Antihypertensive medications


Thank you, doctor.
Good afternoon! 😃 Since I had high blood pressure during late pregnancy and postpartum (I didn't have it before pregnancy), I found out I have heart failure during my check-up.
I'm taking antihypertensive medication to control my blood pressure (it was around 140-150 right after giving birth).
I'm currently taking one tablet of Caduet daily, and my blood pressure was generally controlled within 120/80, but yesterday it rose to around 125/82 (isn't the standard 120/80?).
I'm wondering why my blood pressure is still high despite taking medication.
I started to get increasingly anxious, and at one point, it measured 144.
Could it be that my medication is no longer effective? I'm really worried that my heart condition might be worsening...
I have so many questions, but I truly appreciate your patience in answering them.
It really helps reassure patients a lot.
Thank you infinitely!

Hello, we are human beings, not robots.
It's normal for blood pressure to fluctuate due to internal and external environmental changes.
Even the best students don't score 100 on every test; having one poor performance doesn't make them a bad student.
Similarly, we are treating high blood pressure, not just focusing on the numbers.
Fluctuations are normal, especially during late pregnancy and postpartum, which may also be temporary changes.
Long-term medication may not always be necessary.
It's important to allow yourself some grace and live in the moment; focusing on making each moment count is more important.
Who knows what tomorrow will bring? Enjoy life and spend quality time with your children.
Wishing you peace and good health.
Changhua Hospital cares about you.

Managing hypertension during pregnancy is a critical concern for both maternal and fetal health. It is essential to understand the implications of high blood pressure and the medications used to manage it, especially in the context of pregnancy.
Firstly, it is important to recognize that hypertension can develop during pregnancy, even in women who did not have high blood pressure prior to conception. This condition, known as gestational hypertension, can lead to complications such as preeclampsia, which poses risks to both the mother and the baby. The causes of elevated blood pressure during pregnancy can include placental abnormalities, maternal immune responses, hormonal imbalances, and pre-existing health conditions.

In your case, it appears that you have been diagnosed with heart failure and are currently managing your blood pressure with medication. You mentioned that your blood pressure readings have been fluctuating, and despite taking medication, you are experiencing some anxiety about the effectiveness of your treatment. It is essential to understand that blood pressure can vary throughout the day due to various factors, including stress, activity levels, and even the position in which you measure your blood pressure.
The target blood pressure during pregnancy is generally considered to be around 120/80 mmHg, but slight variations above this threshold, such as 125/82 mmHg, may not necessarily indicate a failure of your medication. However, consistently elevated readings, especially those reaching 140 mmHg or higher, warrant further evaluation. It is crucial to monitor your blood pressure regularly and report any significant changes to your healthcare provider.

Regarding the medications you are taking, it is vital to discuss with your healthcare provider whether they are appropriate for your condition during pregnancy. Some antihypertensive medications are safer than others when it comes to fetal exposure. For instance, medications such as methyldopa, labetalol, and certain calcium channel blockers are often preferred during pregnancy due to their safety profiles. On the other hand, some medications may pose risks to fetal development and should be avoided.

If you are experiencing increased anxiety about your blood pressure and heart condition, it is essential to communicate this with your healthcare provider. They may consider adjusting your medication regimen or implementing additional strategies to manage your blood pressure and anxiety. Lifestyle modifications, such as a balanced diet low in sodium, regular physical activity (as permitted), and stress-reduction techniques, can also play a significant role in managing hypertension.

In conclusion, managing hypertension during pregnancy requires a comprehensive approach that includes regular monitoring, appropriate medication management, and lifestyle modifications. It is crucial to maintain open communication with your healthcare provider to ensure that both your health and the health of your baby are prioritized. If you have concerns about the effectiveness of your medication or your blood pressure readings, do not hesitate to seek further evaluation and guidance from your healthcare team. Your health and peace of mind are paramount during this critical time.
