[|Human|] I am 73 woman diagnosed with high bp; doctor prescribed lisinophil (water) 12.5 and 50 mg er metopholol. Have taken for about 2 months; about 3 weeks ago started having palpitaions during the night with irregular heart beats; some nites kept me awake; the palpitations happening sometimes during daytimes. Last few nights the palpitations and irregular heartbeats have come not as bad but I want to get off this metropolol for tiredness and low bp readings 90/60 110/70 106/66, etc. Have to take this pill for two more nights before I can see the doctor and am feeling very scared for the palpitations and irregular beats at night about 20-30 min after I take the pill... help.
[|AI|]  Hello, This can be a cardiac arrhythmia like atrial fibrillation, in which heart rate suddenly goes up and also suddenly decreases. Blood pressure falls during these episodes and one can have dizziness, fainting, blackouts, sometimes syncope. Usually ECG is normal as it is usually done in between the episodes. ECG done during episodes will show abnormality. You will need 24 hour holder monitoring. So visit nearby cardiologist for this investigation.  Also, hemoglobin and thyroid test should be done.  Is there any stress or anxiety associated, as it can lead to palpitations.  Also, Rather than stopping, metoprolol dose can be decreased to 25 mg or better option, you can ask to decrease the dose of lisinopril. Stopping metoprolol can cause increase in palpitations. The decision will be taken after seeing the ECG, as what the cause of palpitations and all. If BP goes down, you can have salt and sugar water whenever needed basis.
