Y51: Drugs primarily affecting the autonomic nervous system

Y51.7: Beta-adrenoreceptor antagonists, not elsewhere classified

Beta-adrenoreceptor antagonists, also known as beta-blockers, are medications often used to treat conditions associated with the heart and blood vessels. Typically, they interfere with the binding of adrenaline to beta receptors, slowing down the heart rate and reducing the blood pressure. This medication code, Y51.7, is generally associated with adverse effects not classified elsewhere. These adverse effects can occur when your body does not respond as expected to these medications. Common side effects include fatigue, cold hands or feet, and slow heartbeat. More serious effects like shortness of breath, swelling of the hands or feet, or sudden weight gain can also occur. These side effects are usually a result of the medicine affecting the body's normal functions, and they can appear at any time while taking the medication. Please note this code does not refer to a disease condition, but to undesired effects linked to the use of beta-adrenoreceptor antagonists.
