Is it possible to combine Betaloc and Ivohart at the same time as Escitil?

Interactions occur at every level.

Taking Betaloc in combination with Ivohart may cause your heart rate to slow down too much. If medications have been prescribed by different doctors, a consultation is necessary to determine whether the benefits of taking them outweigh the risk of interactions.

If you experience dizziness, pain in the heart area, slow or irregular heart rhythm, shortness of breath, fainting, or other worrying symptoms, contact your doctor immediately.

Dangerous cardiac arrhythmias are also caused by combining Escitil with Ivohart.

What's more, the drugs you have been using so far, i.e. Escitil and Betaloc ZOK, are also not indifferent to each other.
If you take both medicines at the same time, the effects of metoprolol in Betaloc may increase the effect of your blood pressure and slow down your heart rate. In addition, you may experience symptoms that indicate bronchospasm (shortness of breath, wheezing, cough), especially if you have asthma.

I recommend consulting a doctor. They may consider changing the medication or dosage.
