First Time Taking Birth Control Pills: Dealing with Nausea and Concerns - Obstetrics and Gynecology

First time taking birth control pills (Yueji)?


On the evening of November 22nd at 10:30 PM, I took my first birth control pill (on the fifth day of my menstrual cycle).
The next day (23rd), I woke up with severe nausea, which improved somewhat after an hour.
Is this discomfort due to just starting the medication, or is my body not suited for this brand of medication? Should I finish this pack? I previously took two doses of the Plan B pill and stopped after two days without any discomfort.
Thank you, doctor.

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, try taking a few more pills to see if you still experience any discomfort.
If you do, stop the medication and wait until your period arrives to take the medication that does not cause you any discomfort.
Wishing you good health.

More Info


Taking birth control pills for the first time can be a significant adjustment for many women, and experiencing nausea is a common side effect during the initial phase of usage. When starting a new contraceptive regimen, especially hormonal birth control, your body may take some time to adapt to the changes in hormone levels.
Nausea is one of the most frequently reported side effects when beginning birth control pills, particularly those that contain estrogen and progestin. This is because these hormones can affect the gastrointestinal system and may lead to feelings of nausea, especially during the first few weeks of use. In your case, since you started taking the pill on the fifth day of your menstrual cycle, your body is likely adjusting to the new hormones.
It’s important to note that while nausea can be a normal side effect, it should not be severe or debilitating. If the nausea persists or worsens, it may indicate that your body is not responding well to this particular formulation of the pill. In such cases, it is advisable to consult with your healthcare provider. They may recommend trying a different brand or formulation that might be better suited to your body’s needs.
Regarding your previous experience with the contraceptive pill "Chiliane," it’s not uncommon for women to have different reactions to different brands or types of birth control pills. Each formulation contains varying levels of hormones, and individual responses can vary widely. Some women may tolerate one brand well while experiencing side effects with another.
As for whether you should finish the pack you are currently taking, it is generally recommended to complete the pack unless you experience severe side effects. This is because stopping the pill abruptly can lead to hormonal fluctuations and may increase the risk of unintended pregnancy. However, if the nausea is intolerable or if you have any other concerning symptoms, it’s best to reach out to your healthcare provider for personalized advice.

In addition to nausea, other common side effects of starting birth control pills can include breast tenderness, mood changes, and slight weight gain. Most of these side effects tend to diminish after the first few months as your body adjusts. However, if you experience any severe side effects such as headaches, vision changes, or leg swelling, you should seek medical attention immediately, as these could indicate more serious complications.

In summary, while nausea can be a common side effect when starting birth control pills, it’s essential to monitor your symptoms and communicate with your healthcare provider if they persist or worsen. They can provide guidance on whether to continue with the current pill or consider alternatives that may be more suitable for you. Remember, your comfort and health are paramount, and there are many options available to help you find the right birth control method for your needs.
