1 What Imipramine tablets are and what they are used for

Imipramine belongs to a group of medicines called tricyclic antidepressant drugs. These medicines alter the levels of chemicals in the brain to relieve the symptoms of depression.

Imipramine is used:

  • to treat the symptoms of depression.
  • for the relief of bed-wetting at night by children.

2 Before you take

Do not take Imipramine tablets and tell your doctor if you or your child (if they are the patient):

  • are allergic (hypersensitive) to imipramine, other tricyclic antidepressants or any of the other ingredients (see section 6). The 10mg tablets contain sunset yellow (E110) and aramanth (E123) and the 25mg tablets contain propylhydroxybenzoate (E216) and methylhydroxybenzoate (E218) which may cause allergic reactions which could be delayed
  • have heart disease such as irregular heart beats, heart block or have recently had a heart attack
  • suffer from periods of increased and exaggerated behaviour (mania)
  • have severe liver disease
  • suffer with porphyria (a genetic disorder of the red blood cells haemoglobin causing skin blisters, abdominal pain and brain/nervous system disorders)
  • are not able to pass water
  • have increased pressure in the eye (glaucoma)
  • are taking monoamine oxidase inhibitors (MAOI) or you have taken MAOIs within the previous 14 days for depression
  • if the child is under 6 years old.

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 young adults (less than 25 years old) 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.

Check with your doctor or pharmacist before taking Imipramine tablets if you or your child (if they are the patient):

  • have any psychiatric disorder (eg schizophrenia or manic depression)
  • are withdrawing from alcohol or medicines used to treat fits
  • have ever had glaucoma or an enlarged prostate gland
  • have an overactive thyroid gland and are taking medicines to treat a thyroid disorder
  • have a history of epilepsy or brain damage
  • have low blood pressure or poor circulation
  • have severe kidney disease
  • have a tumour of the adrenal gland (eg phaeochromocytoma or neuroblastoma)
  • suffer from panic attacks
  • suffer from long term constipation
  • wear contact lenses
  • are being given electroconvulsive therapy (ECT)
  • are due to have any surgery, including dental, that involves an anaesthetic.
