Birth control can raise blood pressure in some people, and the effect depends on which type you use
Hormonal birth control—particularly methods containing estrogen—can increase blood pressure in some users. The rise is usually modest, but for people who already have high blood pressure or are at risk for it, even a small increase matters. Not everyone who uses hormonal birth control will see a change in their blood pressure, and some methods carry less risk than others.
The mechanism is fairly well understood: estrogen affects how your body handles sodium and fluid, which can push blood pressure up. Progestin-only methods (like the minipill, implant, or hormonal IUD) carry much lower risk because they lack the estrogen component. If you take any form of hormonal birth control, your doctor should check your blood pressure before you start and periodically afterward.
Key Takeaways
- Combined oral contraceptives (pills containing both estrogen and progestin) pose the highest risk of blood pressure increase, though the rise is usually small.
- Progestin-only methods—including the minipill, implant, injection, and hormonal IUD—carry minimal risk of raising blood pressure.
- Your blood pressure should be checked before starting hormonal birth control and monitored regularly while you use it.
- If you develop high blood pressure while on hormonal birth control, switching to a progestin-only method or non-hormonal option often brings it back down.
Which birth control methods carry the highest risk
Combined oral contraceptives—the standard birth control pill containing both estrogen and progestin—carry the most documented risk. The effect tends to be dose-dependent: pills with higher estrogen doses raise blood pressure more than those with lower doses. Most modern pills contain 20 to 35 micrograms of ethinyl estradiol (the most common form of estrogen in pills), and at these doses, average blood pressure increases of 2 to 3 millimeters of mercury (mmHg) are typical in studies, though individual responses vary widely.
The patch and the vaginal ring also contain estrogen and carry similar risk to combined pills. The shot (medroxyprogesterone acetate, or Depo-Provera) contains only progestin and poses minimal risk. The minipill, implant, and hormonal IUD all use progestin alone and are considered safer choices for people concerned about blood pressure.
Non-hormonal methods—copper IUD, condoms, diaphragm, fertility awareness—do not affect blood pressure at all, since they contain no hormones.
How much your blood pressure might increase
Most people who experience a blood pressure rise from hormonal birth control see increases of 1 to 5 mmHg. For someone with normal blood pressure, this small change usually does not cross into the high blood pressure range. But for someone whose blood pressure is already elevated or borderline, even 3 mmHg can push them over the threshold into a diagnosis of hypertension.
A smaller subset of users—estimates range from 5 to 10 percent—experience larger increases of 10 mmHg or more. Researchers have not yet reliably identified which people will be in this group before they start the medication, which is why monitoring matters. Your blood pressure response to birth control is partly genetic and partly related to other factors like age, weight, and existing cardiovascular risk.
Who should be cautious about hormonal birth control
If you already have high blood pressure, most guidelines recommend avoiding combined oral contraceptives and other estrogen-containing methods. The American College of Obstetricians and Gynecologists (ACOG) lists uncontrolled hypertension as a reason to use progestin-only or non-hormonal methods instead. If your blood pressure is controlled with medication, the decision is more nuanced and depends on how well controlled it is and what other cardiovascular risk factors you have.
Age also matters: women over 35 who smoke and use combined birth control face a higher risk of blood clots and heart problems, independent of blood pressure effects. If you have a family history of early heart attack or stroke, or if you have migraine with aura, your doctor may steer you toward progestin-only or non-hormonal options.
Pregnancy itself raises blood pressure in some people, so the decision between birth control and pregnancy risk is not straightforward. A conversation with your doctor about your specific situation—your current blood pressure, your cardiovascular risk factors, and your contraceptive needs—is essential.
What happens if your blood pressure rises after starting birth control
If your blood pressure increases after you begin hormonal birth control, the first step is usually to switch methods rather than stop contraception entirely. Switching to a progestin-only method often brings blood pressure back down within a few months. Some people also see improvement by switching to a combined pill with a lower estrogen dose, though this is less reliable than switching to progestin-only.
If you need to stay on combined birth control for other reasons—such as managing heavy periods or endometriosis—your doctor may recommend starting blood pressure medication alongside it. This is a reasonable approach if the benefits of the birth control outweigh the cardiovascular risk, which your doctor can help you assess.
Monitoring your blood pressure while on birth control
Before you start any hormonal birth control, your blood pressure should be measured. This can happen at your primary care doctor's office, at a gynecology visit, or at a pharmacy with a blood pressure machine. If it is normal, you should have it checked again within three months of starting the method, then annually or according to your doctor's recommendation.
If you have a history of high blood pressure or other cardiovascular risk factors, more frequent monitoring—every three to six months—may be appropriate. Keep track of your readings if you check at home, and bring that record to your appointments. A sudden or sustained increase warrants a conversation with your doctor about whether to continue the current method.
Non-hormonal and progestin-only alternatives
If you need to avoid estrogen, several effective options exist. The copper IUD (Paragard) is over 99 percent effective at preventing pregnancy and lasts 10 years with no hormones at all. The progestin-only IUD (Mirena, Kyleena, Skyla, Liletta) releases a small amount of progestin directly into the uterus, minimizing systemic effects on blood pressure. The implant (Nexplanon) is a small rod placed under the skin of the arm and lasts three years. The minipill (norethindrone or desogestrel) is taken daily and contains only progestin.
Each method has different effectiveness rates, duration, and side effects unrelated to blood pressure. A conversation with your doctor about which fits your lifestyle and medical history is the best way to find the right fit.
Frequently Asked Questions
Does every type of birth control pill raise blood pressure?
No. Combined pills (containing estrogen and progestin) carry the most risk. Progestin-only pills, implants, IUDs, and shots do not meaningfully affect blood pressure. Non-hormonal methods like the copper IUD have no hormonal effect at all.
How long does it take to see a blood pressure change from birth control?
Changes can appear within the first few weeks, but the full effect usually develops over the first three to six months of use. This is why monitoring at three months is standard. If you switch away from a method that raised your blood pressure, it typically takes a few months for it to return to baseline.
If I have high blood pressure, can I ever use combined birth control?
If your blood pressure is well controlled with medication and you have no other major cardiovascular risk factors, some doctors may consider it on a case-by-case basis. Uncontrolled high blood pressure is a clear reason to avoid estrogen-containing methods. A detailed conversation with your doctor about your specific numbers and risk factors is necessary.
Will my blood pressure go back to normal if I stop taking hormonal birth control?
Usually, yes. Most people see their blood pressure return to baseline within a few months of stopping an estrogen-containing method. Some see improvement faster. If your blood pressure remains elevated after stopping, that suggests a separate issue worth discussing with your doctor.
Can I take blood pressure medication while on birth control?
Yes. If the benefits of a particular birth control method outweigh the blood pressure risk in your situation, taking blood pressure medication alongside it is a reasonable option. Your doctor can help you weigh whether this approach makes sense for you.
