Péthidine pour soulager la douleur

About pethidine

Pethidine is a strong opioid painkiller that is used to treat severe pain, particularly during labour and childbirth, as its effects are shorter-lasting than some of the others.

Pethidine works by acting on the brain and nervous system to reduce how strongly your body feels pain. It also helps you feel more relaxed and drowsy, which can make pain easier to cope with.

Pethidine does not remove the cause of pain, but it changes how pain signals are processed, making the pain feel less severe.

It can be taken by mouth as a tablet, but during labour it is more usually given as an injection.

Common side effects of pethidine include:

• Se sentir malade.

• Être malade (vomissements).

• Sensation de vertige.

• Sentiment d'endormissement ou de somnolence.

• Maux de tête.

• Constipation.

The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any side effects continue or become troublesome.

Si vous ressentez d'autres symptômes qui pourraient être dus au médicament, parlez-en à votre médecin ou à votre pharmacien.

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

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

• Si vous avez des problèmes hépatiques ou rénaux.

• Si vous avez des problèmes de prostate ou des difficultés à uriner.

• If you have any breathing problems, such as asthma or chronic obstructive pulmonary disease (COPD).

• If you have been told you have low blood pressure (hypotension).

• Si vous avez des problèmes de thyroïde ou de glandes surrénales.

• If you have epilepsy.

• Si vous avez un problème au niveau des voies biliaires.

• Si vous êtes constipé depuis plus d'une semaine ou si vous souffrez de troubles inflammatoires de l'intestin.

• If you have a condition causing muscle weakness, called myasthenia gravis.

• Si vous avez récemment subi un traumatisme crânien grave.

• Si vous avez déjà été dépendant de drogues ou d'alcool.

• Si vous avez déjà eu une réaction allergique à un médicament.

• Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

• Read the leaflet inside the pack if you are given one. It explains pethidine and possible side effects.

• Pethidine injections are given by a doctor or nurse, either under the skin or into a muscle.

• During labour, injections can be repeated every few hours if needed.

• For other pain (such as after surgery), injections are usually given every 4 hours if needed.

• Pethidine tablets should be taken exactly as your doctor tells you. The usual dose is 1 to 3 tablets, no more often than every 4 hours.

• If you miss a dose, take it when you remember, then continue as normal. Do not take two doses at the same time to make up for a missed dose.

• Ask your doctor about alcohol. You may be advised not to drink alcohol for a while after having pethidine, as alcohol can increase side effects like dizziness and sleepiness.

• Pethidine can affect driving. Do not drive if you feel drowsy, dizzy, or your reactions are slowed. It is an offence to drive if your ability is impaired.

• If you do drive, carry proof that pethidine has been prescribed for you, such as a prescription slip or patient information leaflet.

• If travelling abroad with pethidine, carry a letter from your doctor, as it is a controlled medicine and may be restricted in some countries.

• Pethidine is only given for a short time. Taking it repeatedly over a longer period can lead to dependence.

• Stopping pethidine after regular use can cause withdrawal symptoms, such as restlessness or irritability.

• This is not a concern if you receive one or two doses during labour.

• Conservez tous les médicaments hors de la portée et de la vue des enfants.

• Conserver dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directes.

How long does it take for pethidine to work?

Pethidine usually starts to work within 10 to 20 minutes when given by injection. Pain relief typically lasts for 2 to 4 hours. The exact timing can vary depending on the dose and the individual.

Does pethidine slow down labour?

Pethidine can slow down labour in some women, particularly if it is given early in labour. It may reduce the strength or frequency of contractions for a short time.

For this reason, it is usually given when labour is more established and is carefully monitored by midwives and doctors.

When is pethidine usually given?

Pethidine is usually given during labour to help manage moderate to severe pain. It is usually given as an injection into your thigh or bottom.
