No: stopping a beta blocker cold can cause serious heart problems. Your body grows extra adrenaline receptors to adapt - remove the blocker and normal adrenaline hits all of them: racing heart, surging pressure, angina flare, and real heart-attack risk in coronary patients.
The whole class carries the rule - metoprolol, propranolol, atenolol, bisoprolol - growing with dose and duration. The safe path is a taper over 1 to 2 weeks or longer, with pulse and pressure watched, and often a substitute drug if side effects drove the quit. Meanwhile: never let the prescription run out (plan refills a week ahead), and name the side effects driving you - fatigue, cold hands, and vivid dreams mostly have fixes short of abandoning protection.

What to do
Common questions
Can you stop taking a beta blocker suddenly?
No - this is one of the genuinely dangerous cold-turkey quits. MedlinePlus is blunt: if you suddenly stop taking metoprolol, you may experience serious heart problems. The mechanism: your body adapts to a beta blocker by growing extra adrenaline receptors - take the blocker away and the extra receptors meet a wall of normal adrenaline, producing rebound effects worse than your original symptoms: racing heart, surging blood pressure, sweating, tremor, angina flares, and in people with coronary disease, a real risk of heart attack and rhythm problems in the days after quitting. The risk applies to the whole class - metoprolol, propranolol, atenolol, bisoprolol - and grows with dose and how long you have taken it. The safe path is a taper: your prescriber steps the dose down over 1 to 2 weeks (sometimes longer), watching your pulse and pressure, and often substituting another drug if the reason for stopping was side effects like fatigue or cold hands. Practical rules meanwhile: never let the prescription simply run out - plan refills a week ahead; if you miss one dose, take it when you remember unless the next is nearly due; and if side effects are driving you to quit, name them - most have fixes that do not require abandoning the heart protection.
