Contraceptive pill issues?


Hello, I would like to ask about my current use of the "Aijia" oral contraceptive pill, which I have been taking consistently for almost a month.
Recently, I have been experiencing noticeable chest tightness and chest pain.
Is this considered a normal side effect of the medication? Should I stop taking it? Given these side effects, is it still appropriate for me to receive a vaccine?

Liu Xiaojie, 20~29 year old female. Ask Date: 2021/08/01

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, I am about to finish my birth control pills.
After finishing them, I will stop taking them for a while to see if the discomfort persists.
If it does not, it may be due to the birth control pills, and I can consider trying a different brand.
There is no relation between taking birth control pills and getting vaccinated.
Wishing you good health.

When it comes to understanding the side effects of emergency contraceptive pills (ECPs) and regular oral contraceptives like "Ai Ji" (which contains ethinylestradiol and drospirenone), it's essential to recognize that these medications can have various effects on the body, and individual responses may vary significantly.

Firstly, the symptoms you are experiencing, such as chest tightness and chest pain, are not typical side effects associated with oral contraceptives. Common side effects of hormonal contraceptives can include nausea, headaches, mood changes, breast tenderness, and changes in menstrual bleeding patterns. However, chest pain or tightness can be more concerning and may indicate a potential cardiovascular issue, especially if these symptoms are new or have worsened. It's crucial to differentiate between benign side effects and symptoms that could indicate a more serious condition.

The risk of serious side effects, such as thromboembolic events (blood clots), is a known concern with hormonal contraceptives, particularly in individuals with certain risk factors (e.g., smoking, obesity, a history of blood clots, or certain genetic predispositions). If you are experiencing chest pain, it is advisable to seek medical attention promptly to rule out any serious complications.

Regarding your question about whether you should stop taking the medication, this decision should be made in consultation with your healthcare provider. They can evaluate your symptoms in the context of your overall health and medical history. If the chest pain is determined to be related to the contraceptive, your doctor may suggest alternative methods of contraception or further investigation into the cause of your symptoms.

As for vaccination, generally, there is no contraindication for receiving vaccines while on hormonal contraceptives. Vaccines are safe and effective, and hormonal contraceptives do not interfere with vaccine efficacy. However, if you are feeling unwell or have concerning symptoms, it may be wise to discuss your situation with your healthcare provider before proceeding with vaccination.

In summary, while hormonal contraceptives can cause various side effects, chest pain is not a common or benign symptom and should be evaluated by a healthcare professional. It is essential to communicate openly with your doctor about any new or concerning symptoms you experience while on medication. They can provide personalized advice and ensure that you receive the appropriate care, whether that involves continuing your current medication, switching to another form of contraception, or addressing any underlying health issues.
