Are any of my medications: Trittico CR, Seronil 10 mg, Nebilet 5 mg and Caramlo 16mg + 5mg, causing a low pulse?

A low pulse (bradycardia) can be a side effect of several of the medications you mentioned.

Nebilet (nebivolol): It is a beta-blocker used to treat hypertension and heart disease. Beta-blockers are well known for being able to lower the pulse because they reduce the activity of the sympathetic nervous system, leading to a slower heart rate. He is the most likely culprit. Beta-blockers have a strong effect on reducing the pulse.

Caramlo (amlodipine and candesartan): Amlodipine is a calcium channel antagonist and candesartan is an angiotensin II receptor blocker. Amlodipine can affect the pulse, but is less likely to cause significant bradycardia compared to beta-blockers. https://www.gdziepolek.pl/produkty/99940/caramlo-16-mg-5-mg-tabletki/apteki

Trittico (trazodone): It is an antidepressant and can affect the cardiovascular system, but bradycardia is a rare side effect. However, when combined with other medications, it can increase the risk. https://www.gdziepolek.pl/produkty/80016/trittico-cr-tabletki-o-przedluzonym-uwalnianiu/apteki

Seronil (fluoxetine): It is a serotonin reuptake inhibitor (SSRI). It is not typically associated with bradycardia, but it can affect the pulse indirectly, especially in combination with other drugs. https://www.gdziepolek.pl/produkty/70687/seronil-tabletki-powlekane/apteki
