Is it normal to throw up during birth control? Understanding the causes and what to do

5 min read

According to one source, nausea is one of the most commonly reported side effects when starting hormonal contraceptives. While it may not always involve vomiting, an upset stomach can definitely happen. If you've wondered, is it normal to throw up during birth control, the answer is that it can be, especially during the initial adjustment period, but understanding the cause and proper steps is key.

Quick Summary

Vomiting during hormonal birth control is often a temporary side effect of adjusting to new hormone levels. It can reduce the pill's effectiveness if it occurs shortly after a dose. Simple strategies can help manage the discomfort, but persistent symptoms may indicate a need to consult a healthcare provider about alternative options.

Key Points

  • Common and Temporary Side Effect: Nausea or vomiting is a normal side effect, especially during the first few months, as the body adjusts to hormonal changes.

  • Estrogen is the Culprit: The estrogen in combination pills can irritate the stomach lining and increase acid, causing queasiness.

  • Timing is Key: Taking your birth control pill with food or at bedtime can often prevent or minimize nausea.

  • Vomiting Reduces Effectiveness: If you vomit within 2-3 hours of taking a combined pill, its effectiveness may be compromised, and you should take another dose.

  • Consider Alternatives for Persistent Symptoms: If nausea or vomiting lasts longer than 3 months, talk to your doctor about switching to a lower-estrogen pill or a non-oral method like an IUD or implant.

  • When in Doubt, Use Backup: If you've been sick for more than 24 hours, use backup contraception (like condoms) for at least 7 days to ensure protection.

  • Rule Out Other Illnesses: Be sure to rule out other causes for vomiting, such as a stomach virus or pregnancy.

Understanding the causes of nausea and vomiting on birth control

For many, the initial adjustment period to hormonal contraception can be accompanied by uncomfortable symptoms like nausea, which can occasionally lead to vomiting. The primary reason behind this is the change in hormone levels, particularly the increase in synthetic estrogen. Estrogen can irritate the stomach lining and increase stomach acid production, leading to a feeling of queasiness.

Hormonal fluctuations

When you start a new birth control regimen, your body needs time to acclimate to the synthetic hormones, estrogen and progestin. This adjustment period can trigger a variety of side effects, with nausea being one of the most common. As your body's natural hormone production is suppressed and replaced by the hormones in the pill, this creates a temporary shift that can affect your digestive system. This effect is often more pronounced with combination pills that contain both estrogen and progestin, especially those with higher doses of estrogen.

Timing of the pill

The timing of when you take your birth control can also play a significant role. Many women report that taking their pill on an empty stomach can trigger nausea. Taking it with food or at bedtime can often help to mitigate this effect. Additionally, emergency contraceptive pills, which contain a much higher dose of hormones, are more likely to cause significant nausea and vomiting.

What to do if you throw up after taking your pill

If vomiting occurs after taking a birth control pill, the time elapsed since ingestion is critical in determining the next steps to maintain contraceptive effectiveness.

  • Within 2-3 hours: If you throw up within 2-3 hours of taking an active pill, your body may not have had enough time to absorb the hormones. In this case, you should take another active pill from your pack as soon as you can keep it down. For progestin-only pills, the window is even shorter, and you must take a replacement pill within 3 hours of your usual time. Backup contraception, such as condoms, should be used for the next two days.

  • More than 3 hours: If more than 3 hours have passed since you took your pill, it's likely that your body has absorbed the necessary hormones, and you should be protected. Continue taking your pills as scheduled and monitor for any ongoing issues.

  • Repeated vomiting: If you experience persistent or repeated vomiting and diarrhea for more than 24 hours, the effectiveness of your pill can be reduced. You should continue taking your pills as scheduled but use a backup contraceptive method for at least 7 days after the illness subsides.

Managing and preventing birth control-related nausea

For many, mild nausea is a temporary side effect that can be managed with simple adjustments.

Lifestyle adjustments

  1. Take with food: Avoid taking your pill on an empty stomach. Taking it with your largest meal of the day or with a snack can help.
  2. Adjust the timing: Try taking your pill at bedtime. Since you'll be asleep, you are less likely to notice any potential nausea.
  3. Eat bland foods: When feeling queasy, stick to plain foods like crackers, toast, and rice.
  4. Stay hydrated: Sip on clear, cold liquids throughout the day to prevent dehydration, which can worsen nausea.
  5. Use ginger or peppermint: Ginger tea, ginger ale, or peppermint can help calm your stomach.

Medication and other options

If lifestyle changes are not enough, or if the nausea is severe, other options may be necessary:

  • Over-the-counter (OTC) medication: Some people find relief with OTC anti-nausea medications or antacids, but you should always consult a doctor or pharmacist to ensure they won't interfere with your birth control.
  • Lower-estrogen pill: Your doctor may recommend switching to a pill with a lower dose of estrogen, as this is often the culprit for nausea.
  • Progestin-only pill (minipill): For some, a progestin-only pill may be a better option, as they tend to cause less gastrointestinal upset.
  • Alternative birth control methods: If oral contraceptives continue to cause problems, your doctor might suggest a non-oral method, such as a vaginal ring, patch, implant, or IUD, which bypasses the digestive system and avoids related side effects.

When to contact a healthcare provider

While mild, temporary nausea is common, it's important to know when to seek medical advice. If any of the following apply, you should schedule a consultation with your doctor:

  • Nausea and vomiting persist for more than three months, interfering with your daily routine or quality of life.
  • Vomiting is severe and prevents you from keeping pills down regularly.
  • You suspect your nausea is a sign of pregnancy, especially if you have missed pills or had unprotected sex.
  • You experience other concerning symptoms, such as severe headaches, chest pain, or vision changes, which could be signs of a serious, though rare, side effect like a blood clot.

Comparison of oral birth control options for nausea

Feature Combined Oral Contraceptives (COCs) Progestin-Only Pill (Minipill) Alternative Methods (IUD, Implant)
Hormones Estrogen and Progestin Progestin only Progestin (Hormonal IUD/Implant) or Copper (Non-hormonal IUD)
Nausea Risk Higher, especially with higher estrogen doses Lower risk of nausea due to absence of estrogen Very low to no risk, as hormones bypass the digestive system
Hormone Levels Fluctuating, depending on pill phase Consistent, low dose of progestin Steady, local hormone release (for hormonal methods)
Absorption Through the stomach, affected by vomiting within 2-3 hours Through the stomach, affected by vomiting within 3 hours Bypasses the stomach entirely
Best For Those who tolerate estrogen well and prefer a combined hormone approach Those sensitive to estrogen or prone to nausea Long-term contraception without daily pills or hormone-related nausea

Conclusion

Experiencing nausea or even vomiting during birth control is a relatively common and usually temporary side effect, particularly when first starting oral contraceptives. It is most often caused by your body adjusting to the hormonal changes, with estrogen being the main contributor. Taking simple steps like adjusting the timing of your pill, eating with it, and trying home remedies can often provide relief. However, it is crucial to know how to respond to vomiting to maintain the pill's effectiveness, especially if it occurs shortly after a dose. If severe or persistent symptoms occur, discussing other options with a healthcare provider is the safest and most effective way to find a suitable contraceptive method that works for your body. A wide range of options exist to ensure effective contraception without compromising your comfort.
