Read all of this leaflet carefully before you start taking this medicine, because it contains important information for you.
Contents of the pack:
Sertraline Alter contains sertraline as the active substance. Sertraline belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs); these medicines are used to treat depression and/or anxiety disorders.
Sertraline Alter can be used to treat:
Depression is a clinical illness with symptoms such as feelings of sadness, inability to sleep well or to enjoy life as you used to.
OCD and anxiety disorders are illnesses related to anxiety, with symptoms such as being constantly worried about recurring ideas (obsessions) that lead to repetitive rituals (compulsions).
PTSD is a disorder that can occur after a highly traumatic emotional experience, and has some symptoms similar to depression and anxiety. Social anxiety disorder (social phobia) is an illness related to anxiety. It is characterized by feeling intense anxiety or panic in social situations (e.g., talking to strangers, speaking in public, eating or drinking in front of others, or worrying about behaving shamefully).
Your doctor has considered that this medicine is suitable for treating your illness.
If you are not sure why you have been prescribed sertraline, you should consult your doctor.
Do not take Sertraline Alter:
Warnings and precautions
Consult your doctor or pharmacist before starting treatment with Sertraline Alter.
Medicines are not always suitable for everyone. Before starting treatment with Sertraline Alter, tell your doctor if you have or have had any of the following:
Restlessness/Akathisia
The use of sertraline has been associated with unpleasant restlessness and a need to move, often accompanied by an inability to sit or stand still (akathisia). This occurs more often during the first few weeks of treatment. Increasing the dose may be harmful, so if you develop these symptoms, you should contact your doctor.
Withdrawal symptoms
Side effects related to stopping treatment (withdrawal symptoms) are common, particularly if treatment is stopped abruptly (see section 3. If you stop taking Sertraline and section 4. Possible side effects).
The risk of experiencing withdrawal symptoms depends on the duration of treatment, the dose, and the rate at which the dose is reduced. Generally, these symptoms are mild or moderate. However, in some patients, they can be severe. These symptoms usually occur during the first few days after stopping treatment. In general, these symptoms usually resolve on their own and normally disappear within two weeks. In some patients, they can last longer (2-3 months or more). It is recommended that when stopping treatment with sertraline, the dose should be gradually reduced over a period of several weeks or even months, and you should always agree with your doctor on the best way to stop treatment.
Thoughts of suicide and worsening of your depression or anxiety
If you are depressed and/or have anxiety disorders, you may sometimes have thoughts of harming yourself or committing suicide. This may increase at the beginning of treatment with antidepressants, due to the fact that these medicines take time to work, which is usually a few weeks, but sometimes can be longer.
This is more likely to happen
If you have thoughts of harming yourself or committing suicide at any time, contact your doctor or go to the hospital immediately.
It may be helpful for you to tell a relative or close friend that you are depressed or have an anxiety disorder, 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.
Sexual problems
Some medicines in the same group as Sertraline Alter (called SSRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after stopping treatment.
Children and adolescents
Sertraline should not normally be used in the treatment of children and adolescents under 18 years old, except in patients with obsessive-compulsive disorder (OCD). Patients under 18 years old have a higher risk of side effects such as suicidal attempts, thoughts of self-harm or suicide (suicidal ideas), and hostility (mainly aggression, confrontational behavior, and anger) when they are treated with this class of medicines. Nevertheless, your doctor may decide to prescribe Sertraline Alter to a patient under 18 years old if they consider it is in the patient's best interest. If your doctor has prescribed Sertraline Alter for you and you are under 18 years old and wish to discuss this decision, please go back to your doctor. You should tell your doctor if any of the symptoms mentioned above occur or worsen when you are taking Sertraline Alter. The long-term safety of sertraline in terms of growth, maturation, and cognitive and behavioral development has been evaluated in a long-term study in over 900 children aged 6 to 16 years who were monitored for a period of 3 years. In general, the study results showed that children treated with sertraline developed normally, except for a slight increase in weight in those treated with a higher dose.
Other medicines and Sertraline
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Some medicines may affect the way Sertraline Alter works, or Sertraline Alter may reduce the effectiveness of other medicines that you are taking at the same time.

Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
The safety of sertraline in pregnant women has not been fully established. If you are pregnant, sertraline will only be given to you if your doctor considers that the benefit to you outweighs any possible risk to the developing baby.
If you take Sertraline in the final stages of pregnancy, there may be an increased risk of heavy vaginal bleeding shortly after delivery, especially if you have a history of bleeding disorders. Your doctor or midwife should know that you are taking Sertraline so they can advise you.
When taken during pregnancy, especially during the last three months, medicines like Sertraline Alter may increase the risk of a serious disease in babies called persistent pulmonary hypertension (PPHN), which makes the baby breathe faster and have a bluish appearance. These symptoms usually start within the first 24 hours after birth. If this happens to your baby, contact your midwife and/or doctor immediately.
Your newborn baby may have other illnesses, which usually appear within the first 24 hours after birth. The symptoms include:
If your baby has any of these symptoms at birth, or you are worried about your baby's health, consult your doctor or midwife for advice.
There are indications that sertraline passes into breast milk. Therefore, sertraline can only be used in breastfeeding women if the doctor considers that the benefit to the mother outweighs any possible risk to the baby.
