If so, you must talk to your doctor as soon as you can before taking Mirtazapine tablets. • if you are taking or have recently taken (within the last two weeks) medicines called monoamine oxidase inhibitors (MAO-Is). • If you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking Mirtazapine tablets or other medicinal product(s). Warnings and precautions Talk to your doctor or pharmacist before taking Mirtazapine tablets: • If you are taking buprenorphine-containing medicinal products. The use of these medicines together with Mirtazapine can lead to serotonin syndrome, a potentially lifethreatening condition (see “Other medicines and Mirtazapine tablets.”). Children and adolescents Mirtazapine should normally not be used for children and adolescents under 18 years because efficacy was not demonstrated. Also, you should know that patients under 18 have an increased risk of side-effects such as suicide attempt, suicidal thoughts and hostility (predominantly aggression, oppositional behaviour and anger) when they take this class of medicines. Despite this, your doctor may prescribe Mirtazapine tablets for patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed Mirtazapine tablets for a patient under 18 and you want to discuss this, please go back to your doctor. You should inform your doctor if any of the symptoms listed above develop or worsen when patients under 18 are taking Mirtazapine tablets. Also, the long-term safety effects concerning growth, maturation and cognitive and behavioural development of Mirtazapine in this age group have not yet been demonstrated. In addition, significant weight gain has been observed in this age category more often when treated with Mirtazapine compared with adults. Thoughts of suicide and worsening of your depression If you are depressed 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, and ask them to read this leaflet. You might ask them to tell you if they think your depression is getting worse, or if they are worried about changes in your behaviour.
