Beta blockers Beta blockers are used to treat high blood pressure, anxiety, angina, glaucoma and other conditions.
Beta blockers have the opposite effect to reliever inhalers which act as beta stimulants.
Beta blockers come in two main forms. Beta blocker tablets eg propanolol, atenolol Prescribed for high blood pressure, heart problems and anxiety. Eye drops eg bexaxolol Prescribed for glaucoma. Eye drops have caused severe asthma symptoms in some people. The Committee on the Safety of Medicines has advised doctors that beta blockers should not be used by patients with asthma, unless no alternative treatment is available.
