Sertraline is an antidepressant used for the treatment of depression, obsessive compulsive disorder, panic disorder or social anxiety. It works by increasing the availability of serotonin in the brain, which is a neurotransmitter that is responsible for regulating mood and well-being.
This medication may also be prescribed to relieve the symptoms of premenstrual syndrome (PMS) or premenstrual dysphoric disorder, such as irritability, bloating and mood changes.
Sertraline can be obtained with a prescription at a pharmacy in 25 mg, 50 mg or 100 mg tablets, as the generic "sertraline hydrochloride" or under the brand names Zoloft.

What it’s used for
Sertraline is prescribed for the treatment of:
- Depression
- Obsessive compulsive disorder (OCD)
- Panic syndrome, with or without agoraphobia
- Social phobia
- Post-traumatic stress disorder
Sertraline can additionally be indicated to relieve symptoms of premenstrual syndrome and/or premenstrual dysphoric disorder.
Sertraline should only be used as prescribed and with regular follow-up with a psychiatrist or family doctor, who can assess the patient’s response to treatment and the emergence of side effects.
How it works
Sertraline acts in the body by selectively inhibiting the reuptake of serotonin. This leads to an increase of sertraline levels in the brain.
Serotonin is a neurotransmitter known as the “happiness hormone”, and it helps to regulate mood, sleep, anxiety and depression. Learn more about serotonin and how low levels can affect you.
How to take
Sertraline should be taken orally, with a glass of water, before or after a meal. It is taken as a single daily dose, ideally at the same time every day.
Dosing for sertraline adults varies depending on the condition being treated. General doses are as follows:
- Depression and obsessive compulsive disorder (OCD): the normally recommended dose is one 50 mg tablet of sertraline per day;
- Panic syndrome, post-traumatic stress disorder (PTSD) and social phobia: the initial dose is one 25 mg tablet per day (or ½ tablet of 50 mg), which can be increased by the doctor to 50 mg per day after 1 week of treatment;
- Premenstrual tension (PMS) and/or premenstrual dysphoric disorder (PMDD): the normally recommended dose is 1 tablet of 50 mg of sertraline per day, which can be used continuously or starting 14 days before menstruation, You should stop using it on the first day of your period and repeat this course of use every month.
The dose of sertraline for adults can be gradually increased to a maximum of 200 mg/day, as prescribed by your doctor and according to the condition being treated.
Children over 6 years of age can be prescribed sertraline for the treatment of depression or obsessive compulsive disorder (OCD). The initial recommended dose is 25 mg per day for children between 6 and 12 years of age. This can then be increased by the doctor to 50 mg per day, depending on the response to treatment.
For children between 13 and 17 years old, the initial recommended dose of sertraline is 50 mg per day.
What to do if you forget to take it
If you forget to take sertraline, take the forgotten dose as soon as you remember, and then take your next dose at the regular scheduled time. However, if you forgot to take the current dose of sertraline close to the time of the next dose, skip the missed dose and wait for the usually time of the next one.
You should not take 2 doses at the same time to try to make up for a missed dose. If you are unsure how to proceed, consult your prescriber or pharmacist for further guidance.
