Can a pregnant woman at 7 weeks take headache medication? Will it cause a miscarriage or affect the baby? (My wife, unable to bear the headache, took a well-known Japanese brand pain reliever, which contains 200mg of ibuprofen.)
Answer: Ibuprofen is classified as a pregnancy category B medication; however, its use in the third trimester or close to delivery is classified as category D.
At 7 weeks of pregnancy, it is unlikely to cause a miscarriage or have an adverse effect on the baby.

More Info


When it comes to taking pain relievers during pregnancy, particularly at 7 weeks gestation, it is crucial to understand the potential risks and benefits associated with the use of medications like ibuprofen. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to relieve pain, reduce inflammation, and lower fever. However, its safety profile during pregnancy varies depending on the stage of pregnancy.

In the first trimester, which includes the 7th week of pregnancy, ibuprofen is generally classified as a Category B medication by the FDA. This means that animal reproduction studies have not demonstrated a risk to the fetus, and there are no adequate and well-controlled studies in pregnant women. However, it is essential to note that while the risk of miscarriage or congenital malformations associated with ibuprofen use in early pregnancy is considered low, it is not entirely without risk.

The primary concern with taking ibuprofen during pregnancy, especially in the later stages (third trimester), is its potential to cause complications such as premature closure of the ductus arteriosus, a vital blood vessel in the fetus, and other issues related to fetal kidney function. Therefore, while taking ibuprofen at 7 weeks may not pose a significant risk, it is always advisable to use the lowest effective dose for the shortest duration necessary.

In the case of the specific medication mentioned, EVE, which contains 200 mg of ibuprofen, it is essential to consider the individual circumstances of the pregnant woman. If she is experiencing severe headaches that are not manageable through non-pharmacological methods (like rest, hydration, or cold compresses), it may be reasonable to use ibuprofen for short-term relief. However, it is crucial to consult with a healthcare provider before taking any medication during pregnancy to ensure it is safe and appropriate for her specific situation.

Additionally, pregnant women should be aware of alternative pain relief options that may be safer during pregnancy. Acetaminophen (Tylenol) is often recommended as a first-line treatment for pain relief during pregnancy, as it is generally considered safe when used as directed. However, even with acetaminophen, it is important to avoid excessive use and to consult with a healthcare provider regarding the appropriate dosage.

In summary, while taking ibuprofen at 7 weeks of pregnancy may not significantly increase the risk of miscarriage or harm to the fetus, it is essential to approach medication use with caution. Pregnant women should always consult their healthcare provider before taking any medications, including over-the-counter pain relievers, to ensure the safety of both themselves and their developing baby. If headaches persist or worsen, it is advisable to seek medical attention to explore other underlying causes and appropriate treatment options.
