Beta-blockers can sometimes cause breathing difficulties for people with asthma and may reduce the effectiveness of rescue inhalers that relieve asthma symptoms. Still, in some cases, doctors may prescribe them for individuals with asthma.
Beta-blockers are medications that help manage certain conditions by blocking the effects of adrenaline. They can treat conditions such as high blood pressure, cardiovascular disease, and anxiety.
However, for people with asthma, the use of beta-blockers can be a topic of concern due to their potential impact on the lungs and breathing.
In this article, we explore whether people with asthma can take beta-blockers, what the risks are, and which ones a doctor might consider. We also look at other ways to treat asthma and answer some frequently asked questions.
Some people with asthma may be able to use beta-blockers. Doing so requires important discussions with a doctor and close medical monitoring due to the possible dangers linked to these medications.
A doctor does not usually prescribe beta-blockers to people with asthma. However, if they have asthma alongside another medical condition for which treatment with a beta-blocker would help, a doctor will assess the possible risks and decide whether it is a good fit.
In some cases, certain beta-blockers can
Doctors will carefully select the beta-blocker type, start someone at a low dose, and closely monitor them to help mitigate risks. Always consult a healthcare professional before trying any new medications.

Beta-blockers work by blocking the effects of hormones such as adrenaline, which can lead to a decrease in heart rate and blood pressure. While this may be beneficial for many medical conditions, it can pose risks for people with asthma.
One of the main concerns with beta-blockers use in asthma is their potential to
Bronchoconstriction can lead to a worsening of asthma symptoms, such as:
- wheezing
- shortness of breath
- coughing
- increased frequency and severity of asthma attacks
Beta-blockers target beta receptors in the lungs. They can interfere with the body’s ability to dilate the airways in response to triggers such as allergens or exercise. Ultimately, it can lead to an increase in
For individuals with asthma who require beta-blocker therapy for other medical conditions, a doctor may
Selective beta-blockers — also known as second-generation beta-blockers — are cardioselective, meaning they primarily target beta-1 (B1) receptors.
These medications are less likely to cause breathing issues because they target B1 receptors in the heart. However, when taken in certain amounts, they may affect receptors in the lungs.
Selective beta-blockers
- atenolol (Tenormin)
- bisoprolol (Zebeta)
- esmolol (Brevibloc)
- metoprolol (Lopressor)
- nebivolol (Bystolic)
When individuals cannot use beta-blockers, a doctor may recommend alternative medications or treatment strategies to minimize the risk of adverse effects on the lungs.
Several other measures, in addition to medications, can help people with asthma effectively manage their symptoms and improve their overall quality of life.
These may include:
- avoiding triggers
- trying natural remedies
- using inhalers correctly
- following an asthma action plan
- receiving regular monitoring
For individuals with asthma, it is important to monitor reactions to taking medications for other conditions and to consult a physician if a prescription or over-the-counter (OTC) medication is causing asthma flare-ups.
Below are answers to common questions about beta-blockers and asthma.
Why are beta-blockers contraindicated in asthma?
Beta-blockers can tighten the airways (known as bronchoconstriction) and worsen asthma symptoms. They can also lead to increased airway resistance and affect breathing.
Do beta-blockers cause respiratory problems?
Yes, beta-blockers can cause respiratory problems, particularly in people with preexisting respiratory conditions such as asthma.
What is a long-acting beta-blocker for asthma?
Long-acting beta-blockers are medications that block the effects of adrenaline for a longer period of time. They are usually taken once a day.
Is labetalol safe for people with asthma?
Labetalol is a non-selective beta-blocker that may pose risks for people with asthma due to its potential to tighten airways and increase asthma symptoms. Healthcare professionals do not usually prescribe labetalol for people with asthma.
The use of beta-blockers in people with asthma requires careful consideration of the potential risks and whether they outweigh the benefits. While beta-blockers can effectively treat certain medical conditions, they may exacerbate respiratory symptoms in individuals with asthma.
Healthcare professionals carefully evaluate whether beta-blocker therapy is appropriate for people with asthma on a case-by-case basis.
Effective asthma management requires a comprehensive approach that includes medication management, avoidance of triggers, proper inhaler technique, and regular monitoring by a healthcare professional. Alternative treatments may be available.
