Nausea can also occur with other forms of hormonal birth control, such as the patch, the ring or the birth control shot.
Most of the time, nausea from hormonal birth control passes on its own. There are also several steps you may be able to take to reduce any feelings of nausea you experience after you begin using the pill, patch or other hormonal contraceptive.
We’ve listed these steps below, along with more information on why and how the pill, patch, ring and other forms of hormonal contraception can make you feel nauseous.
Why Does Birth Control Cause Nausea?
First of all, it’s important to state that not all forms of birth control cause nausea. If you and your partner use condoms, a diaphragm, a cervical cap or another non-hormonal method such as the birth control sponge, there’s little to no risk of this type of birth control causing nausea.
Other non-hormonal methods of birth control, like withdrawal (the pull out method) or abstinence are also not linked to nausea.
Instead, nausea mostly occurs as a side effect of certain forms of hormonal birth control. These include the birth control pill, the patch, the vaginal ring, the Depo-Provera® shot and the hormonal IUD.
Nausea may occur with the birth control implant, but it’s worth noting that it’s typically a side effect experienced during or immediately following insertion and is not a long-term issue.
Nausea from birth control is typically caused by ethinyl estradiol — an estrogen hormone that’s found in the combination pill, patch and ring.
Estrogen can irritate the lining of your stomach, causing you to feel nauseous. When you start to use a form of birth control that contains estrogen, such as the combined pill, the increase in estrogen can trigger this stomach irritation and make you feel queasy.
Some progestin hormones used in the birth control pill, patch, ring and other forms of hormonal contraception may also contribute to nausea.
For the most part, research into hormonal contraceptives shows that the higher the dosage of estrogen and progestin hormones in the pill, the more likely it is to cause nausea.
For example, Enovid® — the first birth control pill, which was introduced in 1960 — contained, by today’s standards, an extremely large dose of estrogen and progestin hormones equivalent to roughly a 10-day dose of modern combination birth control pills.
As a result of this, systemic side effects such as nausea and vomiting were relatively common with early birth control pills.
In contrast, nausea isn’t as common with modern birth control pills, patches and other hormonal contraceptives, which use a lower dose of hormones than earlier medications.
For example, FDA clinical trial data for YAZ® (a common combined birth control pill that contains drospirenone and ethinyl estradiol) indicates that nausea or vomiting is only reported as a side effect by 4.2 percent of women.
Emergency contraceptive pills, which contain a relatively high dose of hormones, have a higher chance of causing nausea.
For example, about 12 percent of women who use ella®, an emergency contraceptive pill containing ulipristal acetate, report nausea as a side effect. Plan B One-Step®, another morning-after pill, causes nausea in about 14 percent of women according to FDA trial data.
How to Treat Nausea from Birth Control
Nausea from hormonal birth control is most common after initially starting the medication. Most of the time, any nausea you experience from the pill, patch, vaginal ring or other form of birth control will fade away gradually as your body gets used to the medication — typically within a few months.
If you’ve noticed yourself feeling nauseous after starting the birth control pill, patch, ring or any other form of hormonal contraception, there are several things that you can do that may reduce your symptoms:
Take your birth control pill with food. If you use the pill, try taking it with food instead of on an empty stomach. If you use it in the morning, do so after eating breakfast. If you use the pill at night, try taking it shortly after eating dinner or with a small snack.
Consider using an over-the-counter antacid. Antacids, which neutralize your stomach acid, can sometimes help to control nausea from the pill. If you feel nauseous after using the pill, try taking an over-the-counter antacid shortly before you take the pill.
Avoid oily, greasy or overly rich foods. Foods that are oily or very rich in flavor have a higher chance of leading to nausea than plain foods, meaning they’re best avoided if you often feel nauseous after taking the pill.
Consider taking the pill at night. Some women find that taking the pill at night makes nausea easier to deal with, as you’re more likely to be asleep when nausea symptoms are at their worst.
Avoid carbonated drinks. Carbonated drinks such as soda can make nausea worse by causing you to become bloated. Avoid fizzy drinks and instead stick to clear liquids such as water if you feel nauseous after taking your birth control pill.
Stick to plain, simple foods. Plain, starchy foods like potatoes, rice and bread tend to be easier for your stomach to tolerate than oily, rich or spicy foods, making them a good option if you feel nauseous.
Eat small portions of low-fat foods. If you feel nauseous after starting the birth control pill, try to avoid eating large portions. Stick to small portion sizes of foods that are low in fat, as these can help to ease nausea symptoms.
Don’t lie flat after eating. After you eat, avoid lying down flat for at least two hours, as this can worsen nausea.
It’s worth noting that most of the above suggestions are generalized for general nausea, but may prove helpful with nausea accompanying birth control.
