Beta-Blocker Discontinuation Symptom Profile
Abrupt metoprolol discontinuation can trigger rebound sympathetic activation. Typical manifestations include increased heart rate and elevated blood pressure. [1]
Common Symptoms
- Palpitations or tachycardia that may feel subjectively like a “racing heart.” [1]
- Blood pressure elevation, which can present with headache or feeling “throbbing” pressure. [1]
- Agitation or nervousness related to adrenergic overactivity. [1]
- Headache. [2]
- Nausea. [2]
- Tremor and diaphoresis (sweating) can occur as part of a withdrawal-type sympathetic surge. [2]
Cardiovascular Symptoms That Can Signal Clinically Important Rebound
- Chest pain or angina symptoms. [1]
- New or worsening arrhythmia symptoms (for example, irregular pounding or skipped beats). [1]
Symptom Pattern in Relation to Baseline Heart Rate
Normal baseline heart rate before stopping does not eliminate risk of rebound tachycardia after metoprolol withdrawal. [1]
Timing After Abrupt Stop
Withdrawal-type symptoms have been described after cessation of antihypertensive agents that include beta-blockers, with symptoms reported within the first days after stopping in clinical literature reviews. [2]
Safety Considerations for Patients With Mild Hypertension
Rebound sympathetic activation can produce blood pressure elevation even when hypertension is mild at baseline. [1]
Actions to Reduce Risk
Abrupt discontinuation of beta-blockers is associated with rebound phenomena, so discontinuation is generally managed with a gradual dose reduction rather than stopping suddenly. [1]
When Urgent Care Evaluation Is Indicated
Urgent evaluation is indicated for chest pain, severe or sustained blood pressure elevation with symptoms, syncope, or symptoms suggesting arrhythmia. [1]
