Beta blockers are a class of medications that reduce the effects of the body’s fight-or-flight response by blocking beta-adrenergic receptors. While they are most commonly prescribed for heart and blood vessel conditions, certain beta blockers have roles in mental health treatment as adjuncts to psychotherapy or other therapies. They do not cure anxiety disorders on their own, but they can help manage physical symptoms such as rapid heartbeat, trembling, and sweating that can interfere with daily functioning, performances, or sleep. When used appropriately, beta blockers are one tool among many to support overall mental health care.

How beta blockers work

  • Block beta-adrenergic receptors located in the heart, blood vessels, and some other tissues. This dampens the sympathetic “alarm” response that causes tachycardia (fast heart rate), palpitations, and tremor.
  • Lower heart rate and blood pressure, which can reduce the bodily sensations that sometimes accompany anxiety or stress.
  • Help control tremor, which can be part of anxiety presentations, making movements steadier in moments of nervousness or performance contexts.
  • In research settings, propranolol has been studied for its potential to influence emotional memory during traumatic experiences, but results are mixed and it is not a standard, first-line treatment for conditions like PTSD.

Common uses and mental health considerations

  • Performance anxiety and stage fright: Propranolol is perhaps the best-known beta blocker for anxiety related to public speaking, stage performances, or timed tests. By blunting physical symptoms, it can help some people feel more in control and able to perform.
  • Tremor linked to anxiety or essential tremor: While not purely a mental health condition, anxiety-related tremor can respond to beta blockers in some individuals, improving steadiness in daily tasks or during social situations.
  • Social anxiety with prominent autonomic symptoms: In select cases, beta blockers may be used to reduce autonomic arousal that occurs in social or evaluative situations.
  • trong> Some clinicians consider low-dose propranolol for nightmares or hyperarousal in PTSD, though evidence is mixed and it is not a universal standard of care. This use requires careful clinical judgment and monitoring.

Typical dosages and how they are determined

Dosage should always be individualized and supervised by a healthcare professional. The following are general ranges commonly discussed for mental health-related uses, but they are not a substitute for professional medical advice.

  • Propranolol (short-acting and non-selective): For performance anxiety, a single dose of 10–40 mg taken about 60–90 minutes before the event is typical. Some people may need up to 80 mg, but higher doses increase the risk of side effects and should be used only under supervision. For ongoing, daytime use in other contexts, clinicians may prescribe lower or higher matching the individual’s needs and tolerance, often in divided doses.
  • Propranolol extended-release: In some cases, a clinician might consider an extended-release formulation for steadier blood levels, but this is less common for performance-related anxiety and more often used for other indications such as tremor or hypertension.
  • Other beta blockers: Cardioselective agents (e.g., metoprolol) may be used in certain situations, but they are less commonly chosen specifically for anxiety-related symptoms. When used, dosing is individualized (for example, small daily doses that may range from 25 mg to 100 mg per day, adjusted for heart rate, blood pressure, and tolerance), and they require monitoring for respiratory effects and other side effects.

Important notes about dosing:

  • Start with the lowest effective dose and titrate slowly under medical supervision.
  • Do not adjust or stop a beta blocker abruptly without discussing it with a clinician, as stopping suddenly can cause rebound symptoms such as rapid heart rate or high blood pressure.
  • Take timing into account for events (e.g., performances) and consider whether you have other medical conditions that affect dosing.

Side effects and monitoring

  • Common and milder effects: Fatigue, dizziness, lightheadedness, cold hands or feet, and slower than normal heart rate (bradycardia). Some people notice sleep disturbances or vivid dreams.
  • Other considerations: Sexual dysfunction can occur in some individuals. Masking of hypoglycemia symptoms may occur in people with diabetes, so monitoring blood glucose is important.
  • Serious but less common risks: Very slow heart rate, significant drop in blood pressure, fainting, or bronchospasm in people with asthma or chronic obstructive pulmonary disease (COPD). These risks are higher with non-selective beta blockers like propranolol, especially at higher doses.
  • People with severe depression or fatigue-related conditions should have careful discussion, since beta blockers can sometimes exacerbate fatigue or mood changes in susceptible individuals.

Monitoring typically includes regular checks of heart rate and blood pressure, assessment of fatigue or dizziness, and evaluation of sleep and mood. Anyone starting a beta blocker should have a plan for follow-up with their clinician to review effectiveness and tolerability, and to adjust dosing if needed.

Interactions with other medications

  • Other blood pressure and heart medications: Additive effects can lower blood pressure or slow the heart rate too much when beta blockers are used with other antihypertensives, calcium channel blockers (like verapamil or diltiazem), or certain antiarrhythmics.
  • Diabetes medications: Beta blockers can mask some signs of low blood sugar. People with diabetes should monitor glucose levels closely and discuss management with their clinician.
  • Medications that affect heart rhythm: Mixing beta blockers with drugs that influence conduction in the heart (such as certain antiarrhythmics) may increase the risk of bradycardia or heart block.
  • CNS depressants: Alcohol and sedating medicines can enhance fatigue or dizziness when used with beta blockers.
  • Other psychotropic medications: While many combinations are safe, clinicians consider potential interactions with antidepressants or antipsychotics, especially in people with complex mental health conditions. Always disclose all medicines and supplements to the prescribing clinician.

Important considerations for patients

  • trong> The decision to use a beta blocker for mental health symptoms depends on the specific symptoms, overall health, and personal preferences. It is most helpful as part of a broader treatment plan that may include psychotherapy, lifestyle changes, and, when appropriate, other medications.
  • trong> Some beta blockers cross the placenta and can appear in breast milk. If you are pregnant, planning pregnancy, or nursing, discuss risks and benefits with your healthcare provider to choose the safest option.
  • trong> Non-selective beta blockers can provoke bronchospasm in people with reactive airways disease. A clinician may prefer cardioselective options at the lowest effective dose, with close monitoring.
  • trong> Dizziness or fatigue can temporarily affect alertness. Avoid driving or operating heavy machinery if you experience these side effects after starting or adjusting a dose.
  • trong> Share your full medical history, including heart problems, kidney or liver issues, thyroid disease, and any known allergies.
  • trong> Carry a current list of all medications, including over-the-counter drugs and supplements. In case of an emergency, clinicians can make safer decisions if they know you are taking beta blockers.
  • trong> Do not stop abruptly. If a clinician determines it is appropriate to stop, a gradual taper is usually required to prevent rebound symptoms.
  • trong> If you have trouble tolerating side effects or if symptoms worsen, contact your clinician promptly to discuss adjustments rather than continuing a dose that feels unsafe.

For additional information about specific beta blockers, you can consult reputable health information resources. See, for example:

If you are considering beta blockers as part of a mental health plan, talk with your healthcare professional about the potential benefits and risks in your case. They can help determine whether a beta blocker is appropriate, tailor a dosing plan, monitor side effects, and coordinate care with any psychotherapy or other treatments you are receiving.