As we mentioned above, nausea from hormonal birth control usually gets better over the course of several months.
However, if you have persistent or severe nausea after starting birth control that doesn’t appear to improve, it’s best to talk to your healthcare provider. Depending on your symptoms, they may recommend using a prescription anti-nausea medication or switching to another form of birth control.
If your healthcare provider thinks that your nausea is caused by the estrogen in the combined pill, they may recommend switching to the progestin-only mini-pill.
Vomiting and the Birth Control Pill
If you throw up after taking the birth control pill, you may need to take a second dose to make sure you’re protected from pregnancy.
Whether or not you need to take another pill depends on the total amount of time that’s passed between you taking the pill and vomiting:
If you took the pill more than two hours before vomiting, you’ve likely already absorbed the hormones in the pill and do not need to take a second dose.
If you took the pill less than two hours before vomiting, you’ll need to take another pill to make sure you’re protected.
If you’re currently taking the inactive pills (the pills included in your pack that don’t contain any hormones) and throw up after taking your birth control pill, you do not need to take an extra pill to stay protected.
If you have ongoing nausea that makes it difficult to take your birth control pill without vomiting, talk to your healthcare provider about changing to a form of birth control that’s more suitable for you.
In Conclusion
Nausea is one of the most common side effects of most birth control pills. It can also occur with other forms of hormonal contraception, such as the patch or vaginal ring.
Most of the time, nausea from birth control disappears over several months as your body gets used to the medication. If you’re prone to nausea after starting birth control, the tips above can help to ease your symptoms and make using your preferred form of birth control easier.
If you have persistent or severe nausea after starting hormonal birth control, the best thing to do is to talk to your healthcare provider. They may be able to prescribe a different form of birth control that’s less likely to make you feel nauseous.

Photographed by Jessica Nash. Just last spring, my pharmacy suddenly switched up my birth control brand. After taking the same exact pill every day for five years, I was a little shook — but my doctor said it was alright to go ahead and take the contraception, so I did. For the months that followed, I was nauseous pretty much every morning after I popped the new pill. I assumed it was because I wasn't drinking enough water or because I was taking it on an empty stomach (I take it right when I wake up), but when the feeling persisted I started thinking there might be another explanation. So I asked Angela Jones, MD, Astroglide's resident OB/GYN the question that I couldn't shake: Could something in this oral contraceptive be making me feel sick? "Birth control pills can cause any number of symptoms," she told me, then listed a few common ones: irregular bleeding or spotting, breast tenderness, acne, mood fluctuations... and nausea. I knew it! More than once I thought I was going to heave up last night's dinner during my morning commute. And I'm not alone. Nausea is the most common side effect of the pill. Below, some reasons why birth control pills can make you feel sick, and what you can do about it. Birth control pumps synthetic versions of the hormones estrogen and progestin into your body to prevent ovulation. Sometimes, the hormones themselves can cause discomfort and nausea. There's evidence, for instance, that estrogen can irritate the stomach lining. In fact, the higher the estrogen level in your pill, the more likely you might be to feel nauseous. Some birth control pills contain just synthetic progesterone (called progestin); other "combination pills" contain both progestin and estrogen. Different brands may have different levels of hormones or methods of delivery. That's why one brand of oral contraceptive may make you sick, while another may not. "Perhaps the current pill you're on isn’t the right one for you," Dr. Jones says, regarding my stomach-turning experience. "After all, one pill doesn't fit all." And she's right — every person's body has different needs and reactions, and it's important to listen to them. If you think you're on the wrong type of pill, have a talk with your doctor about your options. You may have one or more medical conditions that's could be a contraindication to being on the birth control pill (meaning: the combo of medical condition + oral contraceptive could cause harm). That includes a history of clotting disorders, hypertensive disorders, or migraine headaches with aura, says Dr. Jones. If you have any of these conditions, you definitely want to give your doctor a heads up — they might be the reason you're experiencing nausea-inducing side effects, and they can turn bad fast. First, give it three months, says Dr. Jones. That's how long it takes your body to adjust to a new pill. Most symptoms go away after just a few days, according to the Center for Young Women's Health. If they persist, you might want to consider either a progesterone-only (often called the mini pill), a non-pill form of contraceptive (including hormonal IUDs, diaphragms, vaginal rings), or a non-hormonal option (such as a copper IUD or condoms). Progesterone-only pills are less likely to cause nausea, Medical News Today says. But these kind of pills are less effective at preventing pregnancy than the combination pill because they must be taken at the exact same time every day to work. Also worth trying: At-home nausea remedies like eating ginger, staying hydrated, and trying out peppermint aromatherapy. With a little effort and the help of your doctor, you'll be able to find the perfect solution that keeps you protected and your stomach settled.Why do I feel nauseous?
