  • you have serious heart or liver disease
  • you have narrow angle glaucoma (increased pressure in the eye)
  • you have difficulty in passing water
  • you suffer from mania
  • you suffer with porphyria - a genetic disorder of the red blood cells (haemoglobin) causing skin blisters, abdominal pain and brain/nervous system disorders
  • you have had a heart attack in the past 3 months
  • you are taking (now or recently) any other medicines for depression (particularly monoamine oxidase inhibitors [MAOIs] such as moclobemide within the last 3 weeks).

Warnings and precautions

Talk to your doctor or pharmacist before taking Imipramine Hydrochloride if you have:

  • epilepsy (fits) or brain damage
  • severe kidney disease
  • a history of low blood pressure or poor circulation
  • a tumour of the adrenal gland (called phaeochromocytoma or neuroblastoma)
  • an overactive thyroid and are taking medicines to treat a thyroid disorder
  • constipation, especially if you are elderly or bedridden
  • an intolerance to some sugars
  • a withdrawal from alcohol or any anticonvulsive drugs
  • electroconvulsive therapy (ECT) treatment and are taking Imipramine Hydrochloride Oral Solution – you will be carefully supervised.

If you think that any of the above apply to you then tell your doctor before taking Imipramine Hydrochloride Oral Solution.

The use of Buprenorphine together with Imipramine Hydrochloride can lead to serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Imipramine Hydrochloride).

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. This is because these medicines all take about two weeks but sometimes longer to work properly.

You may be more likely to think like this if:

  • you have previously had thoughts about killing or harming yourself.
  • you are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in adults 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.

While you are taking Imipramine Hydrochloride Oral Solution:

  • you will need routine tests (blood, heart and liver tests) from time to time. These will be carried out by your doctor
  • you will be closely monitored as improvement may not occur for the first 2 – 4 weeks of treatment
  • if you already suffer from a panic disorder, you may experience an increase in your feeling of anxiety when you start treatment with Imipramine Hydrochloride Oral Solution. This is usually worse in the first few days and should go away in the first 2 weeks
  • have regular dental check-ups as long term treatment may increase the risk of tooth decay
  • if you need an operation tell your doctor that you are taking the solution
  • contact lens wearers may notice reduced production of tears.

Children taking Imipramine Hydrochloride Oral Solution may have behavioural changes.
