According to Mayo Clinic, pregnant women can safely take an acetaminophen, such as Tylenol, to relieve a headache while pregnant as long as their doctor says it's okay. Massaging the neck and temples, lying down in a dark room with both eyes closed, placing a warm compress over the face or placing a cool compress over the neck and shoulders can also help relieve headaches during pregnancy.
According to MedlinePlus, hormonal changes can trigger headaches during pregnancy, and frequent headaches can also be a sign of preeclampsia, which is high blood pressure that develops in expecting women. Although it is not always possible to prevent headaches, there are some things women can do to minimize their chances of getting them.
The Mayo Clinic suggests practicing relaxation techniques, such as yoga and meditative breathing, as a preventative measure. Following a regular sleeping schedule, drinking plenty of fluids and frequently eating small meals throughout the day can also prevent headaches. Finding effective ways to manage stress can also minimize headaches, and this can be done by exercising regularly, delegating tasks to others and spending time with uplifting people. According to WebMD, chocolate, caffeine, artificial sweeteners and foods containing MSG (monosodium glutamate) can trigger headaches during pregnancy and should be avoided.
