It is used to treat:
- major depression - the 10 mg and 25 mg tablets can be used at any stage in treatment, however, the 50 mg tablets are approved only for maintenance treatment (i.e. after symptoms have improved).
- bed wetting, provided there is no physical cause (e.g. problems with the bladder).

How it works
Amitriptyline belongs to a group of medicines called tricyclic antidepressants (TCAs). TCAs work by correcting the imbalance of certain chemicals in the brain. These chemicals, called amines, are involved in controlling mood. By correcting this imbalance, TCAs can help relieve the symptoms of depression.
There is no evidence that this medicine is addictive.
Use in children
Amitriptyline should not be used in children and adolescents aged less than 18 years for the treatment of depression. The safety and efficacy have not been satisfactorily established.

How to take this medicine
Follow carefully all directions given to you by your doctor. Their instructions may be different to the information in this leaflet.
How much to take
Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
For depression, it is recommended that the dose is started at a low level and increased gradually. When satisfactory improvement has been reached, the dose should be reduced to the lowest amount that will maintain relief of symptoms.
For bed wetting, the doses recommended are low compared with those used for depression.
Do not stop taking your medicine or change your dosage without first checking with your doctor.
How to take it
Swallow the tablet(s) whole with a glass of water.
When to take it
Amitriptyline may be taken as a single dose (e.g. at bedtime) or as divided doses (e.g. three times a day), your doctor will advise you when to take it.
Take your dose(s) at the same time each day, this will have the best effect and will also help you remember when to take it.
It does not matter if you take it before, with or after food.
How long to take it for
Some people notice an improvement in their depressive symptoms after 3 or 4 days however it may take up to 4 weeks.
Most children respond to bed wetting treatment in the first few days.
Please note your doctor may ask you to continue taking amitriptyline even after your symptoms have improved. It is important you continue taking your medicine for as long as your doctor tells you.
Make sure you have enough to last over weekends and holidays.
If you forget to take it
If you take more than one dose a day and it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take it as soon as you remember and then go back to taking your medicine as you would normally.
However, if you only take one dose a day at bedtime, ask your doctor for advice regarding missed doses, as taking it another time when you remember may mean you have difficulty waking up in the morning or experience drowsiness in the day.
Do not take a double dose to make up for missed doses.
This may increase the chance of you experiencing side effects.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.
If you take too much (overdose)
If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively, go to the Accident and Emergency department at your nearest hospital.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
