Contents of the pack
Frosinor is used for the treatment of depression and/or anxiety disorders in adults.The anxiety disorders for which Frosinor is indicated are: obsessive-compulsive disorder (obsessive thoughts, repetitive behavior), panic disorder (panic attacks, including those caused by agoraphobia, which is the fear of open spaces), social anxiety disorder (fear or avoidance of social contact), post-traumatic stress disorder (anxiety caused by a traumatic event), and generalized anxiety disorder (feeling normally very anxious and nervous).
Frosinor belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). The mechanism of action of Frosinor and other SSRIs is not fully understood, but they work by increasing the level of serotonin in the brain. Properly treating depression or anxiety disorder is important to help you feel better.

If you are in any of these situations, tell your doctor and do not take Frosinor.
Warnings and precautions
Talk to your doctor or pharmacist before starting to take Frosinor
If you are in any of these situationsand have not yet talked to your doctor, ask your doctor how to take Frosinor.
Children and adolescents under 18 years of age
Frosinor should not be used in the treatment of children and adolescents under 18 years of age.Also, you should know that in patients under 18 years of age, there is a greater risk of adverse effects such as suicidal attempts, suicidal thoughts, and hostility (mainly aggression, confrontational behavior, and irritation) when taking Frosinor. Nevertheless, your doctor may prescribe Frosinor to patients under 18 years of age when they decide it is the most convenient for the patient. If your doctor has prescribed Frosinor to you or your child under 18 years of age and you wish to discuss this decision, talk to your doctor. You should inform your doctor if any of the symptoms mentioned above appear or worsen when you or your child under 18 years of age are taking Frosinor. The long-term effects of Frosinor on 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 frequent adverse effects, which affected less than 1 in 10 children or adolescents, were: an increase in suicidal thoughts and attempts, self-harm behaviors, hostile, aggressive, or unfriendly behaviors, loss of appetite, tremors, abnormal sweating, hyperactivity (having too much energy), agitation, unstable emotions (including crying and mood swings), and the appearance of bruises or bleeding (such as nosebleeds). These effects were also observed in patients included in these studies who did not take Frosinor, although with less frequency.
When stopping treatment with Frosinor, in these studies, some of the patients under 18 years of age reported having withdrawal effects. These effects were very similar to those observed in adults who stopped treatment with Frosinor (see section 3). Additionally, patients under 18 years of age frequently experienced (affecting less than 1 in 10) stomach pain, nervousness, and unstable emotions (including crying, mood swings, self-harm behaviors, suicidal thoughts, and attempts).
Suicidal thoughts and worsening of your 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 medicines take time to work, which is usually a few weeks but sometimes may be longer.
This is more likely to happen
If you have thoughts of self-harm or suicide at any time, talk to your doctor or go to the hospital immediately.
It may be helpful for you to tell a relative or close friendthat 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 worried about changes in your behavior.
Important side effects seen with Frosinor
Some patients who take Frosinor develop a disorder called akathisia, and feel restless and unable to sit or stay still. Other patients develop a condition called serotonin syndrome or neuroleptic malignant syndrome, and may have some or all of the following symptoms: feeling very agitated or irritable, confusion, restlessness, feeling hot, sweating, trembling, chills, hallucinations (strange visions or sounds), muscle stiffness, sudden jerky movements, or increased heart rate. The severity can increase and lead to loss of consciousness. Talk to your doctorif you have any of these symptoms. For more information on this or other side effects of Frosinor, see section 4.
Some medicines in the same group as Frosinor (called SSRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after stopping treatment.
Other medicines and Frosinor
Some medicines may change the effect of Frosinor or make some side effects more likely. Frosinor may also change the effect of some medicines. For example:
If you are taking or have recently taken any of these medicines, tell your doctor and ask what you should do. Your doctor may decide to change the dose or prescribe another medicine.

In some studies, an increased risk of malformations, particularly those affecting the heart, has been observed in newborns whose mothers took Frosinor during the first months of pregnancy. In the general population, approximately 1 in 100 newborns is born with a heart malformation. This proportion increased to 2 in 100 newborns in mothers who took Frosinor. Your doctor, in agreement with you, may change your treatment to another medicine or gradually stop Frosinor while you are pregnant. However, depending on your circumstances, your doctor may recommend continuing to take Frosinor.

stiffness or floppiness of the muscles
