What does it do?

Nortriptyline is used to treat and prevent depression, and may also be used for other conditions including some types of pain.

How should you take it?

Take nortriptyline regularly as directed with a glass of water, usually at night time.

What if you forget a dose?

Take the missed dose as soon as possible. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with nortriptyline including:

• some antihistamines or anti-nausea medicines such as promethazine (e.g. Phenergan®), hyoscine (e.g. Scopoderm®), meclozine (e.g. Sea-legs®)
• cold and flu medicines containing dextromethorphan (e.g. Robitussin Dry Cough Forte®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs (e.g. ecstasy).
