Oxprenolol - a beta-blocker

About oxprenolol

Oxprenolol belongs to the group of medicines known as beta-blockers. It is used for a number of different problems. It is prescribed on a continuous basis to treat high blood pressure (hypertension), and to prevent angina pain and also abnormally fast heartbeats (arrhythmias). It can also be prescribed for short periods of time to ease some symptoms of anxiety.

Beta-blockers slow down the activity of your heart by stopping messages sent by some nerves to your heart. It does this by blocking tiny areas (called beta-adrenergic receptors) where the messages are received by your heart. As a result, your heart beats more slowly and with less force. This allows the pressure of blood within your blood vessels to be reduced if you have high blood pressure, and helps to prevent abnormally fast heart rhythms. Because your heart is using less energy, it also helps to prevent chest pain if you have angina attacks.

Anxiety can cause physical symptoms such as a fast heartbeat and the sensation of having a 'thumping heart' (palpitations). Because oxprenolol slows your heart rate, it can help to ease these symptoms. Oxprenolol will not help to relieve the emotional symptoms of anxiety such as stress and fear - these will be treated separately.

Before taking oxprenolol

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking oxprenolol it is important that your doctor knows:

• Si está embarazada o en periodo de lactancia.

• Si padece asma o cualquier otro trastorno respiratorio.

• Si tiene algún problema con el funcionamiento de su hígado.

• Si tiene la tensión baja o mala circulación.

• Si padece diabetes (diabetes mellitus).

• Si tiene un problema cutáneo llamado psoriasis.

• Si padece una enfermedad que causa debilidad muscular, llamada miastenia gravis.

• Si le han dicho que tiene ritmo cardiaco lento, insuficiencia cardiaca o bloqueo cardiaco (ritmo cardiaco lento e irregular).

• Si le han dicho que tiene dolor torácico causado por espasmos de los vasos sanguíneos del corazón, lo que se denomina angina de Prinzmetal.

• Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que pueda adquirirse sin receta, así como medicamentos a base de plantas y complementarios.

• Si ha tenido alguna vez una reacción alérgica a un medicamento, o si ha tenido alguna otra reacción alérgica grave.

How to take oxprenolol

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about oxprenolol and will provide you with a full list of the side-effects which you may experience from taking it.

• Take oxprenolol exactly as your doctor tells you to - the directions will be printed on the label of the pack of tablets to remind you about what the doctor said. Your dose will depend upon the type of tablets you are taking and the reason for you taking them but, as a guide, it is usual to take oxprenolol one, two, or three times daily. There are different strengths of tablet available, so each time you collect a fresh supply it is a good idea to check to make sure you receive the strength you are expecting. If you have any questions, please ask your pharmacist to advise you.

• Swallow the tablet with a drink of water. You can take oxprenolol either before or after meals, but try to take your doses at the same time of day each day, as this will help you to remember to take them regularly.

• If you are taking a modified-release form of oxprenolol, it is important that you swallow the tablets whole. Do not chew or crush them.

• Si olvida tomar una dosis, tómela en cuanto se acuerde (a menos que sea casi la hora de la siguiente dosis, en cuyo caso omita la dosis olvidada). No tome dos dosis juntas para compensar la dosis olvidada.

Aproveche al máximo su tratamiento

• Procure acudir a las citas periódicas con su médico. Así podrá comprobar su evolución.

• Treatment with oxprenolol is usually long-term (except if you are taking it for anxiety). Continue to take the tablets unless your doctor tells you to stop. Stopping treatment suddenly can cause problems in some people, so your doctor may want you to reduce your dose gradually if this becomes necessary.

• Si va a someterse a una operación o a un tratamiento dental, es importante que informe a la persona que vaya a realizar el tratamiento de que está tomando un betabloqueante. Esto es especialmente importante si es probable que le administren anestesia.

• If you drink alcohol, ask your doctor for advice about taking oxprenolol and alcohol. Alcohol will add to the blood pressure-lowering effect of oxprenolol which will make you feel dizzy and so may not be recommended for you.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take with oxprenolol. Some medicines (including some anti-inflammatory painkillers, and cold or flu remedies) may not be.

• Es posible que su médico le dé consejos dietéticos y de estilo de vida sobre cómo seguir una dieta sana, no fumar y hacer ejercicio con regularidad. Si es así, es importante que siga los consejos que le den.

• If you have diabetes, oxprenolol can block the symptoms of low blood sugar. Your doctor will advise you about this.
