Experiencing dizziness and discomfort after taking the contraceptive pill for the first time?


Experiencing dizziness while taking birth control pills can feel like being on a boat, and the symptoms may persist for several hours, around five to six hours.
This dizziness is somewhat affecting my work, so I would like to know if this is normal.
I am currently using the brand "Yaz," and today marks exactly one week since I started taking it, but the dizziness continues.
I am concerned that aside from the side effects, women who are overweight may have a higher risk of blood clots when taking birth control pills.
Should I be worried that this dizziness could be caused by a blood clot? Should I stop taking the pills immediately and seek medical assistance again? How long should I wait before switching to a different medication?

Hello Aiko: The most common side effects of birth control pills are nausea, fatigue, and dizziness.
Your symptoms are likely just typical side effects of the contraceptive, so there’s no need to worry too much.
As for the risk of blood clots, it is indeed higher in individuals with obesity, but the overall incidence is very low, so you shouldn't be overly concerned.
I recommend that you go back and discuss your situation with your doctor to consider switching to a different type of birth control pill.

Experiencing dizziness after starting birth control pills can be concerning, and it's understandable that you're worried about the potential side effects and risks associated with hormonal contraceptives. Let's break down your situation and provide some clarity.

Firstly, dizziness is a known side effect of many hormonal contraceptives, including the one you mentioned, Yaz (悅姿). This is often due to the hormonal changes that occur in your body when you start taking these pills. The hormones in birth control pills can affect your blood pressure and circulation, which may lead to feelings of dizziness or lightheadedness. In many cases, these symptoms can subside after your body adjusts to the medication, which typically takes a few weeks. However, if the dizziness persists for more than a week, as you mentioned, it is advisable to consult your healthcare provider.

Regarding your concern about blood clots, it is true that certain birth control pills, particularly those containing estrogen, can increase the risk of venous thromboembolism (VTE), especially in women who are overweight, smoke, or have a history of blood clots. The risk of blood clots is generally higher in women who are over 35 years old and smoke, but it can also be influenced by other factors such as obesity. If you are experiencing persistent dizziness, it is essential to rule out any serious conditions, including the possibility of a blood clot.

If you are concerned that your dizziness could be related to a blood clot, it is crucial to seek medical attention promptly. Symptoms of a blood clot can include sudden dizziness, shortness of breath, chest pain, or swelling in one leg. If you experience any of these symptoms, you should go to the emergency room or contact your healthcare provider immediately.

As for stopping the medication, it is generally not recommended to discontinue birth control pills without consulting your doctor first. If you decide to stop taking the pills, your healthcare provider can guide you on how to do so safely and discuss alternative contraceptive options. If you switch to a different type of birth control, your doctor will provide specific instructions on when to start the new medication, which can vary depending on the type of contraceptive.

In summary, while dizziness can be a common side effect of birth control pills, persistent symptoms warrant a discussion with your healthcare provider. They can assess your individual risk factors for blood clots and determine the best course of action for your situation. It’s essential to prioritize your health and safety, so don’t hesitate to reach out for professional medical advice.
