Overview

Zoloft is an antidepressant medication belonging to the selective serotonin reuptake inhibitor (SSRI) drug class. It’s the brand name for the generic drug sertraline. It can help treat several mental health conditions, but healthcare professionals primarily use it for depression, generalized anxiety disorder (GAD), and panic disorder.

As with all medications, Zoloft can cause side effects, such as migraine, dizziness, and, most commonly, nausea.

If you experience nausea while taking Zoloft, several methods can help you manage this, such as eating smaller and more frequent meals or sipping on ginger tea.

Why does Zoloft cause nausea?

Zoloft reportedly caused nausea in 26% of adults who took the drug during clinical trials.

When you take an SSRI like Zoloft, your serotonin levels increase. This stimulates serotonin receptors in the brain and gastrointestinal (GI) tract, which can lead to side effects like nausea.

Zoloft-induced nausea may result in the following:

• abdominal pain
• lack of appetite
• vomiting
• feeling uneasy or generally unwell
• sweating

The feeling of nausea typically stops after your body has had time to get used to the drug, which may take several weeks.

Despite the risk of side effects, doctors typically consider the benefits of Zoloft to outweigh the risks of leaving the condition untreated.

Did you know? The majority of serotonin, the chemical affected by Zoloft that improves our mood, is produced in our gut — not our brain. This might be why Zoloft can cause nausea.

What are the other side effects of Zoloft?

In addition to nausea, Zoloft can cause other common side effects, such as:

• diarrhea
• dizziness
• dry mouth
• sweating
• fatigue (low energy)
• indigestion
• difficulties with sexual health

As with any medication, Zoloft may cause an allergic reaction. You should get medical help immediately if you experience any symptoms of an allergic reaction after taking Zoloft. These include:

• skin rash
• difficulty breathing
• swelling of your face, throat, lips, or tongue

While uncommon, Zoloft can cause severe side effects, such as an increased risk of suicidal thoughts. There is a boxed warning for this risk in children and young adults.

If you or someone you know is considering suicide or self-harm, please seek support:

• Call 911 or your local emergency number if you feel it’s an emergency.

How can you manage nausea?

If you experience nausea while taking Zoloft, consider speaking with a healthcare professional. They can offer suggestions to limit Zoloft-induced nausea. These may include:

• eating smaller, more frequent meals
• sucking on hard candy
• taking an antacid or anti-nausea medication
• sipping ginger tea or flat ginger ale
• sipping water

If the nausea remains unmanageable after several weeks, consider speaking with a healthcare professional about all your options. They may have to lower your dose or switch your antidepressant.

How can you prevent nausea when taking Zoloft?

Several things may help prevent nausea from happening when taking Zoloft.

Consider speaking with a healthcare professional, such as a doctor or pharmacist, about whether it can be helpful to take Zoloft at certain times.

For example, taking your medication with a meal or at bedtime may help prevent nausea. However, it’s best not to make any changes to the way you take your medication without speaking with a healthcare professional first.
