Blood pressure medication side effects
I have blood pressure problem and doctors prescribed Vinicor D 20 mg . I've been taking it for 1-2 weeks but lately it's making my heart pound or beating in throbbing mode usually starting in the evening.( I take it in the morning at 11am )
I'm unable to sleep properly at night and the heart throbbing makes me wake up constantly at night.
Is the side effects normal or do I need to change medication?

Thanks for explaining it so clearly. I’ll answer the way I would in clinic.
A pounding or “throbbing” heartbeat after starting Vinicor-D is not something I’d ignore, especially since it’s waking you from sleep.
Vinicor-D commonly contains metoprolol + chlorthalidone (a beta blocker plus a diuretic). 
A few possibilities come to mind:
1. Low potassium / dehydration from chlorthalidone
* This is actually a common reason for palpitations / pounding heartbeat, often more noticeable in the evening or at night.
* You may also notice:
* weakness
* muscle cramps
* dry mouth
* extra thirst
* feeling “off” or anxious
2. Blood pressure dropping too much
* Can feel like pounding in the chest, dizziness, fatigue.
3. Heart rhythm irritation / ectopic beats
* Sometimes you feel every beat strongly even if the rate isn’t very fast.
4. An unrelated issue uncovered after starting treatment
* anemia, thyroid, anxiety/stress, caffeine, dehydration, etc.
My medical opinion:
Because:
* you’re 29
* symptoms started after beginning the medicine
* it’s persistent
* and it’s disturbing sleep
…I would contact the prescribing doctor within 24–48 hours and ask for review.
That review may include:
* BP readings (morning/evening)
* Pulse
* ECG
* Electrolytes (especially potassium/sodium)
* kidney function
Important:
Please don’t stop the medicine suddenly on your own tonight unless a doctor specifically told you to—beta blockers are usually better adjusted deliberately.
Seek urgent care tonight / immediately if:
* chest pain
* fainting / near fainting
* shortness of breath
* pulse racing continuously
* severe dizziness
* BP very low
* irregular heartbeat that won’t settle
A couple of quick questions so I can guide you better:
* What dose exactly is it—25 mg or 50 mg?
* What’s your BP and pulse lately?
* When the pounding happens: is the heart fast, irregular, or mainly strong/heavy beats?

In fact vincor is used to reduce fast heart rate.If you are getting heart throbbing in spite of taking it, a heart rhythm problem should be excluded.

It usually work good for most of the patients .
As a normal side effect it may be because of reflex tachycardia due to decrease in BP .
Or the symptoms you say are suggesting that it may be side effect of the medication u are taking ..
Metoprolol keeps a check on ur heart rate ..
But in some patients and overdose it can cause AV block and precipitate arrythmias which can lead to ur symtpoms
Secondly chlorthalidone can cause Hypokalemia which can also add to the symtpom.
But dont abruptly stop the medication .
Next Steps
Get a ECG
Serum electrolytes
Get back to me to consult on Practo
we will discuss in detail and take appropriate measures.

Hi,
This is a common side effect of Vinicor D in the initial weeks.
It improves with time, but the sleep disturbance needs attention.
Don't stop the medicine monitor BP and discuss with your doctor for possible dose adjustment or alternative.
Feel free to consult for further guidance. 👍
