While pregnancy brings joy and excitement for many people, it can also cause quite a few headaches. Headaches are common during pregnancy, especially early on. However, there are ways to manage the pain. Most often, headaches are not serious and do not cause harm. But it is important for you and your physician to monitor your headaches, as headaches can be associated with pre-eclampsia, a condition that can become serious and lead to complications. In this Q&A, Mount Sinai obstetricians Bruno Caridi, MD, and Jian Jenny Tang, MD, explain the different types of headaches you may experience, how to ease and prevent headaches, and how to know if you should be concerned.

How common are headaches during pregnancy?
Headaches are a very common medical condition, especially among those who are pregnant. There are three different types of headaches: tension headaches, cluster headaches, and migraine headaches. Almost 26 percent of pregnant patients will experience tension headaches, a mild-to-moderate pain that is often described as having a tight band around the head. Pain may also be located toward the neck with tension headaches. Cluster headaches are characterized by intense pain, often concentrated around one eye or on one side of the head, and occurring frequently. Cluster headaches are very uncommon in women, occurring less than one percent of the time. A migraine headache is usually unilateral, which means it is concentrated on one side of the head. During pregnancy, about 10 percent of people will have experienced some type of migraine headache. With migraine headaches, an individual may be more sensitive to light, to certain types of noise, and to certain smells. Migraine headaches can also be accompanied by other symptoms, such as nausea. After 20 weeks of pregnancy, careful attention needs to be paid to headaches to ensure they are not a symptom of pre-eclampsia. Headaches associated with pre-eclampsia are usually global tension headaches, occurring all around the head.
What is pre-eclampsia?
While the causes of pre-eclampsia are not understood, the condition may be related to placenta and maternal vascular dysfunction. However, high blood pressure and protein in the urine are the most common signs. In rare cases, the condition causes seizures. If you are experiencing frequent headaches, it is important to have your vitals checked by your physician to see if your blood pressure is elevated. Also, be aware of any headache that is different from what you’ve previously experienced. Changes in vision, such as spots or blurriness, or right upper quadrant abdominal pain or epigastric pain are all signs of pre-eclampsia.

What are the best over-the-counter and non-pharmacological treatments for alleviating pregnancy-related headaches?
The first line of treatment recommended is Tylenol®. Patients may take three regular strength Tylenol (975 milligrams total), or two extra strength Tylenol (1000 milligrams total). Tylenol can be taken every six to eight hours, and must not exceed 3000 milligrams per day. This medication is an excellent initial line of over-the-counter treatment for headaches. We do not recommend migraine medicines that you may have been taking pre-pregnancy, such as sumatriptan. Besides Tylenol, caffeine is a great way to help alleviate headaches. Caffeine is fine to use in moderation, and should not exceed 200 milligrams per day. If the headache persists, then the patient should contact their physician. Other non-pharmacological treatments include drinking plenty of fluids to stay well hydrated, keeping your blood glucose levels up by snacking or eating light meals every few hours throughout the day, getting adequate rest, moving to a dark room to avoid light, or placing a damp washcloth over your forehead and relaxing. Other stress reduction or relaxation techniques, such as taking a shower to relax your muscles, listening to soothing music, and aromatherapy can help. Deep mindful breathing and light exercise, such as yoga, are other common non-pharmacological methods that help with headaches. Prevention is key.
How can I prevent pregnancy-related headaches?
Experiencing headaches during pregnancy does not mean you have pre-eclampsia. Other common causes can include dehydration, low blood glucose levels, lack of sleep, and anemia. As such, staying well hydrated and getting enough food and sleep are good ways to prevent headaches. Also, if you consume a lot of caffeinated beverages before pregnancy, abruptly scaling back on caffeine could trigger headaches related to withdrawal. If you plan to give up caffeine, easing yourself off of these beverages gradually can prevent headaches. Your pregnant body is going through a lot of changes, especially during the first trimester. Knowing how to adapt to these rapid changes will help put both your body and mind at ease, so you can focus on your baby.
