Some medicines can interfere with the action of Doxepin, and Doxepin can sometimes affect the action of other medicines. Check with your doctor if you are taking any of the medicines listed below:

• Monoamine oxidase inhibitors: these must not be used with Doxepin (see ‘What you need to know before you take Doxepin’ section above).
• Other antidepressants, barbiturates (used to treat insomnia) or other sleeping medicines or medicines for anxiety: Doxepin will add to their effects and may cause you to feel sleepy or drowsy.
• Medicines to lower blood pressure.
• Sympathomimetics, such as nasal decongestants (used for colds or hay fever) and bronchodilators (used to treat asthma).
• Cimetidine (used to treat ulcers and other stomach complaints).
• Thyroid hormones (used to treat thyroid disorders).
• Chlorpromazine (used to treat mental illness).
• Sublingual nitrates (used to treat angina and heart failure).

Be careful when drinking alcohol. Alcoholic drinks (wine, beer, spirits) may affect you much more than usual.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Do not take this medicine if you are pregnant, trying to become pregnant or if you are breast-feeding without consulting your doctor.

You may feel sleepy when you take these capsules. Do not drive or work with machinery until this effect has worn off.

Doxepin capsules contain lactose which is a type of sugar. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

This medicine contains less than 1 mmol sodium (23 mg) per capsule, that is to say essentially ‘sodium-free’.

• The usual starting dose is 75 mg daily. This dose may be increased if necessary.
• The maximum recommended dose is 100 mg three times daily.
• The capsules may be prescribed once, twice or three times daily.
• Up to 100 mg can be given as a single dose.

• If you are elderly these doses may be reduced.
• If you are elderly and require an increased dose of the medicine your doctor may wish to see you regularly.
• If you suffer from liver problems you may also be started on a low dose.

• Take this medicine only by mouth.
• Swallow the capsules whole with a drink of water.
• Take the capsules while standing or when sitting upright.
• Do not crush or chew the capsules.

Taking too many capsules at once can be dangerous.

Signs and symptoms of mild overdosage include drowsiness, stupor, blurred vision and excessive dryness of the mouth. Severe overdosage may cause loss of consciousness, reduced breathing rate, convulsions, low blood pressure, unusually fast heart beat or palpitations. If you take too many capsules immediately contact your doctor or nearest hospital Accident and Emergency Department. Do not attempt to drive or work with machinery.

Do not worry. Take your usual dose at the next correct time. Do not take a double dose to make up for a forgotten capsule.

You should always check with your doctor before you stop treatment. Your doctor may want you to reduce gradually the amount you are taking before stopping the medicine completely. This may help to prevent a recurrence of the original trouble and reduce the chance of withdrawal effects such as insomnia, irritability and excessive sweating.

• You may take Doxepin for 2–3 weeks before you start to feel better.
• You must keep taking Doxepin to help you get better.
• See your doctor before your capsules run out.
• Even if you begin to feel better, keep taking your capsules. You may need to keep taking them to stay well.

Tell your doctor if you have taken all your medicine and you still feel unwell or if you feel worse.

If you are depressed and/or have anxiety disorders you can sometimes have thoughts of harming or killing yourself. These may be increased when first starting antidepressants, since these medicines all take time to work, usually about two weeks but sometimes longer.

You may be more likely to think like this:

• if you have previously had thoughts about killing or harming yourself.
• if you are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in adults aged less than 25 years with psychiatric conditions who were treated with an antidepressant.

If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away. You may find it helpful to tell a relative or close friend that you are depressed or have an anxiety disorder, and ask them to read this leaflet. You might ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behaviour.

Bone fractures:

An increased risk of bone fractures has been observed in patients taking this type of medicine.
