins, which contain the appropriate amounts of vitamins and minerals necessary for pregnancy, such as folic acid, which helps prevent birth defects of the brain or spine [\[2\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S2>).

## What if I took medication before I knew I was pregnant?

If you are concerned about medications you took before you discovered you were pregnant, speak with your healthcare provider about your concerns. Some drugs may be harmful when taken during pregnancy, but others are unlikely to cause harm [\[3\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S3>). It is important not to stop taking any prescribed medication without consulting your doctor first, as not using a necessary medication may be more harmful to you and your fetus than using it [\[1\]](<https://clinicsjo.com/en/faq/are-over-the-counter-otc-medicines-always-safe-during-pregnancy#source-S1>).
