1. What Imipramine Tablets are and what they
are used for
These tablets are available in two different strengths containing either
10 mg or 25 mg of the active ingredient, imipramine. Imipramine
belongs to a group of medicines called antidepressants.
Imipramine Tablets are used to treat depressive illnesses in adults.
They can also be used in children to help treat bed wetting.

2. Before you take Imipramine Tablets
Some people must not take these tablets. Do not
take these tablets if:
• You know you are allergic to imipramine, or to any other similar
antidepressants, or to any of the other ingredients (these are
listed in section 6)
• You have recently had a heart attack, you suffer from
heart block or an irregular heartbeat
• You have periods of mania (feeling elated or over-excited)
• You have severe liver disease
• You have glaucoma (increased pressure inside the eye)
• You have problems passing urine
• You are pregnant or breastfeeding (unless considered absolutely
essential by your doctor)
• You are taking, or have taken, a monoamine oxidase inhibitor
(also used to treat depression) in the last 3 weeks or you are
taking a reversible MAO-A inhibitor, such as moclobemide.

Taking other medicines
Imipramine Tablets can affect some other medicines you may be taking.

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
