Why Medicines During Pregnancy Need Medical Advice
However, certain medications have little or no impact on the baby during pregnancy. On the other hand, certain medicines may cross the placenta (the temporary organ that develops during pregnancy for the baby's nourishment).
These drugs reach the developing baby and may increase the risk of pregnancy complications such as birth defects or pregnancy loss.
Therefore, you should always consult your doctor before starting, stopping, or changing medicines during pregnancy.
How Can You Ensure That Medicine Is Safe To Take During Pregnancy?
You may require medicines for dental care, mental health management, or certain chronic health conditions, even during pregnancy.
Therefore, you should make sure that any doctor who is prescribing you a medicine knows that you’re pregnant.
Your pregnancy care provider or obstetrician will tell you if a prescription medicine is safe for you. They may advise you to stop taking medicine or switch to a safer option.
Most importantly, you should not stop taking prescription medicine without consulting your doctor.
Before using any over-the-counter medication, including those for pain, cold, vitamins, herbal preparations, or skin care, it is important to consult your doctor.
Verify their safety for you and your baby before use.
If you are taking any medicines, ask your doctor these questions at your first pregnancy visit:
- Can this medicine affect my baby’s development?
- Should I increase or reduce the dosage of my medicine?
- What medicines and herbal preparations should I avoid?
- Is it safe to continue this medication even during the breastfeeding period?
- Take it exactly as prescribed by your doctor
- Do not combine it with alcohol or other drugs.
- Do not take medicines based on someone else’s prescription.
How Certain Medicines Can Affect Your Pregnancy
The way a medicine can affect a pregnancy depends mainly on the medicine itself. The following are the possible effects:
| Type of Effect | Explanation |
| No effect | Some medicines may not affect pregnancy. |
| Direct impact | May harm the foetus or cause birth defects or death. |
| Indirect impact | May reduce blood flow to the placenta. |
| Effect on the placenta | May lower oxygen and nutrient supply, affecting growth. |
| Uterine contractions | May trigger contractions and lead to preterm birth. |
| Drug persistence | Some medicines stay in the body and may still cause harm. |
How Medicines During Pregnancy Can Affect Your Baby
Certain medications may harm your baby if taken without consulting your doctor. The following are the possible complications:
- Premature birth
- Low birthweight
- Birth defects
- Neonatal abstinence syndrome (also called NAS)
- Learning and behaviour problems later in life
- Miscarriage and stillbirth
- Sudden infant death syndrome (also called SIDS). This is the unexplained death of a baby younger than one year.
Which Medications Can Potentially Cause Birth Defects?
Always inform your doctor about all the medications you are taking. Some of them may harm your baby.
Your doctor might advise you to stop taking this medicine or adjust the dosage for you. These medicines include:
- Captopril
- Carbamazepine
- Codeine
- Enalapril
- Fluoxetine
- Hydrocodone

What Are The Medicines Your Doctor May Consider Safe to Take During Pregnancy?
There are cases where the risks to you or your baby from not taking a medicine are higher than the risks of taking it.
However, some medications carry less risk at certain stages of your pregnancy. Your doctor will guide you on which medications are safe to take and when.
Prenatal vitamins are safe during pregnancy. But it is still important to consult your doctor if you're pregnant.
If you want to take other vitamins, herbal remedies, and supplements, ask your doctor about their safety.
It is unclear if herbal medicines and supplements are safe to take while pregnant. So, better not to take them unless your doctor prescribes.
Importantly, you should not take any OTC medication during pregnancy unless it is necessary.
Can Medicines Taken Before Pregnancy Affect the Baby?
You may find it more challenging to conceive if you are taking certain medications.
In case you conceive, some medications may be harmful in pregnancy if you keep taking them without consulting your doctor.
Your doctor is the right person to decide that the benefits of taking medication to manage a health condition outweigh any possible risk to a pregnancy.
“It’s just a mild painkiller—what could go wrong?”
For many expecting mothers, this thought feels harmless. However, during pregnancy, even common over-the-counter medicines may carry unexpected risks for both you and your baby.
No medicine is completely risk-free in pregnancy. This is because drugs are not ethically tested on pregnant individuals.
Self-medication during pregnancy may seem simple. However, it can carry serious risks.
In fact, some medicines and home remedies are generally considered safe when used as directed.
Still, it is best to check with your doctor for confirmation—especially for anything not listed or if you are unsure about its safety. Self-medication during pregnancy may seem simple. However, it can carry serious risks.
In the end, protecting your baby starts with informed decisions. Even small precautions can make a big difference.
