You have been given this leaflet because you have been prescribed Duloxetine tablets for pain relief. This leaflet has been produced to give you general information about your treatment. Most of your questions should be answered by this leaflet. It is not intended to replace the discussion between you and your doctor, but may act as a starting point for discussion. If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team caring for you.
What is Duloxetine and what is it used for?
Duloxetine can be used to treat different types of chronic pain. It is especially good for nerve pain, such as burning, shooting or stabbing pain and for pain that keeps you awake at night. Duloxetine belongs to the group of medicines called Serotonin Noradrenergic Reuptake Inhibitors (SNRI) that are also used to treat depression. Duloxetine works by increasing the amount of specific nerve transmitters in the nervous system, this then reduces the pain messages arriving in the brain.
When should I take it?
It is best to take Duloxetine at the same time each day, usually in the morning. If you find it makes you drowsy try taking it in the evening.
How do I take Duloxetine tablets?
The tablets should be swallowed whole with water on an empty stomach.
How long will it take to work?
You may feel a slight effect after 1 week but it may take up to 1 month to feel the full effect. The dose may need to be increased to gain maximum effect; your doctor / specialist nurse will advise you regarding this. Duloxetine does not always work for everyone, however if you do not feel any benefit from this medication, do not stop it suddenly but speak to your doctor first.
Can there be any side effects or risks?
The most common side effect for this medicine is drowsiness, which usually lasts a few days. If the drowsiness occurs, you should not drive or operate machinery, until the drowsiness stops. You must advise the DVLA if you are taking medication which may affect your driving. Other common side effects include dry mouth, diarrhoea and constipation. If you become constipated, tell your doctor/nurse/pharmacist and they will be able to recommend how you can change your diet or which medicine to take to treat your constipation. If you experience any other side effects (anything unusual for you within a few days of starting the medicine) you should stop taking Duloxetine and inform your doctor.
Can I drink alcohol?
The combination of Duloxetine and alcohol can cause significant drowsiness if you have just started on this medicine or the dose has recently been increased. You are advised not to drink alcohol when you first start this medicine and while the dose is being increased. Once you are on a stable dose and the drowsiness caused by the Duloxetine stops, you may drink alcohol.
Can I take other medicines together with Buprenorphine?
Duloxetine can interact with other medicines, e.g. warfarin, tramadol and herbal products. Always tell your doctor, nurse or pharmacist which other medicines you are taking or buying, so they can make sure there are no interactions between your medicines. Please read the information leaflet. Share the information it contains with your partner and family (if you wish) so that they can be of help and support. There may be information they need to know, especially if they are taking care of you following this examination.
What dose should I take?
The healthcare team caring for you will decide on the dose that you are prescribed, this may be decreased or increased over a period of time by your GP or consultant.
What do I do If I want to stop taking duloxetine?
Do not suddenly stop taking this medication unless in an emergency situation.
If you experience any side effects whilst taking your Duloxetine (apart from drowsiness which is usually temporary), please reduce the dose back to the level where you had no side effects or discontinue this medicine; however, to discontinue this medicine it is best to reduce the dose slowly over 1 – 2 weeks by missing out a dose every few days.
Seek guidance from the healthcare team looking after you or your GP prior to changing your dose.
If you are concerned about any immediate potentially serious side effects such as a rash or swelling, speak to your GP/Pharmacist/Nurse as you may need to stop this medicine immediately. In this situation if you have any doubts/concerns and cannot speak to a health care professional, stop the medicine then seek medical advice at the earliest available opportunity. Some people can stop this medicine suddenly and have no problems; however some people may get withdrawal symptoms if it is stopped suddenly such as insomnia, headache, flu syndrome, anxiety etc which should only last a few days. These symptoms are more likely to occur if people have been on this medicine for more than a few months.
What do I do if I take too many tablets?
If you have taken too many tablets immediately seek medical advice from your GP or attend your local Emergency Department.
What happens afterwards?
After beginning this medication, you will be followed by a specialist nurse. This is usually done with a telephone review.
