Tachycardia


Hello Dr.
He: I have a problem with tachycardia and am currently taking Concor 1.25 mg, one tablet in the morning and one in the evening.

1.
Can this medication help lower my heart rate and relieve chest tightness?
2.
After starting the medication, I felt dizzy every day for two weeks, so I measured my blood pressure for a week.
My systolic pressure was around 100 and diastolic pressure around 60.
Should I ask the doctor during my follow-up visit if I need to reduce the dosage?
3.
However, during cold weather, my blood pressure is quite stable, around 110 systolic and 70 diastolic.
Is it possible that my blood pressure is lower in the summer?
4.
I have been taking antihistamines for allergic rhinitis for several years.
Recently, I have experienced headaches and dizziness, and my neurologist prescribed Betahistine 5 mg, Micronized Dihydroergotamine 500 mcg, Bupropion 500 mg, Mirtazapine 6 mg, and Xanax 0.25 mg.
Is there any interaction between these medications?
5.
Since I have allergic rhinitis, can I ask my cardiologist to prescribe medication for it during my follow-up visit? Currently, I am getting my rhinitis medication from a clinic, and I have to visit different hospitals and clinics.
Can I request allergy medication from my cardiologist to avoid going to multiple locations? The neurologist's medications are only for my recent daily headaches and dizziness, and I will stop taking them once the symptoms improve.
The long-term medications I take are just the antihistamine for allergies and Concor.
Will taking these together have any adverse effects? I appreciate your guidance, Dr.
He.
Thank you very much.

Hello, during the summer, blood pressure tends to be lower.
If you are taking medication and your blood pressure drops too low, you might consider discussing a dosage reduction with your physician.
Is there any conflict with taking these medications together? It should be fine.
Additionally, can you ask your doctor to prescribe antihistamines for allergies? This should also be discussed with your physician.
Take care from Changhua Hospital.

Managing rapid heartbeat and understanding the effects of medications can be quite complex, especially when multiple health conditions and medications are involved. Let's break down your concerns regarding the medication you are taking, its effects, and any potential interactions with other medications.

1. Effectiveness of KanKen (康肯): KanKen, which is likely a reference to a medication used for managing heart rate, can indeed help in reducing heart rate and alleviating symptoms like chest tightness. Medications that are typically prescribed for rapid heartbeat often include beta-blockers or calcium channel blockers, which work by slowing down the heart rate and reducing the workload on the heart. If you are experiencing persistent symptoms despite taking the medication, it is crucial to discuss this with your healthcare provider.

2. Monitoring Blood Pressure: You mentioned experiencing dizziness and low blood pressure readings (systolic around 100 and diastolic around 60). It is essential to monitor your blood pressure regularly, especially after starting a new medication. If you notice consistent low readings and symptoms like dizziness, it would be wise to consult your doctor about possibly adjusting your dosage. Your doctor may recommend a dose reduction or switching to a different medication based on your symptoms and blood pressure readings.

3. Seasonal Blood Pressure Variations: It is not uncommon for blood pressure to fluctuate with the seasons. Cold weather can cause blood vessels to constrict, which may lead to higher blood pressure readings, while warmer weather can have the opposite effect. If you find that your blood pressure is stable in colder weather but drops in the summer, this could be a normal physiological response. However, it is essential to keep your healthcare provider informed about these changes.

4. Medication Interactions: You are currently taking several medications, including antihistamines for allergic rhinitis and medications prescribed by a neurologist for headaches and dizziness. While many medications can be taken together, there is always a risk of interactions. For instance, some antihistamines can cause sedation, which may be exacerbated by other medications that have similar side effects. It is crucial to inform all your healthcare providers about every medication you are taking to avoid potential interactions. If you experience new symptoms after starting a new medication, it is essential to report these to your doctor.

5. Consulting Your Cardiologist for Allergic Rhinitis: It is entirely reasonable to ask your cardiologist to prescribe medications for your allergic rhinitis during your visit. Many doctors are comfortable managing multiple conditions, and it can be more convenient for you to have all your prescriptions from one provider. Just ensure that your cardiologist is aware of all the medications you are currently taking, including those for your allergies, to avoid any potential interactions.

In summary, managing rapid heartbeat and associated symptoms requires careful monitoring and communication with your healthcare providers. It is essential to report any new or worsening symptoms, discuss any concerns about medication interactions, and ensure that all your healthcare providers are aware of your complete medication list. This collaborative approach will help ensure that you receive safe and effective care tailored to your needs. Always prioritize your health and do not hesitate to seek clarification or assistance from your healthcare team.
