Is Zoloft for OCD worth it? What you need to know.

Zoloft (sertraline) is a commonly prescribed selective serotonin reuptake inhibitor (SSRI) for mental health conditions, including obsessive-compulsive disorder (OCD). If you’re curious about Zoloft for OCD, in this article, we give you the information you need to talk to your healthcare provider about whether it’s right for your OCD treatment.

What is Zoloft?

Zoloft (sertraline) is made by Pfizer and was approved by the U.S. Food and Drug Administration (FDA) to treat depression in 1991. It was approved to treat OCD in 1996. By 2019, it had been used to treat a variety of mental health conditions by roughly 40 million people in the U.S. alone. 

Zoloft is often prescribed for OCD. It’s also prescribed — and FDA-approved — to treat mental health conditions like social anxiety disorder, depression, panic disorder, post-traumatic stress disorder (PTSD), and premenstrual dysphoric disorder (PMDD). It’s also been prescribed off-label for conditions it’s not FDA-approved to treat, including generalized anxiety disorder (GAD), eating disorders, body dysmorphic disorder (BDD), and premature ejaculation.

Zoloft belongs to a class of drugs called serotonin reuptake inhibitors (SSRIs.) 

Serotonin is a natural chemical messenger or neurotransmitter. It sends electrical impulses from neuron to neuron in the brain. While serotonin is usually released and then reabsorbed into the neurons, SSRIs instead block the reabsorption (or reuptake) of serotonin back into the neurons, allowing more serotonin to remain between neurons. This increased level of serotonin between brain cells improves message transmission from cell to cell. 

While low serotonin levels are linked to mood disorders, SSRIs’ ability to increase the serotonin levels between brain cells appears to help relieve symptoms of OCD, depression, and other mental health conditions.

What is OCD?

Obsessive-compulsive disorder or OCD is a mental illness and diagnosis that causes obsessions or unwanted, intrusive thoughts, as well as compulsions or repetitive behaviors. It affects roughly 2.3% of adults in the U.S. and is more common in women than men.

For some people, the obsessive thoughts of OCD revolve around fear of germs or contamination, the need for order or balance, aggressive or taboo thoughts of harm or images related to sexuality, religion or aggression, or ruminations around doubt or decisions. 

Compulsions can take the form of repetitive behaviors like excessive hand washing, checking to see if a door is locked or the stove off, arranging objects in a certain way, seeking validation about memories (false memory OCD), or various other rituals. OCD sufferers think that if they complete the behavior in a specific way, they’ll find relief. But relief doesn’t come.

How is OCD treated with Zoloft?

If you have an OCD diagnosis, it’s best to seek care from a licensed healthcare professional. Your provider may decide to prescribe medication since the standard current treatment for obsessive-compulsive disorder includes both therapy and medication. 

If your provider decides to prescribe Zoloft, you’ll start at a small dose initially before increasing you to the most therapeutic dose. Psychiatrists and primary care physicians can prescribe Zoloft for both adults and children. It’s been found to be an effective long-term treatment for OCD, as well as the symptoms of anxiety and depression related to OCD. 

Does Zoloft work for OCD?

For some people, Zoloft does work for OCD. Studies support the effectiveness of Zoloft for the treatment of OCD. Zoloft for OCD reviews of research suggest that pharmacological treatment has historically been a key component in helping people reduce the severity of OCD symptoms.  

Research indicates that after 12 weeks of Zoloft drug treatment for OCD, quality of life improves for patients. 

Evidence-based research also indicates that the best results occur when OCD patients use an SSRI in combination with cognitive behavioral therapy therapies.

How long does Zoloft take to work for OCD?

Typically Zoloft starts to work in 1 to 2 weeks. Research indicates that, for OCD, it may take up to 12 weeks of treatment to see a significant difference. Full improvements in mood for depression often take 6 to 8 weeks.

It’s important to remember that each individual is different and individual experiences will vary. Your healthcare provider will work with you on the appropriate timeline and dose for your situation.

What does Zoloft do in the brain and body?

Zoloft functions by blocking the reabsorption of serotonin into neurons. This increases the level of serotonin in the gaps between neuron synapses and allows for additional messaging between the neurons or brain cells.

Increased communication between neurons is thought to improve mood and relieve symptoms of depression and anxiety disorders, including OCD. 

What’s the best Zoloft dose for OCD?

Zoloft is available in 25-milligram, 50-milligram, and 100-milligram oral tablets, as well as a 20-milligram/milliliter oral solution. 

The therapeutic dose for Zoloft is typically 50 to 200 milligrams. Your provider will start you off with a low dose, to let you adjust to it and monitor you for potential side effects or reactions Your dose may then be increased over 4 to 6 weeks until you reach your optimal dose or have adverse effects. At least one week between dose changes is recommended. 

Talk with a healthcare provider before starting or adjusting the dose of any medication. Your provider will consider factors such as age, medical history, and your response to treatment to determine the right starting and maintenance dose for you.

How is Zoloft taken?

If you’re pregnant, may become pregnant, or are breastfeeding, your provider may or may not decide Zoloft is inappropriate for you depending on your case.

• Tremors
• Anxiety
• Tingling sensations or “pin-and-needles” (paresthesias)

Some of the popular medications prescribed for OCD include:

Does therapy help OCD?

If you’re diagnosed with OCD, most providers recommend therapy in conjunction with medication treatment for OCD.

Research-based therapeutic modalities like cognitive behavioral therapy (CBT), dialectical behavioral therapy (DBT), and exposure therapy and response prevention (ERP) are used. ERP is considered the best therapy for OCD. 

You’ll likely need to see 2 separate providers — one for therapy and one for medication management. For medication treatment and management, you’ll see a psychiatric medication prescriber. For therapy, you’ll see a licensed therapist.

Therapy may help you address obsessive fears and compulsions, along with stress and anxiety management. Sometimes, family or couple’s therapy may also be indicated to support you in educating your family on how to cope with your mental health diagnosis in the healthiest way possible. 

This collaborative, team approach to treatment can support your neurochemical health while also providing you with practical, evidence-based coping tools and skills.
