About buprenorphine

Buprenorphine is a مسكن أفيوني قوي that is used to treat severe pain. It works on your nervous system and brain to reduce the amount of pain you feel.

It is also used in the treatment of some drug addictions. When it is used for this purpose, different brands of buprenorphine tablets are used.

Buprenorphine is available as:

• Injection.

• أقراص.

• لاصقات جلدية.

Tablet and injection forms of buprenorphine are used to ease short-term (acute) pain, such as the type of pain you get after an operation.

Skin patches are used for long-term (chronic) pain. The patches release buprenorphine slowly and evenly over several days.

Common side effects of buprenorphine include:

• الشعور بالدوار.

• الشعور بالنعاس أو الخمول.

• رؤية ضبابية.

• الشعور بالغثيان.

• التقيؤ.

• الصداع.

• الإمساك.

• Itchy rash where the patch has been.

You will find a full list in the manufacturer's information leaflet supplied with your medicine.

Some medicines are not suitable for people with certain conditions. Before taking buprenorphine it is important that your doctor knows:

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

• إذا كنت تعاني من مشاكل في الكبد أو الكلى.

• إذا كنت تعاني من مشاكل في البروستاتا أو أي صعوبات في التبول.

• If you have any breathing problems, such as الربو أو مرض الانسداد الرئوي المزمن (COPD).

• If you have been told you have انخفاض ضغط الدم (انخفاض التوتر الشرياني).

• إذا كان لديك أي مشاكل في الغدة الدرقية أو الغدد الكظرية.

• If you have الصرع.

• إذا كان لديك مشكلة في القناة الصفراوية.

• إذا كنت تعاني من الإمساك لأكثر من أسبوع أو لديك مشكلة التهاب الأمعاء.

• If you have a condition causing muscle weakness, called الوهن العضلي الوبيل.

• إذا كنت قد اعتمدت في أي وقت مضى على المخدرات أو الكحول.

• إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.

• إذا كنت تتناول أي أدوية أخرى. يشمل ذلك أي أدوية تتناولها والتي يمكن شراؤها بدون وصفة طبية، بالإضافة إلى الأدوية العشبية والمكملات الغذائية.

  • It is particularly important that you let your doctor know if you are taking any other strong painkillers or over-the-counter painkillers containing codeine (for example, co-codamol).

• Read the patient information leaflet that comes with your medicine. It explains how the tablets work and lists possible side effects.

• Take buprenorphine exactly as prescribed. Your doctor or pharmacist will tell you how many tablets to take and when. The dose will also be shown on the label.

  • Most people are prescribed 200-400 micrograms every 6-8 hours, depending on pain.

• Place the tablet under your tongue and let it dissolve fully. This may take a few minutes. Do not chew it or swallow it whole.

• You can take buprenorphine with or without food.

• If you forget a dose, take it as soon as you remember, then continue as normal. Do not take two doses at the same time.

• Read the patient information leaflet in the pack. It explains how to use your patch and lists possible side effects.

• Check how often to change your patch. Different brands are changed at different times. Follow the instructions on the label or leaflet, or ask a pharmacist if you’re unsure.

• Apply the patch to clean, dry, non-hairy skin on your upper body, such as your chest, upper back, or outer arm. Avoid irritated skin.

• Change patches as directed:

  • Seven-day patches (for example, BuTrans®): change once a week on the same day. Use a different area of skin each time and avoid reusing the same spot for 3 weeks.

  • Twice-weekly patches (for example, Transtec®): change every 3–4 days on the same days each week. Avoid using the same area for at least 6 days.

  • Three-day patches (for example, Hapoctasin®): change every 3 days and rotate skin sites, avoiding the same area for at least 6 days.

• Heat can increase the dose absorbed. Fever, electric blankets, hot water bottles, or very hot baths or showers can cause more medicine to enter your body. Tell your doctor if you develop a fever or feel unusually sleepy or dizzy.

• Do not use more patches than prescribed. Always remove the old patch before applying a new one. Signs of overdose include very small pupils, slow or difficult breathing, and extreme drowsiness. Get urgent medical help if this happens.

• Skin irritation: If a rash develops, do not use that area again until it has healed. Speak to your doctor if the rash is severe.

• Bathing and swimming are allowed, but avoid overheating. If a patch falls off, do not re-attach it — apply a new one instead.

• Dispose of used patches safely. Fold the patch in half with the sticky sides together and throw it away as instructed to prevent accidental contact.

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

• Ask your doctor about alcohol. You may be advised not to drink alcohol, as it can increase side effects such as dizziness and drowsiness.

• Check your prescription each time. Buprenorphine comes in different brands and strengths. Make sure you receive the one you expect. Ask a pharmacist if you’re unsure.

• Driving may be affected. Buprenorphine can slow your reactions. It is illegal to drive if you are impaired. If you do drive, carry proof that the medicine has been prescribed for you.

• If you are travelling abroad take a letter from your doctor explaining your prescription. Buprenorphine is a controlled drug and subject to legal restrictions in some countries.

• Tell healthcare professionals you are taking buprenorphine before any surgery or dental treatment.

• Check other medicines first. Some medicines can increase side effects when taken with buprenorphine. Ask a pharmacist before taking anything new.

• Use for the shortest time needed. Long-term use can lead to dependence and withdrawal symptoms when stopped. Speak to your doctor or pharmacist if you are concerned.

• احفظ جميع الأدوية بعيدًا عن متناول ورؤية الأطفال.

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