1. WHAT DOXEPIN IS AND WHAT IT IS USED FOR

The name of this medicine is Doxepin 25mg and 50mg Capsules, Hard. The active ingredient is doxepin (as hydrochloride). Doxepin is an antidepressant. It is one of a group called tricyclic antidepressants.

Your doctor has decided that this medicine is suitable for treating your depression. Depression is a clinical illness. If you have been feeling sad, tearful or unable to enjoy life as you used to, Doxepin may help you to feel better. It may also help if you have difficulty sleeping because of your depression. If you are not sure why you are on these capsules, ask your doctor.

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE DOXEPIN
Do not take Doxepin Capsules if:
  • You have ever had an allergic reaction to tricyclic antidepressants, doxepin, or any of the other ingredients of this medicine (listed in section 6).
  • You have serious liver problems

If you take more Doxepin Capsules than you should

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.

If you stop taking Doxepin Capsules

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.

  • 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.

    or
  • You feel worse.

If you have any further questions on the use of this medicine, ask your doctor, or pharmacist or nurse.

4. POSSIBLE SIDE EFFECTS

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Thoughts of suicide and worsening of your depression or anxiety disorder.

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.
