Summary
- Acetaminophen is the preferred over-the-counter pain reliever during pregnancy, with a strong safety record for short-term use.
- Ibuprofen and aspirin (except for low-dose aspirin prescribed for specific conditions) should be avoided, especially after 20 weeks, due to risks to the fetus.
- Always consult your OB/GYN or healthcare provider before taking any medication during pregnancy, especially if you need pain relief for more than a few days or have other health conditions.
If you have questions about specific symptoms or need ongoing pain management, your healthcare provider can work with you on your personal course of care.
