Nebivolol
Prescription status is set country by country — the label where you live is the one that applies.

Nebivolol is a highly cardioselective beta blocker that also promotes nitric oxide release from the vessel lining. It slows the heart and reduces its workload while allowing blood vessels to relax. Where it is marketed, it is prescription-only and used for hypertension; where a label also carries heart failure, as in the EU and UK, it is restricted to elderly patients.
A usual adult range, not a national label — the dose and the timing differ by country and by product.
Approved uses differ by country — some of these may be off-label or unapproved where you live.
Food makes no difference to it. It is never stopped abruptly, because the heart becomes temporarily oversensitive to adrenaline and chest pain or rhythm disturbance can follow; changes are made by a doctor and tapered. Slowing of the heart rate is the expected pharmacology, not a fault, but it can go further than intended, especially alongside other drugs that slow conduction.
A pulse that stays slow, fainting or near-fainting, growing breathlessness or swelling ankles are reasons to see a doctor, as is any run of missed doses that has left the drug effectively stopped.
