Children and adolescents under 18 years of age
Frosinorshould not be used in the treatment of children and adolescents under 18 years of age.Also, be aware that in patients under 18 years of age, there is a higher risk of adverse effects such as suicidal thoughts, suicidal ideation, and hostility (primarily aggression, confrontational behavior, and irritability) when takingFrosinor. Despite this, your doctor may prescribe Frosinor to patients under 18 years of age when they decide it is the best option for the patient. If your doctor has prescribed Frosinor to you or your child under 18 years of age and you want to discuss this decision, consult your doctor. Inform your doctor if any of the symptoms listed above appear or worsen when you or your child under 18 years of age are takingFrosinor. The long-term effects ofFrosinoron safety, related to growth, maturity, and cognitive and behavioral development in this age group have not yet been demonstrated.
In studies conducted with Frosinor in patients under 18 years of age, the most common adverse effects, which affected less than 1 in 10 children or adolescents, were: an increase in thoughts and attempts of suicide, self-harm, hostile, aggressive, or unfriendly behaviors, loss of appetite, tremors, abnormal sweating, hyperactivity (having too much energy), agitation, unstable emotions (including crying and mood changes), and the appearance of fortuitous cardinals or bleeding (such as nasal bleeding). These effects were also observed in patients included in these studies who did not takeFrosinor, although less frequently.
When discontinuing treatment withFrosinor, some patients under 18 years of age reported adverse effects of withdrawal. These effects were very similar to those observed in adults who discontinued treatment withFrosinor(see section3). In addition, patients under 18 years of age frequently (affecting less than 1 in 10) experienced stomach pain, nervousness, and unstable emotions (including crying, mood changes, self-harm, thoughts and attempts of suicide)
Suicidal thoughts and worsening of depression or anxiety disorder
If you are depressed and/or have anxiety disorders, you may sometimes have thoughts of harming yourself or committing suicide. These may increase at the beginning of treatment with antidepressants, as all these medications take time to take effect, which is usually around two weeks but can be longer in some cases.
This is more likely to happen
- If you have previously had thoughts of suicide or self-harm.
- If you are ayoung adult. There is information from clinical trials that shows an increased risk of suicidal behavior in adults under 25 years of age with psychiatric disorders who were being treated with some antidepressant.
If you have thoughts of harming yourself or committing suicide at any time,consult your doctor or go to the hospital immediately.
It may be helpful for you to explain to a family member or close friend that you are depressed or have anxiety disorders, and ask them to read this leaflet. You can also ask them to tell you if they think your depression or anxiety is getting worse, or if they are concerned about changes in your behavior.
