Best Drinks for Headaches During Pregnancy

DetoxWater Editorial Team•Published November 5, 2026

Partly: when dehydration or a missed meal contributes to headaches during pregnancy, water or a nourishing drink may help by replacing fluid or providing energy, but it will not address every cause. Plain water is the best first choice; pasteurized milk, pasteurized juice or an oral rehydration solution may be useful in particular circumstances. There is no evidence here from pregnancy-specific studies comparing drinks for headache relief, so these are practical suggestions rather than proven treatments.

Which drinks are best for headaches during pregnancy?

For a mild headache without warning signs, try water first, particularly if you are thirsty or have not been drinking regularly. If you have missed a meal, have a meal or snack as well; a drink alone may not be enough.

Pasteurized milk can provide fluid and nourishment, while pasteurized juice may be an occasional option alongside food. An oral rehydration solution has a more specific use: replacing fluid and salts lost through vomiting or diarrhea. A caffeinated drink may be relevant if you regularly consume caffeine, but the amount matters during pregnancy.

The best drinks for headaches in general are not necessarily the right choice during pregnancy. Food safety, caffeine intake and the possibility of a serious pregnancy-related cause all need consideration.

Why might these drinks help, and when are they unsafe?

Headaches during pregnancy have many possible causes. Dehydration and missed meals are possibilities, but a new, severe or persistent headache can also signal a condition that needs medical assessment. The suggestions below do not establish what is causing a headache.

Plain water

Water is readily available, contains no caffeine and is a sensible way to replace fluid. If you have been drinking less than usual, drink some water and return to your normal fluid routine rather than forcing a large amount at once.

You do not need to add fruit, herbs or sugar for water to be useful. If a headache does not improve, keeps returning or comes with a warning sign, do not assume you simply need more water. Contact your maternity care team as described below.

Pasteurized milk or a fortified alternative

Pasteurized milk provides fluid and nutrients, including protein and calcium. It can be a convenient choice if you have not eaten and want something more nourishing than water, although a meal or snack may still be needed.

A fortified plant-based drink can also contribute fluid, but its protein, calcium and added sugar vary by product. Check the label and choose one that suits your dietary needs. Avoid unpasteurized milk during pregnancy because it can carry harmful germs.

Pasteurized juice

Pasteurized juice provides fluid and carbohydrate. A small serving with a meal or snack may be convenient if you have not eaten, but juice is not a proven treatment for headaches during pregnancy and is not necessary for hydration.

Choose pasteurized juice rather than an unpasteurized product. Juice can contain a substantial amount of sugar, so water is generally a better everyday thirst quencher. If you have diabetes, follow the eating and blood glucose plan agreed with your care team; if you suspect low blood sugar, follow your prescribed plan rather than relying on general headache advice.

Oral rehydration solution

An oral rehydration solution is designed to replace fluid and salts lost through vomiting or diarrhea. It may be useful when those losses make dehydration a concern, but it is not routinely needed for a mild headache when you can eat and drink normally.

Use a commercially prepared solution according to its package directions. If you are vomiting, have diarrhea or cannot keep fluids down, contact your maternity care team promptly rather than relying on a drink alone. Ask for individualized advice if you have kidney or heart disease, diabetes, or a prescribed fluid or salt restriction.

Coffee or tea, within the caffeine limit

If you regularly consume caffeine, a sudden change in intake can cause a withdrawal headache. A modest serving of your usual caffeinated drink may be an option, provided your total daily intake stays within the pregnancy limit below. You do not need to start drinking caffeine to manage headaches during pregnancy.

Caffeine content varies by drink and preparation, so check labels where possible and count all sources. If you want to reduce a regular caffeine habit, ask your maternity clinician how to do so. Do not assume a caffeine-free herbal tea is automatically safe in pregnancy; check its ingredients with your clinician.

How much is safe to drink during pregnancy?

The American College of Obstetricians and Gynecologists advises drinking 8 to 12 cups of water a day during pregnancy. That is approximately 1.9 to 2.8 liters, or 64 to 96 US fluid ounces. This is general guidance, not a target that overrides an individual medical plan.

Spread fluids throughout the day instead of forcing a large volume at once. Other beverages also provide fluid, and your care team can help you work out a suitable routine if nausea, activity, hot weather or a medical condition changes your needs. Drinking excessive water too quickly can be dangerous.

ACOG advises keeping caffeine intake below 200 milligrams per day during pregnancy. Include caffeine from coffee, tea, cola, chocolate and any medicines or supplements in that total. The amount in a cup of coffee or tea varies, so a cup count alone is not a reliable limit.

If you have kidney or heart disease, diabetes, or have been told to limit fluids, ask your clinician for an individual recommendation. Contact your maternity team promptly if vomiting or diarrhea is making it difficult to drink; do not try to make up for ongoing losses by forcing water alone.

When should you talk to your doctor about headaches during pregnancy?

Get emergency help for danger signs

Call emergency services for a sudden, extremely severe headache, or a headache accompanied by a seizure, fainting, confusion, weakness, trouble speaking, difficulty breathing, or fever with a stiff neck. Do not drive yourself or wait to see whether a drink helps.

Get urgent medical assessment for a severe or persistent headache, especially with vision changes, pain in the upper right abdomen, or new swelling of the face or hands. These can be signs of preeclampsia, a serious pregnancy-related condition. It can occur after the middle of pregnancy and after birth, even if earlier blood pressure readings were normal; do not wait for every symptom to appear.

Contact your maternity team about new or ongoing headaches

Tell your doctor or midwife about a new headache, one that keeps returning, or one that is different from your usual headaches. They can consider your symptoms and decide whether you need a blood pressure check or another assessment. Drinking water is not a substitute for that evaluation.

Contact your maternity team promptly if you cannot keep fluids down, feel faint, or have signs of dehydration such as very dark urine. Ask about safe headache management before taking an over-the-counter medicine or a combination product that contains caffeine. Do not stop a prescribed medicine without speaking to the clinician who prescribed it.

Frequently asked questions

Is sparkling water okay during pregnancy?

Plain sparkling water is generally an option if it agrees with you. Check flavored products for caffeine or other added ingredients.

Can I add lemon to water for a headache during pregnancy?

You can add washed lemon to water for flavor, but there is no evidence here that it relieves headaches better than plain water.

Is cold water better for headaches during pregnancy?

Cold or room-temperature water is fine if it agrees with you. There is no evidence here that either temperature is better for headache relief.
