Pethidine for pain relief

About pethidine

Strong opioids are medicines used to treat severe pain. Although there are a number of strong opioids, pethidine is the opioid that has been traditionally used during childbirth, as its effects are shorter-lasting than some of the others. It works on your nervous system and brain to reduce the amount of pain you feel. Pethidine can be taken by mouth as a tablet, but during labour it is more usually given as an injection.

Before having pethidine

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 are given pethidine, it is important that your doctor knows:

• If you are pregnant (other than during labour) or breastfeeding.

• Wenn Sie Leber- oder Nierenprobleme haben.

• Wenn Sie Prostataprobleme oder Schwierigkeiten beim Wasserlassen haben.

• Wenn Sie Atemprobleme haben, wie z. B. Asthma oder chronisch obstruktive Lungenerkrankung (COPD).

• Wenn Ihnen gesagt wurde, dass Sie einen niedrigen Blutdruck (Hypotonie) haben.

• Wenn Sie Probleme mit Ihrer Schilddrüse oder den Nebennieren haben.

• Wenn Sie Epilepsie haben.

• Wenn Sie ein Problem mit Ihrem Gallengang haben.

• Wenn Sie seit mehr als einer Woche unter Verstopfung leiden oder ein entzündliches Darmproblem haben.

• Wenn Sie an einer Muskelschwäche leiden, die Myasthenia gravis genannt wird.

• Wenn Sie kürzlich eine schwere Kopfverletzung erlitten haben.

• Wenn Sie jemals von Drogen oder Alkohol abhängig waren.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

• Wenn Sie andere Arzneimittel einnehmen. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.
  

How pethidine is given

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

• If you have been prescribed pethidine injection, this will be given to you by your doctor or nurse. It will be injected under your skin or into a muscle. The injections can be repeated every few hours during labour, if needed. If you are being given pethidine for other types of pain (such as after an operation), the injection can be repeated every four hours.

• If you have been prescribed pethidine tablets, take the tablets exactly as your doctor has told you to. The usual dose of pethidine is between one and three tablets. The dose should not be repeated more frequently than every four hours. If you forget to take a dose, take it as soon as you remember and then continue taking your doses every four hours from that point. Do not take two doses together to make up for a forgotten dose.

Das Beste aus Ihrer Behandlung herausholen

• Ask your doctor for advice before drinking alcohol. Your doctor may recommend that you do not drink alcohol for a while after you have had pethidine because it increases the possibility of side-effects such as feeling dizzy and sleepy.

• If you are a driver, please be aware that pethidine is likely to affect your reactions and ability to drive. It is an offence to drive while your reactions are impaired. Even if your driving ability is not impaired, should you drive, you are advised to carry with you some evidence that the medicine has been prescribed for you - a repeat prescription form or a patient information leaflet from the pack is generally considered suitable.

• If you are planning a trip abroad and need to take pethidine with you, you are advised to carry a letter with you from your doctor to explain why you have been prescribed it. This is because pethidine is classed as a 'controlled drug' and is subject to certain restrictions.

• You will not be given pethidine tablets for longer than is necessary. This is because repeatedly using pethidine over a period of time can lead to your body becoming dependent on it. When you then stop taking it, it will cause withdrawal symptoms such as restlessness and irritability. If you are concerned about this, discuss it with your doctor or pharmacist. This will not become a problem if you are receiving a dose or two of pethidine during labour.

Can pethidine cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with pethidine. 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.

Wenn Sie andere Symptome haben, von denen Sie glauben, dass sie auf das Arzneimittel zurückzuführen sind, sprechen Sie mit Ihrem Arzt oder Apotheker.
