Preeclampsia is managed through blood pressure control, close monitoring, and ultimately delivery of the baby, which is the only cure. What you need to do depends on how far along you are, how severe the condition is, and whether you’re showing signs of dangerous complications. In mild cases diagnosed before 37 weeks, the goal is to buy time for the baby to develop while keeping you safe. In severe cases, delivery may need to happen right away.
Know the Warning Signs That Need Immediate Action
Preeclampsia can escalate quickly. Go to the emergency room if you experience a severe headache that won’t go away, blurred vision or seeing spots, severe pain in your upper belly (especially on the right side), or sudden shortness of breath. Mental confusion or altered behavior can signal that seizures are imminent. These symptoms mean the condition may be progressing to a life-threatening stage, and waiting even a few hours can be dangerous.
Not all preeclampsia announces itself with dramatic symptoms. Some people feel fine while their blood pressure and lab work tell a different story. That’s why regular prenatal appointments matter so much in the second half of pregnancy. Preeclampsia is typically caught when blood pressure readings hit at least 140/90, and it’s classified as severe when readings reach 160/110 or higher.
Medication to Lower Blood Pressure
If your blood pressure is elevated but not in the severe range, your provider will likely start you on an oral medication. The two most commonly used options during pregnancy are a calcium channel blocker and a beta-blocker, both of which have long safety records in pregnant patients. These bring your blood pressure down gradually to reduce the risk of stroke and organ damage while you continue the pregnancy.
When blood pressure spikes into the severe range, treatment happens in a hospital with IV medications that work faster. The goal is to bring numbers down within minutes, not days. You’ll also receive a medication delivered through an IV that helps prevent seizures, one of the most dangerous complications of severe preeclampsia. This drug works by relaxing blood vessels, protecting the barrier between your bloodstream and brain, and reducing swelling. It’s been the standard of care for decades and is highly effective.
When Delivery Is Recommended
Delivery is the only way to resolve preeclampsia. The timing depends on severity and gestational age.
- At or after 37 weeks: Delivery is recommended for anyone with preeclampsia, even if the condition appears mild. The baby is considered full-term, and there’s no benefit to continuing the pregnancy.
- 34 to 36 weeks with severe features: Delivery is also recommended. You’ll likely receive steroid injections to help the baby’s lungs mature quickly before birth.
- Before 34 weeks with severe features: Your medical team may try to manage the condition in the hospital for a short period to give the baby more time to develop, but only if you and the baby remain stable. This is called expectant management, and it requires constant monitoring.
The method of delivery, whether vaginal induction or cesarean, depends on how urgently the baby needs to come out and how your body responds to induction. Many people with preeclampsia deliver vaginally after being induced.
Monitoring at Home
If your preeclampsia is mild and your provider is managing it on an outpatient basis, home blood pressure monitoring becomes part of your daily routine. Use an automatic cuff-style monitor that wraps around your upper arm. Wrist and finger monitors give less reliable readings. Make sure the cuff fits your arm correctly, because an ill-fitting cuff produces inaccurate numbers.
When you take a reading, sit quietly for a few minutes first. Don’t measure right after exercise, caffeine, or smoking. Place the cuff on bare skin, not over clothing, and keep your arm supported at heart level. Take your monitor to your next appointment so your provider can verify it matches their office equipment. Write down every reading with the date and time so your care team can spot trends.
What Bed Rest Does and Doesn’t Do
Bed rest used to be a standard recommendation for preeclampsia, but there is no scientific evidence that it reduces preeclampsia risk or improves outcomes. Being completely inactive actually raises the risk of blood clots, which is already elevated during pregnancy. Your provider may ask you to reduce strenuous activity or take it easy, but strict bed rest is no longer considered helpful. If a provider recommends it, it’s reasonable to ask what specific benefit they expect and whether monitoring and medication might be more effective.
Prevention for High-Risk Pregnancies
If you’ve had preeclampsia before, have chronic high blood pressure, carry multiples, or have other risk factors, low-dose aspirin (81 mg daily) can reduce your chances of developing the condition again. ACOG recommends starting it between 12 and 28 weeks, ideally before 16 weeks, and continuing daily until delivery. This is a conversation to have early in pregnancy. Aspirin at this dose is safe for the baby and is one of the few interventions shown to meaningfully lower preeclampsia risk.
HELLP Syndrome: A Severe Complication
HELLP syndrome is a dangerous escalation of preeclampsia that affects the blood and liver. The name stands for the three problems it causes: breakdown of red blood cells, elevated liver enzymes, and low platelet counts. It develops in a small percentage of preeclampsia cases, usually in the third trimester or within the first week after delivery.
Symptoms often include pain in the upper right area of your abdomen (where your liver sits), nausea, vomiting, headache, and a general feeling of being unwell. Some people have no obvious symptoms at all and are diagnosed only through blood work showing abnormal liver function and dangerously low platelets. HELLP syndrome typically requires immediate delivery regardless of gestational age, because it can lead to liver rupture, stroke, or organ failure if left untreated.
Postpartum Preeclampsia
Preeclampsia doesn’t always end at delivery. Most cases of postpartum preeclampsia appear within 48 hours of giving birth, but it can develop up to six weeks later. This catches many people off guard, especially those who had normal blood pressure throughout pregnancy.
The warning signs are the same: severe headaches, visual disturbances, upper abdominal pain, and swelling that seems to worsen rather than improve after birth. If you experience any of these in the weeks after delivery, get your blood pressure checked immediately. Postpartum preeclampsia is treated with the same blood pressure medications and seizure-prevention protocols used during pregnancy, and it resolves once blood pressure stabilizes.
Having preeclampsia in any pregnancy also raises your long-term cardiovascular risk. Women who’ve had it are more likely to develop high blood pressure, heart disease, and stroke later in life. Annual blood pressure checks and heart-healthy habits after pregnancy aren’t optional extras. They’re part of the follow-through.
