The name of your medicine is Trimipramine 10 mg or 25 mg Tablets (called trimipramine in this leaflet). Your tablets contain a medicine called trimipramine. This belongs to a group of medicines called antidepressants.
Trimipramine can be used to treat depression. They are especially useful for treating depression in people who also have problems sleeping, stress (anxiety) or feel irritable and restless (agitation).
- you are allergic (hypersensitive) to trimipramine or any of the other ingredients of Trimipramine Tablets (listed in Section 6 Further Information). Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue
- you have had a heart attack

Do not take this medicine if this applies to you. If you are not sure, talk to your doctor or pharmacist before taking trimipramine.
Thoughts of suicide and worsening of your depression or anxiety disorder
This medicine may be associated with thoughts of self-harm and suicidal behaviour in some people.
Tell someone you trust, who can help you in an emergency, that you are taking this medicine and ask that they read this leaflet
Talk to your trusted person, prescriber or go to a hospital straight away, if after starting this medicine, you have new or worse:
- Feelings of anxiety or irritability
- Feelings of restlessness and agitation
- Extreme increases in activity and difficulty sleeping
- Thoughts of acting on dangerous impulses to harm yourself
- Thoughts about suicide or dying
- Changes in behaviour or mood you, or someone you trust, notices and is worried about
In some people, thoughts of self-harm and suicidal behaviour may be increased when first starting antidepressants. Antidepressants take time to work; and sometimes side effects occur before you or others notice improvements in your mood.
Never stop taking an antidepressant suddenly without first talking to a healthcare professional. Stopping an antidepressant medicine suddenly can cause other symptoms related to withdrawal to occur.
Information from clinical trials has shown the highest risk of thoughts of self-harm and suicidal behaviour, is in adults aged less than 25 years who were treated with an antidepressant but the risk applies to people of all ages treated with these medicines.
