Propranolol - a beta-blocker

About propranolol

Propranolol is a type of حاصرات بيتا used to treat several medical conditions such as anxiety and high blood pressure. It works on the heart and blood vessels.

Propranolol helps ease the physical symptoms of القلق, such as a fast heartbeat and trembling. Similar symptoms to these are also experienced by people with an فرط نشاط الغدة الدرقية. Propranolol quickly relieves these types of symptoms.

It is also the beta-blocker which is commonly prescribed to help prevent migraines. Propranolol can be helpful for people who find other treatments for migraine unsuitable.

Propranolol slows 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 ارتفاع ضغط الدم (فرط ضغط الدم), and helps to prevent إيقاعات القلب السريعة بشكل غير طبيعي (اضطرابات النظم).

Because your heart is using less energy, this helps to reduce chest pain if you have الذبحة الصدرية. Propranolol can also help to protect the heart following a نوبة قلبية.

The most common side effects of propranolol are:

• الشعور بالتعب.

• Cold hands and feet.

• Feeling out of breath.

• Disturbed sleep (insomnia).

• Slow heartbeat.

You you also experience other common side effects such as:

• Erectile dysfunction (impotence).

• Reduce sexual desire (libido).

• Mood changes.

• الصداع.

• Upset stomach.

You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

إذا شعرت بأي أعراض أخرى تعتقد أنها قد تكون بسبب الدواء، تحدث مع طبيبك أو الصيدلي للحصول على مزيد من النصائح.

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

• إذا كنتِ حاملاً، تحاولين الإنجاب أو تقومين بالرضاعة الطبيعية.

• إذا كان لديك أي مشاكل في طريقة عمل الكبد لديك، أو في طريقة عمل الكلى لديك.

• إذا كنت تعاني من انخفاض ضغط الدم أو ضعف الدورة الدموية.

• إذا قيل لك أن لديك نبض قلب بطيء أو انسداد في القلب (نبض قلب بطيء وغير منتظم).

• إذا قيل لك أنك تعاني من ألم في الصدر يسمى ذبحة برينزميتال (ناتجة عن تشنجات في الأوعية الدموية لقلبك).

• Read the manufacturer's printed information leaflet from inside the pack. It will give you more information about propranolol and will provide you with a full list of the side effects which you may experience from taking it.

• Your doctor will tell you what dose of propranolol is right for you, and this information will be printed on the label of the pack to remind you.

• Take propranolol exactly as your doctor tells you to. Propranolol tablets are usually prescribed to be taken in divided doses - so you may be prescribed two, three or four doses to take each day.

  • Propranolol capsules have a more prolonged action and are prescribed to be taken once daily. Swallow the capsule whole with a drink of water - do not chew or open the capsules.

• Propranolol tablets and capsules are available in several different strengths. Each time you collect a fresh supply, it's a good idea to check the strength on the packet to make sure they are the strength you are expecting.

• Try to take your doses at the same times of day each day, as this will help you to remember to take them regularly.

• If you do forget to take a dose of propranolol, take it as soon as you remember unless your next dose is due. If your next dose is due then take the tablet/capsule which is due but leave out the forgotten one. Do not take two doses together to make up for missing one.

• حاول الحفاظ على مواعيدك المنتظمة مع طبيبك. هذا لكي يتمكن طبيبك من متابعة تقدمك.

• Treatment with propranolol can often be long-term. Continue to take the tablets/capsules 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.

• إذا كنت على وشك إجراء عملية جراحية أو علاج أسنان، فمن المهم إخبار الشخص الذي يقوم بالعلاج بأنك تتناول حاصرات بيتا. وذلك لأن بعض المخدرات قد تزيد من خطر الآثار غير المرغوب فيها.

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

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

• إذا اشتريت أي أدوية، تحقق مع الصيدلي من أنها مناسبة لك لتناولها. قد لا تكون بعض الأدوية (بما في ذلك بعض علاجات السعال والبرد والإنفلونزا) مناسبة.

• قد يقدم لك طبيبك نصائح غذائية ونمط حياة حول تناول نظام غذائي صحي، وعدم التدخين، وممارسة التمارين الرياضية بانتظام. إذا كان الأمر كذلك، فمن المهم أن تتبع النصائح التي تُعطى لك.

• احفظ جميع الأدوية بعيدًا عن متناول ورؤية الأطفال.

• احفظه في مكان بارد وجاف، بعيدًا عن الحرارة المباشرة والضوء.
