You have been given this leaflet because you have been prescribed amitriptyline. This leaflet has been produced to give you general information about your medication. 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 Amitriptyline and what is it used for?
Amitriptyline is used to treat many types of persistent pain. It is especially good for nerve pain, such as burning, shooting or stabbing pain and for pain that keeps you awake at night. Amitriptyline belongs to the group of medicines called tricyclic anti-depressants that are also used to treat depression. The dose of amitriptyline needed for pain relief is usually lower than that prescribed for depression.
You may notice that information from the manufacturer does not mention pain; however amitriptyline has been used to treat pain for many years. It is an unlicensed medication prescribed for the management of neuropathic pain. Amitriptyline works by increasing the amount of specific nerve transmitters in the nervous system, reducing pain messages arriving in the brain.
How do I take Amitriptyline?
- The tablets should be swallowed whole with water.
- Amitriptyline may be taken on an empty or full stomach.
- You will be told how much to start taking and when to increase the dose. The table at the end of the leaflet will help you remember when to increase the dose.
- Do not take more than prescribed.
- It is best to take amitriptyline in the evening. Start by taking it 1 hour before going to bed. If you find that you feel drowsy the next morning, try taking it earlier in the evening.
How long will it take to work?
Every patient is different. You may notice some initial benefit within 2 weeks. However it may take up to 2 months to gain maximum effect and your doctor may need to increase the dose. Amitriptyline does not work for everyone. If you do not feel any improvement in your pain, do not suddenly stop taking the tablets but speak to your doctor.
Are there side effects from taking Amitriptyline?
Most side effects are mild and it is expected that they stop after a few doses. Common side effects include drowsiness, dizziness, dry mouth, constipation and sweating. If you have these side effects and they are severe, contact your doctor or pharmacist for advice.
Less common side effects include fainting, trembling, irregular heartbeat, blurred vision or problems passing water. If any of these side effects occur, contact your doctor or pharmacist for advice.
Can I drink Alcohol?
Alcohol increases the sedative effects of amitriptyline; do not to drink alcohol when you start taking it. Once settled on a steady dose, you may drink alcohol in moderation but it may make you more drowsy than normal.
What should I tell the doctor?
Speak to the doctor if you:
- are allergic to any drugs or are taking any other medicines or herbal medicines
- are pregnant or breastfeeding, or if you are planning to become pregnant in the future
- have had a heart attack recently or have any heart problems
- have a history of epilepsy or fits
- have glaucoma
- have difficulty in passing water
- have thyroid disease
- have or have had a mental health problem
- are taking an anti-depressant medicine, especially one called a Monoamine oxidase inhibitor (MAOI)
- Do not run out of amitriptyline
- Remember to ask for a repeat prescription before your tablets are finished.
If you have taken too many tablets immediately seek medical advice from your GP or attend your local Hospital Emergency Department. An overdose of amitriptyline can be fatal.
Can I drive?
Do not drive if Amitriptyline causes you to be drowsy. You must advise the DVLA if you are on medicines that may affect your driving.

What do I do if I forget to take a regular dose?
If you forget to take a regular dose please take the following action:
- Take it as soon as you remember.
- If you only take one dose at bedtime and you miss the dose, do not take the medicine in the morning. Wait until the next night and skip the missed dose.
- Do not take two doses together.
