If you are experiencing headaches during pregnancy, it is important to be cautious with medication. It is generally recommended to try non-pharmaceutical measures first, such as drinking enough water, getting enough sleep, avoiding stressful situations, and incorporating relaxation techniques. Acetaminophen (Tylenol) can be considered for headache relief, as it is usually safe during pregnancy. However, ibuprofen (Advil) is generally not recommended during pregnancy without medical supervision. If headaches are severe, persistent, or accompanied by other symptoms, it is advisable to consult a doctor.
